ABSTRACT:
There is provided a digital video recording/reproduction apparatus which can precisely perform a reproduction process while preventing noise generation even when a program has been recorded in overwriting fashion, such being realized by detecting a discontinuous portion in the stream at the time of reproduction. A PMT_PID or an ES_PID contained in each packet of a partial TS is recorded on a recording medium so as to take a different value each time there is a discontinuity in a stream. As a result, in a reproduction process of a recording medium which has been recorded in this manner, especially when data which has been overwritten on an already-recorded medium is to be reproduced, the discontinuous portion in the stream (i.e., the recorded portion immediately following the overwritten portion) can be easily determined. Thus, a precise reproduction process can be performed while preventing noise from being generated.
