8.20. CEC Command Sending
DIFFERENCE:
This feature is available from firmware v1.1.0.
The device is able to send and receive Consumer Electronics Control (CEC) commands. This feature is for
remote controlling the source or sink device. CEC is a bi-directional communication via HDMI cable.
INFO:
The hidden first 2 bytes of the CEC command is static, it refers to the logical address of the sender
and the addressee. When the port is input, it is always 04 (from TV to Playback device 1.)., when the port
is output, it is always 40 (from Playback device 1. to TV). Broadcast addressing is also possible (in this
case it is 0F or 4F). #cec
8.20.1. Press&Release Commands
DIFFERENCE:
This command is available from firmware v1.3.0.
Below CEC commands are called 'push-button commands', e.g. volume up/down. When the CEC command
is sent, the 'release' command is also sent in the background. Certain devices require this feature for the
proper working, but this is necessary only for push-button commands.
