Di Lepu breaks through the virtual and real studio boundaries to achieve 1+1>2
Release date:



Virtual studio is a unique TV program production technology developed in recent years. The emergence of virtual studio has brought a revolution to video production and TV broadcasting. With the maturity of virtual technologies, more and more program groups and TV stations choose virtual studios.

Recently, during the 28th Beijing International Radio, Film and Television Exhibition (BIRTV2019), Liu Fei, technical engineer of Shenzhen Dilupu Digital Technology Co., Ltd., introduced to DVBCN reporter how the combination of virtual studio technology and real-life studio will produce. Sparks.

Di Lepu breaks through the virtual and real studio boundaries to achieve 1+1>2

Virtual and real separation: 1<1

Often, traditional studios require a venue, a variety of sets, and beautiful lighting, as well as different screen styles depending on the style and budget of the show. In this way, if there are multiple programs in the same studio, it is necessary to constantly change the scenery and lighting to ensure that different programs are presented.

The background of virtual studios is mostly computer-generated and can change rapidly, which makes the design of colorful studio scenes very economical. However, virtual studios are not without drawbacks.

'After all, the virtual studio relies on the image synthesis. First of all, in the virtual case, can you achieve the perfect edge of the edge? There is no absolute answer. The character stands in the image, and the light will produce partial shadow and dark light. The noise generated will affect the image; secondly, the host and the guest wearing in the virtual studio, the color system may be close to or coincide with the background color, resulting in no image,' Liu Fei said.

Combination of virtual and real: 1+1>2

Di Lepu focuses on virtual studio development for more than ten years, from two-dimensional to two-dimensional half, near three-dimensional to the current stage, the rendering engine is iteratively updated, and the rendered environment is more realistic. At present, Di Lepu operates Envision 3D virtual studio system, Top3D-Set 3D virtual studio system, Freelance virtual studio system and Ulti-Dream AR studio.

Especially the advantage of AR studio, Liu Fei believes that with the development of the display industry, the resolution is getting higher and higher, the dot spacing is getting smaller and smaller, and the clearer details can be seen on the screen. The combination with the real thing realizes the traversal between the virtual scene and the real scene. In addition, it eliminates the occurrence of water ripples affecting the viewing experience during the shooting of the camera, and changes the defects such as monotony and limited field of the real studio column. Combines the unique sense of integration in the real studio. “It’s not just the combination of the advantages of the two, but the realization of the effect. The new form is presented to the audience, which is also quite novel for them.”

It is understood that the AR studio has the characteristics of “one-time equipment construction and arbitrary column production”, which combines the advantages of real-life studios and virtual studios, and finally achieves a real natural and intuitive effect. The host can quickly integrate the program environment. In addition, since the virtual space is displayed in real time, the foreground character does not need to be squatted, and the color of the host and the guest's clothing color is no longer restricted.

5G new empowerment

On June 6, the Ministry of Industry and Information Technology officially issued 5G commercial licenses to China Mobile, China Telecom, China Unicom and China Radio and Television. China started the 5G commercial year. In the field of broadcasting and television, the high speed and low latency of 5G networks will promote the technical exploration of broadcasting and television at the technical and product level. Liu Fei believes that with the arrival of 5G, through the innovation of 4K, 5G, IP and other technologies, the audio-visual industry will usher in new development.

For the new empowerment of 5G, Liu Fei said that the characteristics of 5G large bandwidth can be supported as an industry chain: First, whether it is television or film industry, it can be rendered in the form of cloud rendering; secondly, the production of college media information By uploading to the cloud platform through 5G, users and radio stations can purchase works on the cloud platform, thereby achieving multi-point cooperation.

Regarding the development of Di Lepu in recent years, Liu Fei said that Di Lepu has been committed to the broadcasting industry, and its domestic and international performance has continued to grow. In recent years, it has also actively expanded overseas markets, and has also deployed in the education industry, but No matter in which aspect, we are concentrating on making new technologies available to users, allowing users to have more new choices, and also hope to bring new programs to the public.
