چکیده

This paper presents a new Base Layer coding scheme which introduces the rate-distortion optimization mode decision into hierarchical-fashion B-picture coding with open-loop structure. It can not only achieve high coding performance for Base Layer bit-rate point and meanwhile, but the scheme also keep the strong correlation between Base Layer and Enhancement Layer implemented by 3D subband scalable video codec, because they share the similar lifting based Motion-Compensated Temporal Filtering (MCTF) decomposition structure. In addition, how to exploit the correlation between Base Layer and Enhancement Layer is also investigated. Experimental results show this method improves the coding performance and visual quality at both low and high bit-rate points.

Architectures of Incorporating Mpeg-4 Avc into Three-dimensional Subband Video Coding

3D subband video coding provides an elegant fulldimensional solution for scalable video coding. However, due to the Motion-Compensated Temporal Filtering (MCTF) with open-loop structure and no good rate distortion optimization trade-off between the texture coding and overhead coding of the corresponding mode and motion vectors within narrow bandwidth, its performance is unsatisfactory at low bi...

Low complexity bit-plane entropy coding for 3-D DWT based video compression

This paper is dedicated to entropy coding for scalable video compression based on three-dimensional discrete wavelet transform (3-D DWT). A new simple bit-plane entropy coding of wavelet subband matrices is proposed. Practical results show that 3-D DWT video codec with proposed entropy coding allows to increase the encoding speed 2-3 times for the same quality level in comparison with x.264 cod...

Scalable Video Coding

With the evolution of Internet to heterogeneous networks both in terms of processing power and network bandwidth, different users demand the different versions of the same content. This has given birth to the scalable era of video content where a single bitstream contains multiple versions of the same video content which can be different in terms of resolutions, frame rates or quality. Several ...

Joint Video Team (jvt) of Iso/iec Mpeg & Itu-t Vceg (iso/iec Jtc1/sc29/wg11 and Itu-t Sg16 Q.6)

This document contains a description of an SNR-scalable extension of H.264/AVC [1]. To achieve an efficient SNR-scalable bitstream representation of a video sequence, the temporal dependency between pictures is coded using an open-loop subband approach. In this codec, most components of H.264/AVC are used as specified in the standard while only a few have been adjusted to the subband coding str...

Scalable Video Coding Based on Three-Dimensional Discrete Pseudo Cosine Transform

One of the top tasks for video streaming, video surveillance, video conferencing and video broadcasting is a low bit rate and real-time video coding. The most popular low bit rate video compression approach is based on the H.264/AVC standard [1]. This standard provides high compression efficiency due to hybrid video coding which includes intra-frame prediction, variable-size block motion estima...
