[Streaming Mpeg4] H.264MPEG-4AVCRealTimeImplementationonDSP DL : 0: H.264/MPEG-4 AVC is the latest generation standard from the ITU-T and ISO/IEC MPEG standardization bodies and it builds on the success of the previous ITU-T and MPEG standards. H.264/MPEG-4 AVC offers major advantages compared with previous standards, among them its high compression efficiency, although it demands a high degree of computational complexity to be able to make use of the advantages of its new techniques. In this paper several implementation issues of the H.264/MPEG-4 AVC standard have been reviewed, dealing with some of the real time challenges that appear on this kind of implementation. This implementation is to be executed on a general purpose DSP conforming with the requirements of the broadcast environments and should provide very important advantages over an MPEG-2 Encoder system.

[Multimedia Develop] h264_cabac DL : 0: The Joint Video Team (JVT) of ISO/IEC MPEG and ITU-T VCEG are finalising a new standard for the coding (compression) of natural video images. The new standard [1] will be known as H.264 and also MPEG-4 Part 10, “Advanced Video Coding”. The standard specifies two types of entropy coding: Context-based Adaptive Binary Arithmetic Coding (CABAC) and Variable-Length Coding (VLC). This document provides a short introduction to CABAC. Familiarity with the concept of Arithmetic Coding is assumed (see chapter 8 of [2] for an introduction to Arithmetic Coding).-The Joint Video Team (JVT) of ISO/IEC MPEG and the ITU-T JTC 1 are Finalizing a new standard for the coding (compression) of natural video images.

[Program doc] Videocodingwithh.264 DL : 0: H.264/AVC, the result of the collaboration between the ISO/IEC Moving Picture Experts Group and the ITU-T Video Coding Experts Group, is the latest standard for video coding. The goals of this standardization effort were enhanced compression efficiency, network friendly video representation for interactive (video telephony) and non-interactive applications (broadcast, streaming, storage, video on demand). H.264/AVC provides gains in compression efficiency of up to 50％ over a wide range of bit rates and video resolutions compared to previous standards. Compared to previous standards, the decoder complexity is about four times that of MPEG-2 and two times that of MPEG-4 Visual Simple Profile. This paper provides an overview of the new tools, features and complexity of H.264/AVC.-H.264/AVC, the result of the collaboration between the ISO/IECMoving Picture Experts Group and the ITU-T Video CodingExperts Group, is the latest standard for video coding.
