Description of drawings
For the content that makes the utility model is more clearly understood, below basis specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation, wherein
Fig. 1 is the structured flowchart of TV station's live broadcast system of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:
Like Fig. 1; When TV station's live broadcast system of present embodiment is worked; The DFS-800P of Sony), multi-image divider, 8*8 digital video matrix handle camera signal, programme replay signal and picture-in-picture signal carry out after digital distribution handles through the balanced allocation units of digital video (adopting Leitch DVSE 6800+ series), divide three the tunnel to send stunt cut bank (model: respectively.The digital audio and video signals of the vision signal of stunt cut bank output and the output of broadcast live sound console carries out the audio signal embedding through audio signal embedding processing unit to be handled; After the digital video signal after the embedding is through the matrix allotment, directly send programme televised live to upload website and include collection.The digital signal of stunt cut bank output sticks into the display that send the broadcast live chamber after the capable analog-converted through Leitch ENC6800+ analog mixed-signal encoding board simultaneously, supplies broadcast live chamber host and welcome guest to watch.
The configuration of camera unit: the space of studio is not too large usually; In the selection of video camera; Adopt two little high-definition cameras of SONY PMW-EX1, this video camera possesses the SDI digital signal output of high definition or SD form, establishing shot host of two video cameras; One is used to take studio's panorama and part welcome guest picture etc., and the PMW-EX1 video camera is set to high definition down conversion mode of operation.The test result of SONY PMW-EX1 video camera in early stage system constructing process is better, and image quality is also better in actual the use, therefore there is no need to be provided with special light units.In order to improve the studio picture effect; Need be the 3rd video camera of system configuration; This video camera is the integrated camera of SONY BRC-300P band cloud platform and camera lens control, and for it has disposed SDI numeral output option BRBK-302, thereby make this video camera can export the SDI digital signal.In order on the control program interface, intuitively to see camera views; On video camera control website, disposed Decklink SDI video card; The video pictures that the output signal of BRC-300P video camera is input to Control Software is supervised in the window in advance, thereby is more convenient for the adjustment of camera views and supervises.
This video camera is supported the VISCA control protocol, can carry out through RS-232 or RS-422 interface that push-and-pull moves and the isoparametric straighforward operation of aperture white balance to video camera.Traditional calculating machine system has only the RS232 interface, because there is certain distance control room and studio, and the RS232 command range is limited, and for guaranteeing the reliable remote control of video camera, system adopts the RS422 mode that video camera is controlled.In native system, on DELL R5400 rack work station, disposed the PCI-1602 multifunctional serial port card that grinds Chinese workers' control, this jig is equipped with two RS422/485 serial ports expansion functions, and system realizes the Long-distance Control to the BRC-300P video camera through PCI-1602.System is installed in PCI-1602 multi-function extended card and video camera Control Software on the programme replay website, carries out the control of video camera by the programme replay personnel, through same computer realization programme replay and the video camera control in the live process.
The configuration of programme replay unit: in live process, need carry out the playback of video-audio program usually; The program amount of considering playback is not a lot; From the flexibility and the reliability of programme replay, directly adopted non-volume website to carry out programme replay based on Edius Pro software, non-volume main frame adopts DELL R5400 rack work station; Configuration Canoups HD SPARK Pro video card is as the output of video/audio signal; This video card is pure output card, can directly export the SDI digital signal of high definition or SD, possesses the output function of AES DAB and simulated audio signal simultaneously.The SDI digital signal of HD SPARK Pro video card output send Leitch digital distribution plate to carry out allocation process, and the AES digital audio and video signals directly send the broadcast live sound console.
Video picture-in-picture system configuration: adopting video picture-in-picture effect in the interview class program is a kind of mode relatively more commonly used at present; Realization for this effect; Can accomplish through the hardware capability of multistage M/E cut bank, also can realize this effect through the mode that the computer system and video card combines.A kind of mode in back is adopted in the native system design, and input cost is lower on the one hand, can increase more special-effect through computer system on the other hand.System host adopts DELL R5400 rack work station; Dispose two bluefish Bluefish444 SD|SingleLink Pro video cards; This card is the full duplex card; Possess the ability of input of one tunnel vision signal and the output of one tunnel vision signal,, realized the video picture-in-picture effect that external motion video of two-way and one tunnel computer-internal activity context picture superpose through programming.Sending into the two-way camera views of video card dispatches through Leitch 8*8 character matrix.Through two output channels of two video cards, system can export the video pictures of two different-effects at most simultaneously.
Cut bank configuration: because the equipment such as HD SPARK Pro video card that the SONY PMW-EX1 video camera that system uses, BRC-300P video camera and non-volume website use all are not with synchronous input function; In order to realize the normal switching of programme signal; System adopts SONY DFS-800P cut bank to carry out the signal switching; This cut bank is small-sized 8 road cut banks, can carry out time base correction to each road signal, thereby realizes the synchronous switching of signal.
Performance recording is gathered site configuration: because the widely popular concentrated mode of uploading is all adopted in post-production at present; So being provided with in live broadcast system performance recording mode; Directly adopt the computer acquisition mode; In the post-production system, increased a programs and uploaded website, in live process, uploaded site apparatus in conjunction with original program and adopt two covers to upload the active and standby collection that website carries out programme signal.Upload the video file employing MPEG-2 D10 50Mb/S compressed format that website is gathered; The MXF form encapsulates; Program material directly collects in the optical fiber disk array of post-production system, and the post-production system can directly call program material and carry out the program post-production.
Multichannel image splitter: because the restriction in space, studio; System adopts Miranda Kaleido 16 road multi-image dividers; To 3 road camera signals, 1 tunnel non-volume playback signal, 1 road picture-in-picture video signal; And the master of cut bank cuts and preparatory prison signal is kept watch on, and display unit has directly adopted 19 cun widescreen displays to carry out rack and installed.
Obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not to be qualification to the execution mode of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all execution modes.And conspicuous variation that these spirit that belong to the utility model are extended out or change still are among the protection range of the utility model.
