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.

We’re still a bit away from Ultra HD becoming the standard for television. One of the things standing in the way is just how much bandwidth pushing that many pixels demands. SES recently demonstrated an Ultra HD transmission that uses the up and coming HEVC (High Efficiency Video Coding) standard, as opposed to the more established H.264. It’s demonstrated 4K broadcasts before, as seen above at its IBC booth last year, but those were using older codecs. The 3,840 x 2,160 image was broadcast at a data rate of 20 Mbps, roughly a 50-percent improvement in encoding efficiency over H.264-based MPEG-4. The demonstration was performed with support from SES’s partners, Harmonic and Broadcom, the latter of which provided the BCM7445-based decoding box used for pulling in the video. The tech still isn’t quite ready for prime time, but we’d say a 4K House of Cards stream is probably closer than any of us realized.

Even before this year’s CES kicked off, we knew Ultra High-Definition was going to dominate the show. Then from the first press conference to the last, 3,840 × 2,160 resolution displays were a center piece of almost every major manufacturer’s announcements. Leading up to the show, the CEA’s board decided against using “4K” to market these 8-megapixel (1080p is two megapixels) displays, instead choosing Ultra High-Definition or Ultra HD. Of course not everyone followed along, in fact Sony was first to market in the US, late last year, with its “4K Ultra HD TV.” The display is only one piece of the puzzle and plenty of questions remain, however. Like, “Where’s the content?” and “Will I have to replace all my other home theater gear?” Questions aside, Ultra HD TVs are here and more are coming, so click through for these answers and to discover the slate of new Ultra HD TVs for 2013.

All of that squabbling over H.264 may be rendered moot in the near future. The Motion Picture Experts Group (better known as MPEG) has just let us know that it was quietly drafting a new video standard while everyone was on summer vacation last month: H.265, also called High Efficiency Video Coding, promises to squeeze video sizes with double the efficiency of H.264. As you might imagine, this could lead either to a much smaller video footprint for bandwidth-starved mobile users or a hike to image quality with the same size as before. Imagine fast-loading HD streaming on 4G, or cable TV without all the excess compression, and you’ve got the idea. Ericsson Research visual technology lead Per Fröjdh anticipates H.265 coming as soon as 2013, when our smartphones and tablets are most likely to play it first. TV and other areas might have to wait, although Fröjdh is offering a consolation prize — he’s teasing a separate MPEG project that could give us glasses-free, compressed 3D video as a standard by 2014.
