HDR technology can better restore the real scene Why HDR will be hot? In fact, regarding the current video quality, there are five very important dimensions. I believe we will have some understanding. They are resolution, color gamut, grayscale, frame rate, and SDR, respectively. For the first four dimensions, they have basically grown sufficiently mature, and the dimension SDR standard has not been welcoming innovation for 50 years (most current television products Still stuck in the HDR standard, until the emergence of HDR ushered in a turnaround.
The appearance of HDR makes the development of video format more complete. The birth of HDR re-planned the research direction of video shooting, codec and imaging. In a strict sense, HDR is a standard and cannot be simply understood as a technical means. The most direct effect of HDR technology is the deeper black display and more details, but it can be improved to a more realistic brightness in terms of brightness. It can provide users with a more layered picture and more time to see To the details. The improvement is so obvious and HDR is a direction to be developed. This is why so many manufacturers have used HDR as a gimmick and development target this year.
The biggest feature of HDR technology is that it has a very high brightness dynamic range. The effect of high brightness is not just more dazzling sunlight, but also more eye-catching lighting. There is also a good level of control between this very high and very low brightness, which is the basic condition for implementing HDR technology. In addition to achieving HDR standards on the display, HDR decoding technology is also essential. The HDR chip source covers more color and brightness information, so the decoding chip and algorithm must be more powerful. At present, we use 10bit HDR decoding as the reference standard, and 10bit HDR decoding can output 1.07 billion colors, which will bring more powerful power to HDR decoding. HDR brings brightness dynamic range while also bringing more color, forming a stereo color space 10bit HDR decoding.
HDR TV in the end there is no use?
Currently both HDR and 4K are facing the same problem, that is, the lack of film sources, which makes it difficult for users to experience the impact of real HDR technology. However, there are many efforts for HDR film sources. Most of the top film and television production companies use 1000 nits as the standard for HDR content mastering to allow viewers to appreciate the image effects they hope to see. Currently Warner Bros., Penguin Pictures, Amazon, Netflix, Dolby, and other content providers are conducting research and development on HDR content. Warner Bros. has launched several films using HDR technology, and Netflix and Amazon are also planning to reach the end of 2016. Post more than 150 hours of HDR content. Some of the most popular TV dramas in the early stage include the Luan months pass and the promotion of the Prince's promotion is the use of HDR professional video cameras. The author believes that with the abundant sources, we will also see more HDR content, and the advantages of HDR TV will gradually show up.
HDR is so hot this year, and has become the target of many manufacturers. The advantage of HDR TV is very obvious. Similarly, HDR plays an equally important role in TV boxes. HDR video can be decoded and played. HDR TVs can also enjoy better picture quality, such as the colorfulness of high-light fireworks, the gorgeousness of urban nightscapes, and the brightness under normal brightness. Rich color levels. And even watching ordinary SDR film sources, HDR TV's picture effects brought by decoding the chip also have advantages over ordinary SDR TVs. In the future, as the film source continues to follow, HDR TV will be the trend. If TV boxes are Not supporting HDR will be out of date.
