Design And Implementation Of Program Management System With Video Server As Center

The arrival of the digital age, the television broadcast content stored from thechanges in the tape storage hard disk storage, now established production and broadcastconvergence network has become the development trend of China’s radio and television,specifically through the introduction of foreign high-performance video serversachieved major broadcast equipment. Supporting software and video servers is notsuitable for the needs of domestic television and often expensive, and therefore, thepotential in the research and implementation of a video server-centric networkautomatically broadcast control system according to the specific needs of the domestictelevision inevitable. This subject research and design to the center of the video serverprogram management system is used to achieve the acquisition of broadcast material,preview, review, upload and manage all-digital system, the entire television networkbroadcast automatically The control system of the basic system.Video server-centric program management system is divided into four sub-modules:upload management, program management, series single management, bulk upload.This thesis needs analysis of each module, and then completed three angles from thedatabase, server and client system design and implementation. Its main tasks are asfollows.1. Upload Management: DeckLink capture card and audio and video codectechnology to complete the broadcast of the material collection and preview, and AGC(Automatic Gain Control) to achieve the volume control and the use of improved filetransfer mechanism to achieve material file upload.2. Program management: Web Service for program information filtering, querying,deleting, and association, favorite’s management; Material document review alsodesigned to ensure the safety of the material contents of the file.3. Series single management: Web Service for series single information creating,modifying, deleting and management and using improved file transfer mechanism toachieve the material file upload, move back; while still achieving the tandem singlematerial file review. Bulk upload: Improved file transfer mechanism and multi-threading technology toachieve a simultaneous multi-material file upload. When the material file at the sametime need to be uploaded to the video server, the system can easily and quicklycompleted.The subject to achieve the video server-centric program management system hasmany domestic televisions. Feedback from the user point of view, the system is stableoperation, excellent performance, simple operation, to achieve the desired objectives;the system has also been given a higher rating.
