Abstract
In a digital signal recording and reproducing apparatus, a signal obtained by multiplexing an audio signal on a bit rate reduction encoded video signal is delivered as a transmission signal. The transmission signal is multiplexed with a data showing its content, such as a copy number of times data and an edit number of times data. Depending on the state of reproduction at a reproducing side apparatus, which is a source side of transmission, a control data for controlling a recording side apparatus, which is a destination of transmission, is also multiplexed.
