Problems solved by technology
And once the broadcasting time of the first video data has passed, the broadcasting control unit will not send the broadcasting command to the first video data again, so as to be unable to control the broadcasting of the interrupt backup part video signal for the first video data
If the broadcasting time of the first video data is relatively long, there is no backup mechanism for the video signals broadcast during the continuous broadcasting period of the first video data, which is risky

Embodiment Construction
[0028] The core idea of the present invention is: during the playback process of the currently played video data, after the system failure recovers, calculate the insertion point of the currently played video data that should be played at present, and send a follow-up command to realize the current playback The video data interrupts the broadcast of the partial video signal.
[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.
[0030] Such as figure 2 Shown, a kind of follow-up method in broadcast control system, this method comprises the following steps:
[0031] Step 101. Obtain the current time corresponding to the currently played video data during the playing process after troubleshooting and recovery, and the start time of the currently played video data.
[0032] Step 102: Subtr...

The invention discloses a method for following broadcast in a broadcast controlling system, which comprises the following steps: subtracting the obtained broadcast launching time from the obtained current time; obtaining an inserting point of currently-broadcasted video data needing to be currently broadcasted through calculation; sending a broadcast following command in the obtained inserting point; and realizing the broadcast of a video signal of an interruption part aiming at the currently-broadcasted video data. The invention also discloses a device for following broadcast in the broadcast controlling system; and the device comprises an obtaining unit, a calculation unit and a broadcast realization unit, wherein the calculation unit is used for subtracting the obtained broadcast launching time from the current time, obtaining the inserting point of the currently-broadcasted video data needing to be currently broadcasted through calculation and sending information of the inserting point to the broadcast realization unit so as to realize the broadcast of the video signal of the interruption part. The method and the device are adopted and can broadcast the interrupted video signal in time when a single control and broadcast system having fault in the system repairs the fault and is recovered to a normal working state.
Description
technical field [0001] The invention relates to a broadcasting technology in a broadcasting control system, in particular to a method and device for following broadcasting in broadcasting by a video server of the broadcasting control system. Background technique [0002] At present, the broadcast control system used by TV stations when broadcasting video data generally includes: a video server and a broadcast control unit. Wherein, the video server is usually a video server of a TV station, and the information stored in it includes: a plurality of video data to be broadcast, which can also be referred to as a plurality of materials to be broadcast, and the video server is used to transfer The video data to be broadcasted is broadcasted. The information stored in the broadcast control unit includes: the start time of the video data to be broadcast, and the table of contents of the video data to be broadcast. Here, the identifier of the video data to be broadcast is stored i...
