The services of electric power communication network have already expanded from telephone scheduling and transmitting data in low speed to digital user ' s service with high speed and great capacity, such as computer internet, wide area network and video transmission, etc. its structure has already developed from simple star topology, which is used to serve schedular center, to today ' s multicenter network to assure that the network can serve the requirement of increasing transmission of electric power information
電力通信網的業務已從調度電話、低速率遠動數據傳送擴展到高速、數字化、大容量的用戶業務,例如計算機網際網路、廣域網、視頻傳送等。電力通信網的結構也已從單一服務于調度中心的簡單星形方式發展到今天多中心的網狀網路,以保證能為日益增長的電力信息傳輸需求服務。After the introduction of pcm, a pair of fiber can transmit at the rate of 34 mbits, which is equivalent to 480 circuits. now, digital trunks have been introduced, with a port rate of 2 mbits, which is equivalent to 30 circuits
在pcm出現之後,一對光纖可傳送34mbits ,相當於480條電路;現交換機中繼設備數字中繼,每埠速率2mbits , 30條電路。So the general consensus is that 3g streaming is a prelude to the construction of dedicated mobile - tv broadcast networks, which transmit digital tv signals on entirely different frequencies to those used for voice and data
因此,人們一致認為3g流媒體揭開了專用移動電視廣播網路建設的序曲,這種網路可以傳送完全不同的頻率的數字電視信號用於音像的接收。The card is based on the flat roof of pc machine, at first, we are used of the source of program data to leave in ide care, then binary file is come by the send out card, which is transmitted the standard ' s transmission stream. according to the european the standard of dvb - c, variable transmission current velocity rate is 9. 6 - 38. 4 mbits / s
此卡基於pc機平臺,首先將節目源數據以二進制文件的格式存放在普通ide硬盤上,然後通過計算機的pci總線將二進制文件經過發送卡轉換成符合數字電視asi (異步串列介面)介面標準的平穩碼流。根據歐洲dvb - c標準,可變的傳送流速率為9 . 6 ~ 38 . 4mbit s 。The iso / mpeg - audio layer iii digital audio compression scheme is the most powerful of the three audio compression algorithms standardized in iso / mpeg dis - 111 72. even at very low bit - rate of only 64kb / s, layer iii is one of the most excellent compression tools for applications such as real - time network radio and high fidelity music. this paper describes a study on algorithm simulation of mpeg / audio compression layer iii
Mpeg / audiolayer提供了iso / mpegdis - 11172標準的三個音頻壓縮方案中最強的壓縮能力,即使工作於64kbps ,仍能保證高品質的音響效果,是需要以低碼率傳送數字高保真音頻信號的應用領域的理想工具。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。Added capability to calculate rates and find transit times for shipments on any digital wireless device in the u. s. customers can access these services from a one - or two - way text - messaging or web - enabled phones, personal digital assistants, pagers, or other common wireless devices
