Abstract
Data decoding suitable for a compressed moving picture, audio information, and so forth recorded on a disc or the like. A pack header and a packet header are separated from information reproduced with the video signal; and a time code is extracted from the header of a GOP (Group of Pictures). Successive time codes are added to those pictures (B pictures and P pictures) of the GOP to which time codes have not been assigned.
Claims5
Data decoding apparatus for decoding a data bit stream which includes picture data bits representing pictures and into which time codes have been intermittently inserted and assigned to predetermined pictures, comprising:
- an extractor for extracting said inserted time codes from said data bit stream;
- an interpolator responsive to said extracted time codes for interpolating successive time codes for those pictures in said data bit stream to which time codes have not been assigned;
- an input device for inputting a time code to said interpolator;
- a detector for detecting a time difference between said inputted time code and said successive time codes;
- and
- means for displaying said successive time codes and said time difference.
