ABSTRACT:
Data seperating means extracts intra-frame or intra-field encoded blocks from an intra-frame or inter-field encoded digital encoded, and inter-frame or inter-field encoded digital video signal, and a digital audio signal contained in an input bit stream. Error correction code appending means appends error correction codes to the extracted intra-encoded blocks. Recording means records the data having the error correction code appended, in special replay data recording areas predefined on the magnetic recording tape. During fast replay or slow replay, error correction is achieved even for tile replay signal with a low output level and a poor symbol rate.
