Description of drawings
Fig. 1 is the structure chart of dynamic recording and broadcasting system first embodiment;
Fig. 2 is the structure chart of dynamic recording and broadcasting system second embodiment.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As can be known in existing television news studio, often need to comprise the collaborative task of performing in a radio or TV programme of finishing of staff of the multiple different division of labor such as program instructor in broadcasting, video reproduction teacher, tuner, subtitler, light controller, cameraman and announcer by aforementioned.Because the switching of program all is the manual operation of adopting, so be difficult to guarantee each staff's uniformity.In view of this problem, it is the supermatic dynamic recording and broadcasting system of television news studio of centralized-control center with instructor in broadcasting that the utility model has designed a kind of, make the switching of various programme signals all pass through the same control of instructor in broadcasting's central control board, reduced artificial factor by the instructor in broadcasting.
As shown in Figure 1, comprise in this dynamic recording and broadcasting system:
The shooting unit
The shooting unit generally is made of three video cameras, takes male announcer, narratress and two people's panorama respectively.
Video tape player
Video tape player can play back the news program that is recorded on the tape by video tape player.
The audio frequency sound console
The audio frequency sound console in order to regulate from announcer's the sound of sound, program interruption machine of sound, video tape player and the size of the sound of other extraneous signals, and various sound mix are broadcasted.
The program interruption machine
Store the news program, head, run-out and the advertisement that are not recorded on the tape in the program interruption machine, prepare against when needing spot and broadcast.
Film titler
Film titler generates the caption information that cooperates the program picture.
Instructor in broadcasting's central control board
Instructor in broadcasting's central control board is controlled by the instructor in broadcasting, is responsible for the workflow of each link in the coherent system, and the operation that each peripheral equipment is finished appointment is controlled in the transmission of complete operation information.
Cut bank
The signal that all are input in the cut bank is all mixed therein, exports broadcasting signal then.
The GPIO repeater
The GPIO repeater is at the designed a kind of special installation of recording and broadcasting system characteristics specialized designs of the utility model.In the program making and broadcast process of reality, the instructor in broadcasting finishes actual handover operation by instructor in broadcasting's central control board operation cut bank, just in numerous signal sources, chooses the conduct output that needs.When the instructor in broadcasting operated cut bank and carries out handover operation, variation had taken place in the switching state which road signal this device will perceive, and with position and time that these switching states took place, accurately notes, and used for thereafter editor again.
Above-mentioned video tape player, program interruption machine, film titler are video signal source.Whether the output signal of these equipment is controlled it by the instructor in broadcasting by instructor in broadcasting's central control board and is exported.The output signal of shooting unit and above-mentioned these equipment all exports cut bank to, is mixed therein, then as broadcasting vision signal output.
The audio frequency sound console is also by the control of instructor in broadcasting's central control board, and its output audio signal is as broadcasting audio signal output.
GPIO repeater and cut bank, the position and the time of being taken place according to the change records switching state of cut bank input signal.In addition, also can the linking to each other with the video wall in the studio of GPIO repeater, the indicator light on the corresponding indication TV wall is to point out each staff current switching state.
As seen, the dynamic recording and broadcasting system of television news studio of said structure all concentrates on instructor in broadcasting's central control board with all handover operations, by the unified operation of instructor in broadcasting.At this moment, other equipment operators are the supervision of operated equipment only, guarantee the operational excellence of its equipment, and do not need to carry out the manual switching operation.This will greatly reduce the interference of human factor in this process, program making is provided and broadcast process safe and reliability.
In addition, compared to the existing artificial more recording and broadcasting system of getting involved, the designed system of the utility model has been owing to adopted a large amount of Computer Control Technologies, make system function upgrading and transform and can realize convenient function upgrading and transformation by the software of upgrade-system carrying out system.
Above video signal source mainly is some preprepared audio-visual-materials.But, often also need some broadcasts such as live signals such as satellite-signal, other studio signals along with the TV news form is enriched constantly.Therefore, the utility model also provides an extraneous signal interface, can insert other extraneous signals.This extraneous signal interface is the same with above-mentioned each video signal source, under the control of instructor in broadcasting's central control board, exports its output signal to cut bank.
For the recording and broadcasting system of now TV news, the real time record of broadcasting signal in order to replaying or the later stage edits again, is absolutely necessary.Therefore, the utility model on the basis of said structure also design corresponding signal recording system is arranged.
As shown in Figure 2, also be provided with the signal recording system except that comprising shown in Fig. 1 the structure in this dynamic recording and broadcasting system, specifically include:
Signal recording unit
Signal recording unit gets off in order to vision signal and the audio signal recording that will be imported.Simultaneously, signal recording unit can also write down the time that the switching point state is taken place.
Time code generator
Time code generator generates a unified time sign indicating number, in order to vision signal and the audio signal that goes on record synchronously, can keep absolute synchronization in time to guarantee all signals.
Record central control board
Record central control board and be responsible for the centralized control of whole signal recording system, comprise each recording elements startup, stop and condition monitoring.
The input of signal recording unit links to each other with aforementioned shooting unit, video tape player, audio frequency sound console and extraneous signal interface, receives and write down the video/audio signal that these signal sources send.Signal recording unit also links to each other with cut bank, the broadcast vision signal of recording of video cut bank output.In addition, signal recording unit also links to each other with described GPIO repeater, position and time that the cut bank switching state that record is parsed by the GPIO repeater is taken place.
Time code generator links to each other with signal recording unit, and timing code is joined in the above-mentioned various signal that is recorded, with synchronous various signals.
Record central control board and link to each other with this signal recording unit, time code generator, control each recording elements startup, stop and condition monitoring.Simultaneously, recording central control board also controls by the instructor in broadcasting is unified by instructor in broadcasting's central control board.
By above-mentioned signal recording system, dynamic recording and broadcasting system of the present utility model can be noted various come source signal data and switching state information that the instructor in broadcasting did in record news, can conveniently replay or the later stage edits again.
