Dvb / mpeg - 2 transport stream multiplexer / demultiplex takes an important role in digital video broadcasting system. it can combine several transport streams from source encoder into a single transport stream to transport channel, or demultiplex trasnsport stream into one program sorce to source decoder. its performance has a great influence on the program transmission ability of hdtv system and the decoding quality of decoder in hdtv receiver. mpeg - 2 system multiplexer signalized video, audio, host data and so on to fixed length packet type for making transport stream
Dvb mpeg - 2傳送流復用解復用是數字電視廣播系統中的重要組成部分之一，它將從信源編碼器輸出的多路節目源復用成一路傳輸流送入傳輸通道，或者從通道中包含多路節目源的一路傳輸流中解復用出一路節目送到解碼器解碼。 -
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。 -
