The system part of mpeg - 4 shall be detailed in chapter two , and the scene descriptor and the management of elementary stream is the core content of the whole standard 第二章將全面展開mpeg - 4的系統(tǒng)部分,場景描述和基本碼流的管理是其中的核心內(nèi)容。
This thesis is going to give a detailed introduction on the mpeg2 transrating system . the system analyzes the mpeg2 transport stream first , extracts the elementary stream from it , recompress the elementary stream using the close loop transrating algorithm , and packets the recompressed elementary stream to construct the output transport stream at the end 該系統(tǒng)可以對mpeg2系統(tǒng)層傳輸流進(jìn)行分析,從中提取出壓縮層的視頻基本流,并使用閉環(huán)降碼率算法對其進(jìn)行重新壓縮,然后將經(jīng)過降碼率處理后的視頻基本碼流重新打包,生成系統(tǒng)層傳輸流發(fā)送。
