Technical regulation of program transmission link for live broadcasting 廣播實況轉播節目傳輸通路技術規范
Mpeg - 2 transport stream multiplexer takes an important role in hdtv system . 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傳送流復用器是hdtv系統的重要組成部分之一,它將多路節目傳輸流復用成一個多路節目的傳輸流。
This kind of mes applied the real - time runtime - state collection technology , numerical control ( nc ) program transmission technology , different nc systems integration technology , workshop workflow - recombination technology , and system - reconfiguration technology 在關鍵技術方面采用了運行狀態實時采集技術、數字控制程序傳輸技術、不同數控系統集成技術、車間工作流程重組技術和系統可重構技術等。
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信道,或者從信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。
The industry must be given first place to with traditional sound video frequency program transmission by the cable television medium , on the one hand realizing the economic value of industry under the new management model , the other side is accomplished his peculiar civilization function under special industrial concept and the policy support 有線電視媒體不會因新媒體的誕生而消亡,它的頑強的生命力之所在,就在于既要保持自己獨特的產品和服務風格,又不斷挖掘自己的潛力,向更新的媒體角色轉化。有線電視媒體,憑借其特有的網絡資源,應在實現其經濟價值的基礎上,實現其文化傳播功能。
In traditional dnc systems , computers are often placed near machines in order to control nc program transmission easily , but this usually result in a bad environment and inconvenience of computer using , greatness of investment , difficulty of management of nc program , etc . and also it is difficult to upgrade the dnc system 但傳統的dnc系統通常采用在設備現場配置計算機的方式,會產生投資大、 nc程序集中管理與分配困難、計算機使用環境惡劣、系統應用不便等問題,同時傳統的dnc系統也難以滿足系統功能不斷擴展的要求。
