Patent ID: 8345169

Claim:
A signal receiving apparatus for connection to a signal transmitting apparatus via a transmission line, the signal receiving apparatus comprising: a receiver that receives (i) a multiplexed signal that an audio signal that has been time-axis compressed is multiplexed in a blank period of a video signal, via a first channel from the signal transmitting apparatus, and (ii) a control signal from the signal transmitting apparatus; a separator that separates the audio signal from the multiplexed signal based on the control signal; a time-axis decompressor that receives the audio signal that has been time-axis compressed, which is sampled by a video clock, and transforms the audio signal that has been time-axis compressed into an audio signal that has been time-axis decompressed; and an audio clock reproduction unit that reproduces an audio clock on the basis of the video clock transmitted from the signal transmitting apparatus via a second channel that differs from the first channel, wherein the audio signal that has been time-axis decompressed is sampled by the audio clock.
