Why is 4K Ultra HD so hard?

With the development of technology, people's requirements for visual perception are getting higher and higher, not only beautiful, clarity is also a hot issue. This issue has become more and more important in the security industry. Recently, in an interview with HC Security, Blue Star highlighted the difficulties of 4K technology.

Difficulty: Technology is not mature + cost is too high

"4K's development difficulties are actually caused by the lack of mature technology and high costs." The blue interstellar Jiao Chengping couldn't help but sigh. 4K means more clarity, and it also means that video files are larger. This is too fast for the current fast-track demand. If it is universally popular, then it will face a large-scale network transformation and the cost will be a problem.

Come back to the current H. 264 compression technology is not enough to complete the 4K video compression, we can only hope for H. The popularity of 265 technology, but H. The 265 requires more computing devices and adds intangible costs. This is one of the reasons why 4K cannot be popularized. Another point is that you want to perfectly support 4K transmission. The HDMI standard must support the 2.0 specification. The theoretical transmission distance of the HDMI cable is 10-15 meters. Above this distance, it needs the support of relay equipment. The final word is "cost."

Difficulties II: Rear-end display devices are also pulling back legs

Not only these, in the security industry video playback devices are generally LCD monitors, monitoring equipment in ultra-high definition is too small, restricting the development of 4K.

So 4K faces so many difficulties, the popularity of 4K can only be the illusion of the mirage? The blue interstellar Jiao Chengping said that in fact, 4K is still applied in some industries. Take the railway station as an example, a 4K camera is used in front of the square, and the monitoring scope can basically cover the entire square in front of the station. At the same time, the pedestrian's appearance can be basically seen. . So 4K is not without its place. Its advantage is obvious.

The popularity of 4K depends on whether the development of the technology can solve the massive HD data, 4K ultra-high definition video, large bandwidth consumption, ultra-high definition video decoding and other issues. As long as these problems are overcome one by one, 4K will become an irresistible trend.
