Distributed joint source-channel coding of video using raptor codes
(United States. Patent and Trademark Office, 2012-11-20)
A video encoder system includes a base layer and an enhancement layer for encoding video data. The base layer encodes a reduced quality version of the video data to obtain base layer data. The enhancement layer encodes the ...
Wyner-Ziv coding based on TCQ and LDPC codes
(United States. Patent and Trademark Office, 2012-06-26)
An encoder employs a trellis coded quantization (TCQ) unit and a compression unit. The TCQ uses a set of polynomials that have been selected to maximize granular gain. The TCQ unit operates on a block of samples from a ...
Source-channel approach to channel coding with side information
(United States. Patent and Trademark Office, 2012-08-14)
Code designs for channel coding with side information (CCSI) based on combined source-channel coding are disclosed. These code designs combine trellis-coded quantization (TCQ) with irregular repeat accumulate (IRA) codes. ...
