Abstract:
1. A signal transmitting apparatus for connection to a signal receiving apparatus via a transmission line, the signal transmitting apparatus comprising: a time-axis compressor that time-axis compresses an audio signal, which is sampled by a video clock; a multiplexer that multiplexes the audio signal that has been time-axis compressed into a blank period of a video signal to generate a multiplexed signal; and a transmitter that transmits (i) the multiplexed signal, via a first channel, to the signal receiving apparatus, and (ii) a control signal including information related to the video signal to the signal receiving apparatus, wherein the signal transmitting apparatus transmits the video clock to the signal receiving apparatus via a second channel that differs from the first channel to be used by the signal receiving apparatus to reproduce an audio clock for sampling the audio signal.
