高比特率電信網路用終端用戶多組電纜.第1部分:架空電Different bit rates are allocated to wavelet blocks according to energy the wavelet blocks include. bit rates in wavelet blocks are adaptively adjusted in coding process. by use of bipartition, the entropy of each wavelet block approximates to the target bit rate of one
該演算法首先根據每個小波塊所含能量的多少和到每個小波塊實際編碼所用的比特數，給其分配不同的碼率；然後根據二分法，通過調整各小波塊的量化因子使得各小波塊的熵逼近它的目標比特率。Cbr continuous bit rate, or constant bit rate
連續的比特率或不變的比特率Because of huge data quantum and high demand of channel bit error rate for video transmission, and fallibility, time variability and limited band of wires channel, wireless video system is faced with lots of problems
由於視頻業務的數據量大、對誤比特率要求高，無線通道又具有易錯、時變和帶限的特點，因此通道的誤比特率要比有線環境大得多，且隨著基站和終端位置、方向的改變而變化很大。Needless to say fixed quantizer / quality has very limited use for most of us
所以說定比特率編碼對我們的用處很小。The first facet is to put forward four - step block matching algorithm which can deduce the time of motion estimation and improve the coding efficiency, based on the traditional motion estimation algorithms. the second facet is to propose a new rate control algorithm, that is average - reaction rate control algorithm, based on the rate control of mpeg2. the new rate control algorithm can achieve rapid and efficient adaptive coding
首先在對傳統的運動估計演算法進行研究和改進的基礎上，提出了四步搜索塊匹配的運動估計演算法，減少了運動估計的時間，提高了編碼效率；其次在分析mpeg2比特率控制的基礎上，提出了一種新的比特率控制演算法? ?平均響應比特率控制演算法，該演算法能夠快速有效的實現自適應編碼。Atm adaptation layer type 2 : this aal supports class b traffic, which is connection - oriented, variable bit rate ( vbr ), isochronous traffic requiring precise timing between source and sink
Atm適配層類型2 ：這種aal類型支持b級傳輸業務，面向連接，可變比特率（ vbr ） ，在傳輸源和目的地之間需要精確定時的同步傳輸。Proposing to adaptively encode run length with 3 symbol ' s arithmetic coding in term of it ' s binary form, which can be generalize any codec using run length. hereby, bdrl is realized to form embedded bitstream
與一些流行的性能優秀的小波編碼器相比，對于文中的一些測試圖像，在各個比特率時mcgsd的效果都是最好的，峰值信噪比（ psnr ）值都是最高的。It is possible to setup integrated streams defined perfectly and can be led to pipe with constant bandwidth, if diffserv authenticates and classifies data streams of constant bit rate using the rsvp parameters or according to the types of special application
如果diffserv使用rsvp參數或根據專門應用類型對恆定比特率（ cbr ）數據流進行鑒別和分類，就可能建立完全定義的綜合流，它能夠被引導成為固定帶寬的管道。The simulation results show that the algorithm have not only cut down the average coding time, but also reduced the average coding bit rate
測試結果表明該演算法在減少平均編碼時間的同時，也降低了平均編碼比特率。The current researches include how to cut down the computation complexity, how to reduce the average coding bit rate, how to improve the quality of reconstructed image, and which algorithm to be suitable to vlsi implementation
在該技術中，減少運算復雜度、降低平均編碼比特率、提高恢復圖像的質量和便於硬體實現等方面是當前研究的主要方向。In improved uep scheme, the syntax elements belonged to luminance parts and chrominance parts was reassigned to different data partitions. those packets containing syntax elements belonged to luminance parts were got error protection at high level so as to guarantee their correctness during transmitting in error - prone network. simulation has shown that using proposed scheme, the packing tradeoff is decreased 8240 bytes in error - free channel and also the output bits and bit rate of coded video stream are decreased 2. 70kbits and 0. 33 kbps respectively
模擬實驗表明，本方案能在無噪通道中有效降低編碼器端8240位元組的打包開銷和2 . 70kbit的輸出比特數以及0 . 33kbps的比特率，而在有噪通道中可使解碼輸出重構視頻圖像的視覺質量得到一定程度的提高，亮度分量峰值信噪比可增加近1db 。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。Hdsl2 hdsl4 2 high bit rate subscriber line - 2nd generation hdsl2 hdsl4 issue 2
