Audio-video content e.g. audio-video signal, transmitting method for e.g. digital television, involves transmitting control to device if content format is not compatible with transmission interface for activating receiving interface

摘要

The method involves determining whether a format of audio-video content e.g. audio-video signal, to be transmitted to a recipient device (107b) e.g. digital television, is compatible with a transmission interface of a digital audio-video receiver and controller (AVRC) device (103b). An activation control e.g. infrared control, is transmitted to the recipient device if the format of the content is not compatible with the transmission interface of the receiver, for activating a receiving interface of the recipient device to receive the audio-video content. Independent claims are also included for the following: (1) a computer program product comprising a set of instructions to perform a method of transmitting audio-video content (2) a storing unit storing instructions to perform a method of transmitting audio-video content (3) a receiver device comprising a transmission interface.
