Introduction
Introduction
The primary purpose of this document is to explain any peculiarities of the decoding of each protocol. Click in the list above on each protocol name to get any information specific to decodes with that name.If you don't understand the advanced information (IRP notation, etc.) at the start of each of those entries, don't worry about that and please don't let it stop you from reading the text below that. In many cases there is important protocol-specific information you will need in order to use the data from the decode.
Decode problems
The decoder only looks at one IR signal at a time. Sometimes it gives contradictory results for a signal. The best way to determine which result is correct is to compare with the decodes of other signals for the same device.Spurious decodes and non-robust protocols
Most IR protocols have enough internal consistency checks that the decoder can reliably tell whether that protocol is present in a learned signal and can reliably decode the device, subdevice and OBC numbers. If the signal is learned badly enough, the decoder may fail to find that protocol in the signal. But it is very unlikely to decode it with the wrong numbers or to imagine that protocol is a bad learn of something else.Some protocols are not robust. A totally unrelated IR signal can accidentally fit the pattern of such a protocol resulting in a spurious decode. When you get a decode for a non-robust protocol you need to exercise some judgment about whether to believe or ignore that decode. Usually you can decide based on decodes of other signals of the same device.
EFC, JP1, KeyMoves, Upgrades, etc.
Much of this document assumes DecodeIr is being used with JP1 or at least with a JP1 capable remote. But some people will be using DecodeIr with other types of remote.If your remote is not OneForAll brand and is not one of the models of Radio Shack (or a few other brands) that uses the same design as OneForAll, then everything this document says about JP1, KeyMoves, Upgrades, KM, RM (RemoteMaster), and EFC numbers has no meaning for your use. Just ignore those references and the rest of this doc should apply to your use. Also ignore the EFC numbers in the actual output from DecodeIr.
If you are using a OneForAll type remote but have neither a JP1 cable nor a remote model that can be upgraded by .wav file, then nothing about Upgrades, KM, RM, and OBC numbers applies to your use. If the decodes you get include EFC numbers and you know (or can ask in a forum) which setup code is right (corresponds to the protocol, device and subdevice of the decode) then you can use those EFC numbers in KeyMoves. Note that the decoding process cannot directly tell you which setup code is needed to generate the signal. If you post a question in an appropriate forum with the protocol name, device number, subdevice number, and which model OneForAll type remote you have, someone will probably identify the setup code for you.
Toggle bits
Several different protocols include something called a toggle bit. This means that each command has two or more different forms. Some protocols (e.g. RC5) alternate the toggle on each key press, while others change the toggle to indicate a start or end frame.An alternating toggle lets the device receiving the commands distinguish between a long press of a button and two short presses. For example, if you press and hold the '1' button the remote continuously sends repeats of a single form of the '1' command. But if you press '1', release it and press it again the remote will switch to the other form of the command for the second press.
When you learn such a command you are capturing just one form of the command and every use will send that same form. If you use that learned signal and press the same button twice in a row, the device receiving the signal will see that as one long press rather than two short ones. For keys, such as digits, where one long press has a different meaning than two short presses, that gets quite inconvenient.
With OneForAll type remotes, using an upgrade or KeyMove will solve that problem.
For some of these protocols, for some models of Pronto remote, there is a condensed encoding of the Pronto Hex that will solve the problem.
Repeat frames and dittos
DecodeIR v2.37 and later versions have a look-ahead facility that is not present in earlier ones. This distinguishes between two styles of data passed to them by the calling application. The remote control programming applications IR.exe and RMIR pass signals learned by a UEI remote that has itself performed a partial analysis of the signal. The data is passed in a structured form, divided into Once, Repeat and Extra sections. The data in each of these sections can be viewed in IR.exe if the "Force Learned Timings" option on the Advanced menu is selected. Because of this analysis, DecodeIR does not see the original signal in full and cannot determine such things as the number of repeats of the signal that were sent. Other applications such as the IRScope software for the IR Widget send the entire signal as unstructured data, which enables IR.exe to identify the number of repeats.
The look-ahead facility checks successive frames within a single signal to see if they are repeats – either identical repeats or, in certain protocols, frames of a repeat sequence that have a distinctive marker in either the start or end frame, or both, of the sequence. If a protocol has distinctive start or end frame markers and either or both of the start and end frames are missing, this is reported in the Misc field of the decode (but at present this may not be implemented for all protocols with such markers). If the data has been passed in an unstructured form then the number of repeats in the signal will also be reported in the Misc field in a form like "4 frames", or in version 2.39 and later, "+ 3 copies".
In the case of unstructured data, DecodeIR v2.38 extends the look-ahead to protocols in which repeat action is signalled not by a full repeat of the frame but by a much shorter frame that does not carry the signal data (or occasionally carries just part of this data). These frames serve as "ditto marks". If present then the number of such frames is reported in the Misc field in a form like "3 dittos", or in version 2.39 and later, "+ 3 dittos". If there are no repeat frames or ditto marks, then to avoid ambiguity this is reported as "no repeat".
Mini Combos
Some UEI protocol executors are "mini-combos". This means they support more than one device number within one setup code using single-byte hex commands. There will be more than one possible EFC number for each OBC number. DecodeIr can't determine the correct EFC number by looking at the IR signal, because it isn't a characteristic of the signal. It is a characteristic of the fixed data used in creation of the setup code.DecodeIr will list two or three different EFC numbers for each OBC number. The sequence of those two or three EFC numbers is consistent across all the decodes. So once you find out which position in that list is correct for one OBC of a given device number and setup code, that position will be correct for the EFC list of any other OBC of the same device and setup code (except that for RC-5 the decision of whether or not the OBC number is above 63 is treated as being part of the device number).
Brief and incomplete guide to reading IRP
General: {carrier frequency, time unit, sequencing rule} Mitsubishi:{32.6k,300}<1,-3|1,-7>(D:8,F:8,1,-80)+
Carrier Frequency: Hz; e.g. 38.3k; default is 0k--no modulation
Time Unit: Integer that can represent durations. Suffix u (default) is microseconds, p denotes number of pulses of the carrier.
Sequencing Rule: lsb|msb; lsb (default) means the least significant bit of a binary form is sent first.
BitSpec: Rule for the translating bit sequences to duration sequences. <ZeroPulseSeq|OnePulseSeq|TwoPulseSeq....>. Most IR protocols use only <ZeroPulseSeq|OnePulseSeq>, and the sequence is simply OnDuration,OffDuration. Example: NEC uses <1,-1|1,-3>
Bitfield: D:NumberOfBits:StartingBit. E.g. if D=71= 01000111, D:2:5 means x10xxxxx. D:2:5 = 10b = 2. ~ is the bitwise complement operator. ~D =10111000. Specifying the StartingBit is optional. D:6 is equivalent to D:6:0.
IRStream: The sequence of data. Enclosed in parentheses, items separated by commas. A trailing + means send one or more times. A trailing 3 means send 3 times; 3+ means at least 3 times. A trailing * means send zero or more times. NEC2: {38.4k,564}<1,-1|1,-3>(16,-8,D:8,S:8,F:8,~F:8,1,-78)+
Durations: no suffix means duration is expressed in Time Units, as defined above. m is milliseconds, u microsec, p pulses. No prefix means a flash, a preceeding - (minus) means a gap.
Extent: A gap which trails a signal. The trailing gap is adjusted to make the total length of signal plus trailing gap equal to the extent. Notation is like a gap duration, except ^ replaces the minus sign. RC-5:(1:1,~F:1:6,T:1,D:5,F:6,^114m)+
Expressions: names, numbers and bitfields connected by standard symbols for arithmetic and logical operations. Enclosed in parentheses. Panasonic: {37k,432}<1,-1|1,-3>(8,-4,2:8,32:8,D:8,S:8,F:8,(D^S^F):8,1,-173)+
Permitted operators in decreasing order of precedence:
unary – (negation)
** (exponentiation)
* /, % (multiplication, integer division, modulo) (* is also used in IRStreams)
+, – (addition, subtraction (+ is also used in IRStreams)
& (bitwise AND)
^ (exclusive OR) (also used in extents)
| (OR)
~ (complement) is permitted in Bitfields
Definitions: expressions separated by commas, enclosed in curly brackets. GI Cable: {38.7k,490}<1,-4.5|1,-9>(18,-9,F:8,D:4,C:4,1,-84,(18,-4.5,1,-178)*) {C = -(D + F:4 + F:4:4)}
Assignments: For example T=T+1, which can be used to describe the RC-5 toggle bit.
Variations: Up to 3 expressions enclosed in square brackets. The first variation is sent on the first transmission, second for middle transmissons, and the third for the final transmission. E.g. the Zaptor toggle bit is zero until the last frame: [T=0] [T=0] [T=1]
The IRP specification by Graham Dixon
Practical explanation of IR signals and IRP by Vicky Getz48-NEC
If you get a decode whose protocol name is simply "48-NEC" that indicates the learned signal is not complete (usually caused by not holding the original remote's button long enough during learning). Enough of the signal is present to accurately determining the device, subdevice and OBC numbers. But not enough is present to determine whether the protocol is 48-NEC1 or 48-NEC2.48-NEC1
IRP notation: {564}<1,-1|1,-3>(16,-8,D:8,S:8,F:8,~F:8,E:8,~E:8,1,-??,(16,-4,1,-??)*)
EFC translation: LSBThis protocol signals repeats by the use of dittos.
48-NEC2
IRP notation: {564}<1,-1|1,-3>(16,-8,D:8,S:8,F:8,~F:8,E:8,~E:8,1,-??)+
EFC translation: LSBAdNotam
IRP notation: {35.7Khz,895,msb}<1,-1|1,-3>(0:1,1:1,D:6,F:6,^114m)+
Very similar to RC5, except AdNotam uses two start bits, and no toggle bit.
AirAsync
IRP notation: {37.7Khz,840}<1|-1>( 1,B:8,-2 ... )This protocol uses asynchronous data transmission that sends an 8-bit byte with 1 start bit, 8 data bits and 2 stop bits. The minimum signal is one byte. The protocol is reported as AirAsyncn-xx.yy. ... where n is the number of bytes and xx, yy, ... are the byte values in hexadecimal notation.
AirB?-????
This is not a robust protocol, so spurious decodes are likely. If you see this decode from something other than an IR keyboard, you should probably ignore it.
Aiwa
UEI protocol: 005E or 009E
IRP notation: {38k,550}<1,-1|1,-3>(16,-8,D:8,S:5,~D:8,~S:5,F:8,~F:8,1,-42,(16,-8,1,-165)*)
EFC translation: LSBThis protocol signals repeats by the use of dittos.
The EFC numbering varies among the KM and RM versions of Aiwa. Using OBC numbers is less confusing.
When using a non-combo version of Aiwa in KM, you must combine the device and subdevice numbers as device+256*subdevice to get the number KM calls "Device Code". (Since subdevice is usually zero, that combination is trivial). In Aiwa combo in KM you use the subdevice as "parameter" (on the setup sheet) and put the device in the byte2 column on the functions sheet. RM follows DecodeIr's naming of Device and Subdevice.
AK
Documentation not written yet.Akai
UEI protocol: 000D
IRP notation: {38k,289}<1,-2.6|1,-6.3>(D:3,F:7,1,^25.3m)+
EFC translation: LSB comp prefixed with last device bitThis is not a robust protocol, so spurious decodes are likely.
As of version 8.31, KM does not translate device to fixed data, nor OBC to EFC according to the same rules used by DecodeIr. RM does translate consistently with DecodeIr, so you may find it easier to use RM. If you use KM, you must change the device number as follows:
- Decoded device 0 or 4 --> KM device 3
- Decoded device 1 or 5 --> KM device 2
- Decoded device 2 or 6 --> KM device 1
- Decoded device 3 or 7 --> KM device 0
Also (in KM) you should use the EFC number from the decode not the OBC number. Akai protocol uses the same EFC numbering across all JP1 remotes, so use of EFC is safe. KM uses different OBC numbering than RM and DecodeIr, so use of OBCs isn't safe.
Amino
UEI protocol: 019C
IRP notation: {56.0k,268,msb}<-1,1|1,-1>[T=1] [T=0] (7,-6,3,D:4,1:1,T:1,1:2,0:8,F:8,15:4,C:4,-79m)+
-----Variant: {36.0k,268,msb}<-1,1|1,-1>[T=1] [T=0] (7,-6,3,D:4,1:1,T:1,1:2,0:8,F:8,15:4,C:4,-79m)+
{C =(D:4+4*T+9+F:4+F:4:4+15)&15} [the arithmetic sum of the first 7 nibbles mod 15]
T=1 for the first frame and T=0 for all repeat frames.
DecodeIR v2.43 checks T and will report in the Misc field if the start or end frame is missing. Amino equipment use both 36 and 56KHz, but the duration of the half-bit is always 268. Zaptor is a closely related protocol which for which the half-bit duration is 330. IRDecode v2.43 distinguishes between Amino and Zaptor in order of priority by 1)the position of the toggle bit, 2)the value of the next to last nibble, and 3)the measured duration of a half-bit.

Anthem framing is very similar to NEC, and also uses 32 bits of data. However, the leadout is much shorter. The signal is sent at least3 times.Apple

C=1 if the number of 1 bits in the fields F and I is even. I is the remote ID.Apple uses the same framing as NEC1, with D=238 in normal use, 224 while pairing. S=135

EFC translation: 5-bit LSBThis is not a robust protocol, so spurious decodes are likely.
Async
This protocol uses asynchronous data transmission that sends an 8-bit byte with 1 start bit, 8 data bits and 1 stop bit. The minimum signal is four bytes. The protocol is reported as Asyncn:min-max:aa.bb...yy.zz where n is the number of bytes, min-max is the range of durations in microseconds that was taken as a single bit and aa.bb...yy.zz are the first two and last two byte values in hexadecimal notation.

EFC translation: 7-bit MSB.The repeat frames are not all identical. T toggles within a single signal, with T=0 for the start frame and T=1 for all repeats. DecodeIR v2.37 and later check T and will report in the Misc field if the start frame is missing.
Denon, Denon{1} and Denon{2}
IRP notation: {38k,264}<1,-3|1,-7>(D:5,F:8,0:2,1,-165,D:5,~F:8,3:2,1,-165)+
EFC translation: LSBA Denon signal has two halves, either one of which is enough to fully decode the information. A significant fraction of Denon learned signals contain just one half or have the halves separated so that DecodeIr can't process them together. When one half is seen separate from the other, DecodeIr will name the protocol Denon{1} or Denon{2} depending on which half is decoded. Denon, Denon{1} and Denon{2} all represent the same protocol when they are correct. But only Denon is robust. A Denon{1} or Denon{2} decode might be spurious.
Denon-K
UEI protocol: 00CD
IRP notation: {37k,432}<1,-1,1,-3>(8,-4,84:8,50:8,0:4,D:4,S:4,F:12,((D*16)^S^(F*16)^(F:8:4)):8,1,-173)+
EFC translation: LSB compDenon-K is the member of the Kaseikyo family with OEM_code1=84 and OEM_code2=50.
Denon-K uses the same check byte rules as Panasonic protocol, but uses the data bits differently. The Panasonic Combo protocol in KM can be used with some difficulty to produce Denon-K signals. The Denon-K choice in RM uses the same protocol executor as Panasonic combo, but computes the hex commands based on Denon's use of the Kaseikyo data bits.

DirecTV
IRP notation: {38k,600,msb}<1,-1|1,-2|2,-1|2,-2>(5,(5,-2,D:4,F:8,C:4,1,-50)+) {C=7*(F:2:6)+5*(F:2:4)+3*(F:2:2)+(F:2)}
EFC translation: MSBThere are six variants of the DirecTV protocol, distinguished in RemoteMaster by the parameter "Parm" on the Setup page. The Parm value is shown in the Misc field of DecodeIR. The IRP notation above corresponds to the default Parm=3. The various Parm values correspond to three different frequencies (the 38k in the above) and two different lead-out times (the -50 in the above). The corresponding values are:
- Parm=0 : 40k, -15
- Parm=1 : 40k, -50
- Parm=2 : 38k, -15
- Parm=3 : 38k, -50
- Parm=4 : 57k, -15
- Parm=5 : 57k, -50
Portions of a dirty learn of a Sony signal may look like a DirecTV signal. So, if you get a DirecTV decode together with a plausible Sony decode, believe the Sony decode and ignore the DirecTV. If you get a DirecTV decode without a Sony decode for some functions of a Sony device, try relearning them; a DirecTV decode for a signal meant for a Sony device is not likely to be correct.
This protocol was called Russound in versions of DecodeIR earlier than 2.40.
Dishplayer
UEI protocol: 010F
IRP notation: {38.4k,535,msb}<1,-5|1,-3>(1,-11,(F:6,U:5,D:2,1,-11)+)
EFC translation: Not available in this version of DecodeIrThis is not a robust protocol, so spurious decodes are likely.
Dish_Network
UEI protocol: 0002
IRP notation: {57.6k,400}<1,-7|1,-4>(1,-15,(F:-6,U:5,D:5,1,-15)+)
EFC translation: MSB comp 6 function bits followed by LSB comp low 2 unit bits.This is not a robust protocol, so spurious decodes are likely.
The unit number shows up in the Subdevice field of DecodeIr's output. In KM, the "unit code" is one greater than the unit number. So you must take the Subdevice from the decode and add one to it and use that as the "unit code" in KM.
There are two variants of the protocol executor for DishNetwork with different but compatible EFC numbering. The decoded EFC should work for both. But the results may be less confusing if you use OBC numbers in KM or RM.

IRP notation: (Toshiba specification) K=(D:3,H:1,A:1,B:2,F:6) {37.9k,422}<1,-3|3,-1>(K,-34,K) for A=1 or B=1
{37.9k,422}<1,-3|3,-1>(K,-34,K,-88,K,-34,K)+ for H=1. Exactly one of H, A, or B can have a value of 1. If H=1 the signal can be sent repeatedly, and F can take any 6 bit value. If A or B=1, the signal is sent once only per button press, and only a single bit of F can be non-zero.IRP notation: (JP1) K=(D:3,H:1,F:8) {37.9k,422}<1,-3|3,-1>(K,-34,K) for H=0.
{37.9k,422}<1,-3|3,-1>(K,-34,K,-88,K,-34,K)+ for H=1.
A and B are subsumed into F, and the value of H is computed in the executor. H=A^B.
EFC translation: lsb, but not computed in DecodeIR.
DecodeIR reports H as the subdevice. This is useful when making a Pronto Hex file, or other description based on durations. Remotes with executors (e.g. UEI remotes) normally compute the value of H in the executor, and the "subdevice" is not needed as a parameter.Fujitsu
UEI protocol: 00F8
IRP notation: {37k,432}<1,-1,1,-3>(8,-4,20:8,99:8,X:4,E:4,D:8,S:8,F:8,1,-110)+
EFC translation: LSB compFujitsu is the member of the Kaseikyo family with OEM_code1=20 and OEM_code2=99.
There is no check byte, so the risk of an incorrectly decoded OBC is much higher than in other Kaseikyo protocols.
00F8 requires 2-byte hex commands, so the decoded EFC number is generally not useful. Use OBC number in upgrades or to compute Hex commands.

EFC translation: LSBThis protocol signals repeats by the use of dittos. When the {1} is shown as part of the protocol name for G.I. Cable, it just means that the repeat part of the signal is not present. That doesn't indicate any difference in the actual protocol nor even any unreliability in the decode. It may indicate that use of the learned signal will be less reliable, so you have more than usual reason to replace it with a KeyMove, Upgrade or cleaned up version.

EFC translation: NONEThis is a moderately robust protocol, but spurious decodes are still possible.
The official (UEI) protocol executor for G.I.4DTV does not support EFC numbers. If you are creating an upgrade in KM or RM you should use OBC numbers, not EFC numbers. If you need the Hex Cmd for a KeyMove, you should use the functions sheet of KM or RM to compute it for you from the OBC and device number.

JVC and JVC{2}

IRP notation: {38k,525}<1,-1|1,-3>(16,-8,(D:8,F:8,1,-45)+)
EFC translation: LSB compJVC{2} indicates a JVC signal from which the lead-in is missing. The JVC protocol has lead-in on only the first frame, so it is quite easy to have it missing from a learned signal. So when JVC{2} is correct, it means the same as JVC. But JVC{2} is not robust, so spurious decodes are likely. It is also very similar in structure and timing to Mitsubishi protocol, so that DecodeIr has difficulty distinguishing one from the other. The device number, OBC and EFC are all encoded the same way between the two. So if you have JVC{2} decodes that you have reason to suspect should actually be Mitsubishi, you can try using them as Mitsubishi without changing the numbers. However, true Mitsubishi signals will not misdecode as JVC, just as JVC{2}. So if some of the signals for your device decode as JVC and others as JVC{2}, you should trust all those decodes and not try Mitsubishi.

Panasonic protocol uses the same check byte rules as JVC-48, so you might want use the (more flexible) Panasonic entries in KM or RM to produce a JVC-48 upgrade (by changing the OEM_code1 and OEM_code2 values). For simple JVC-48 upgrades you get exactly the same results by directly selecting the "JVC-48" protocol.

Kaseikyo is a family of protocols that includes Panasonic, Mitsubishi-K, Fujitsu, Sharp-DVD and Teac-K. Each protocol in the Kaseikyo family is identified by two numbers, known as OEM_code1 and OEM_code2.
Most members of the family have minor structural differences from the generic form. In those cases DecodeIR checks for the specific details (based on the OEM codes) and if they are correct reports the protocol by name (see Panasonic and Teak-K below).
In the few cases where the structure exactly fits my understanding of the Kaseikyo spec, DecodeIR reports it as Kaseikyo-???-??? replacing the first ??? by the OEM_code1 and the second ??? by the OEM_code2.

EFC translation: LSB compThis is the nominal form of the Kaseikyo. It is most commonly seen with OEM codes 170.90, which indicates "Sharp". I assume (haven't tested) that the SharpDVD protocol in KM generates these Kaseikyo-170-90 signals. We have also seen this protocol with OEM codes 3.32. I'm not sure what manufacturer that indicates.
The Kaseikyo protocol in KM seems to be designed to produce this nominal form of Kaseikyo for any specified OEM codes and any constant value of E. That should be the way to reproduce any Kaseikyo-???-??? decode other than SharpDVD, and might be better than SharpDVD for the Kaseikyo-170-90 signals.
Kaseikyo56
Kaseikyo56 is a lengthened version of the Kaseikyo family of protocols. It has the same OEM codes indicating the same manufacturers as Kaseikyo, and it has the same variation (by manufacturer) in check byte and other details as Kaseikyo.Kaseikyo56-???-???

EFC translation: MSB of decoded signal.This is an unusual protocol in that an 8-bit device code and 8-bit OBC are encoded in a 24-bit error-correcting code as the X of the IRP notation. This is constructed as follows. First two parity bits are appended to the 16 data bits to give even parity for the two sets of 9 bits taken alternately. The resulting 18-bit sequence is then treated as 6 octal digits (0-7) expressed in 3-bit binary code. These are then re-coded in the 3-bit Gray code (also called, more descriptively, the reflected-binary code) with a parity bit to give odd parity, so giving 6 4-bit groups treated as a single 24-bit sequence. The whole thing allows any single-bit error in transmission to be identified and corrected.

Technically it is RC6-6-32 with the standard toggle bit zero, with the OEM1 field equal to 128, and with a nonstandard (for the RC6 family) toggle bit added. If all those rules are met, DecodeIr will display the name as "MCE" and with the OEM2 field moved to the subdevice position. Otherwise it will display RC6-6-32.
As of version 8.31, KM does not have built-in support for this protocol, but there are KM format upgrade files available for Media Center (built by an expert who isn't limited to KM's built-in protocols). Those upgrades should be adaptable to any RC6-6-32 code set (by changing the fixed data), if the one you have doesn't already match the upgrade.
RM version 1.16 has support for RC6-6-32, which can be used for MCE upgrades. Version 1.17 will also have direct support for MCE

So if you have Mitsubishi decodes that you have reason to suspect should actually be JVC, you can try using them as JVC without changing the numbers.

NEC
NEC is a family of similar protocols including NEC1, NEC2, Tivo, Pioneer, Apple, NECx1 and NECx2. If you get a decode whose protocol name is simply "NEC" that indicates the learned signal is not complete (usually caused by not holding the original remote's button long enough during learning). Enough of the signal is present to accurately determine the device, subdevice and OBC numbers. But not enough is present to determine whether the protocol is NEC1 or NEC2.Difference between NEC1 and NEC2
The difference between NEC1 and NEC2 only affects the signal sent by a long keypress. A short press sends the same signal in NEC1 and NEC2.Variant IRstreams in NEC protocols
For NEC1, NEC2, NECx1, and NECx2 protocols, the IRstream contains D:8,S:8,F:8,~F:8
However, some manufacturers (especially Yamaha and Onkyo) are breaking the "rule" that the 4th byte should be ~F:8
Version 2.42 decodes these variants by adding suffixes to the protocol name depending on the IRstream:
-y1: D:8,S:8,F:8,~F:7,F:1:7 (complement all of F except the MSB)
-y2: D:8,S:8,F:8,F:1,~F:7:1 (complement all of F except the LSB)
-y3: D:8,S:8,F:8,F:1,~F:6:1,F:1:7 (complement all of F except MSB and LSB)
-f16: D:8,S:8,F:8,E:8 (no relationship between the 3rd and 4th bytes)

EFC translation: LSB compA few devices use NEC1 protocol at 40Khz, rather than the typical frequency. When getting a decode of NEC1, if you notice that the frequency is closer to 40Khz than to 38Khz, examine multiple learns from the same device to estimate whether the 40Khz frequency is a learning error or a true characteristic of the device. If the 40Khz is correct, there are methods in JP1, or MakeHex (whichever you are using) to reproduce NEC1 at 40Khz rather than the usual frequency.
NEC2
IRP notation: {38.4k,564}<1,-1|1,-3>(16,-8,D:8,S:8,F:8,~F:8,1,-78)+
EFC translation: LSB compPioneer is distinguished from NEC2 only by frequency. So if your learning system does not learn frequency accurately, it won't accurately distinguish Pioneer from NEC2. All Pioneer signals should have a device number in the range 160 to 175 and no subdevice. No NEC2 signal should fit those rules. So you usually can determine whether the decision (by frequency) was wrong by checking the device numbers.
NECx
If you get a decode whose protocol name is simply "NECx" that indicates the learned signal is not complete (usually caused by not holding the original remote's button long enough during learning). Enough of the signal is present to accurately determining the device, subdevice and OBC numbers. But not enough is present to determine the exact protocol, which is probably NECx1 or NECx2. This incomplete learn also makes it harder to distinguish NEC from NECx, so a decode of "NECx" might be NEC1 or NEC2 or even Tivo or Pioneer.NECx1

IRP notation: {42.3K, 3000}<1,-3,1,-7|1,-7,1,-3>(F:5,1,-27)+This protocol is a very limited design. We have seen it used only in the UEI setup code TV/0159, which is for some TVs brand named Fisher, Sanyo and Sears. It is not likely that any other code set uses this protocol. So if you get a correct decode of pid-0083 you probably have a TV that can be controlled by the TV/0159 setup code.
As of version 8.31, KM does not translate OBC to EFC according to the same rules used by DecodeIr. RM does translate consistently with DecodeIr, so you may find it easier to use RM. If you use KM, you should use the EFC number from the decode not the OBC number. Pid-0083 protocol uses the same EFC numbering across all JP1 remotes, so use of EFC is safe. KM uses different OBC numbering than RM and DecodeIr, so use of OBCs isn't safe.
Pioneer

EFC translation: LSB compPioneer is distinguished from NEC2 only by frequency. So if your learning system does not learn frequency accurately, it won't accurately distinguish Pioneer from NEC2. All Pioneer signals should have a device number in the range 160 to 175 and no subdevice. No NEC2 signal should fit those rules. So you usually can determine whether the decision (by frequency) was wrong by checking the device numbers.
Many Pioneer commands are sent as combinations of two different Pioneer signals. This version of DecodeIr does not associate the two signals together into one command. It decodes them separately. If you get more than one of the same OBC from decoding a learned signal, that just means the learning system failed to understand the repeat pattern. It does not mean a two part signal. But if there are two different OBCs (with the same or different device numbers) you have a two part Pioneer signal.
Including a two part Pioneer signal in a KeyMove or upgrade is a complex process that requires a good understanding of Pioneer signals and of the Pioneer support in KM. The signals don't vary much among related Pioneer models. So the best way to get an upgrade or hex cmd including such signals is to look through existing Pioneer upgrades in the JP1 group and find one that already includes the same (or nearly same) signal.

In versions of DecodeIR prior to v2.40, RCA(Old) was decoded as a frame of RCA{1} followed usually by a frame of RCA. The second frame now no longer appears, so the protocol has been renamed to correspond to that used in KM and RM.

EFC translation: 6-bit MSB compRECS80 is a family of related protocols with the same structure, but different timing. See also Velleman
These are moderately non robust protocols, so spurious decodes are possible.
The timing differences are not definitive enough for DecodeIr to identify which RECS80 version is which. Instead it displays the timing information in the "Misc" field of the output. That will be three numbers formatted as in this example: (157/5048/7572).
Using those three numbers and the frequency, you should be able to determine whether the signals fit the 0045 version, the 0068 version, the 0090 version or none of them. You should look at all the learned signals for your device together when doing that. A single device won't mix versions of RECS80, so any differences in frequency or timing between learns is due to the IR learning process, not due to any differences among the correct signals. You should find one RECS80 version that is a good enough fit for all signals of the device.
For 0045,
- frequency should be between 37000 and 39000
- first timing number between 100 and 200
- second timing number between 4500 and 5500
- third timing number between 6800 and 8300
For 0068,
- frequency should be between 32300 and 34300
- first timing number between 130 and 250
- second timing number between 5100 and 6300
- third timing number between 7700 and 9500
For 0090,
- frequency should be 0
- first timing number between 0 and 40
- second timing number between 4500 and 5500
- third timing number between 6800 and 8300
You may find decodes that don't quite fit either. If it almost fits, it may be worth testing to see if it works, but it's most unlikely to work if the second timing number is above the suggested max or the third timing number is below the suggested min. For example, I found a decode with frequency 41879 and timing numbers (132,5092,7652). The three timing numbers are perfect for protocol 0045, but the frequency is quite wrong. I have no device to test with, but my guess is that it would work anyway. For protocol 0068, the third number 7652 is below the minimum of 7700 making it quite unlikely to work. I found a different device with frequency 33333 and timing (450,5770,8656). For 0068 all but the first number are perfect and I would be quite surprised if it didn't work. For 0045 the second number 5770 is too high for the max of 5500, so it's unlikely to work.
The decodes for RECS80 all report EFCs for protocol 0045. These are not correct EFCs if you select a protocol other than 0045, so it is better to use OBC numbers when creating a JP1 upgrade based on these decodes.

In both cases E is a checksum seed (0 in all known examples) and C is a checksum given by
C = Dx:4 + Dx:4:4 + Fx:4 + Fx:4:4 + Fy:4 + Fy:4:4 + E.
EFC translation: For Sejin-1, MSB. For Sejin-2, EFC translation not available.The parameter M is either 1 or 2. It distinguishes two styles of this protocol that have different purposes and very different lead-out times L. The 8-bit parameter Dx is a signed integer. If Dx > 0 then the style is Sejin-1, used for normal buttons of a remote control. If Dx < 0 then the style is Sejin-2, used for signals of an associated 2- or 3-button pointing device. E is a checksum seed, E=0 in the only known examples. The checksum formula reflects that in the UEI executor, so is presumed correct.
The protocol parameters Dx, Fx, Fy translate into device parameters in different ways corresponding to the different uses of the protocol. In Sejin-1 the device parameters are a Device Code, a SubDevice code and an OBC as is common for many protocols. Sejin-2 has two sub-styles. One corresponds to the displacement of a cursor or other pointer with device parameters (X, Y) that give the horizontal and vertical components of the displacement (and which can be positive or negative). The other signals Button Up or Button Down for any of the three buttons of the pointing device. The Misc field of the DecodeIR output displays these device parameters for the Sejin-2 signals. The relationship between these and the protocol parameters is beyond the scope of this document. The Misc field also displays an RMOBC value for Sejin-2 signals, which is an artificial OBC value that can be used as input to RemoteMaster to create the signal concerned.
The protocol parameters for Sejin-1 include a bit that marks the end frame of a repeat sequence. DecodeIR v2.37 and later check this and will report in the Misc field if the end frame is missing. This will normally be due to the key still being held when the learning process ends, so that the end frame gets omitted from the learned signal. For Sejin-2 signals that represent button operations the signal does not repeat. A single frame is sent on button down, a different frame is sent once on button up. Both frames can be detected and distinguished by DecodeIR v2.37 and later but the button up frame will not normally be present in a learned signal.
Sharp, Sharp{1} and Sharp{2}
IRP notation: {38k,264}<1,-3|1,-7>(D:5,F:8,1:2,1,-165,D:5,~F:8,2:2,1,-165)+
EFC translation: LSBA Sharp signal has two halves, either one of which is enough to fully decode the information. A significant fraction of Sharp learned signals contain just one half or have the halves separated so that DecodeIr can't process them together. When one half is seen separate from the other, DecodeIr will name the protocol Sharp{1} or Sharp{2} depending on which half is decoded. Sharp, Sharp{1} and Sharp{2} all represent the same protocol when they are correct. But only Sharp is robust. A Sharp{1} or Sharp{2} decode might be spurious.

The decode interface does not support returning negative Subdevice or OBC. So negative motions are represented by adding 64 to them. The numbers 1 to 31 represent positive motion. The numbers 32 to 63 are each 64 larger than the true negative motion, so 63 represents -1 and 32 represents -32.

EFC translation: 6-bit LSB comp, or that prepended with extra device bit.This is not a robust protocol, so spurious decodes are likely.
DecodeIR2.42 deprecates Thompson (5 bits of device, and 6 bits of function) and reports these signals as Thompson7 (4 bits of device and 7 bits of function).
Thomson includes a toggle bit so using learned signals will have operational problems. You should use KeyMoves or Upgrades based on the decoded values, rather than continue to use the learned signals.
There are two different variants of UEI protocol 004B which have different EFC numbering. The decode lists both possible EFCs so you could experiment to discover which is right for your model. But, if you are creating an upgrade (rather than just KeyMoves) it is better to use RM and use the OBC numbers from the decode (which are stable across models of JP1 remote). As of version 8.31, KM does not have support for Thomson protocol, so if you must make an upgrade in KM you need to use pid:004B. For the URC-8040 and 8060 the second decoded EFC should be right and the OBC values in KM should be wrong. For most (maybe all) other models, the first decoded EFC should be right and KM's default EFC to OBC translation should also be right.

EFC translation: LSB of 2*OBC+1These are two variants of the same Home Automation protocol. They differ in that X10.n has a distinctive start frame that carries a sequence number, the n of the protocol name, in addition to the OBC. The repeat frames, and all frames of the X10 version, only carry the OBC. The value of n runs from 0 to 15 (or some lower value) and then restarts again at 0. It is incremented on each successive keypress. A valid X10.n signal must have at least one repeat frame. If this is missing then the Misc column shows "invalid signal".
RemoteMaster has a single protocol, named X10 with PID 003F, that sends X10.n signals. This is the same as the UEI protocol with that PID. There is no control over the value of n, this is handled automatically by the remote. The newer UEI protocol, with PID 01DF, sends X10 signals.

XMP uses one burst pair to encode numbers 0 to 15, with an on duration of 210uS, and off duration of 760uS + n*136uS where n takes on values of 0 to 15. The checksum nibble is the complement of 15 plus the sum of the other 7 nibbles, mod 16
The Device code is D, the SubDevice code is S and there are two OBC values. OBC1 is the high byte of F, OBC2 is the low byte of F. The OEM code is normally 0x44 and is reported in the Misc field only if it has a different value. The XMP-1 protocol is XMP with OBC2 = 0. The OBC field in DecodeIR then shows OBC1. The XMP-2 protocol is XMP with OBC1 = 0. The OBC field in DecodeIR then shows OBC2.This protocol has a 4-bit toggle T that is 0 for the first frame and normally 8 for all repeat frames. There is, however, a variant in which a further frame with T=9 is sent after the button is released, separated from the preceding frame by the short leadout of 13.8m that is used between two half-frames rather than the long lead-out of 80.4m used at the end of all other frames. When this frame is detected then the Misc field displays "With Final Frame". For this to be shown in a learned signal, the button must be released before the learning process times out, so a short button press is needed.
These are problem decodes because JP1 remotes don't typically learn these signals accurately enough for a correct decode. NG Prontos also do a rotten job of learning these signals. Older Prontos seem to do fairly well. DecodeIR v2.40 includes algorithms that attempt to reconstruct a valid XMP signal from a corrupt learn, but it is impossible to correct all learning errors and there can be no certainty that a reconstruction is actually correct.
In a correctly learned or fully reconstructed signal there will be an "XMP", "XMP-1" or "XMP-2" decode with device, subdevice and OBC values that can be used with RemoteMaster or any similar program to regenerate a clean signal. The Misc field shows which algorithms, if any, have been applied, as a list in brackets after any decode data in this field. There are notes below on the reliability of the various algorithms. When the protocol shows as (unqualified) XMP, both OBC values are non-zero. The OBC and Hex fields show OBC1. The corresponding values for OBC2 are shown in the Misc field.
The learned signal itself will certainly not be valid if any reconstruction algorithms have been applied and it may not be so even if it has been decoded without reconstruction. The possible algorithm indicators in the Misc field are as follows:
- End (= Endpoint): The lead-out burst is missing and has been inserted. This is almost certainly correct.
- Rec (= Recovery): Look-ahead has been used to recover a missing burst from the following repeat frame. This is very likely to be correct.
- Cor (= Correction): Two bursts have been coalesced in the learning process, e.g. those for hex digits C and D, causing a C to appear as D or vice versa. The error has been identified and corrected. This is probably correct.
- Cal (= Calculated): A missing digit has been calculated from a checksum. The digit is probably correct but it may be in the wrong place. The most likely error in the reconstruction is that the two digits of the OBC are the wrong way round.
- Cal2 (= Calculated 2) Two consecutive missing zero digits have been identified, corresponding to a zero OBC. When this happens, the signal will always be shown as XMP-1. The most likely error in the reconstruction is that it should actually be XMP-2.
If a learned signal is good enough to be recognised as XMP but not good enough to be fully reconstructed, the protocol will display with a name of the form
XMP:136.218-0F0F441A0A800F00
In IR.exe you'll need to widen the Protocol column to see the whole thing. This represents intermediate data from an unsuccessful attempt to decode a XMP signal. The number in the position where the 136 is in this example represents the time scale. A number (like this example) that is near 137 is reasonable. A number much further from 137 indicates a more serious learning or decoding problem. The number in the position where the .218 is in this example (it is not part of the 136) represents the level of inconsistency in the individual hex digit decodes. A value greater than .100 means the hex digits aren't very reliable.The hex string, where the 0F0F441A0A800F00 is, is the decoded data. At least one digit is almost certainly wrong or the whole decode wouldn't be displayed in this form. With a JP1 learning remote, the most common errors are that a digit is actually missing, in which case the string will have fewer than 16 hex digits, or that two or more digits which are decoded the same are actually different, so some of them are correct and some are one value higher or lower. Although the reconstruction algorithms attempt to correct these types of errors, it is not always possible. In this example I happen to know the correct signal. One of the three F's is really an E and one of the two A's is really a 9. The correct string is 0E0F441A09800F00.
Almost all examples we've seen start with "0E0F441A0" or "060F44120". But we've also seen upgrades from UEI for "0D1F441A0" and "0C2F441A0" and "0B3F441A0". The last 4 digits of the whole 16 digit string (if they are correct) represent the Hex command needed to reproduce the signal in a JP1 upgrade or KeyMove. DecodeIR shows them as two 8-bit OBC values, as described with the IRP notation above.
