On Multistage Successive Refinement for Wyner-Ziv Source Coding with Degraded Side Informations

We provide a complete characterization of the rate-distortion region for the multistage successive refinement of the Wyner-Ziv source coding problem with degraded side informations at the decoder. Necessary and sufficient conditions for a source to be successively refinable along a distortion vector are subsequently derived. A source-channel separation theorem is provided when the descriptions ...

Robust Video Transmission over Binary Symmetric Channels with Packet Erasures

A video transmission system is presented based on the 3-D SPIHT algorithm for video compression and turbo codes for channel error protection. The channel considered is a binary symmetric channel with packet erasures, used for modeling the concatenation of a congested wired link followed by a noisy wireless hop. Unequal error protection with turbo codes is used for providing strong channel prote...

Successive refinement of information

269 Abslruct-The successive refinement of information consists of first approximating data using a few hits of information, then iteratively improving the approximation as more and more information is supplied. The goal is to achieve an optimal description at each stage. In general an ongoing description is sought which is rate-distortion optimal whenever it is interrupted. It is shown that a r...

Additive successive refinement

Rate-distortion bounds for scalable coding, and conditions under which they coincide with nonscalable bounds, have been extensively studied. These bounds have been derived for the general tree-structured refinement scheme, where reproduction at each layer is an arbitrarily complex function of all encoding indexes up to that layer. However, inmost practical applications (e.g., speech coding) “ad...

Successive Refinement of Abstract Sources

In successive refinement of information, the decoder refines its representation of the source progressively as it receives more encoded bits. The rate-distortion region of successive refinement describes the minimum rates required to attain the target distortions at each decoding stage. In this paper, we derive a parametric characterization of the rate-distortion region for successive refinemen...
