I have kept it in my todo list, just now I am working on isdb closed caption, will take it over after completing isdb, if someone want to take it over, I would help him. For sure. I expect basic isdb to be completed by 10-15 days.

Also I wanted to ask if someone is intrested to buy the spec, or sponsor the spec of cc608 it would be highly appreciated,  since I have made this closed caption on basis of my knowledge gained at gsoc with ccextractor. So to take decision in case of discrepancy that would help a lot.
