Beijing TV Station SOA Based Network Production System

The BJTV New Station Network System was designed starting in May of 2005, with installation completed by August 2008. On-Air operations commenced on April 1st, 2009. The design of whole network system is HD and SD compatible, and features a fully file-based production workflow. The system includes backbone platform system, News system, Sports system, Normal post production system, Deep post production system, Station Promo editing system, Ingesting system, Studio room sharing network system, MAM system, Program planning (Chief-Editor) system and production management system. The total storage capacity is: on-line 500TB, near-line 100PB. The total number of servers is 500, and the total number of terminals is over 1,200. — The system is constructed by adopting SOA concept, and utilizing backbone platform to facilitate integration and connection of every business system. Based on the requirements of broadcasting and TV industry, the system utilizes EMB (Enterprise Media Bus) concept. Enhancements to standard ESB technology were used to manage the different types of distributed storage in the system, to realize transferring of media files among system, and for format conversion. The backbone platform created by the adopting ESB+EMB structure makes the new BTV production network system easy to manage. It also provides secure operation with high efficiency. In the future, a new business system could be integrated based on this platform. Since the technical concept of network production system is relatively matured, the article intends not to describe further on construction technologies of the BTV network production system. The article, rather, focus on how to construct a large size network production system by utilizing SOA technology to integrate multiple network production systems.
