System and method using a packetized encoded bitstream for parallel compression and decompression
First Claim
1. A system for parallel compression and decompression of a bitstream, comprising:
- an encoder system comprising;
a plurality of encode units operable to receive components separated from a bitstream and to encode the components using a compression algorithm;
the encode units further operable to construct packets from the encoded components, where at least one packet is associated with each encoded component and the at least one packet comprises header information and encoded data; and
a multiplexer coupled to the encode units, the multiplexer operable to combine the packets into a packetized encoded bitstream; and
a decoder system comprising;
a feeder operable to separate packets from the packetized encoded bitstream;
a plurality of decode queues, the feeder further operable to distribute the packets to the decode queues;
a plurality of decode units each associated with one of the decode queues, the decode units operable to decode packets using a decompression algorithm to recover the encoded data and to reconstruct the components; and
a pixel sync coupled to the plurality of decode units the pixel sync operable to combine the plurality of components to recover the bitstream.

Abstract
A system and method are disclosed for parallel compression and decompression of a bitstream. For compression, the bitstream is separated into a plurality of components, and the components are encoded using a compression algorithm. Packets are then constructed from the encoded components. At least one packet is associated with each encoded component and comprises header information and encoded data. The packets are combined into a packetized encoded bitstream. For decompression, the packets are separated from the packetized encoded bitstream using the header information. The packets are then decoded in parallel using a decompression algorithm to recover the encoded data. The plurality of components are reconstructed from the recovered encoded data and combined to-recover the bitstream.
