Shenzhen Integrated Services Network broadcast all processes interconnection case
The whole process of Shenzhen Media Group Integrated Services Network Interconnection Case Analysis
Shenzhen Radio, Film and Television Group as the key link Zhao
After years of system construction and development, domestic television production business systems at all levels of the basic form of the specific business aspects of private network systems. TV companies under the system provides the advantage of a number of different vendors have chosen to achieve different professional systems, the benefits of doing so is to get the functionality, performance, professional system is best for specific business sectors or the application of professional channels. But with the television production business development, new media applications, and media asset value changes required by the current operational system of production and gradually show the following questions:
physical interconnection between systems needs urgent, but the lack of a unified, efficient and economical mode of physical interconnection.
difficulties in information exchange between systems, metadata, media material, management and control information flow in various systems are not smooth.
systems business processes through difficulties and achieve cross-system business processes through existing barriers and needs of the very great expense.
More and more stations come to realize: how to eliminate information "island", the effective realization of the system interconnection, sharing of resources has become a television station now needs urgent solution.
Shenzhen Media Group TV content production and management of the whole process of integrated services network system (hereinafter referred to as "the whole process of Integrated Service Networks"), Shenzhen Radio, Film and Television Group and Chengdu Sobey Digital Technology Co., Ltd. jointly developed Taiwan of China's first integrated business system, is the original distributed digital network solutions to expand network of integrated services in Taiwan at a depth of attempts, but also the future development of new television models. This whole process of Shenzhen Media Group Integrated Services Networks to achieve interconnection, sharing of resources a brief analysis in the hope of other planning and construction of an integrated network of television stations, serve.
I. Introduction Shenzhen Media Group the whole process of Integrated Service Networks, is built on the basis of a media content asset management support for the set of satellites included, upload catalog, news production and broadcasting, program production and broadcasting, a distributed media asset management, news, programs and studio Room broadcast, advertising broadcast control program, including release to cover all of Taiwan's integrated content production overall business network system and information platform with Taiwan within the office and advertising management platform in close contact. The system consists of news production and broadcast networks, program production and broadcasting networks, media asset management system, hard disk broadcast system, centralized system of five parts included.
Shenzhen Media Group-wide scale process of Integrated Service Networks, the total amount of more than 200 sites; all kinds of editing, review films, dubbing, packaging, site 148; all for the collection, download, broadcast, transmission MegaServer Media Server, 38 sets; using multiple S2A8000, S2A3000 storage, online storage total of more than 15TB, fully meet the Shenzhen Radio, Film and Television Group has 10 sets of programs (including 9 sets the standard definition programs, via satellite, terrestrial and cable transmission platform, a set of pilot programs for the high-definition, digital cable platform in the broadcast), nearly 50 self-management part, the average daily volume of more than 10 hours home-made program requirements, but also provides ample headroom.
A system in a creative way to introduce a number of innovative technologies and organic these technologies integration, makes the system not only has the technology leader, but also has good operability and security.
Second, the realization of interconnection between systems
Shenzhen Radio, Film and Television Group, as chief engineer of Fufeng Chun said: "First of all, from the interconnection network to establish a large-scale production purposes and talk, aim first is to enhance the efficiency of the production network, the second is to reduce the running costs, particularly human cost, this is the meaning of interoperability. If you do not achieve interoperability, there are many discrete units sub-network system, the production process is not consistent. "
However, due to historical reasons, to the full realization of television production business systems interconnection, resource sharing, there is a huge obstacle, in particular in: there is no unified standard connectivity protocol; there is no uniform standard data file format ; no standard and well-defined interfaces.
The whole process of Shenzhen Media Group Integrated Services Network systems interconnection between various business systems developed by the Sobey's "Media Service Bus (MediaBus)" technology, using a number of industry-standard technology, and with the user, third-party manufacturers jointly designed interface specification, through the gateway device, to achieve the various business systems connectivity and interoperability between the high. This technology enables truly integrated business network open, sustainable development of the system.
Following the whole process will be comprehensive, Shenzhen Media Group business network interconnection between subsystems are to be introduced:
