Optionally, before step 101, this embodiment of the present invention further includes the following steps:

Step 201, acquire the program list of the current channel.

In the embodiment of the present invention, the program list of the current channel is obtained by sending a request for acquiring the program list of the current channel to the upstream software and receiving the program list returned by the upstream software. Wherein, the upstream software may be automatic broadcast software, and the upstream software may arrange program broadcast content to generate a program list corresponding to the channel. The content of the program list may include program name, program broadcast time, program broadcast duration, program signal type, program broadcast equipment and so on.

Step 202, according to the program list and the current time, determine the currently broadcast program of the current channel.

In the embodiment of the present invention, the currently broadcast program is the broadcast content corresponding to the current time channel, and the next broadcast program is the broadcast content to be played on the current channel after the current broadcast program finishes playing. Therefore, the currently broadcast program of the channel can be judged based on the program list according to the current time.

The specific judgment steps are as follows. If the current time is after the start time of the first program in the program list and before the start time of the second program, confirm that the program corresponding to the start time of the first program is the currently broadcast program, and the second program will start broadcasting. The program corresponding to the time is the next broadcast program, wherein, the start time of the second program is after the start time of the first program, and the start time of the second program is at the same time as the start time of the first program. The time difference in the list is the smallest. For example, in the program list of channel X, the broadcast time of program A is 7:00, and the broadcast time of program B is 7:40. If the current time is 7:20, it is determined that the currently broadcast program is program A, and the next broadcast program is program B.

Step 203: Determine the next broadcast program from the program list according to the current broadcast program, and obtain the program signal type of the next broadcast program to obtain the target signal type.

In the embodiment of the present invention, the next broadcast program corresponding to the currently broadcast program in the program list can be determined as the next broadcast program, and the program name corresponding to the next broadcast program can be obtained from the program list according to the program name of the next broadcast program. The program signal type corresponding to the name, which is the target signal type of the next broadcast program.

In the embodiment of the present invention, by obtaining the program list of the current channel and associating with the content of the program list, the current broadcast program, the next broadcast program and the next broadcast program can be automatically judged according to the content contained in the program list The program signal type, so as to determine the monitoring configuration file according to the program signal type, which simplifies the process of determining the monitoring configuration file to a certain extent.

Optionally, step 201 may include the following steps:

Step 2011, periodically obtain the program list of the current channel through the target interface according to the preset time interval.

In the embodiment of the present invention, in order to make the data of the program list more accurate, the local program list may be refreshed regularly. Specifically, through the interface with the upstream software, the program list acquisition request can be sent to the upstream software at preset time intervals, and after receiving the program list returned by the upstream software, the program list can be cached in the signal comparison system in server memory. Wherein, the preset time interval can be set as required, for example, the preset time interval can be 1 min, which is not limited in the embodiment of the present invention.

Correspondingly, step 202 may include:

Step 2012: Determine the currently broadcast program of the current channel according to the latest acquired program list and the current time.

Wherein, the program list acquired latest may be the program list stored in the memory of the server at the current time.

In the embodiment of the present invention, by periodically obtaining the program list, when the program list changes, the latest program list can be automatically and accurately obtained according to the newly acquired program list, and then the current broadcast program can be confirmed more accurately. program, so that the program signal type of the next broadcast program can be subsequently determined based on the currently broadcast program, ensuring the accuracy of judging the program signal type of the next broadcast program according to the program list.

Optionally, the next broadcast program corresponds to multiple program signals.

Among them, the program broadcast signal may include the main channel signal and one or more backup channel signals, and different signal types may correspond to different channel program signals. For example, when the signal type is a hard disk signal, the broadcast switcher corresponds to the connected The broadcast line includes the main channel signal, the backup channel signal and the third backup channel signal. When the signal type is a rebroadcast signal, the broadcast lines connected to the broadcast switcher include the main channel signal and the backup channel signal.

Step 102 may include the following steps:

Step 1021: Perform consistency comparison on the multi-channel program signals, and determine the parameter thresholds of the signal parameters to be detected defined in the target monitoring strategy.

In the embodiment of the present invention, by acquiring multiple program signals, the signal parameters of each program signal can be extracted, and the signal parameters of each frame of each program signal can be sequentially obtained, and the program signals of each channel can be consistent based on the signal parameters. sex comparison. Wherein, when the broadcast line includes two signals, the consistency comparison is the main and standby signal comparison, and when the broadcast line includes more than two signals, the consistency comparison is a pairwise cyclic comparison. The signal parameters may include image feature data and sound feature data, and the image feature data may specifically include one or more of brightness feature parameters, color feature parameters, texture feature parameters, shape feature parameters, and spatial relationship feature parameters. The extracted signal parameters are of the same kind. After extracting the characteristic parameters of each program signal, the parameter thresholds corresponding to different signals are determined based on the target monitoring strategy corresponding to the next broadcast program. Wherein, the parameter threshold can be set as required, which is not limited in this embodiment of the present invention.

Step 1022: Obtain in real time the signal parameters to be detected of each program signal corresponding to the next broadcast program.

In the embodiment of the present invention, each program signal corresponding to the next broadcast program is a broadcast line connected to the broadcast switcher corresponding to the program signal type of the next broadcast program. For example, if the next broadcast program If the signal type of the program is a hard disk signal, then obtain the signal parameters to be detected of the main channel signal, the backup channel signal, and the third backup channel signal; if the program signal type of the next broadcast program is a relay signal, then obtain Signal parameters to be detected for the signal. The signal parameters to be detected may include image feature data, specifically, one or more of brightness feature parameters, color feature parameters, texture feature parameters, shape feature parameters, and spatial relationship feature parameters.

Step 1023: Perform real-time anomaly monitoring on each program signal according to the parameter threshold and the acquired signal parameters to be detected.

In the embodiment of the present invention, in the process of real-time anomaly monitoring for each signal, if any parameter of the signal to be detected in a signal is greater than or equal to the parameter threshold corresponding to the parameter of the signal to be detected, it is confirmed that the signal of the channel is present. Abnormal. For example, when it is detected that the brightness characteristic parameter in the main channel signal is greater than the parameter threshold corresponding to the brightness characteristic parameter, it indicates that the main channel signal has an abnormal state.

In the embodiment of the present invention, by performing real-time anomaly monitoring on multi-channel program signals at the same time, the abnormal conditions of each channel program signal can be effectively captured, so that line switching can be performed according to the conditions of each channel signal, and by obtaining the multi-channel program signal Signal parameters, combined with parameter thresholds for real-time anomaly monitoring, can detect abnormalities in various program signals in time, so as to facilitate timely processing, thereby ensuring normal broadcasting of programs and avoiding broadcasting accidents.

Optionally, in the case where the target signal type is a rebroadcast signal, the step 103 includes the following steps:

Step 301 , if it is only detected that the main channel program signal of the next broadcast program is abnormal, switch the main channel program signal to the first backup channel program signal.

In the embodiment of the present invention, when the target signal type is a rebroadcast signal, the broadcast line corresponding to the access of the broadcast switcher is two signals, that is, the main channel signal and the backup channel signal, so the corresponding monitoring configuration file represents The switching strategy can be: in the case that only the main channel program signal is abnormal, it indicates that the main channel program signal is no longer suitable for playing programs as output signals, and can switch to the first backup channel program signal. Wherein, the first backup channel program signal may be the backup channel signal in the broadcast line correspondingly connected to the above-mentioned broadcast switcher.

In the case that the program signal of the next broadcast program is detected to be abnormal, the line signal is switched according to the switching strategy corresponding to the target signal type of the next broadcast program, so as to ensure the normal broadcast of the program.

Step 302: If it is detected that both the main channel program signal of the next broadcast program and the first backup channel program signal are abnormal, switch the main channel program signal to the program signal of the designated program.

In the embodiment of the present invention, since the rebroadcast signal is an external signal that is connected, the broadcast lines corresponding to the access of the broadcast switcher are only the main channel signal and the backup channel signal, and the main channel signal and the backup channel signal are abnormal In some cases, it indicates that the main channel program signal and the backup channel signal are no longer suitable for playing programs as output signals. In order to ensure uninterrupted playback, the main channel program signal is switched to the program signal of the designated program. It is a pad signal, or it can be a pre-set commercial that can be inserted at any time, or other short videos that can be inserted into any program at any time. The shim signal is the output signal corresponding to the shim program played by default in emergency. It is generally used as the line signal for emergency output in order to ensure that the playback is not interrupted when the main and backup lines fail at the same time.

Optionally, after monitoring that the main channel program signal of the next broadcast program is abnormal, and switching the main channel program signal to the first backup channel program signal, continue to perform abnormal state on the main channel signal and the first backup channel program signal. State monitoring, in the case of an abnormality in the program signal of the first backup channel, if the program signal of the main channel is normal, that is, there is no abnormality, the program signal of the first backup channel will be switched to the program signal of the main channel; if the program signal of the main channel If an abnormal state occurs, switch the program signal of the main channel to the program signal of the specified program.

In the embodiment of the present invention, when the target signal type is a rebroadcast signal, according to the monitoring strategy corresponding to the rebroadcast signal, in the case of an abnormality in the line, the line is switched in time according to the monitoring strategy to ensure the normal broadcast of the program . At the same time, in the case that both the main and backup channel signals of the program are abnormal, by switching the signal to the program signal of the specified program, the broadcast accident caused by the interruption of program playback can be avoided.

Optionally, in the case where the target signal type is a hard disk signal or a VTR signal, the step 103 may also include the following steps:

Step 401 , if it is only detected that the main channel program signal of the next broadcast program is abnormal, switch the main channel program signal to the first backup channel program signal.

In the embodiment of the present invention, when the type of the target signal is a hard disk signal or a VTR signal, the corresponding broadcast lines connected to the broadcast switcher are three-way signals, namely the main line signal, the backup line signal and the third backup line signal , so the switching strategy represented by the corresponding monitoring configuration file can be: in the case of an abnormality in the main channel program signal, it indicates that the main channel program signal is no longer suitable for playing programs as an output signal, and can be switched to the first backup channel program signal.

In the case that the program signal of the next broadcast program is detected to be abnormal, the line signal is switched according to the switching strategy corresponding to the target signal type of the next broadcast program, so as to ensure the normal broadcast of the program.

Step 402: If it is detected that both the main channel program signal of the next broadcast program and the first backup channel program signal are abnormal, switch the main channel program signal to a second backup channel program signal.

In the embodiment of the present invention, when the main channel program signal and the first backup channel program signal are abnormal, it indicates that the main channel program signal and the first backup channel program signal are no longer suitable for playing programs as output signals, and the main channel The program signal is switched to the program signal of the second standby channel. Wherein, the second backup channel program signal may be the third backup channel signal in the broadcast line correspondingly connected to the above-mentioned broadcast switcher.

Step 403: If it is detected that the program signal of the main channel, the program signal of the first backup channel, and the program signal of the second backup channel of the next broadcast program are abnormal, switch the program signal of the main channel is the program signal of the specified program.

In the embodiment of the present invention, when all the signals of the three channels are abnormal, that is, the program signal of the main channel, the program signal of the first backup channel, and the program signal of the second backup channel are all abnormal, in order to ensure that the playback is not interrupted, then Switch the program signal of the main channel to the program signal of the specified program.

Optionally, after monitoring that the main channel program signal of the next broadcast program is abnormal, and switching the main channel program signal to the first backup channel program signal, continue to perform abnormal state on the main channel signal and the first backup channel program signal. State monitoring, in the case of an abnormality in the program signal of the first backup channel, if the program signal of the main channel is normal, that is, there is no abnormality, the program signal of the first backup channel will be switched to the program signal of the main channel; if the program signal of the main channel If there is an abnormal state and the program signal of the second backup channel is normal, switch the program signal of the main channel to the program signal of the second backup channel; if the program signal of the main channel, the program signal of the first backup channel and the program signal of the second backup channel all appear abnormal , the main channel program signal is switched to the program signal of the specified program.

In the embodiment of the present invention, when the target signal type is a hard disk signal or a VTR signal, the broadcast line corresponding to the access of the broadcast switcher is a three-way signal. In the case of an abnormal state, it can switch to the program signal of the first backup channel or the program signal of the second backup channel as the output signal to continue playing the program, so as to achieve the effect of switching the line in time according to the monitoring strategy and ensuring the normal broadcasting of the program. At the same time, in the case that both the main and backup channel signals of the program are abnormal, by switching the signal to the program signal of the specified program, the broadcast accident caused by the interruption of program playback can be avoided.
