In a recording/reproducing system RRS1, an I-picture detecting section 15 generates, from a transport stream DETS output from a descrambler 13, a control signal CS indicating a bit location of a TS packet including a part of an I picture for output. Based on the control signal CS, a TS header processing section 16 specifies a TS header added to a payload of an I picture from the transport stream TS, and changes a value of a reserved bit in the TS header from 0 to 1. In high-speed replay, a storage unit SU1 refers to the reserved bit of the TS header to select only an I-picture transport packet required for high-speed replay, and composes a transport stream PRTS for transmission to a decode unit DU1. Thus, high-speed replay can be easily achieved.
