ABSTRACT:
A decoder device is provided which is able to output audio and video in sync without a counter synchronized with a clock reference value. The decoder device retrieves PES and PCR from TS, and decides the timing of an audio output section and a video output section, referring to PTS appended to the PES. A local counter output section counts in a predetermined count-up cycle without an adjustment control on the PCR. A PCR & local-counter list management section generates a table paring up a counter value, when the PCR is received, with the PCR. The audio & video output sections calculate a latency time of an access unit, using both a first difference, which is between a counter value, when PTS is referred to, and the counter value in the table, and of a second difference, which is between PTS of PES and the PCR in the table.
