H.264/AVC is the current video standardization project of the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). The main goals of this standardization effort are to develop a simple and straightforward video coding design, with enhanced compression performance, and to provide a 鈥渘etwork-friendly鈥?video representation which addresses 鈥渃onversational鈥?(video telephony) and 鈥渘on-conversational鈥?(storage, broadcast or streaming) applications.

The STi7200 is a new generation, high-definition set-top box/DVD decoder chip, and provides very high performance for low-cost HD systems. With enhanced performance over the STx7109, it includes both Windows Media Video 9 and H.264 video decoders for new, low bitrate applications. The STi7200 is able to decode two HD programs

--stdafx.h中沒有函數(shù)庫，只是定義了一些環(huán)境參數(shù)，使得編譯出來的程序能在32位的操作系統(tǒng)環(huán)境下運(yùn)行。 windows和mfc的include文件都非常大，即使有一個(gè)快速的處理程序，編譯程序也要花費(fèi)相當(dāng)長的時(shí)間來完成工作。由于每個(gè).cpp文件都包含相同的include文件，為每個(gè).cpp文件都重復(fù)處理這些文件就顯得很傻了。 為避免這種浪費(fèi)，appwizard和visualc++編譯程序一起進(jìn)行工作，如下所示： --appwizard建立了文件stdafx.h，該文件包含了所有當(dāng)前工程文件需要的mfcinclude文件。且這一文件可以隨被選擇的選項(xiàng)而變化。 --appwizard然后就建立stdafx.cpp。這個(gè)文件通常都是一樣的。 --然后appwizard就建立起工程文件，這樣第一個(gè)被編譯的文件就是stdafx.cpp。 --當(dāng)visualc++編譯stdafx.cpp文件時(shí)，它將結(jié)果保存在一個(gè)名為stdafx.pch的文件里。(擴(kuò)展名pch表示預(yù)編譯頭文件。) --當(dāng)visualc++編譯隨后的每個(gè).cpp文件時(shí)，它閱讀并使用它剛生成的.pch文件。visualc++不再分析windowsinclude文件，除非你又編輯了stdafx.cpp或stdafx.h。 在這個(gè)過程中你必須遵守以下規(guī)則： --你編寫的任何.cpp文件都必須首先包含stdafx.h。 --如果你有工程文件里的大多數(shù).cpp文件需要.h文件，順便將它們加在stdafx.h(后部)上，然后預(yù)編譯stdafx.cpp。 --由于.pch文件具有大量的符號信息，它是你的工程文件里最大的文件。 如果你的磁盤空間有限，你就希望能將這個(gè)你從沒使用過的工程文件中的.pch文件刪除。執(zhí)行程序時(shí)并不需要它們，且隨著工程文件的重新建立，它們也自動(dòng)地重新建立。
