Abstract
The broadcasting video server system using BS3000 broadcasting video server as main machine consists of collecting and loading station, browsing and indexing station, program data managing station, program list editing station and data server. The accurate control and accurate broadcasting can be realized with the system by applying techniques of distributed collection, distributed storage, distributed audit and distributed broadcast as well as applying technique of real time synchronous collection for various formats of program data.
Description
Technical field: the broadcast video server system that the present invention relates to automatic broadcast of TV programme and control technology.
Background technology: the broadcast of the TV programme of traditional dribbling coupling system mainly is to adopt many players and broadcast control cut bank composition, all be recorded in all programs that will broadcast on the tape, and be placed in the different players, by broadcasting the control cut bank, controlling all players moves, equipment mainly is the Sony Corporation of Japan, the product of the GVG company of the U.S., and there is following defective in this traditional broadcast system: a. program is reused loaded down with trivial details, and calling of all programs must be handled according to linear mode; B. the equipment that involves of system is numerous, increases attendant's workload; C. broadcast items all uses tape to preserve, strict to the tape instruction; D. adopt manual operations, increase unsteadiness; E. the magnetic drum of player is changed the frequency height, and the magnetic drum life-span of video tape recorder only is 500 hours.
Summary of the invention: purpose of the present invention is invented a kind of control convenience, maintenance cost paper, program and can be repeated to broadcast for overcoming above-mentioned defective, with the equipment that computer broadcasts and controls station synchronization, broadcasts video in system.
The present invention is achieved in that it is that employing BS3000 broadcast video server is main frame (core), and upload work station, browse the distributed broadcast system that retrieval work station, program data management work station, programme editing station, database server etc. are formed by collection, its adopts accurately broadcast and precision Control Technology.Its principle as shown in Figure 1, the program that broadcasts is all collected in the hard disk of broadcast video server, decoding channels by video server broadcasts program, deliver to the broadcast cut bank, simultaneously by other Control work station (PC), by the control road, video server and broadcast platform are controlled, realize the automatic broadcast of program.
It adopts the hard disk of " estimation is surveyed and the dual decoding method " to intercut and get ready the broadcast technology; program broadcasting time is calculated technology automatically; it is chiefly directed to three aspects; comprise that memory manual triggers and other manually broadcast the time of operation; carry out the unsteady location of time and program bar according to the priority of the mode of broadcast; the timely protection of programme real time error and amended programme; with multiple form program real time data synchronization acquisition technique; it with the video-audio signal of video tape recorder or satellite through coding once; just can on hard disk, form MPEG1 simultaneously; MPEG2; the data file of MPEG4 and Ralmedia; saved the time of user media data upload; the correctness and the correspondence of the multiple format media data of same content have been improved; satisfy more extensive application demand, have very big using value various media formats.This system broadcasts application at the program of three channels of TV station, adopts three BS3000 broadcasting servers, five acquisition workstations, and two external RAID disk arrays have realized that distribution collection, distributed store, distribution are examined, distributed broadcast.Can easily set up the large-scale broadcast system of tens passages by this BS3000 server.
Description of drawings: accompanying drawing 1 is broadcast video server system block diagram of the present invention;
Playing control system block diagram when accompanying drawing 2 is Video service;
Accompanying drawing 3 is traditional playing control system block diagram.
Embodiment: BS of the present invention broadcasts video service system as shown in Figure 1, by broadcast video server 1, Ethernet switch 2, upload work station 3, upload player 4, go up pre-blue 5, down pre-blue 6, upload player 7, program search down and browse work station 8, Broadcast Control work station 9, broadcast with player 10, broadcast cut bank 11 and constitute.
It adopts BS3000 broadcasting server (1) to make main frame, server host (1) connects program search by Ethernet switch (2) one ends and browses work station (8), the other end is uploaded work station (3) with BS3000 and is connected, and uploads and is connected with down pre-blue (6) on the work station (3), uploads with player (7) down.The last end of server host (1) is connected with and uploads usefulness player (4), goes up pre-blue (5), be connected with Broadcast Control work station (9) in the upper end of server host (1), BS3000 server host (1) output is connected with and broadcasts cut bank (11), output signal is sent into broadcast cut bank (11), on server host (1) and broadcast switching machine (11), also be serially connected with and broadcast with player (10).
In sum, it carries out distribution collection, distributed store, distributed broadcast technology broadcast video server system of the present invention, and its equipment is simple, control is convenient, low, the good stability of maintenance cost, and program can repeat to broadcast and not be damaged.
Claims (4)
1, a kind of broadcast video server system, it is characterized in that adopting the BS3000 broadcast video server to make main frame (1) and upload work station (3), browse retrieval work station (8), program data management work station by collection, programme editing station, data server etc. constitute distributed broadcast system.
2, broadcast video server system according to claim 1 is characterized in that BS3000 server system main frame (1) connects program search through Ethernet switch (2) and browses work station (8), and the other end is uploaded work station (3) with BS3000 and is connected; Upload be connected with down on the work station (3) pre-blue (6), down upload player (4), go up pre-blue (5), be connected with Broadcast Control work station (9) in the upper end of server host (1), the output of server host (1) is connected with and broadcasts cut bank (11), also is serially connected with on server host (1) and broadcast switching machine (11) and broadcasts with player (10).
3, according to the described broadcast video server system of claim, it is characterized in that broadcasting and get ready broadcast technology and the collection of multiple form program real time data synchronization with the estimation detection and the hard disk skewer of dual decoding method, it is the video-audio signal of video tape recorder or satellite, through once encoding, just can on hard disk, form the data file of MPEG1, MPEG2, MPEG4 and RealMedia simultaneously.
4,, it is characterized in that carrying out distribution collection, distributed store, distribution and examine, distribute and broadcast and precision Control Technology according to the described broadcast video server system of claim.
