"Fashionable" 5G

Right now 5G has become a "fashionable" popular word. But if you want to know how 5G will change the Spring Festival Gala, we must first figure out what 5G is. 5G is the latest generation of cellular mobile communication technology. High data rates, reducing delays, saving energy, reducing costs, improving system capacity and large -scale equipment connection are 5G performance goals. The data transmission rate of 5G network is much higher than the previous honeycomb network, up to 10Gbit/s, which is faster than the current cable Internet, 10 ~ 100 times faster than the 4G LTE honeycomb network. In order to meet the large data transmission of high -definition videos and virtual reality, 5G needs to achieve the download speed of 50 gigrees per second, that is, you can download more than 10 high -definition videos in 1 second. To meet the real -time application of autonomous driving and remote medical treatment, the level of 5G air interface delay needs to be about 1 milliseconds.

Undoubtedly, 5G will play an important role in all walks of life in the future. Right now, the digital transformation of production infrastructure and social infrastructure based on 5G networks is making technologies and applications such as big data, cloud computing, and Internet of Things from conceptual to actual, from abstract to specific.

"Pioneer" in the 5G era -ultra -high -definition live broadcast

Since entering the 5G era, ultra -high -definition live video has been the "pioneer" in the field of 5G applications. The arrival of 5G allows 2020 to be called a year of resolution revolution. In the Spring Festival Gala 2020, under the support of 5G networks, the 4K+VR panoramic ultra -high -definition live broadcast has been achieved. In the Spring Festival Gala 2021, 8K production was carried out, and the IPTV platform inside the main station conducted live tests in 8K channels. Everything indicates that 8K will become the star of tomorrow. So does this mean that the 8K viewing experience is better?

4K is 4K resolution, which belongs to ultra -high -definition resolution (4096 × 2160 pixels). Under this resolution, the audience will be able to see every detail and close -up of every detail in the picture. From the perspective of resolution, the resolution of 8K (7680 × 4320 pixels) is 4 times (3840 × 2160 pixels).

The number of pixels that can be distinguished by people's eyes is limited, and the distance between the viewing and the vision of the audience will also have a certain impact on the movie viewing experience. Various data show that although 8K has obvious advantages in a short distance, according to our viewing distance in daily life, 8K and 4K are not much different. So when we watch the Spring Festival Gala, we can choose the appropriate movie viewing mode according to our own conditions without pursuing extremely high resolution. Of course, under the wave of 5G technology upgrades, 8K will still be a subject worth research. It can provide higher resolution, and the picture can also present more information, which will bring us a different viewing experience.

5G network technology is a revolutionary technology change in the epoch -making, and ultra -high -definition video technology is an inevitable trend of TV upgrade. Every new achievement will bring changes to the world and make the world better. At that time, what form will our Spring Festival Gala become? This is an interesting issue worth thinking about.
