I'm pretty sure they're producing all of this in Dharamshala, India, known to many as "Little Tibet." This is the small town at the foot of the Himalayas where the Dalai Lama and the CTA are based.
Teachings and public announcements from the Dalai Lama will also be broadcast at Tibet Online. The site offers video in multiple, DRM-free, no-charge formats. Early reports indicate the streams are accessible from various points inside Tibet, but that seems likely short-lived due to internet censorship practices of Chinese authorities. Link to the internet TV site, and here is an announcement by the prime minister, or Kalon Tripa, of the CTA. (Thanks, oxblood ruffin, and Om, who blogged about it here.)
I recently spent a month in "Little Tibet" and Tibet, PRC, working on a series of stories about how the internet is changing life for Tibetans. Radio stories will air on the NPR News program "Day to Day" this week, related reports will be released at Wired News, and I'll be joining CNN International host Kristie LuStout to share video from the trip there.
