Apparatus for reproducing and decoding multiplexed data from a record medium with means for controlling data decoding as a function of synchronization errors

摘要

Video data is reproduced from a record medium on which is recorded, in multiplexed form, the video data, reference time data representing a reference time, and video time data representing the time at which decoding of the video data reproduced from the record medium should begin. The reference time data is separated (5A) from the reproduced multiplexed data and used to generate timing data. The video data and video time data are temporarily stored in a video buffer (6A) and a video time data extractor (30) is connected to an output of the video buffer to extract the video time data from the contents of the video buffer. The video buffer (6A) also is connected to a video decoder (7) which decodes the video data temporarily stored in the video buffer, the operation of the video decoder being controlled (31) as a function of a comparison between the generated timing data and the extracted video time data.
