摘要

PURPOSE: A transport stream recording device and a method, a transport stream reproducing device and a method, and a program recording medium are provided to detect an I-picture within a transport stream to be recorded, and to record information for identifying a packet where I-picture data is stored with discontinuity information on a data recording medium, thereby quickly realizing a random access reproduction. CONSTITUTION: A recording device(10) adds a transport packet extra header to transport packets multiplexed at irregular intervals on a transport stream inputted from a set top box, and removes intervals of source packets by generating the source packets, then creates a DVR transport stream. The created DVR transport stream is recorded on a data recording medium(21). A stream interpret block(11) examines the transport packets sequentially inputted from the set top box, extracts a PCR(Program Clock Reference), and outputs the PCR to a PLL block(12).
