Basic commands to other devices
With regards to players or recorders, it is quite easy to drive players and recorders through the "User control pressed" command (0x44), that simulates remote control codes.
You can use something like (z being the logical address of the target device on the bus):
- play:
0z:44:44 - menu:
0z:44:0B - up, down, select:
0z:44:01,0z:44:02,0z:44:00
A lot of other commands are possible based on this model 0z:44:ab.
The whole list of available ab codes is available in the HDMI spec, as well as on CEC-O-MATIC.
