Patent ID: 7843514

Claim:
A signal receiver, which is connected to a signal transmitter via a transmission line, and which is compatible with DVI compliant sources, the signal receiver comprising: a receiving unit receiving a plurality of signals via the transmission line connected thereto, the transmission line, from which the receiving unit receives the plurality of signals, including: a first channel transmitting a first multiplexed signal in which a first digital video signal, a first time-axis compressed digital audio signal, and a first control signal are multiplexed, such that the receiving unit receives the first multiplexed signal; a second channel transmitting a second multiplexed signal in which a second digital video signal, a second time-axis compressed digital audio signal, and a second control signal are multiplexed, such that the receiving unit receives the second multiplexed signal; and a third channel transmitting a third multiplexed signal in which a third digital video signal, and a synchronizing signal are multiplexed, such that the receiving unit receives the third multiplexed signal; and a separation unit separating (i) the first time-axis compressed digital audio signal from the received first multiplexed signal based on the first control signal received by the receiving unit and the second control signal received by the receiving unit, and (ii) the second time-axis compressed digital audio signal from the received second multiplexed signal based on the first control signal received by the receiving unit and the second control signal received by the receiving unit.
