随着处理能力和内存成本的降低、编码视频数据的网络支持多样化以及视频编码技术的进步，人们需要一种压缩视频表示的行业标准，以大幅提高编码效率并增强对网络环境的鲁棒性。与所有现有视频编码标准相比，H.264/AVC 标准旨在显着提高压缩性能。在这个项目中，我们采用了两种编码变换系数的方案，即指数哥伦布编码和上下文自适应可变长度编码（CAVLC）。其中最主要的贡献是应用于解码的解码策略，这导致性能增强，节省了内存和解码时间，这是带宽利用率的最重要因素。使用简单的之字形扫描技术获得变换系数。通信和视频行业主要参与者对H.264的共识可能为这一新标准提供主要推动力。
As the costs for both processing power and memory have reduced, network support for coded video data has diversified, and advances in video coding technology have progressed, the need has arisen for an industry standard for compressed video representation with substantially increased coding efficiency and enhanced robustness to network environments. The H.264/AVC standard aims to enable significantly improved compression performance compared to all existing video coding standards. In this project we employ two schemes of coding transform coefficients namely exponential Golomb coding & context adaptive variable length coding (CAVLC).And the major part of the contribution is the decoding strategy applied for decoding which results in performance enhancement saving the memory and decoding time which are the most important factors for bandwidth utilization. The transform coefficients are obtained using a simple zigzag scan technique. The consensus among the major players of the communications and video industry on H.264 might provide the major thrust for this new standard.
