چکیده

We propose multiple description (MD) video coders which use motion compensated predictions. Our MD video coders utilize MD transform coding and three separate prediction paths a t the encoder, to mimic the three possible scenarios at the decoder: both descriptions received or either of the single descriptions received. We provide three different algorithms to control the mismatch between the prediction loops at the encoder and decoder. The results show that when the main prediction loop is the central loop, it is important to have side prediction loops and transmit some redundancy information to control mismatch.

Multiple-description video coding using motion-compensated temporal prediction

We propose multiple description (MD) video coders which use motion-compensated predictions. Our MD video coders utilize MD transform coding and three separate prediction paths at the encoder to mimic the three possible scenarios at the decoder: both descriptions received or either of the single descriptions received. We provide three different algorithms to control the mismatch between the pred...

A drift-free motion-compensated predictive encoding technique for multiple description coding

Multiple description coding (MDC) is a source coding technique that exploits path diversity to increase the robustness of transmitting a compressed signal over error-prone channels. However, the application of MDC to video coding is still problematic because a prediction mismatch problem, called drift, may occur at the decoder when one description is lost. In this paper, we propose a drift free...

A Method to Reduce Effects of Packet Loss in Video Streaming Using Multiple Description Coding

Multiple description (MD) coding has evolved as a promising technique for promoting error resiliency of multimedia system in real-time application programs over error-prone communicational channels. Although multiple description lattice vector quantization (MDCLVQ) is an efficient method for transmitting reliable data in the context of potential error channels, this method doesn’t consider disc...

Error resilient video coding using multiple description motion compensation

A new approach for multiple description video coding using motion compensated prediction is proposed. The temporal predictor is designed to provide a desired trade-off between prediction gain and mismatch between the predictions obtained at the encoder and that at the decoder when only one description is available. The mismatch signal is explicitly coded to avoid error propagation. The system c...

Rate-constrained multihypothesis prediction for motion-compensated video compression

This article investigates linearly combined motion-compensated signals for video compression. In particular, we discuss multiple motion-compensated signals that are jointly estimated for efficient prediction and video coding. First, we extend the wide-sense stationary theory of motion-compensated prediction for the case of jointly estimated prediction signals. Our theory suggests that the gain ...
