4K immersed in the mobile market: overqualified or Essential function?

"Sohu Digital News" October 28 news, with the advent of the Galaxy Note 3, 4K, originally mainly in the television market, the key words began to gradually penetrate the mobile market. For the latter, is 4K the next development trend? What benefits can it bring to the user? The technology web site, Android authority, has written about these issues: although "4K" looks like another bad marketing slogan, the 4K content is not useless, unlike vendors ' pointless propaganda at the press conference. It is an inheritance of the 1080p HD format and, through unprecedented detail, promises to change the way we watch TV, movies and other content. There is no doubt that 4K video is the future trend. But what is it? Will it be a little more than the pursuit of it? Before delving into the technology behind 4k, we need to understand why manufacturers are so keen on this standard. Yes, it all boils down to market dynamics. On the stage, innovation is one of the most important elements in the history of smartphone development. Today, manufacturers are more keen on "unconventional" pursuits than ever before, with HTC's UltraPixel cameras and BoomSound loudspeakers, Samsung's many sensors and features, Nokia's 41 million-megapixel camera, Galaxy note 3 of 4K video shots are obvious. Resolution is still the focus of attention, it is not without reason. Smart-phone screens are becoming clearer every year, and high-definition output (via HDMI or miracast) has always been a priority. But high-definition is not as fresh and exciting as it used to be. For smartphones that cost more than 4000 yuan, this is a commonplace selling point. That's why vendors want to support 4 K. Step-by-Step I also remember the first time in 2003 to experience High-definition television that kind of shock. Now, 1080p is everywhere. According to market research results, nearly 75% of Americans have a high-definition TV, and the most popular display is high-definition display. From a technical point of view, this is an exciting revolutionary trend. But the point of view of the monitor manufacturer is different. In their eyes, familiarity means boredom and can negatively affect sales. So, in order to get the public's attention again with cool new technology, TV and smartphone makers are struggling to move to higher resolutions, with the most popular goal of course being 4 K, the 3840x2160 resolution. At present, almost every TV manufacturer has launched its own 4K model, and LG recently showed a 5.5-inch mobile phone display, although not true 4K, but 2560x1440 resolution is very close. In addition, a family named Ortus TechnoloGY's Japanese manufacturer has also shown a 9.6-inch 4K display. Why 4K? First of all, 4K is twice times 1080p, which of course can make a small appeal to the sensitive market. More importantly, the television service providers are expected to adopt a wide range of 4K standards (parts of Japan has been implemented), and the popularity of 4K digital cameras to ensure that the 4K TV/monitor will eventually receive a rich amount of video content support. Although it can bring unmatched wealth of detail, a cheap display may not really show the difference between 4K. In addition, does the mobile processing chip have sufficient performance to produce high quality and not just 4K video with large capacity? That remains to be seen. 4K Advantage and disadvantage the main advantage of shooting 4K video is the ability to pay a large amount of detail content, video quality is also higher. 4K Video contains more than 8 million pixels, while 1080p video is only 2 million, a huge gap. 4K is also a great boon for video editors because of the large resolution increase. Because the resolution is increased by 4 times times, the cut does not cause a significant loss of resolution, and even if a lot of content is cut, the sharpness of the video can still reach HD. The 13 million megapixel BSI camera on Galaxy Note 3 will be able to shoot real 4K video. At the 3840x2160 resolution, it can take 4K video at the 26-35fps frame rate. The length of the video is limited to 5 minutes, but even so, the size of the video file is up to 1.5GB, and its bit rate is about 48-50mbps. While not all 4K video-capture experiences need to be the same as Note 3, it is a benefit of 4K photography to be able to capture detailed video with your phone at a critical moment. The clarity of 4K content is unmatched. If you've ever seen a 4K monitor or TV, you know it's a huge difference from 1080p. To use a word to describe, that is stunning. At the same time, it also allows zooming to not lose significant detail. Of course, if you want to work with 4K video, a sufficient PC (or High-performance mobile device) and software are essential. Clarity should be the main advantage of 4K, but it's also a price to pay. Recording 4K video can have an impact on your endurance, and the file itself can be very large. Qualcomm, the first to launch support for the 4K shooting mobile chip (骁丽 800), is still not announcing the compression and bitrate they use, but it is clear that the quality of their chips is certainly better than the red epic camera. Just as smartphones can't replace SLR, don't expect Hollywood blockbusters to be photographed with contest. Summing up no doubt, 4K is the future of development. 4K content and 4K photography have the ability to improve the multimedia experience, although it will be several years before the technology is popularized. But the popularity of 4K is only a matter of time, and in the next few years we willSee more affordable 4K cameras and smartphones. (Eskimo)
