希爾排序算法: 基本思想：將整個無序序列分割成若干小的子序列分別進行插入排序。 序列分割方法：將相隔某個增量h的元素構成一個子序列。在排序過程中，逐次減小這個增量，最后當h減到1時，進行一次插入排序，排序就完成。增量序列一般采用：ht=2t-1,1≤t≤[log2n]，其中n為待排序序列的長度。

This a simple database management system. It doesn t use any other code (i.e. ODBC, ADO, etc.) and has it s own database file format. I wrote it because I found the other DBMSs code too bulky and hard to debug. It s designed for small applications and I doubt it could handle anything on a large scale. A sample program included in the .zip shows how everything works. The database project is a library project, so you ll have to compile and link with the .lib file to get everything working. Pros: - You have the source code so you know exactly what it is doing - Database files are very small - Small and fast code Cons: - Can t handle large amounts of records (more than 65000ish) - Doesn t support SQL (you have to search the database by cycling through the records and testing them against your constraints) - Each database file can only have one table.

H.248協議，也叫MeGaCo協議，是媒體網關控制器（MGC）與媒體網關（MG）之間的一種媒體網關控制協議，這個協議是一項ITU-T與IETF合作結果的新標準。目前ITU-T、IETF、軟交換論壇等標準化組織正在加緊對H.248協議進行完善，各大電信設備制造商也在H.248協議的研發和應用上加大了投入。與MGCP協議相比，H.248協議可以支持更多類型的接入技術并支持終端的移動性，除此之外，H.248協議最顯著之處在于能夠支持更大規模的網絡應用，而且更便于對協議進行擴充，因而靈活性更強，已逐漸取代MGCP發展成為媒體網關控制協議的標準

H.264/AVC, the result of the collaboration between the ISO/IEC Moving Picture Experts Group and the ITU-T Video Coding Experts Group, is the latest standard for video coding. The goals of this standardization effort were enhanced compression efficiency, network friendly video representation for interactive (video telephony) and non-interactive applications (broadcast, streaming, storage, video on demand). H.264/AVC provides gains in compression efficiency of up to 50％ over a wide range of bit rates and video resolutions compared to previous standards. Compared to previous standards, the decoder complexity is about four times that of MPEG-2 and two times that of MPEG-4 Visual Simple Profile. This paper provides an overview of the new tools, features and complexity of H.264/AVC.
