Abstract
An encoded bitstream is processed without re-encoding so as to recombine multiple packets of each image into contiguous data of one packet for the image. Each packet is assigned a presentation time stamp, corresponding to the display order of its image in the sequence of images. In one embodiment, each intra-frame compressed image also is marked as a recovery point indicating that a decompression processor empties its buffers of data for prior groups of pictures before processing the image. A video editing or other playback application uses the converted bitstream for scrubbing and similar playback operations.
