Abstract
A demultiplexing/GOP head detecting section detects a PCR value, while a recording/reproduction control section records a video or audio packet in a bit stream file and records information on the number of packets every PCR value and GOP. In reproduction, a reproduction position corresponding to a shift time is judged on the basis of information on the number of packets at every PCR value and GOP. This improves the shifting and returning speeds to time shift reproduction.
