Theres no real spec for how a broadcaster should do distribution of HD subtitling. Theres no such thing as VBI in HD, so new methods are being looked at for how to carry subtitles within the video distribution. The only channels currently doing subtitles are the ones who can encode the channels at the same place as playout occurs so don't have to distribute the subtitles to a seperate encoding site.
