<p>PROBLEM TO BE SOLVED: To efficiently record an encoded stream onto a recording medium and to speedily perform random access. SOLUTION: An inputted transport stream is divided for each time unit having a prescribed length and among packets included in each time unit, the packets of a channel, to which recording is designated, are collected and recorded on the recording medium without adding any dummy packet. The data length of a time unit TU0 expressed with a value subtracting a leading address A (TU0) of the time unit TU0 from a leading address 'time unit address' of a recorded packet among respective time units TU0, TU1 and TU2 such as leading address A (TU1) of a time unit TU1, for example, is correspondently recorded on the recording medium as a time unit map.</p> |
