Heads up, international HD mavens. A kind tipster just alerted us to one TVP HD, a channel that just started broadcasting Olympics coverage and will continue to throughout the 2008 Games. After the spectacle has concluded, it will reportedly morph into a station much like BBC HD. Currently, the channel is available via digital cable in Poland on carriers like Multimedia Polska, Aster and a few other smaller companies that provide HD receivers. We're also told that it'll launch shortly on UPC Cable, ITI's digital satellite platform N and (in trial form) via DVB-T. In somewhat related news, the European version of MTV HD just starting testing yesterday on the Hot Bird satellite, with an expected go-live date sometime in September.
