When talking about HDTV standards, as I know, there are quite a few
versions on the world:

Europe:        DVB
USA:           ATSC
Japan:         ISDB
China:         AVS

I wish there is no trouble in open source community against our Chinese
standard AVS, which is friendly to hardware vendor and TV operator
(very low charge for patent usage, and not to charge content
maker/publisher and TV operator).

                                                From Beijing, China
