Description of drawings
Fig. 1 is the changing method flow chart of a kind of many switching devices of the embodiment of the present invention;
Fig. 2 is a kind of equipment connection schematic diagram that the method for the embodiment of the present invention adopts.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, the changing method of many switching devices of the present invention comprises:
Step S101a is according to the facility information of input, the logical relation information between each equipment of system diagram and signal acquisition.Facility information (attribute that comprises equipment), system diagram and signal can be by the good configuration file typings of configured in advance, also can on-the-spot typing.Wherein, system diagram has provided actual equipment connection situation, as shown in Figure 2, be simple equipment connection schematic diagram in the studio: the capital equipment of existence has: video input apparatus, frame synchronization integrated circuit board, video matrix, video delayer, video distribution integrated circuit board and picture output device (actual conditions are not limited to this several equipment, as: also comprise not shown Video processing integrated circuit board etc.).
This step specifically comprises: by signal source, signal is processed with equipment, and signal switches and four kinds of attribute types of signal target are divided; Each equipment is imparted into the outbound port attribute, and annexation man-to-man according to each port establishes a connection all devices according to the connected mode in system diagram; Obtain the signal format that each enters outbound port, as high-definition signal, SD signal etc., or can replace with the various concrete form of high/standard definition signal.According to facility information, system diagram and signal can obtain following link information about equipment, and video input apparatus connects video matrix (being used for signal switches) with signal, if needed, video matrix is sent back after encircling out video processing equipment again.At last, send into picture output device by video matrix.
After with the armamentarium input information, as add a programme, only need simple selection source, purpose and time get final product.System determines whether through special processing according to concrete signal input type, then delivers on corresponding purpose signal output channel.
The attribute type of recording equipment, annexation and signal format, thus logical relation information obtained.
Preferably, also the form of logical relation information with file recorded and store after obtaining logical relation information.Can adopt the form of database table to record logical relation information, and store with database file.
Step S101b reads program scheduling information from the program scheduling list.
Step S102 calculates signal link according to logical relation information and the program scheduling information obtained in advance.Specifically comprise: according to the title of the signal source in program scheduling information and signal target, parse required signal source equipment and signal target equipment; According to the signal format of signal source equipment and the signal format of signal target equipment, select required signal handling equipment.
Use is with comprising signal source equipment, and signal target equipment and time started, the program scheduling information of concluding time according to above-mentioned logical relation information, is used or the signal link of flowing through calculates each program, generates signal link.Preferably, signal link records and stores with the form of chained list.For example:
The program scheduling list that broadcasts is as follows:
Source-studio 1, purpose-7 channel broadcasts, time started-0930, concluding time-1030;
Source-studio 2, purpose-6 channel broadcasts, time started-1130, concluding time-1230;
Source-studio 3, purpose-5 channel broadcasts, time started-1330, concluding time-1430;
Equipment comprises video input apparatus (a plurality of), frame synchronization integrated circuit board (a plurality of), video distribution integrated circuit board (a plurality of), delayer (a plurality of), matrix (a plurality of), video input apparatus (a plurality of).
System is according to the entry time and the source that obtain, and the next stage that the logical relation that obtains by step S102 and required signal handling equipment obtain the source by that analogy, obtains the crosspoint of whole signal path on video matrix (video switching apparatus).As: the vision signal of source-studio 1 has been connected on the entrance 1 of video matrix, picture output device has been connected in the outlet 1 of video matrix, but vision signal need to just can be delivered to the signal outlet business through the processing of frame synchronization integrated circuit board, and the frame synchronization integrated circuit board has connected entrance 3 and the outlet 3 of matrix.So by controlling video matrix, entrance 1 is switched in outlet 3 makes video input apparatus be connected with the frame synchronization integrated circuit board, by controlling video matrix, entrance 3 is switched in outlet 1 again, the output of frame synchronization integrated circuit board is connected with picture output device, has so just formed a bars link: video input apparatus-frame synchronization integrated circuit board-picture output device.Entrance 1 is to outlet 3, and entrance 3 switches action to the crosspoint that outlet 1 is video matrix.For another example: the vision signal of source-studio 2 is configured to the SD signal according to input configuration, and 6 channel broadcasting signals are configured to high-definition signal according to input configuration, system can select idle Video processing integrated circuit board equipment to carry out SD to the conversion of high definition automatically, thereby form available transmission of video link, also comprised Video processing integrated circuit board equipment in the signal link of this moment.
Step S103 at program scheduling information discal patch purpose point switching time, carries out signal according to signal link to relevant device and switches.Preferably, switching time, point was set to the time point of Pre-handoff, so that the user examines the result of switching in advance, had guaranteed Security of the system.This step comprises that also a finishing switching is set moves.
Step S104, when program entries finishes, system will carry out this finishing switching action, be used for default location is recovered to be placed in the crosspoint of signal switching apparatus.After an entry switching was completed, system was calculated according to the current time automatically, obtains the next entry that need to switch, and carried out the S102 action on time, thereby back and forth constantly.
Method of the present invention can be broadcasted turn-key system based on each and carry out flexible configuration, automatically carries out many equipment schedulings according to given program list and signal type.Greatly save time and can improve operating efficiency.
Above execution mode only is used for explanation the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
