Mpeg-2 Compatible Hierarchical Video Coders with B-frame Data Partitioning

چکیده
A new technique of spatio-temporal scalability coding is considered for video with bitrates of order of megabits per second. Both temporal and spatial resolutions are reduced for data transmitted in a base layer. The temporal resolution reduction is obtained by placing each second frame (B-frame) in the enhancement layer. The enhancement layer includes also high-frequency spatial subbands from other frames. The base layer is fully MPEG-2 compatible. Improved prediction of B-frames yields very high efficiency of the technique proposed.

Scalable MPEG video coding with improved B-frame prediction
Recently, there is a great interest in video codecs that implement the functionality of spatial scalability. Unfortunately, those MPEG-2 and MPEG-4 coders which exhibit such a functionality produce much more bits than corresponding single layer coders. This bitrate overhead can be reduced by application of spatio-temporal scalability as proposed by the authors. The base layer bitstream correspo...
متن کاملMPEG 2-Based Video Coding with Three-Layer Mixed Scalability
The paper describes a three-layer video coder based on spatiotemporal scalability and data partitioning. The base layer represents video sequences with reduced spatial and temporal resolution. Decoding of a middle layer gives full resolution images but with lower quality as compared to those obtained from the enhancement layer also. The bitrate overhead measured relative to the single layer MPE...
متن کاملMpeg Video Bitrate Control Using Coder Modeling
The problem considered is how to estimate the value of the quantizer scale factor Q that corresponds to a given number of bits B in a given frame of a sequence. The solution exploits two statistical models B(Q) of I-, Pand B-frames coded by an MPEG coder. These models B(Q) depend on some parameters related to video content. In the first model, there are very few such parameters that can to be e...
متن کاملModeling of Bitstreams Produced by Hybrid Video Coders
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. Th...
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...
