Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to fig. 1-4 and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The embodiment of the application discloses a method for monitoring abnormal state or degradation of a broadcasting server signal.
Referring to fig. 1, as an embodiment of a method of monitoring a playout server signal anomaly or degradation, a method of monitoring a playout server signal anomaly or degradation comprises the steps of:
step S101, acquiring a feature folder corresponding to a video program at the moment of broadcasting the video program. The feature folder is sequentially stored with first video image feature data of each frame of the video program.
Specifically, the first video image feature data may include one or more of a brightness feature, a color feature, a texture feature, a shape feature, and a spatial relationship feature, and the first video image feature data is stored in a feature folder in the form of a file. The file names of the first video image feature data may gradually increase according to the order of the frames, for example, the file name of the first video image feature data of the first frame is 0000000001, the file name of the first video image feature data of the second frame is 0000000010, the file name of the first video image feature data of the third frame is 0000000011, and so on, so that the first video image feature data of each frame of the video program is sequentially stored in the feature folder.
And S102, acquiring the video signal output by the broadcasting server in real time.
Step S103, feature extraction is carried out on the video signals frame by frame, and second video image feature data of each frame of the video signals are obtained in sequence.
Specifically, the video signal is a baseband video signal, and feature extraction can be performed without decoding. The second video image feature data may include one or more of a luminance feature, a color feature, a texture feature, a shape feature, and a spatial relationship feature, and the second video image feature data may be of the same kind as the first video image feature data.
Step S104, judging whether each frame of the video signal is aligned with the corresponding frame of the video program according to the arrangement sequence of the frames; if not, the step S105 is entered; if so, the process proceeds to step S106.
Specifically, whether each frame of the video signal is aligned with a corresponding frame of the video program can be determined through a frame alignment algorithm. Determining whether each frame of the video signal is aligned with a corresponding frame of the video program is performed in real time, for example, first determining whether a first frame of the video signal is aligned with a first frame of the video program.
And S105, sending first abnormal alarm information.
Specifically, if a certain frame of the video signal cannot be aligned with a corresponding frame of the video program, it directly indicates that the broadcasting server has a problem with software and hardware, and can be located to the position of the frame with the problem. The first abnormal alarm information can be sent to the display screen, the intelligent terminal and the controller used for controlling the work of the warning piece. The intelligent terminal includes, but is not limited to, a smart phone, a PAD, a laptop, and a desktop. The warning device includes but is not limited to a buzzer and a warning light.
And S106, performing difference analysis on the first video image characteristic data and the second video image characteristic data of the same frame to obtain quantitative scores of the first video image characteristic data and the second video image characteristic data.
Specifically, after a certain frame of the video signal is aligned with a corresponding frame of the video program, difference analysis is performed on first video image feature data and second video image feature data of the same frame. For example, after a first frame of the video signal and a first frame of the video program can be aligned, difference analysis is performed on first video image feature data of the first frame and second video image feature data of the first frame. The difference analysis may be to analyze one or more corresponding luminance features, color features, texture features, shape features, and spatial relationship features of the first video image feature data and the second video image feature data.
Step S107, judging whether the quantitative score is larger than a preset threshold value; if not, the process proceeds to step S108.
And S108, sending second abnormal alarm information.
In the method, when the video file is really broadcast, the video signal sent by the broadcast server is subjected to feature extraction in real time frame by frame to obtain second video image feature data, and alignment analysis and difference analysis are carried out on the second video image feature data and the first video image feature data of each frame of the video program stored in the feature folder in sequence, so that program faults caused by hardware or software faults of the broadcast server are effectively captured.

reading a broadcast program list;
associating corresponding feature folders according to the program list; and the number of the first and second groups,
and acquiring the feature folder.
Specifically, by reading the broadcast program list, the feature file folder of the video file to be broadcast can be directly associated according to the program broadcast sequence of the program list, so that the feature file folder corresponding to the video file does not need to be manually acquired.
As another embodiment of the method for monitoring the broadcasting server signal anomaly or degradation, the real-time acquisition of the video signal output by the broadcasting server includes the real-time acquisition of the video signal output by the main broadcasting server, or includes the real-time acquisition of the video signal output by the main broadcasting server and the real-time acquisition of the video signal output by the standby broadcasting server.
