Satellite TV in Ultra HD quality is no longer just a dream: following a successful test broadcast this week, KT Skylife has unveiled a roadmap for offering 4K TV to its subscribers. The Korean provider plans to trial one channel of UHD content in the efficient H.265 (HEVC) video format next year, with a full commercial launch due in 2015. Widespread availability will depend on KT Skylife's ability to clear regulatory hurdles, CEO Jae-chul Moon says. The real challenge, however, may be finding customers with Ultra HD TVs. While prices are falling quickly, there's no guarantee that 4K sets will be commonplace in two years' time.
