The video can be encoded under the HEVC high efficiency video coding standard and uses a 10-bit color depth and a Rec.2020 color gamut. As for the disc part, it supports digital bridge technology, allowing you to copy the contents of Ultra High Definition Blu-ray Disc to external storage devices, even mobile phones or tablet computers.
It is worth noting that Ultra HD Blu-ray players are compatible with previous Blu-ray discs.
Ultra High Definition Blu-ray Disc
First of all, an ultra high definition Blu-ray player must be available to play Ultra High Definition Blu-ray Disc. There are three kinds of specifications of the optical disc: 50GB, 82Mbps; 66GB, 108Mbps; 100GB, 128Mbps. They correspond to single-layer, double-layer, and three-layer films, respectively.
Ultra HD Blu-ray Disc focuses on 4K video content, but it also supports 3D content. However, even new discs only support 1080p HD 3D movies, and there is currently no plan for Ultra HD 3D movies.
Audio, Dolby Surround and DTS:X are of course important, but older audio formats on old Blu-ray discs are also supported.
Although many online streaming service providers have started to launch their own 4K content, CD playback still has its irreplaceable advantages. Ron Martin, vice president of the Panasonic Hollywood Lab, said: "The disc format is the only reliable, repeatable solution. Streaming media has its advantages, but there are many deficiencies."
It has been confirmed that the first Ultra High Definition Blu-ray Disc will be "Ace Agent: Special Vocational College".
Ultra High Definition Blu-ray Player
Samsung chose to disclose "the world's first ultra-high-definition Blu-ray player" at the IFA exhibition and grabbed Panasonic's "first". After all, the latter's products were only conceptual machines when they were released. However, Samsung’s Ultra HD Blu-ray player will be available in early 2016, which is later than the DMR-UBZ1, which Panasonic will release on November 13.
The Panasonic DMR-UBZ1 is a medium-sized CD player that is more stylish than the stylish Samsung. Interestingly, the latter built a 3TB hard drive. Both devices support 4K network content and are compatible with high-resolution audio files.
As already mentioned, Ultra High Definition Blu-ray players can be backwards compatible with existing Blu-ray discs, but not the other way around. Samsung’s player has an up-scaling technology that allows you to get as close to a 4K quality experience as possible when playing a 1080p Blu-ray disc.
The digital bridge technology that allows you to export the contents of Ultra HD Blu-ray discs is not mandatory, but we can foresee that the vast majority of players in the future will support it. After all, distressed consumers are not few.
As for the required display equipment, 4K TV is certainly the best. Your 4K TV does not need to support HEVC encoding. The player automatically recognizes the TV's specifications and makes corresponding reductions. However, if you want the best experience, you better have a TV that supports displaying HDR content.
Can we afford it?
There is no doubt that 4K is definitely much better than 1080p. The question is: Can we afford it?
Ron Martin stated that the price of Ultra HD Blu-ray discs should be similar to that of existing Blu-ray discs. The player is a little difficult to say here, Samsung has not disclosed the price of its own player, and Matsushita's products have rumors that up to 400,000 yen, equivalent to 21280 yuan. This figure has not been officially confirmed, but it also has reference value, especially when Panasonic revealed that its planned monthly shipments are not high.
Earlier this year, Ron Martin predicted that the price of ultra-high definition Blu-ray players will be two to three times that of existing high-definition players. In this case, if the Panasonic DMR-UBZ1 is based on high-end positioning, then the above rumors are not exaggerated. Of course, over time, the price of these players will surely gradually decline.
