Hi Honza

The problem with EPG data is not only how quickly the provider will
update them, but more how data will sync width video content.
Actually, I don't know any provider who send EPG data synchronized with
program at a precision less than one second. 
But, I know that some expensive and closed solutions exist to make
frame recognition in a stream. So, it could be implemented in
opensource... 
Has anyone done it? Or interested to do so ?
