Source Coding with Causal Side Information at the Decoder
2 ⌋ }. The i-th reconstruction is of the form X̂i(T, Y ), i.e., it is allowed to depend on the side information, but only causally. The motivation for studying this problem comes from source coding systems that are constrained to operate with no, or with limited, delay. Sequential source codes with a limited-delay encoder and a sequential, zero-delay, decoder with access to side information comp...
متن کاملSuccessive 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...
متن کاملSource Coding with Decoder Side Information
In this report, we study source coding problems with decoder side information (SI). Source coding problems with decoder side information are a special case of distributed source coding problems. We outline the relation between various distributed source coding problems in Table 1 with the help of Figure 1. For reference, we also include the standard single-source lossless and lossy compression ...
متن کاملCommon Reconstructions in the Successive Refinement Problem with Receiver Side Information
We study a variant of the successive refinement problem with receiver side information where the receivers require identical reconstructions. We present general inner and outer bounds for the rate region for this variant and present a single-letter characterization of the admissible rate region for several classes of the joint distribution of the source and the side information. The characteriz...
متن کاملSide information generation in Wyner-Ziv decoder
Wyner-Ziv (WZ) encoder is a low -complexity encoder and can be made to achieve compression comparable to traditional high complexity encoders but at the expense of a high-complexity decoder. The high complexity of the decoder is mainly attributed to the generation of side information which involves motion estimation. In this paper sub-pixel motion estimation and intra-prediction based on H.264 ...
