H.264 codec IC, in the DVD reproducing arrangement and the H.264 codec

摘要

Disclosed is an H.264 codec IC including: a first interface to which a value of an STC obtained at a timing synchronous with a vertical synchronizing signal is inputted from an external part; a second interface to which the vertical synchronizing signal is inputted from the external part; a comparing circuit which compares at a timing synchronous with the inputted vertical synchronizing signal a value of a PTS included in an input data stream with the inputted value of the STC; and a decoding circuit which updates and outputs a decoded result when the result of the comparison in the comparing circuit shows that the value of the STC is equal to or larger than the value of the PTS, and also disclosed are a DVD playback apparatus that uses such an IC and an H.264 codec method.
