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。It reframes the traceback problem as a polynomial reconstruction problem, and uses techniques from algebraic coding theory to provide robust methods of transmission and restriction. the scheme is a new solution to the traceback problem during a dos attack ; the honeypot for ddos, which is a tool of traceback, lures the attacker to believe that he successfully compromised a slave for his needs, convincingly simulating the architecture of a potential ddos attack ; the source - based approach to ddos defense, which is a useful adjunt to traceback systems, deploys a ddos defense system at source - end networks. attacks are detected by monitoring two - way traffic flows, and the attacks originating from source networks are stopped by rate - limiting ; the routing mechanism based on pushback treats ddos attacks as a congestion - control problem
最後,就有關ddos攻擊反向追蹤問題,從四個方面對其解決方案進行了研究:在分析比較幾種反向追蹤演算法的基礎上,著重研究了代數方法編碼反向追蹤信息的方案,該方案把追蹤重構問題當作多項式重構問題,使用代數編碼理論技術提供魯棒的傳送和重構方法,是dos攻擊過程中的反向追蹤問題的一種新的解決方法; ddos陷阱作為反向追蹤的工具,引誘攻擊者相信自己成功與所需的傀儡主機通話,令人信服地模擬出潛在ddos攻擊體系結構;基於源的ddos防禦方法作為反向追蹤有用的補充,將防禦系統部署在源網路,通過監控雙向流量檢測攻擊和限制速率終止來自源的攻擊;基於向後倒推的防禦ddos的路由機制把ddos攻擊看作擁塞控制問題,添加功能到每個路由器來檢測並優先丟棄可能屬于攻擊的包,通過向後倒推上級路由器也得到通知而把這樣的包丟棄。On designing of the encoder, by using the decoding for video chip saa7113 made in philips, analog video signal inputted realizes a / d conversion in analog / power block
編碼器的設計中,模擬/電源塊主要實現的功能是對輸入的模擬視頻信號進行a / d轉換,解碼晶元採用philips公司saa7113 。It adapts to the cdma system and achieves multi - rate speech coding and decoding. source and mode control are combines in smv for rate selection, so it improves the flexibility of cdma system, it will allow cdma subscribers to enjoy superior quality while allowing service providers to increase capacity as needed. smv is regarded as a breakthrough technology that provides significant capacity and quality gains on cdma systems, so the researching of smv is of great practical value
可選模式聲碼器( smv ? selectablemodevocoder )是3gpp2最新的用於寬帶擴頻cdma通信系統的變速率語音編碼標準,它實現了語音的多種低速編碼和解碼,在速率選擇上將源控和模式控制相結合,提高了cdma系統的靈活性,可以在保證高質量語音的同時盡可能增加系統的容量,被認為是變速率語音編碼在cdma系統中應用的「突破性」技術,代表了當前語音編碼發展的方向和潮流,因此smv的研究具有很大的價值。分享友人
