推荐答案
此信息已经在FAQ中,但是最重要的是,目前无法通过Expression Encoder和IIS获得那种低延迟技术。
This information is already in the FAQ, but bottom line, there is currently no way to get that kind of low latency with Expression Encoder and IIS technologies.
我们在编码期间添加了几秒钟的延迟,然后在服务器级别进行缓存,可以再添加5-20秒,最后Silverlight也会缓存几秒钟延迟。
We add a few seconds of delay during the encoding, then there's caching going on at the server level that can add another 5-20 seconds and finally Silverlight also caches for another few seconds of delay.
完整的往返时间不到10秒,你需要一个昂贵而专注的ystem,很可能是双方都有。
For less than 10 seconds on a full roundtrip, you'll need an expensive and dedicated system, most probably on both sides.
