ABSTRACT:
A transmitted signal is supplied to a transmission rate information extraction circuit, where information on the transmission rate is extracted. A recording mode setup circuit sets a recording mode based on the transmission rate and a mode designated by a user. An additional data modification circuit sets a recording rate of an additional data according to the recording mode. Then, a transmitted signal/recorded signal conversion circuit assigns a part or all of the recording rate of the additional data to a recording rate of data for normal playback to lengthen recording time of the data for normal playback. By means of this, recording efficiency increases.
