Sony CMT-EP313 stereo remote RM-SGP5
More data on a Sony IR remote control, this one is RM-SGP5 for the EP313 stereo:
The codes are similar to the previous Sony remote measured:

except that in addition to 12 bits, some of the buttons use 15 bit while others are 20 bits:
Power button, 12 bits 
Treble + button 15 bits 
repeat button 20 bits
Also noticed that if the remote is positioned too close to the IR decoder the first long sync pulse will be shortened. I don't plan to try to decode this remote rather the idea will be to create a duplicate remote but only with a few buttons used the most like: power, volume up and down, tuner select and CD or Tape. And of course it would have some kind of timed mute.
Here are the codes:
