Wyner-Ziv video coding (WZVC) is very attractive for low power wireless video sensors. In this paper we show that how the transmission bit-rate of WZVC can be further reduced when multiple uncorrelated wireless receiving points are deployed at the decoder. This is different from classical SIMO in the sense of cross layer coding is deployed. When the wireless channel degrades, decoder is fed with an...
Distributed video coding (DVC) is defined such as a correlated video sequence is transmitted via the distributed independent encoders, and it can be decoded conditionally at the decoder. In the DVC coding, if an encoder encodes the video frame X and the side information Y is at the decoder, where the side information is computed using the adjacent frames of the X known as key frames. The side information...
Distributed video coding (DVC) promises good quality with low complexity transmitters. However, previous research on DVC mostly focusses lossless channel, i.e., parity bit stream is not influenced by channel noise or distortion. This paper considers DVC over realistic wireless channel with noise and multipath fading. Note, errors in the parity bit will severely impair the system performance. We consider...
Distributed video coding (DVC) has been featured by exploiting the video statistics, partially or totally at the decoder. Wireless sensor networks are supposed to have lesser complexity encoders at the expense of higher decoder complexity. Therefore DVC is more suitable to video transmission over wireless sensor networks compared to conventional video coding. Current research work on DVC is conducted...
