source decoder 中文意思是什麼
source decoder
解釋
信源譯碼器-
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。 -
Compared with analog video decoder, digital video decoder has advantage of smaller area and higher quality, and offers better source for video processor
數字視頻解碼器給視頻處理電路提供了高質量的數字信號源，相比模擬解碼器，具有面積小、質量高的優點。 -
This is the core of the issue. in this section we designed the cells of the dac, including the decoder circuit, bandgap reference voltage circuit, current source circuit and switched circuit etc. the fourth chapter the simulations of circuit and errors of the dac are discussedi, so the simulation waveforms are plotted on the paper and we must take the error corrections and minimize ways
