Carrying on from part 1 we move on from codes converted from the old Pronto HEX format to learned codes
Initally these seem to have only a passing resemblence to the ECF codes converted from Pronto HEX. There are some bytes at the beginning that are the same but then after that not so much, and they are much, much longer
Here's a learned code for a Sony TV mute command, which is the same command that we had the Pronto HEX for

... and on and on for many, many lines
There is an apparent repetition of 4004 every 10 bytes, which differs from the 6 byte burst pairs seen previously. Other things we know are
- Philips like to pack numbers as small as possible
- We know the unit they use for measuring time, and it seems likely they would use it again
- The period, if it were to appear should be a number near 0x04da
- Sony codes use groups of 24 or 48 pairs, so we might see a pattern of these or numbers near 0x7470 or 0xe8e0 as before
- From the massive length of the learned code it seems likely it represents individual on/off timings rather than on/off of a carrier frequency
Reformatting gives

There are 2 instances of numbers near 0x04da in each line. Assuming these are stored in 2.5 bytes and re-formatting

There are columns that consistently contain 4 or 8, so
FFFF 2008 0100 0008 80AA
4 00438 8 09E 4 00440 8 09E

4 00445 8 095 4 0044B 8 094
4 0044C 8 097 4 00447 8 09A
....
Continuing in this style we find
4 0045D 8 086 4 07947 8 095
Where 0x07947 is approximately 25 times 0x04da. This is one more than the 24 we expected, however if we assume that this and other values preceeded with a control value of 4 are off times (which would be consistent with previous findings) then the value preceeded with control values of 8 must be the on times and those values are quite small. It seems then that the IR LED only lights up briefly during each period and spends most of the period in an off state. That would mean the final off state when the carrier is enabled would merge with the 24 units of off time equalling about 25. Also, it makes more sense that the first recorded action would be an on, not an off so the final word in the header is not actually part of the header. Correcting this and including more data

So the code is 0010100 10000. There is more data after this, but it's just a repeat of what we've seen. Sony codes don't have distinct initial and repeat bursts.
Taking the information gleaned from raw learn codes and assuming the format should be somewhat consistent we modify our previous attempt at a definition
- The header is only 3 words long
- Most everything after that is a command stream rather than purst pairs. Commands consist of a half byte control value followed by a variable length (but same for same control value) time period
- Finally there is an optional byte to define the repeat burst offset
Rearranging the data resulting from a Pronto HEX code to fit this gives
ffff 006c 0100 0008
0 a04da
6 07470 4 07460
6 07470 4 07460
6 1d1c0 4 0747a
6 07470 4 07460
6 07470 4 07460
6 0e8e0 4 0748a
6 07470 4 07460
6 0e8e0 4 0748a
6 07470 4 07460
6 07470 4 07460
6 0e8e0 4 0748a
6 07470 4 07460
6 07470 4 07460
6 07470 4 07460
6 07470 5 05000
4 00016 c 30000
0f
So the format spec now looks like
| Field | Width | Example | Description |
|---|---|---|---|
| Type | Word | ffff | ffff = Learned code, eecf = Database code |
| Length | Word | 006c | Count of bytes in ECF |
| Unknown | 4 bytes | 0100 0008 | Presumably more than one field, but not known how many |
| Command stream | Variable | See below | |
| Repeat offset | Byte | 0f | Number of bytes from beginning of command stream at which the repeat burst starts |
Where the command stream consists of multiple commands defined as
| Field | Width |
|---|---|
| Type | 4 bits |
| Duration | 12 or 20 bits |
Where command types are
| Command type | Meaning | Duration width | Example | Description |
|---|---|---|---|---|
| 0 | Set carrier period | 2.5 bytes | 0 a04da | When carrier is on the period will be defined by the last 2 bytes of the duration. The purpose of the leading "a" in the duration is unknown, could the command type actually be 0a? |
| 4 | Off | 2.5 bytes | 4 07460 | Turn the IR LED off for the specified duration |
| 5 | End sequence | 2.5 bytes | 5 05000 | Ends a burst sequence and also turns off LED for duration |
| 6 | Carrier on | 2.5 bytes | 6 07470 | Enable modulation at the previously specified carrier frequency for the duration |
| 8 | On | 1.5 bytes | 8 03D | Turn the IR LED on for the specified duration |
| c | Stop | 2.5 bytes | c 30000 | This is the final command in the stream. Purpose of duration not known. May not be present in learned codes |
- All times in units of 0.2 microseconds (1/50000000 s)
