The Blu-ray Disc Association has yet to officially announce the arrival of 4K Blu-ray discs, but a manufacturer has revealed they are already being made. In the same week that the BDA told TechRadar that an announcement on 4K Blu-ray was imminent, disc creator Singulus has revealed on its website that it is one company that is “provides the machine technology for three-layer Blu-ray Discs with a storage volume of about 100GB.” This confirms that we won’t be looking at another format war when it comes to bringing 4K content to the home. 100GB is capacious enough to house a 4K movie, the only question that remains is whether current Blu-ray players will be able to play the discs, presumably with some sort of firmware update to read and playback the content. And then there is the problem of encoding. According to HDTVtest, the current H.264/AVC format may well work with discs of this size, but it is more than likely that the H.265/HEVC codec will be used as some 4K televisions at the moment do house these decoders.
