System and method for evaluating real-time consistency of programs at multiple monitoring points in broadcast link

Abstract

The invention discloses a system and method for evaluating real-time consistency of programs at multiple monitoring points in a broadcast link, and the system comprises a program collection module, aprogram consistency evaluation module, a program abnormity analysis module, and an alarm logic processing module. The method comprises the steps: carrying out the coding of program signals of at leasttwo monitoring points on the broadcast link, and outputting program coding data; performing real-time consistency evaluation on the same program on different playing links to obtain a program consistency quantitative evaluation result of each monitoring point; performing frame-by-frame real-time heteromorphism analysis and detection on the program to obtain a program frame-by-frame heteromorphismassessment result; and according to the consistency quantitative evaluation result and the real-time abnormal state evaluation result, carrying out comprehensive judgment, analyzing whether a programabnormal state is really generated or not, and carrying out corresponding actions. According to the invention, real-time consistency evaluation and frame-by-frame abnormal degree evaluation results are integrated to determine whether abnormal states exist or not, so that the probability of false alarm is reduced, and the alarm accuracy and timeliness are improved.

Description

Technical field [0001] The invention relates to the technical field of program broadcasting, in particular to a real-time consistency evaluation system and method for programs at multiple monitoring points in a broadcasting link. Background technique [0002] At present, TV stations will pre-examine the pre-broadcast programs when the programs are uploaded. For specific content such as black pictures, still pictures, and silent pictures in the program content, such as black pictures when movie scenes are switched for a long time, and pictures played in news broadcasts The static pictures of the information for a long time, etc., are part of the broadcast program content, and the special person will enter the broadcast program after confirming the recording, and discard the playback software that has black pictures, still pictures, and silent pictures that are not the program content; At the same time, in the program broadcast link of the TV station, the monitoring system of each ...

Problems solved by technology

[0002] At present, TV stations will pre-screen pre-broadcast programs when uploading programs. For specific content such as black pictures, still pictures, and silent pictures in the program content, such as black pictures that have been switched for a long time in movie scenes, and pictures played in news broadcasts The pictures that are static for a long period of time are part of the content of the broadcast program. After being confirmed and recorded by a special person, they will enter the broadcast program, and the playback software with black screens, still pictures, and silent pictures that are not program content will be discarded; At the same time, in the program broadcast link of the TV station, the monitoring system of each link works independently, analyzes the content of the broadcast program in real time, and gives an alarm if there is any abnormal content such as black screen, static screen, and no sound in the broadcast program; at this time The monitoring system will regard the specific content in the broadcast program as an abnormality and send an alarm, which will cause false alarms. In order to reduce such false alarms, the current monitoring system of TV stations all adopts the method of setting time thresholds, and only the abnormal screen How many seconds did it last before it was judged as abnormal and started to report. This method can only reduce the amount of false positives to a certain extent, but at the same time it brings new problems. An alarm will be issued. At this time, the abnormal picture has been broadcast, which has caused a certain impact, or even a major broadcast accident.
