[Abstract] Ultra High Definition Blu-ray will have HDR high dynamic range and wider color gamut and depth in addition to Hi-Fi audio.
Matsuda said that in addition to providing Hi-Fi sound, Ultra HD Blu-ray will have HDR high dynamic range and a wider range of color gamut and depth on the video. In addition, since the physical optical disk carrier can bring faster data transmission levels, it may well exceed the rate of 15mbps, and 15mbps is the basic bandwidth guarantee for Netflix's 4K streaming media. In fact, a 66GB dual-layer disc will have a data transfer rate of 108mbps, and 100GB will have 128mbps. Also, Blu-ray Disc can provide 4 frames of 60 frames.
The only question now is, is the price of 4K Ultra HD Blu-ray discs acceptable to ordinary consumers?
It should be noted that this visual enhancement may be useful for home theater enthusiasts and fans, but it is barely noticeable to many ordinary users. While HEVC (H.265) encoding is a very effective form of encoding that guarantees quality, Netflix also promises to provide high frame rate and HDR content on streaming services.
In addition, even if ultra-high-definition Blu-ray discs were introduced in mid-2015, it is still unclear when they will be officially available. After all, it will take some time until the video content in the market is widely available. Will Netflix, Amazon, and other streaming media service providers have established market positions by then?
Matsuda said there will still be space for Blu-ray discs. “Ultra-HD is a closed medium and more stable at the same time. We will provide the best picture quality. And the form of streaming media may be very unstable, depending on your bandwidth and the number of people used at the same time.†Matsuda said.
