Abstract:
Methods and apparatus for dynamic volume punch through in a home entertainment system that includes a client device that receives programming signals coupled to an audio/video amplifier, and a television coupled to the audio/video amplifier. A remote control that communicates over a radio frequency interface with the client device “punches through” volume adjustment commands from a user to either the audio/video amplifier or to the television depending on the power state of the audio/video amplifier. The remote control receives the information indicating this power state from the client device that detects the power state of the audio/video amplifier through a bidirectional bus in a cable interface, for example, HDMI-CEC bus. The volume is “punched through” to the audio/video amplifier or to the television over a second communication link, for example an infrared optical interface.
