In addition to a flood of UHD TVs on the CES show floor this week, and some noteworthy announcements regarding streaming content, physical media fans also have some interesting news. “The Blu-ray Disc Association has confirmed the name of its 4K format (Ultra HD Blu-ray) and many of its capabilities,” reports Engadget, “while the Secure Content Storage Association has its own demo for Ultra HD movies you can download and transfer (almost) at will, with backing from Fox, Warner Bros., Samsung and others.” Panasonic demonstrated its prototype Ultra HD Blu-ray player (we could see discs by the end of this year). And like the BDA, SCSA says its finalized spec is “coming soon.” When it’s ready, the spec will be used by Samsung and M-Go to launch a 4K movie download service.
