NetTalk是一個適用于局域網和因特網的可視電話軟件 一.開發環境 Windows2000 Server & Visual C++6.0 & SDK +自開發的CWndX類庫(相當于簡化的MFC涉及窗口的部分) 二.支持環境 Windows98/ME/2000/XP 三.所涉及協議和標準 網絡傳輸采用UDP協議,音頻壓縮采用G.729標準,視頻壓縮采用H.263標準 四.性能參數 以音頻幀為基準,每幀音頻數據有240個采樣點,時間為240*1000/8000=30ms,8000為音頻的采樣率。 數據接收端隊列緩沖延遲:30*3=90ms 數據發送端錄音延遲:30ms 數據壓縮解壓耗時:<40ms 網絡延遲:<100ms(我想校網情況應該不錯J) 總延遲:<260ms 根據VOIP標準,總延遲<300ms是人可以接受的,以上計算是保守的,實際情況可能會好得多。

cut.c 給定一塊寬度為W的矩形板,矩形板的高度不受限制。現需要從板上分別切割出n個高度為hi,寬度為wi的矩形零件。切割的規則是零件的高度方向與矩形板的高度方向保持一致。問如何切割使得所使用的矩形板的高度h最小?

OpenSVM was developped under Visual C++ 6.0 SP6, You can open the workspace file(*.dsw) in the opensvm-src folder. The folder include the svm.h and svm.cpp which in the libsvm (Copyright (c) 2000-2007 Chih-Chung Chang and Chih-Jen Lin All rights reserved) in the opensvm-src\libsvm. However, the files svm.h and svm.cpp codes were copied/merged into stdafx.h and stdafx.cpp in order to support the development, and OpenSVM still use other codes of libsvm. So you can see the libsvm package in the source package. You can open and build it with Visual C++ 6.0. Note: the problems must be in LIBSVM format.
