Abstract
A bit stream which is a data string including coded data of a multiplicity of channels is output from a tuner section 22, and a recording channel selection section 23 selects coded data of a desired channel from the bit stream and output by configuring the data string. The data string output from the recording channel selection section 23 is recorded to and reproduced from a magnetic tape of a recording and reproducing section 24 by a rotary head. The coded data of the data string reproduced from the recording and reproducing section 24 is discompression-encoded by an MPEG2 decoder 25 and a video signal is output.
