Method and apparatus for partitioning compressed digital video bitstream for decoding by multiple independent parallel decoders

摘要

It is well known that interlaced video result in flicker artifacts that are annoying and tiring for the viewer. The technology for displaying progressive video have improved over the years and is now feasible. At the same time digital video compression have also advanced with the introduction of MPEG2 standard. However digital progressive video requires a lot of processing power. A method of decoding compresses digital video of a progressive video sequences at 60 frames per second using multiple decoders operating at 30 frames per second is disclosed in this invention. This invention describes the method and apparatus by which the compress digital video bitstream can be partition into independent units that can be decoded by the multiple decoders in parallel.
