windtear 追求完美

目前传统的网络电视都是基于 Real Server 和 微软的 Media Server
Quicktime 的很少看到
以前 real server 几乎是一统江湖的

传统的方式有一个缺点
带宽问题 人太多了 就完蛋了:(

gbs_v7a.exe 这玩意的优势在于把客户端也当成了服务器
也是目前教育网比较热火的BT类似的方式
(目前水木NetResources热火的还有一个GridMedia)

搜了一下
主页似乎在这里 http://personal.ie.cuhk.edu.hk/~xyzhang2/
不过只有下载 http://personal.ie.cuhk.edu.hk/~xyzhang2/dist.zip

http://219.224.166.223 提供了下载
水木清华 欧锦赛2004 版也贴了一份

两处文件存在一些区别
水木提供的那份

标题：CCTV-5
版权是：上海交通大学网络信息中心
549Kbps
384 x 288
Windows Media Audio 9
48 kbps, 44 kHz, stereo (A/V) 1-pass CBR
Windows Media Video 9
http://localhost:6789/1.asf

确保系统能对 asf 正确解码 比如安装media player 9
运行gbs_v7a.exe
会出现cmd窗口

比如我的:
