ABSTRACT:
A method and apparatus for creating a trick play video display from an MPEG-2 digital video transport stream are described. A trick play transport stream frame sequence template for each transport stream frame sequence and trick play video display mode supported by a video recorder is stored in the recorder. When the recorder receives an input transport stream frame sequence, the sequence is identified and template corresponding to that sequence and the selected trick play display mode is selected. The template is used to identify frames of the input transport stream to be appended to the trick play display transport stream frame sequence. When the trick play transport stream frame sequence is constructed the program clock reference, presentation time stamps and decoding time stamps associated with the frames are updated from information in the template.
