TV station's broadcasting line is the final outlet of TV programme.Generally, there are several channels in a TV station, and each channel has independently playing device.The stability of the correctness of content of TV program, accuracy and playing device is that TV station broadcasts the problem that department pays close attention to the most.In case break down, will directly cause the broadcast accident, bring bad social effect.
TV station's broadcast control system adopts unattended automatically working pattern at present, application demand according to the broadcasting line film titler, broadcasting line caption producing flow process by distributed network automatically, broadcast making and the audit of captions in channel side, and driving core volume unit generates caption broadcasting list automatically, then submit to automatically to be sent to and broadcast on the film titler, carry out the automatic broadcast of captions.
Because the program of most of TV station is all displayed by screens, generally be that the program of every day to the second day is very close to each other, perhaps the gap is very short.After the broadcasting list of today finished, also wanting manual switchover was the broadcasting list of tomorrow.In order to realize the unattended operation of broadcast control system, just need the automatic switchover of the broadcasting list of every day to the second day; For the broadcast monoenergetic of revising is broadcasted in real time, just need the automatic loading of broadcasting list to refresh.
Summary of the invention
The objective of the invention is at the unattended mode of operation of TV station's broadcast control system, a kind of method that automaticallyes switch and load refreshing broadcasting list is provided, to realize the real automation of Broadcast Control, guarantee continuity and fail safe that program broadcasts.
Technical scheme of the present invention is as follows: a kind of method that automaticallyes switch and load refreshing broadcasting list, this method is made into a broadcasting list file with the broadcasting list of every day, send under the broadcast file of broadcast control system, the broadcasting server of broadcast control system broadcasts the broadcasting list file, in turn each broadcasting list file is switched loading according to the time switching point that arranges; Simultaneously, broadcast control system carries out timing scan to broadcasting file, and when finding that the broadcasting list that is broadcasting has been modified, broadcast control system reloads and refreshes this broadcasting list.
Further, the method for aforesaid automatic switchover and loading refreshing broadcasting list, wherein, described broadcasting list file is the XML form, comprises content, broadcast time and the length of each bar captions in the broadcasting list file.
Further, the method for aforesaid automatic switchover and loading refreshing broadcasting list, wherein, described broadcasting list file is according to channel designation and broadcast the filename that the date constitutes broadcasting list, distinguishes according to the priority on date.
Further, the method of aforesaid automatic switchover and loading refreshing broadcasting list, wherein, when broadcast control system carries out timing scan to broadcasting file, just the current broadcasting list file that is broadcasting is carried out scan operation, and only the part of also not broadcasting in the current broadcasting list file is scanned.
Beneficial effect of the present invention is as follows: the present invention is undertaken alternately by file between caption editing software and broadcast control system, by being set, the time switching point realizes the automatic switchover of broadcasting list file every day, if the current time equals the time during switching point, broadcast control system can load next broadcasting list automatically and broadcast by the time, has realized the real automation of Broadcast Control; Broadcast control system broadcasts file by a clock thread scanning, refresh when monitoring to load after broadcasting list changes, for the clauses and subclauses of broadcasting, because when these clauses and subclauses began to broadcast, broadcast control system had just been issued broadcasting server to order, so, after broadcasting list changes loading renewal automatically, the clauses and subclauses of broadcasting are unaffected, the normal broadcast, and this has guaranteed fail safe and the continuity broadcasted.
Description of drawings
Fig. 1 is method schematic diagram of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in detail.
The precondition that the present invention realizes is that caption editing software and broadcast control system are undertaken alternately by file, that is to say that the broadcasting list that edits sends to the broadcast file of appointment in the mode of file, broadcasts then.Broadcast control system can monitor the situation of change of broadcasting file.File can be specified arbitrarily, and it is a place of depositing broadcasting list, makes things convenient for Broadcast Control software monitors and scanning.The form of broadcasting list file can have multiple, selects the XML form in the present embodiment for use, comprises content, broadcast time and the length etc. of each bar captions in the broadcasting list file.The broadcasting list file is according to channel designation and broadcast the filename that the date constitutes broadcasting list, distinguishes according to the priority on date.
The automatic switchover of carrying out broadcasting list must be known the broadcast time section of broadcasting list every day, and this time period is constant, for example: 03:00:00-27:00:00, the expression broadcasting list begins to broadcast from 3:00 AM, until second day 3:00 AM, this is one day broadcast time, and we claim that 27:00:00 is switching point H, if the current time, then broadcast control system can load next Zhang Danzi (second day list) automatically when equaling switching point H.That is to say that after the list of today finished, second day list was found in the Broadcast Control meeting, after finding, will load automatically and broadcast by the time, thereby realized the unattended operation of Broadcast Control.For example, after the broadcasting list of 2008-11-26 finishes, the broadcasting list of meeting automatic scan 2008-11-27.
List when some day broadcasts, but the captions of certain program that does not also broadcast will adjust, and the caption editing personnel can directly make amendment to the list of this day so, send to the broadcast file after having revised.The present invention includes a monitor scans file module, broadcast file by clock thread timing scan, can the disposing at interval of scanning, if ask real-time high, blanking time is just short.When broadcast control system carries out timing scan to broadcasting file, just the current broadcasting list file that is broadcasting is carried out scan operation, and only the part of also not broadcasting in the current broadcasting list file is scanned.When finding to have broadcasting list to revise, broadcast control system can reload this broadcasting list, does not influence the program that is broadcasting.
After monitoring that broadcasting list changes, for the clauses and subclauses of broadcasting, because when these clauses and subclauses begin to broadcast, just in the broadcasting list file all the elements under should clauses and subclauses having been issued broadcasting server, broadcasting server only broadcasts at the content of having received broadcast control system, so, after broadcasting list changes loading renewal automatically, the clauses and subclauses of broadcasting are unaffected, the normal broadcast, and this has guaranteed fail safe and the continuity broadcasted.
