The process of radio and television program production and broadcasting can be roughly divided into four parts: gathering, transmitting, producing, and broadcasting. Cloud broadcasting technology connects video streams to the cloud through technologies such as 5G and cloud computing, allowing program production and distribution to be done in the cloud and achieving end-to-end video transmission. At present, the ongoing 24th Beijing Winter Olympics has applied cloud broadcasting technology, and its successful application has not only brought a luxurious audio-visual feast to global audiences, but also sparked discussions on the cloud broadcasting of programs within the industry. "Cloud broadcasting" has also been recognized as one of the top ten key technologies in the Chinese broadcasting and television industry in 2021 by the State Administration of Radio and Television.
Nowadays, the innovation of radio and television programs poses severe requirements on the production venue and surrounding environment. Expensive and bulky broadcasting equipment, specific broadcasting locations, and outdoor network environments are all limiting factors. The collection and transmission of program materials may also suffer from uncertainties such as instability, loss, and long delays.
ORIVISION, which has long been deeply involved in the field of IP-based video transmission, has made a significant contribution to cloud broadcasting. ORIVISION's technology and video codecs determine its important role in the cloud broadcasting workflow, specifically in the "transmitting" part of the "gathering, transmitting, producing, and broadcasting" process, as well as the simple "producing" part. "Transmitting" is based on IP video transmission, while "producing" involves simple program production.
ORIVISION's video encoder hardware can propagate high-definition videos based on aggregated networks, ensuring reliable and low-latency video transmission even in harsh outdoor conditions. ORIVISION's H.264/H.265 video codecs can replace traditional video capture solutions by encoding SDI video signals from cameras and transmitting them remotely, end-to-end, SDI streaming encoder with low latency and encryption, for subsequent monitoring and production purposes. Even in outdoor locations such as high mountains and forests, signals can be effectively, accurately, and securely transmitted.
ORIVISION's multi channel encoder series effectively solve the problem of video feedback timeliness, providing reliable video cloud transmission assurance for cloud broadcasting in the radio and television industry and laying a solid foundation for cloud broadcasting.
For outdoor live broadcasts of sports events, the director's desk needs to perform operations such as video source overlay, switching, logo imprinting, and adding static backgrounds before the live broadcast. ORIVISION's equipment fully meets these basic production functions.
With the improvement and popularization of cloud broadcasting technology, the application scenarios for cloud broadcasting are full of imagination. In addition to large-scale events like the Winter Olympics, cloud broadcasting technology will also be increasingly applied in various types of remote enterprise activities, on-site emergency command, school events and sports competitions, and live news production. ORIVISION's 4k streaming encoder and other products and solutions, combined with cloud broadcasting technology, demonstrate unique advantages in ultra-low latency and ultra-high-definition video transmission indoors and outdoors.
In the 14th Five-Year Plan, it is mentioned that by 2025, "broadcasting, television, and Internet audio-visual media platforms will achieve IP-based, cloud-based, integrated, intelligent, and standardized development, and a new layout of media collaborative development will be basically formed, significantly enhancing service capabilities for users." Therefore, in the coming years, building a program production system centered on cloud technology is an inevitable direction of development in the broadcasting industry. Cloud broadcasting platforms for television channels have already tasted success in variety shows, and large-scale applications like real-time cloud broadcasting of the Beijing Winter Olympics are taking place. From the central to the local level, cloud broadcasting technology is being popularized and promoted. ORIVISION will also follow the national 14th Five-Year Plan, seize the opportunity of technology to assist audio-visual integration, contribute its technological strength to the upgrading and transformation of the industry, and bring high-quality content and experiences to the audience.
