The studio multi-camera recording system can comprises a controlling unit and a plurality of recording units, wherein, the video of each camera can be recorded through the recording units, and the recorded file format is a unique video format; the starting and the stopping of the signal recording of the recording units can be controlled through the controlling unit at the same time, and the system also can record the switching position of the switching table to the programs to form an EDL edit decision list; and then the non-ideal switching points can be remedied only through simple change to the switching points, and the wonderful pictures are retained, so that the program achieves the ideal effect finally, and the program quality is improved.
Description
Technical field
The present invention relates generally to the multi-position recording system of vision studio in the radio and television, more specifically relates to the multi-position recording system of vision studio of realizing based on software.
Background technology
What multi-position recording system of vision studio was mainly used in studio multimachine digital video records and records deutomerite purpose edit-modify.Can record by the program that studio system is taken the multimachine position, and can will note, create the system that provides advanced for program once more the program recording switching position.
During record existing multimachine position,, finally use cut bank to switch and form one tunnel vision signal, finish the making of program by the instructor in broadcasting by a plurality of seats in the plane floor picture from different perspectives.In this process, the excellence that the instructor in broadcasting directly affects final program to the scheduling of on-the-spot seat in the plane and control whether, although high-caliber instructor in broadcasting, it is still inevitable to guarantee to a great extent that the quality of final program, excellent camera lens are leaked the phenomenon of cutting.The final program that forms can't be revised the position of switching point, often needs to add the video tape recorder of respective numbers if write down each road video, and not only cost is than higher, and the video of recording need be uploaded and can be edited.
If using video tape records, the time span of recording has only 120 minutes, time span is very limited, and record the link that needs to upload after finishing and just can carry out non-linear editing by material, if use DVR to record, also there is the problem of compatible and popularity in the form of recorded file.So traditional multimachine position recording system exists many defectives and needs improved place.
Summary of the invention
The objective of the invention is to overcome the various defectives that record multimachine position, existing studio, a kind of multi-position recording system of vision studio of mainly realizing based on software is provided.
The objective of the invention is to be achieved through the following technical solutions:
A kind of multi-position recording system of vision studio, system is divided into two parts: be respectively control unit and recording elements.Control unit is by the GPIO card, and a computer constitutes.Carry out information communication by GPIO card and cut bank.Control unit then adopts records the positional information that Control Software can write down the cut bank switching, can control the start-stop of recording elements signal recording simultaneously.Recording elements is by computer and look audio frequency I/O card and form, and finishes recording, exporting of corresponding seat in the plane video-audio program by recording software.
Wherein, the described Control Software of recording can be controlled many recording elements simultaneously and carries out recording of material, in described recording process, carry out many recording elements if desired and begin the operation of recording simultaneously, start described while recording function, the described Control Software of recording is controlled many recording elements simultaneously by ICP/IP protocol and is begun simultaneously to record, and simultaneity factor shows the duration of recording in the mode that is accurate to frame.The multichannel material of recording can be strict each frame alignment, each frame all has absolute time code.
Wherein, the described information of recording all right register system of Control Software and cut bank switching, system is by the communication of GPIO card and cut bank in described recording process, position and information that the recording user operation cut bank is switched recording signal, and can register system record initial, stop, information such as output.
Wherein, described recording when Control Software can also start multiple signals supervised in advance, and the state that switches for cut bank will show at monitor window in the mode of TAILY warning light.
Wherein, the described Control Software of recording can also show the progress of output material in the mode of progress bar, made things convenient for supervising of user.
Wherein, the described Control Software of recording can also be with handover information output the becoming EDL edit decision list of record, if desired the switching point of program recording is made amendment, can in software for editing, directly open this table, just can directly see the position of switching, and can make amendment the position of switching.
Wherein, describedly record the switching state that Control Software can also show that cut bank is present, when cut bank switches recording signal, will point out, can see the state that cut bank switches at present at the window that supervision is recorded in the mode of TAILY warning light.
Wherein, describedly record the output after material is recorded carried out that Control Software can be controlled many recording elements simultaneously, in described recording process, carry out the output of recorded material if desired, start described beginning output function, described many recording elements of Control Software may command of recording begin the output of material simultaneously, and the state of material output simultaneously will show in the mode of progress bar.
Wherein, described recording elements record software, described recording function can become this road signal recording the distinctive audio format of looking, Yi Bian this form can realize recording, Yi Bian the function of output.Can carry out the output of material in real time, system can support the output of multiple material form.
Wherein, described recording elements record software, described recording function can become this road signal recording two kinds of forms of height two-way code stream, and the two-way code stream will realize " zero frame alignment ", is the low code stream editor, the high code stream material shines upon provides convenience.
Wherein, described recording elements record software, described recording function can carry out recording of multiple resolution video material, for example supports multiple resolution formats such as 1920 * 1080,720 * 576,192 * 192.
Because the present invention adopts related software realization studio to record on computers, so its cost is greatly diminished; In addition, special format, for the user provides working method more efficiently, it has not only simplified material from being recorded to the flow process of use greatly while gathering the function of exporting, and for example deadlock, sudden power etc. unsafe situation appearred, in the equipment that ought record, the file of recording can not be damaged, and can use normally.Distinctive recorded file form has improved the confidentiality and the fail safe of material for the user provides higher fail safe.
