A method is described for a home entertainment system ( 500 ) to control the playout of audio-visual (AV) content ( 506 ) from a source component ( 502 ) (such as a VCR or DVD player), depending on a signal ( 508 ) which indicates whether the AV content is being consumed by a destination component ( 504 ) (such as a TV or audio amplifier). The method operates without requiring any dedicated user interaction. Optionally, an apparatus ( 510 ) may interpret the signal ( 508 ) and in response generate commands ( 512 ) suitable for controlling the source component, for example by emulating infrared remote control commands. Preferably, the signal ( 502 ) and commands ( 512 ) are implemented using the Project50 protocol. |
