Patent ID: 8072549

Claim:
A repeater apparatus comprising: a receiving part for decoding video and audio signals in a predetermined format that have been encoded by a source apparatus; a transmitting part for re-encoding at least the video signal out of the decoded video and audio signals for transmission to a sink apparatus; an audio reproducing part having an audio signal processing part and an amplifier part; and a control part for controlling operations of the receiving part, the transmitting part and the audio reproducing part, and storing information into memory, the information being acquired from the sink apparatus and defining a plurality of formats that can be processed by the sink apparatus, wherein the control part newly sets a video signal format that can be processed by the repeater apparatus, the newly set video signal format being an overlap between video signal formats that can be processed by the sink apparatus and video signal formats that can be processed by the repeater apparatus; the control part sets an audio signal format that can be processed by the repeater apparatus regardless of a format acquired from the sink apparatus; the control part replaces the format defining information stored in the memory with information defining the newly set format; the audio signal decoded by the receiving part is inputted to the audio reproducing part so as to be reproduced as audio; and the video signal decoded by the receiving part is inputted to the transmitting part so as to be re-encoded and transmitted to the sink apparatus.
