  1. A new bit rate control strategy with both global pre - allocation and local segmentation ( glas ) for low bit rate application is proposed. first, it allots bit date to every frame in advance according to possessive rate of buffer, and then distribute different quantization parameters according conctete detail. by means of this method, buffer is controlled more particularly. and the quality of decoded image is improved, the traditional video image coding method, that is to say, the intraframe coding based on dct and the interframe prediction coding based on motion compensation, is not suitable for low bit rate compression and aside from this, the encoder is too complicated

    它首先在總體上根據緩存器的佔有率給每幀預分配比特數，然後再根據具體細節給予不同的量化參數。使緩存器得到了更細致的控制，解碼圖像的質量有所改善。針對傳統的視頻圖像編碼方法，即幀內基於dct的編碼加幀間基於運動補償的預測編碼存在不適于低比特率壓縮，編碼器復雜等不足，討論了基於3 - ddct的xyz視頻圖像壓縮編碼方法，提出了3 - ddct系數的三維「 z 」形掃描方案，大大提高了編碼效率。
  2. This algorithm increases the speed and accuracy of the motion vector search in intra - frame / inter - frame model selection, i proposed an adaptive selection method of intra - frame / inter - frame prediction model, based on tmn recommendation. in this paper, chapter one introduces the needs for low bit - rate video compression and relevant standards. chapter two first introduces briefly some common image compression methods, then emphases on the algorithms used in h263 + encoding and decoding

    本論文第一章概述了當今世界對甚低碼率視頻圖象壓縮編碼的需求以及相關的國際標準；第二章簡要介紹一些具體的圖象壓縮編碼方法，對于在h . 26x編解碼器中運用到的圖象壓縮演算法給予了重點介紹；第三章詳細探討了h . 26x系列標準，對于重點和難點部分作了詳細的闡述；第四章是具體的編解碼器設計以及核心演算法描述；第五章是h . 26x編解碼器在局域網視頻傳輸中的一個具體運用。
  3. First the survey of video encoding development has been conducted, then the video compression technology has been introduced and the application of fpga and dsp processor in video compression field is appended, finally the hardware implementation of video compressor based on h. 263 standard is introduced. according to the characteristic of fpga, we bring forward the motion estimate and dct / idct arith metic which can be easily implemented in hardware

    首先介紹了視頻壓縮編碼發展的概況；然後介紹基於變換編碼的視頻壓縮方法，並介紹fpga和dsp處理器在視頻壓縮編碼器中的應用；最後介紹了基於h . 263標準的視頻壓縮編碼器硬體實現，並根據fpga的特點，提出適合其實現的運動估值演算法和dct和idct演算法。
