The dm642 uses a two - level cache - based architecture, level 1 cache is composed of a 16 - kbit l1p ( level 1 program cache ) and a 16 - kbit l1d ( level 1 data cache ), level 2 cache consists of 256 - kbit memory space that is shared between program and data space
同時,研究了消除欠采樣噪聲演算法,並實現其處理功能。本文提出的系統設計方案,實現了高速、穩定、靈活的視頻採集處理播放平臺,可以高速而穩定的持久運行,達到了設計的要求。Vps video program system
視頻演放系統Second, this dissertation implements separately a mpeg - 2 video decoder and a dolby ac - 3 digital audio decoder based on software mode, and gives a audio & video synchronization algorithm based on audio - clock - benchmark in mpeg - 2 system decoder, whose feasibility and practicability have been proved by experimenting. it is an all - purpose algorithm, which can perform different decoder according to mpeg - 1 or mpeg - 2 system models, and can also be used for reference to the implementation of other multiplex stream decoders
然後,論文實現了基於軟體方式的mpeg - 2標準視頻及ac - 3格式壓縮音頻的實時解碼與回放,並依據mpeg - 2系統解碼模型實現了一種基於音頻基準時鐘的mpeg解碼器的視音頻同步演算法,實驗證明該演算法可行、實用、通用性好,對符合mpeg - 1或mpeg - 2系統標準的視音頻解碼器均具適用性。On the foundation of these technologies the structural model of the system has been given finally and been realized through c + + language. the characteristic of this system is to transmit video data through ip group broadcast technical, combining present newest sound video general code and adopting rtp / rtcp on udp ; at the same time, client end carries out medium decoding and playbacks with newest directshow technology. besides, this paper studies and designs the user bandwidth detection feedback control algorithm video coding adaptability control algorithm and network pack algorithm
該系統的特點是結合目前最新的音視頻對象的通用編碼mpeg - 4 ,採用在udp協議之上的rtp rtcp ,通過ip組播技術來傳輸視頻數據;同時客戶端採用最新的directshow技術進行媒體解碼和回放;研究並設計了用戶帶寬檢測的反饋控制演算法,視頻編碼適應性控制演算法和網路打包演算法。The video phone system designed by us is mainly the real - time implement of a - v codec the implement of h. 323 protocol stack and the implement of the network communication protocol for example pppoe smtp and pop3 etc. so we not only ensure that the qos of the a - v codec ' s datum, but also develop the increment services for example e - mail system and browser etc. the paper will emphasis on the graft and realization of the internet protocols h. 263 video codec rate control algorithms for video encoder and optimization methods of the codec based on tm1300. h. 323 sip, h. 264 and psos + are also simply introduced
本文主要針對作者在實現ip可視電話系統中所從事的研究工作而展開的,將重點放在ip可視電話系統中tcp ip協議棧在psos +上的移植、網路通信協議如pppoe 、 ppp 、 smtp 、 imap 、 pop3 、 dns 、 dhcp等協議的實現、 h . 263視頻編碼及其碼率控制演算法研究、視頻編碼中基於程序結構和7m1300dsp專用指令的優化方法,同時初步介紹h . 323 、 sip 、 h . 264及嵌入式系統中的實時操作系統( rtos ) psos + 。分享友人
