Abstract:
1. A picture data reproducing apparatus which reproduces compressed picture data recorded to a recording medium according the MPEG standard, the apparatus comprising: a storage means for storing compressed picture data read from a recording medium; an STC generating means for generating, for a normal-speed reproduction, STC (STC_d) sequentially from a set initial value, wherein the STC (STC_d) is delayed a fixed time (System_delay) from STC (STC_medium) of the compressed picture data read from the recording medium; a read control means for sequentially reading compressed picture data stored in the storage means on the basis of STC_d generated by the STC generating means; and a decoding means for decoding the compressed picture data read by the read control means to generate picture data for display; the STC generating means setting, at shift from a variable-speed reproduction to normal-speed reproduction, the initial value on the basis of a result of comparison between PTS (PTS_s) of the display picture data at the shift and STC_medium at the shift−(amount of delay due to the shift (shift_delay)+System_delay).
