IMDb reports: High-Definition Movies Coming to Hotel Rooms. The story says that the capability will be provided by an outfit named nSTREAMS; they presently produce all kinds of large boxes that provide multimedia entertainment to hotels, hospitals, schools, and karaoke bars. I don’t see any boxes on their website that specifically tout HD support, but they must be coming soon.
I gained a small interest in these hotel-based entertainment solutions just recently when I came across a thorough investigation of something called the Famicombox, apparently a pay-per-play NES solution installed in hotel rooms a long time ago. These systems never made it to the U.S., but there were successors at least in the N64 generation and I believe for the SNES as well. I think PlayStation might have gotten in on the hotel action as well.
There was pay-per-play NES in hotel rooms in the USA, too. I remember one hotel which had Super Mario Brothers and Contra…maybe others, I’m not sure. I think it actually worked on a pay-per-hour basis.
