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

Apparatus for reproducing video data 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 said video data reproduced from the record medium should begin, said apparatus comprising:

• reference time data separating means for separating said reference time data from the reproduced multiplexed data and for generating timing data based thereon;
• a video buffer for temporarily storing the video data and video time data which are reproduced from said record medium;
• a video time data extractor coupled to said video buffer for extracting the video time data from said video buffer;
• a video decoder for decoding the video data temporarily stored in said video buffer, said video buffer being connected to said video time data extractor and to said video decoder;
• and
• synchronizing control means coupled to receive and compare said generated timing data and said extracted video time data and for controlling said video decoder as a function of the comparison.
