Kernel calculation and exchange method of kernel server

Abstract

The invention includes kernel calculation and exchange units based on IP and soft exchange architecture. The units carry out kernel calculation and exchange of multiple routes of TS code stream data by using following steps: (1) through multimedia process bus, obtaining multiple routes of TS code stream data from peripheral interface unit; (2) after conversion treatment is carried out for multiple routes of TS code stream data, and unpacking operation is carried out; (3) soft exchange switching is carried out for unpacked code stream data; (4) after multiple statistical multiplexing, packing and relevant data format conversion process are carried out for soft exchange switched code stream data, data are output passing modulated divided circuits through peripheral interface unit. The method makes packed exchange of crossing platforms based on broadcast transmission network possible. Thus, the invention is convenient for exchanging and switching broadcast program.

Description

technical field [0001] The invention relates to a front-end broadcasting device in a digital radio and television interactive system, in particular to a core server, especially a core computing and switching method of the core server. Background technique [0002] With the continuous development of computing technology, chip technology, communication technology, and information compression technology in the past ten years, the cross-platform, large-capacity, and packetized exchange of information flow has been promoted, which has led to the emergence of new services. New business and new economy are driving the rapid progress and development of human society. [0003] With the determination of the next-generation network (NGN) standard, the interconnection and intercommunication of broadcasting networks, computer networks, and telecommunication networks is becoming a reality. Under this environment, cross-platform and multi-service operations and packetized switching based o...

AI Technical Summary

Problems solved by technology

[0004] Due to the closed and decentralized nature of existing digital broadcasting network equipment and the technical system based on these properties, it is difficult to meet the current and future needs of cross-platform multi-service operation and exchange. The physical interface of radio and television equipment can only be interconnected with related radio and television equipment, which cannot meet the needs of cross-platform wide-area switching required by today's business development;

[0005] Scattered equipment: The broadcasting of radio and television programs is a very complicated process, involving many links such as demultiplexing, multiplexing, video services, scrambling, and QAM modulation. Each of these functions is an independent device. When digital When the number of broadcast programs increases, the number of broadcast equipment will be huge, the reliability and security will be reduced, and it will be difficult to manage and maintain

[0006] Difficulty in program exchange: The interconnection of existing radio and television equipment mainly relies on the hard connection of physical interfaces. If you want to achieve program exchange, you can only rely on plug-in connections, which greatly reduces security and reliability.
