Chapter 3 presents the design and implementation of memory management of rtos for the hdtv integrated source decoder chip 第三章具體描述應用于hdtv信源解碼芯片的實時操作系統存儲管理策略的設計及實現。
In this thesis , we research and implement me memory management methods of rtos for the hdtv integrated source decoder chip 本文以hdtv信源集成解碼芯片為開發背景,研究和實現了應用于該soc芯片的實時操作系統的存儲管理策略。
This paper will give a discussion of the method of asic design and analysis the hdtv integrated source decoder with embedded risc core and a improved de - interlacing algorithm for asic design 本文討論了asic設計方法,以及嵌入式risc核在hdtv信源集成解碼器中的設計研究和面向asic設計的視頻解隔行算法優化。
When the secure system is cracked by the hacker , the enterprises must change all the source decoder which has been placed in the stb , it will cost much more than the followed scheme , smart card scheme 如果將解密模塊從解碼器中分離出來,置于安全性能極高的智能卡中,一旦系統安全受到威脅,僅通過更換相對廉價的智能卡,就會避免數字電視運營商遭受巨額經濟損失。
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。
