Method and apparatus for compressed video segment cut-and-concatenation for editing

摘要

A method and apparatus for compressed video segment cut and concatenation for editing uses a re-encoder (9), controller (11), ancillary storage (15), and a single decoder (13). Video segments from video clips stored on a server are chosen for playback in a specific order. References to the frames of the chosen sequence are stored by use of index pointers in ancillary storage and P or B frames near the cut points between segments are re-encoded to I frames for future insertion and re-ordered in storage for forward or reverse playback of the selected sequence by a single decoder. <IMAGE>
