The 8K ultra -high -definition video is a new round of intergenerational evolution after the video technology following the simulation, the clearing, the high -definition, and the 4K ultra -high -definition. It is a development direction of a trillion -level emerging industrial cluster. Beijing Radio and Television follows the overall technical route of "4K first, take into account 8K", seize the new round of traditional TV industry transformation opportunities. On December 31, 2021, the first nationwide to provide 8K ultra -high -definition video programs for the majority of audiences in the country. The TV channel "Winter Olympics Documentary 8K ultra -high -definition test channel", relying on the 8K technology to develop the advantages, conducts large, medium and small screen cross -screen integration and spreading, becoming a traditional TV industry transformation practice that explores the 5G era and faces the future Meaning pioneer.

Exploration of Beijing Radio and Television 8K ultra -high -definition test channel

As the first TV channel to provide 8K ultra -high -definition video programs for the general audience in the country, the "Winter Olympics Documentary 8K ultra -high -definition test channel" provides technical support for the Beijing Winter Olympics and the Winter Paralympic Games. The communication network provides social broadcast services. After the end of the Winter Olympics, the "Winter Olympics Documentary 8K ultra -high -definition test channel" will be revised on September 21, 2022 to "Documentary and Education 8K ultra -high -definition test channel", and transfer to normal 8K ultra -high -definition Broadcast of the show,

The broadcast of the "Winter Olympics 8K ultra -high -definition test channel" has two major practical meanings.

On the one hand, for the development of the 8K ultra -high -definition video industry in China, the "Winter Olympics Documentary 8K ultra -high -definition test channel" has allowed our country's 8K ultra -high -definition video technology to transfer from the laboratory stage to the landing stage. Later editing, special effects production, audio production, transmission links, integrated broadcast control, terminal display and many other links such as 8K ultra -high -definition video system. 8K ultra -high -definition video is suitable for 5G technical environment. In the current stage of 4G to 5G transition and 4G, the "Winter Olympics Category 8K ultra -high -definition test channel" is the first to carry out the full process of the 8K ultra -high -definition video broadcasting. The key technical verification of the broadcast level, in order to build a set of technical standards that can support and lead the development of 8K ultra -high -definition video upstream, middle and downstream industries, this is strategic for the development of the 8K ultra -high -definition video industry in the world in China And global significance.

On the other hand, for the traditional television industry in my country, the changes in the field of intelligent mobile internet era have caused the traditional television industry to suffer a nearly subversive impact. Duan), non -linear viewing, short video rise, traditional television industry has passively transformed in the era of media integration, and has never got rid of the role of "catch -up". After the radio and television industry has the core technical resources of 8K ultra -high -definition videos, from simulation to numbers, from standards to high -definition to ultra -high -definition, and the current 4K to 8K evolution, the audiovisual technology has continued in the iteration of the radio and television industry.

8K ultra -high -definition technology promotes "cross -screen integration dissemination"

The transformation in the field of visual and audiovisual is based on technical guidance. Based on the technical advantages required for the previous round of reform, the technical advantage of the 8K ultra -high -definition video has made the 8K ultra -high -definition video make the radio and television industry a leader in 4G to 5G audiovisual changes. Opportunities, grasp the possibility of curve overtaking in the first opportunity. At the same time, the 8K ultra -high -definition video has also become the development fulcrum and transformation path of the traditional TV industry.

8K ultra -high -definition video excellent audiovisual experience fits the physical characteristics of the medium screen and large screens, that is, the super high -definition of the huge picture is presented, which makes the middle screen and large screen's irreplaceableness in user audiovisual behavior. "TV)" "has the possibility of returning to the center of the family center. In view of the sluggish status of the national outdoor screen (outdoor advertising) industry, the 8K ultra -high -definition video also provides opportunities for the" wake -up "large screen. Strict technical and environmental requirements, high production and operation costs, excellent medium (large) screen audiovisual experience constitute the limited factors of 8K ultra -high -definition video development operation subject, calling for a medium with strong technical reserves and non -marketization, (Large) The main body of screen operation leads the development of 8K ultra -high -definition videos. Under the constraints of such conditions, TV stations have become the best choice.

From the perspective of television, the dilemma of "media integration" currently facing TV stations also calls on TV stations to embrace new opportunities. From the perspective of technical links, the current "media integration" has a problem of different degrees of integration. In short, the unidirectional fusion willingness of large screens to small screens is strong. ) The communication effect has become an important evaluation indicator of many media institutions in media integration. However, a mature integration media environment should not be limited to small screens on the large screen content, but the mutual flow of large screens, medium screens and small screen content, that is, the so -called "cross -screen integration dissemination". In the first stage of media integration, the technical trend dominated by mobile interconnection makes the small screen lead, and to some extent formed the effect of technical black holes. The transformation and development of the radio and television industry for a long time and the goal and means of small screens are like the black hole swallowed the unique technical characteristics and industry advantages of the radio and television industry itself. A new generation of media fusion path with 8K ultra -high -definition video as the core is based on the technical link to achieve fully connecting communication environment. There is no longer a technical threshold between large screens, medium screens and small screens, and no longer a large screen direction to the direction of large screen direction. The unidirectional fusion of small screens can achieve seamless connections of large screens, medium screens, and small screen dissemination content and rapid conversion of communication scenarios. This path of "cross -screen integration and communication" can be released to the greatest extent to release the technical vitality and development demands of the radio and television industry and outdoor large -screen advertising industry in the current media integration stage. The "integration" of the communication agency in the new generation of communication has achieved the optimization of communication effects. In terms of large, medium and small screen cross -screen integration, Beijing Radio and Television Station conducted an exploration. In addition to the "Mid -screen, Winter Olympics 8K ultra -high -definition test channel"; 5G+8K high -definition video mobile application is also launched as "small screen" in January 2022. Video resources and the world's first video player supporting 8K interactive experience, supporting users to watch the live broadcast of Beijing Radio and Television 8K ultra -high -definition test channels and 4K/8K boutique programs; The opportunity of Olympic, driven by the policy of "Hundred Cities and Thousands of Cities" of the Ministry of Industry and Information Technology, the construction of 8K large screens and 8K demonstration communities in Beijing Radio and Television, more than 20 8K ultra -high -definition outdoor screens and 8K ultra -high -definition television landing in Beijing important scenic spots , Institutions and universities, and explore unified technical standards and new industrial models in practice.

The characteristics of the interconnection of all things in the 5G era make the 8K ultra -high -definition video break through the limitations of visual presentation technology. It is not only a development direction of a trillion -level emerging industrial cluster, but also releases the bud in the 4G era, such as virtual reality (VR) and and The industrial value of augmented reality (AR), the spilling effect brought by the 8K ultra -high -definition video application will become more and more obvious. This industrial characteristics allow the traditional television industry to obtain extremely extensive extension space. Traditional television industry will no longer be a TV station that provides audiovisual services for users, but should be a central nerve of emerging industrial clusters. The traditional television industry has obtained the triple transformation path of the television station, the radio and television industry, and the upstream and downstream industries.
