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(jù)緩存器的占有率給每幀預(yù)分配比特?cái)?shù)，然后再根據(jù)具體細(xì)節(jié)給予不同的量化參數(shù)。使緩存器得到了更細(xì)致的控制，解碼圖像的質(zhì)量有所改善。針對(duì)傳統(tǒng)的視頻圖像編碼方法，即幀內(nèi)基于dct的編碼加幀間基于運(yùn)動(dòng)補(bǔ)償?shù)念A(yù)測(cè)編碼存在不適于低比特率壓縮，編碼器復(fù)雜等不足，討論了基于3-ddct的xyz視頻圖像壓縮編碼方法，提出了3-ddct系數(shù)的三維“z”形掃描方案，大大提高了編碼效率。
2. It's difficult to find intraframe in a sentence. 用intraframe造句挺難的
