作為我市整體轉換的承辦單位,珠海廣播電視臺將免費為合法報裝、按時交費的用戶贈送和安裝數字機頂盒一臺,同時,根據規定,到2007年12月31日,香洲轄區范圍內關閉模擬電視信號傳輸,所有有線電視用戶全部轉換為有線數字電視用戶。Direct broadcast satellite ( dbs ) / dth - service that transmits satellite signals directly to a home, typically through a viewer ' s receiving dish. also called dth for direct - to - home
直播衛星-通過接收者的圓盤天線,直接從衛星把信號傳送到戶的衛星服務,也稱為直接入戶電視。In pon, the transmission of downlink signal from olt to onu is not complex. usually, the information destined for onus are combined into a multiframe at olt via tdm before reaching the feeder fiber, and then broadcast to each onu via the passive optical demultiplexor. upon receiving the downlink multiframe signal, each onu takes out the part of information for itself only
在無源光網路中, olt到onu的下行信號的傳輸過程較為簡單,一般在olt將需要發送到各onu的信息採用時分復用的方式組成復幀送到饋線光纖,通過無源光分路器以廣播的方式發送到每一個onu , onu收到下行復幀信號後分別取出屬于自己的那一部分信息。By the tuner, the dvb - t signal received has been converted to the if signal, and then demodulated by the cofdm demodulation chip. in the end, the usb controller sends the ts ( transport stream ) to the pc where it is decoded by the software
接收到的dvb - t信號經調諧器進行下變頻處理后輸出中頻信號,再進行cofdm (編碼正交頻分復用)解調,得到的ts碼流信號通過usb控制器送入pc機中進行軟體解碼播放。The rule for propagating errors is : if the process which receives an exit signal, caused by an error, is not trapping exits then the process dies and sends exit signals to all its linked processes
傳播錯誤的規則是:如果一個進程接收到退出信號(可能是由於一個錯誤引起的) ,而沒有加以捕獲,這個進程失效並且發送退出信號給和它相鏈接的其他進程。Technical or production service, facility or equipment available to unilateral broadcasters on a permanent or temporary ( occasional ) basis, including rental of edit rooms, camera platform positions, venue injection points and unilateral transmission feeds
單邊轉播時可長期或臨時租賃的技術和製作設備、設施及服務,包括編輯室、攝像機平臺、場館單邊信號傳送點和單邊信號等。In order to improve the efficiency of transmission, receiving ts data packet on cpu ' s gpio port and transmitting data on cpu ' s pci port are processed in different priority. to improve the communications efficiency, we adopt the multicast to deliver the digital tv to relevant user
在軟體的具體實現上採用了vxworks的多任務編程思想,為了提高傳輸效率,對在cpu的gpio埠的ts數據包的接收任務和在cpu的pci埠的數據發送任務分為不同的優先級處理,並且為了提高通信效率,我們採用組播的方式傳輸數字電視信號到相應的用戶。At present, the domestic general solution for dvb is to transmit the tv programs from the local stations to satellites. then the signals are received by terrestrial stations with satellite ird ( integrated receive decoder ). at last, the tv programs are transmitted to end clients through cable dtv networks
當前我國數字電視廣播的實現方案,主要是通過各廣播電臺、電視臺的節目發射至通信衛星,再由地面接收站利用衛星數字電視解碼器( ird ? integratedreceivedecoder )接收衛星廣播信號,最後通過各地有線數字電視網將電視節目傳送到最終用戶。This system can store and regenerate the image signals received at the receive end, and transmit, at the rate of 2b ( 128 kbits ) and by using several transmission delays, image signals encoded at the rate of 256 - 384 kbits, so that the image can maintain the quality of a relayed sports event. this was realized on a trial basis in japan in 1995 and this country is now working on a high quality real - time system
該項方式在接收端可對收到的圖象信號進行存儲和再生,在2b ( 128kbits )的速率下,用若干個傳輸時延,可對用256 ~ 384kbits速率進行編碼的圖象信號進行傳送,使圖象在短時間內可維持到轉播體育比賽時的圖象品質。Both broadcast television and satellite stations transmit programming via a radio signal ( see how radio works for information about radio broadcasting )
廣播電視臺和衛星電視臺都是通過無線電信號發送節目(參見無線電廣播資料「無線電工作原理」 ) 。A significant amount of power is used by the broadcast transmitter to send the sync pulse
由於大量的功率被廣播發射機用來發送同步脈沖,一般將視頻信號的極性設計為在傳送同步信號降低功耗的方式。分享友人
