  1. 2, under equally see the quantity, compress the calculate way s exportation code plain deal connect the good and bad that decide its function of the good and bad, or say, output the code the term of same alike rate the bottom, and the portrait quantity reflected the function of the compression calculate way. adopt with dv all because of the m - jpeg an inside compress the way, efficiency of their compression certainly want lower than mpeg2. certainly, this is an average circumstance, at the time that low code rate, the mpeg2 can compare the m - jpeg compression the ratio high and a lot of but keep the good diagram to resemble the quantity ; but at request the diagram to resemble the quantity the good time for example the sow the room program edit with empress period creation, their difference to is not very big. too is to say, just at the compression efficiency that not emphasize the portrait quantity that the circumstance, mpeg2 is high

    2在同樣的視頻質量下，壓縮演算法的輸出碼率直接決定其性能的優劣，或者說，輸出碼率相同的條件下，圖象質量的優劣反映了壓縮演算法的性能。由於m - jpeg和dv都是採用幀內壓縮方式，它們的壓縮效率當然要比mpeg2低。當然，這是一個平均情況，在低碼率的時候， mpeg2可以比m - jpeg的壓縮比高很多而保持較好的圖像質量而在要求圖像質量很好的時候比如演播室節目編輯和後期製作，它們的差別不是很大。

In packet based wireless video communications, when best band distribution, not only source distortion should be considered, but also channel distortion caused by channel errors. the existing macroblock - layer rate control schemes calculates quantization parameters of all macroblocks ( mb ) in a frame in a raster scan order, and then encodes the mbs in the same order. actually, the quantization distortion is heavily dependent upon the coding order of mbs

    在基於包的無線視頻傳輸中，最佳帶寬分配時，不僅要考慮信源編碼失真，也要考慮由於通道差錯引起的通道失真；已有的宏塊層碼率控制演算法以矩陣掃描的順序計算一幀中所有宏塊的量化參數，事實上量化失真與宏塊的編碼順序有很大關系，改變宏塊的編碼順序，使復雜的宏塊分配到更多的比特數，顯然能大大提高編碼效率。

    文章最後在不同的編碼參數下，將所提演算法與兩種傳統小波域運動估計演算法作比較，根據實驗所得數據分析，發現所提演算法在性能上要優于另外幾種演算法，具體體現在運動估計后所得殘差幀能量更小，重構幀客觀與主觀質量更高。
  6. Most of these standards are based on the method of inter - frame motion compensation and two - dimensional discrete cosine transform ( 2d - dct ) and encode and describe the color video in ycbcr 4 : 2 : 0 format, which want to take advantage of human visual system ( hvs ) to save bit expense by decreasing the resolution of two color difference components

    當前國際上的壓縮標準普遍採用幀間運動補償加幀內二維離散餘弦變換的編碼方法，並且將彩色視頻序列表示為ycbcr格式，試圖利用人眼的視覺特性降低對色差信號的解析度來節省比特開銷。
  7. Fast image scaling with high fidelity plays a key role in video processing and codec by providing various resolution, reducing bitrates to facilitate video transmission and achieving the best visual quality at the receiver

    在視頻編碼轉化中，必須確保幀內編碼幀（幀）經過縮放后仍然具有很高的質量，才能使后繼運動預測幀的運動補償誤差達到最小化，從而到達較好的視頻編碼轉換效果。
  8. Motion compensated prediction error image has significant amplitudes mainly along the boundaries of moving objects, correspondingly its wavelet coefficients contain large energy in high frequency bands. this greatly reduces the coding efficiency of ezw. it is first provided that the correspondence between the significant amplitudes area of the mcp error image and the wavelet coefficient significant map, then encode the significant map efficiently using quadtree approach, followed by bit - plane coding the significant coefficients to produce an embedded data stream. experiment result shows that compared to ezw and zte, the proposed algorithm is more efficient and has better performance

    演算法對于運動補償余量誤差幀首先進行小波變換，並選取適當的閾值，用重要圖表示大於該閾值的重要系數。根據殘差幀小波系數的統計特性，用四叉樹方法編碼重要圖，並對重要系數作位面編碼，生成嵌入式碼流。實驗表明，與ezw ， zte等演算法相比較，該演算法編碼效率高，復現圖像質量好。
  9. Considering the stability and continuity of face region, and the error propagation effect due to the high error rate in wireless channels, the intra - refresh method is used. the redundant data is not too much owing to the continuity, and the error propagation effect can be stopped accordingly

    由於視頻中出現的人臉具有穩定性，連續性等特點，同時考慮到無線移動通道由於誤碼率高而引起差錯傳播問題，所以採用幀內編碼宏塊刷新的方法。
  10. One of the common characters between traditional algorithms based on dct image coding is that regardless of the content of the image, they use a fixed size block to process, for example, jpeg, mpeg - 1 / 2, h. 263 use constant 8 * 8 block mode. the main work of this article is to propose a sequence images compression algorithm that is based on adaptive block dividing and object to the disadvantages of the one based on fixed - size block dividing. the proposed algorithm is an image compression method, which can auto - adjust dct block size ( 8 * 8 or 4 * 4 ) according to the difference of corresponding blocks between two frames of the sequential image and doesn ’ t process any unnecessary data blocks in order to enhance coding efficiency

    傳統的基於dct的圖像編碼演算法的一個共同特點就是:不管圖像的具體內容，採用固定的塊尺寸進行統一的處理，例如jpeg ， mpeg - 1 / 2 ， h . 263均採用固定的8 8分塊方式，本文的重點工作是針對這些採用固定的塊尺寸進行統一處理的演算法的一些缺點，提出了一種基於自適應分塊的序列圖像壓縮演算法，該演算法是一種根據序列圖像兩幀間對應塊的差別自動調整dct變換尺寸（ 8 8或4 4 ） ，對不必要的數據塊不進行處理，以提高編碼效率的序列圖像壓縮編碼方法，具有較高的編碼效率和較好的壓縮效果，與傳統的採用8 8固定分塊方式的壓縮編碼演算法相比，性能有較大幅度的提高，在文中，作者對兩者的壓縮編碼性能進行了分析比較。
  11. The mpeg2 is divided into the portrait quantity for high code rate of a few and different compression method, i good, but the space and mjpeg is basic same alike ; ibp the code rate is small, and the space request small, but the portrait quantity is badly, and in all likelihood synthesize the empress portrait the painting to speak for itself. therefore the one mpeg2 can t satisfy to unify the request of the format. explain : ocean company will plait of many formats of new product support that release, can support the dv25, dv50, mpeg2 i, mpeg2 ibp. etc.

    8mpeg2分為幾種不同的壓縮方式， i幀高碼率的圖象質量好，但是存儲空間與mjpeg基本相同ibp幀碼率小，空間要求小，但是圖象質量很差，多半合成后圖象劣畫很明顯。所以單一mpeg2不能滿足統一格式的要求。解釋：大洋公司將推出的新產品支持多格式混編，可以支持dv25 dv50 mpeg2 i mpeg2 ibp等。
