An original blanking period of a video signal is shortened to a set blanking period, and audio data is multiplexed into a resulting superimposing period. Table distinguishing data indicating length of the superimposing period is inserted into the period as a blanking signal. With this configuration, it is possible to enable transmission and reception of an audio signal in a system capable of transmitting and receiving a video signal.
