Ultra HD 4K Blu-ray should arrive in time for Christmas

Old-school optical media will look a little sharper with the arrival of Ultra HD Blu-ray discs in time for Christmas.
The Blu-ray Disc Association says it will start licensing the 4K video format on 24 August, and anticipates “product announcements from various companies” in the fourth quarter of the year. Presumably that includes both the Blu-ray players and the Ultra HD discs on which to play them. While some Blu-ray players already offer 4K upscaling, the scaling algorithm can make images look either more jagged or blurrier than native 4K playback.
Beyond just the resolution boost to 3840×2160, the Ultra HD Blu-ray format offers an expanded colour range and framerates up to 60 frames per second. It will also support high dynamic range video, provided you have a TV and content that supports it. Ultra HD Blu-ray players will be backwards-compatible for playing 1080p Blu-ray discs as well.
Also interesting is the Blu-ray Disc Association’s plan for a digital bridge feature, which will let users create an authorised digital copy from the disc.
The specifics on digital bridge still aren’t clear, but as ExtremeTech reports, users might be able to load movies onto a hard drive and watch them while they’re connected to the Blu-ray player, eliminating the need to swap discs. Users may also be able to export a copy to other authorised devices, such as phones, tablets, and portable hard drives. (Some Blu-ray discs already include a digital copy with strict digital rights management, or allow users to stream the movie to supported apps through UltraViolet.)
So far, the establishment of Ultra HD has largely fallen to streaming services such as Netflix, Amazon, and YouTube. But streaming in this format requires a lot more bandwidth, with Netflix recommending 25Mb/s for Ultra HD versus 5Mb/s for HD. While optical discs are clearly on the decline, they’ll likely remain the best option for videophiles with limited bandwidth or data caps.
