Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:
Like Fig. 1-2, the Asia-Pacific Chinastar data receiving system of present embodiment is characterized in that comprising: the receiving system, performance recording system and the program data automatic synchronizing unit that link to each other successively.
The improvement of receiving system: east, Asia-Pacific receiving station hardware components mainly is made up of satellite antenna, Ku wave band tuner, satellite data receiving card, receiving computer four parts.The SkyMedia-200D that the satellite data receiving card that Amstar network company adopts in receiving station is produced for Telemann company.SkyMedia-200D satellite data receiving card is the pci interface form; The PCI-X interface of the incompatible existing computer system of its interface; Because rack-mount server all adopts PCI-X or PCI-E expansion interface at present; Therefore this card can not use on present rack-mount server, can only on common industrial computer or desktop computer, use.
Satellite data receiving card is equivalent to a network interface card in system, from the data flow transmitted signal, take out the datagram that adopts the encapsulation of MPE multi-protocols, supplies receiving system to carry out further data processing.For receiving system, only need the MAC Address of correct configuration satellite data receiving card and bind an IP address, just can carry out the reception of program data.Slave unit stability and easy to maintenance setting out, TV station's all machine room computer systems at present all adopts rack-mount server or rack work station.Therefore in the improvement of receiving system, selected the satellite data receiving card TBS-6920 of PCI-E interface, to adapt to the PCI-E slot of IBM X3650 server.East, Asia-Pacific content divides transmission/reception system to adopt the MAC address authentication modes to carry out data to different receiving stations to include control; Through in the APETSK file, different MAC Addresss being received the setting of data; Prevent that the complete website of Data Receiving from repeating to receive identical data once more, also can be provided with simultaneously different receiving stations to same shelves program interruption different with the sheet advertisement.For TBS-6920 satellite data card, in the 24C02 chip of information stores such as its MAC Address on card, can revise MAC Address through instruments such as programmable devices equally.But TBS-6920 provides the change MAC Address convenient mode, in the IP of satellite card Data Receiving management software, MAC Address can be set directly.
The improvement of performance recording system: east, Asia-Pacific data receiving system adopts the unit mode to work, and unit is accomplished the reception of program and recorded work.Recording on the way of output of program, east, Asia-Pacific recording system software carries out the decoding output of MPEG-2 file through Stradis 260 video cards, adopts video tape recorder or hard disk to broadcast to upload website to carry out the work mode of operation that performance recording or broadcast are uploaded.The program file that receives also can directly be duplicated by this system; Modes such as employing software transcoding are transferred to broadcast system; But owing to have with subsidiary programs such as sheet advertisement and column propagation sheets in one grade of program; The layout more complicated of concrete program, only if do not need in the broadcast items with the sheet advertisement, otherwise be impossible adopt the mode of file copy transcoding to carry out the program broadcast to upload in practical operation.
It is no problem that the mode of operation that Asia-Pacific Chinastar recording system adopts is at present used under the fewer situation of the program amount of reception every day.When the program amount was big, if adopt the mode of operation of original system, and the program that will in program, break for commercialsy, then program uploaded and broadcasts that to compile single workload will be very big all.The program that particularly in concrete program, breaks for commercialsy need carry out advertisement and broadcast the setting of compiling single and advertisement insertion point, and these two work are very loaded down with trivial details, also are easy to make mistakes.From increasing work efficiency and reducing error rate; Native system has been developed the transcoding that is used for the light entertainment and has been uploaded software; With the whole transcoding of local advertising program and the program material that receives is the single program file that meets the broadcast system form; And upload to the broadcast system server automatically, thereby simplified the broadcast upload process of light entertainment.Program data information during this transcoding software is shown with TAB_TASK through the TAB_FILE table that reads east, Asia-Pacific data receiving system database file APECN.MDB; Broadcast the setting on date according to program, information such as all programs that belong to a certain broadcast date and concrete program file that program inside comprises and promotional literature are added in the transcoding task list frame.Owing to have no the information relevant in the APECN.MDB database with program length; In order to make the program personnel of uploading to understand the length of wall scroll program and the total length of whole shelves program; The transcoding program is when calling in programme; Obtain the length information of the corresponding MPEG-2 video file of every program synchronously and add in the transcoding task list frame, calculate the total length of whole shelves program simultaneously.
Trans-coding system is provided with local advertising program material storehouse, through adopting the mode that imports video file the program length information of ad material is added in the database.Advertisement in local advertising program material storehouse can directly be dragged to any position of a certain shelves program and intercut.The transcoding mission bit stream read finish after, operating personnel adjust the inner particular content of each grade program according to broadcast arranging, and can adjust and delete inner ad material and the column propagation program of a certain shelves program.Simultaneously local advertising program material information is inserted in a certain shelves program, and freely adjusts the insertion position of local advertising program in whole shelves program.After adjustment finishes to program, click the transcoding button and just can directly merge transcoding, and the program material that transcoding finishes is transferred to the broadcast system server automatically each grade program.
If calculate to receive 9 grades of light entertainments of nearly 6 hours every day, the artificial program material adjustment time, the transcoding uplink time was about 2 hours automatically in 5 minutes.The program that has not only saved 1:1 broadcasts upload process, has reduced tradition and has uploaded and broadcast the error rate of compiling list, has also increased substantially operating efficiency and broadcast quality simultaneously.For the program material situation is effectively supervised and monitors; The transcoding site configuration Decklink SDI digital video adapter; Through configuration to transcoding software; Ad material in the double-click local advertising material database or the program material in the transcoding task list can output to data monitor through the Decklink video card with programme signal, carry out the monitoring that supervises of program image quality and sound quality.With respect to Strandis 260 video cards that original system adopts, the equipment input is lower.
The improvement of program data automatic synchronizing unit:, therefore have network security problem because east, Asia-Pacific receiving system need be carried out the feedback of program reception condition through the internet.Though Amstar Network Transmission company is provided with very strict network security policy on receiving station, security of system is very high in actual use.But in order to ensure the safety of broadcast system and later stage program making system, it is convenient and swift to guarantee that simultaneously program receives and uploads, and we have adopted the separately mode of design of receiving station and transcoding website.Receiving station mainly is responsible for program data and is received, and the transcoding website mainly is responsible for the transcoding and the broadcast of program and is uploaded.The ftp server end software that on receiving station, disposes is Serv-U 9.0; The ftp client software that on the transcoding website, disposes is CuteFtp; File timing synchronization function through configuration ftp client software; Realized the synchronous automatically of receiving station and transcoding website program material, regularly be synchronized to broadcast transcoding website with program file and the receiving system database file APECN.MDB that receiving station receives every day, and the whole system structure is as shown in Figure 1.In order to guarantee network security; With broadcasting on the transcoding website Symantec endpoint enterprise version anti-virus software has been installed all at receiving station; And having disposed corresponding security strategy according to network characteristics, receiving station and broadcasting between the transcoding website connects through gigabit Ethernet mouth equity.
