Modeling of Bitstreams Produced by Hybrid Video Coders
نویسندگان
چکیده
The paper describes a simple global model of MPEG-2 video coders. This global model is defined as a relation between the bitrate and the quantization parameter for individual I-, Pand B-frames. The model has five parameters that depend on image content. Nevertheless it is shown that four of them can be fixed in order to obtain simply one-parameter model which can be used for encoder control. The experimental results are reported for some video test sequences in the BT.601/4CIF format encoded by an MPEG-2 MP@ML coder.

Fine granularity in multi-loop hybrid coders with multi-layer scalability
The paper describes a generic multi-loop coder structure suitable for mixed spatial and temporal scalability combined with fine granular SNR scalability. The structure is suitable for various variants of hybrid video coders like MPEG-2, H.263 and H.26L. The idea of mixed spatial and temporal scalability i.e. spatiotemporal scalability is substantial for the proposal. Its application allows impr...
متن کاملSimple global model of an MPEG-2 bitstream
The paper describes a simple empirical model of bitstreams produced by MPEG-2 video coders. The number of bits that represent an Ior P-frame is expressed as a function of the quantization factor Q. This model is global in the sense that it describes the total number of bits in a frame thus ignoring local bitrate variation within a frame as well as changes of Q within a frame. This fiveparameter...
متن کاملPacket Loss Protection of Scalable Video Bitstreams Using Forward Error Correction and Feedback
We propose a system for packet loss protection of quality scalable video coders. The compressed bitstream is composed of a non-scalable base layer and an embedded enhancement layer as in MPEG4-Fine Granularity Scalability (FGS) and the emerging H26L-FGS. But the system can also be used with embedded video bitstreams like the 3DSPIHT bitstream. Our system allocates a given transmission bitrate b...
متن کاملA Hybrid Coding Scheme for Videophone Images Based on Wireframe Modeling and Subband Coding
The paper presents a hybrid coding scheme suitable for coding of facial (videophone) image sequences at bit rates around 10 Kbits/s. The human head and shoulder part are parameterized by a wireframe model called Candide. The synthesized images are produced by a set of 18 parameters. Although the synthetic images generated by this model have subjectively better image quality than, for instance, ...
متن کامل. Soft source decoding with applications
Motivated by recent results in joint source-channel coding and decoding, we consider the problem of decoding of variable-length codes using soft channel values. We present results of decoding of selected codes using the maximum a posteriori (MAP) decoder and the sequential decoder, and show the performance gains over decoding using hard decisions alone. The objective behind this work is to prov...
