Dear all,

I have been going through below mentioned update.

http://web.mit.edu/xiphmont/Public/theora/demo.html

I found this line-
Timothy Terriberry estimates a simple self-training range-coding
backend could be reasonably expected to decrease bit usage overhead by
15-20%.

Is it really true? I found one implementation....
http://svn.xiph.org/trunk/ghost/libentcode/

Did anyone verified this gain? How much is the exact gain?

Regards,
hrishi
