Abstract

An apparatus and method for processing a multimedia digital bitstream is disclosed. The apparatus comprises a processing chain made up of a plurality of media processors. Each media processor processes a portion of the multimedia digital bitstream in real time. Each portion of the multimedia digital bitstream is split into a primary bitstream and a secondary bitstream. The primary bitstream is processed and merged with the unprocessed secondary bitstream. The parallel processing method of the present invention enables the processing chain to output a fully processed bitstream in real time. The processing chain may be used to transcode a high definition (HD) video bitstream in real time using a plurality of bitrate transcoder units.

Description

technical field [0001] The present invention generally relates to a system and method for processing multimedia signals, and specifically relates to a device and method for parallel processing of multimedia signals. A preferred embodiment of the present invention includes an effective bit rate transcoder for high definition (HD) television signals. Background technique [0002] The development of high-quality multimedia devices such as set-top boxes, high-end TVs, digital TVs, personalized TVs, storage products, personal digital assistants (PDAs), wireless Internet devices, etc. has brought a variety of structural formats and made these devices responsive to new technologies. more open. The development of these new products and their ability to display video signals in any format has brought new requirements and opportunities for video enhancement algorithms related to video processing. Most of these devices receive and / or store video signals in MPEG-2 format. [0003] Ne...
