Therefore, the current broadcast program of the channel can be judged based on the program list according to the current time.
The specific determination step includes that under the condition that the current time is after the first program playing time and before the second program playing time in the program list, the program corresponding to the first program playing time is determined to be the current broadcast program, and the program corresponding to the second program playing time is determined to be the next broadcast program, wherein the second program playing time is after the first program playing time, and the time difference between the second program playing time and the first program playing time in the program list is the minimum. For example, in the program list of channel X, the broadcast time of program a is 7. And if the current time is 7.
Step 203, determining the next broadcast program from the program list according to the current broadcast program, and obtaining 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 current broadcast program in the program list may be determined as the next broadcast program, and according to the program name of the next broadcast program, the program signal type corresponding to the program name is obtained from the program list, where the signal type is the target signal type of the next broadcast program.

Optionally, step 201 may include the following steps:
and 2011, periodically acquiring the program list of the current channel through the target interface according to a preset time interval.
In the embodiment of the invention, in order to make the data of the program list more accurate, the local program list can be refreshed at regular time. Specifically, a program acquisition request may be sent to the upstream software at a preset time interval through an interface with the upstream software, and after receiving a program returned by the upstream software, the program is cached in a server memory of the signal comparison system. The preset time interval may be set according to needs, for example, the preset time interval may be 1min, and this is not limited in the embodiment of the present invention.
Accordingly, step 202 may include:
step 2012, determining the current broadcast program of the current channel according to the latest acquired program list and the current time.
The program list acquired last time may be a program list stored in the memory of the server at the current time.
In the embodiment of the invention, the current latest program list can be automatically and accurately obtained according to the latest obtained program list by periodically obtaining the program list when the program list is changed, so that the current broadcast program can be more accurately identified, the program signal type of the next broadcast program can be determined based on the current broadcast program, and the accuracy of judging the program signal type of the next broadcast program according to the program list is ensured.
Optionally, the next broadcast program corresponds to multiple program signals.
For example, when the signal type is a hard disk signal, the broadcast line correspondingly accessed by the broadcast switcher includes a main path signal, a standby path signal and a third standby path signal. When the signal type is a rebroadcast signal, the broadcasting lines correspondingly accessed by the broadcasting switcher comprise main path signals and standby path signals.
Step 102 may include the steps of:
step 1021, comparing the consistency of the multi-channel program signals, and determining a parameter threshold of a to-be-detected signal parameter defined in the target monitoring strategy.
In the embodiment of the invention, the signal parameter extraction can be carried out on each channel of program signals by obtaining the multiple channels of program signals, the signal parameter of each frame of each channel of program signals is sequentially obtained, and the consistency comparison is carried out on each channel of program signals based on the signal parameter. When the broadcasting line comprises two paths of signals, the consistency comparison is the comparison of the main signals and the standby signals, and when the broadcasting line comprises more than two paths of signals, the consistency comparison is the comparison of pairwise circulation. The signal parameters may include image feature data and sound feature data, the image feature data may specifically include one or more of a brightness feature parameter, a color feature parameter, a texture feature parameter, a shape feature parameter, and a spatial relationship feature parameter, and the types of the signal parameters extracted from the program signals of the respective channels are the same. After extracting the characteristic parameters of each path of program signal, determining the parameter threshold values corresponding to different signals based on the target monitoring strategy corresponding to the next broadcast program. The parameter threshold may be set according to needs, and the embodiment of the present invention is not limited to this.
And 1022, acquiring a signal parameter to be detected of each path of program signal corresponding to the next broadcast program in real time.
In the embodiment of the present invention, each path of program signal corresponding to the next broadcast program is a broadcast line to which the broadcast switcher corresponding to the program signal type of the next broadcast program is connected, for example, if the program signal type of the next broadcast program is a hard disk signal, the signal parameters to be detected of the main path signal, the standby path signal, and the third standby path signal are obtained; and if the program signal type of the next broadcast program is a rebroadcast signal, acquiring the signal parameters to be detected of the main path signal and the standby path signal. The signal parameter to be detected may include image feature data, and specifically may include one or more of a luminance feature parameter, a color feature parameter, a texture feature parameter, a shape feature parameter, and a spatial relationship feature parameter.
And 1023, performing real-time abnormal state monitoring on each path of program signals according to the parameter threshold and the acquired parameters of the signals to be detected.
In the embodiment of the invention, in the process of monitoring the abnormal state of each path of signal in real time, under the condition that any signal parameter to be detected of one path of signal is greater than or equal to the parameter threshold value corresponding to the signal parameter to be detected, the abnormal state of the path of signal is confirmed. For example, when it is monitored that the brightness characteristic parameter in the main path signal is greater than the parameter threshold corresponding to the brightness characteristic parameter, it is indicated that the main path signal is in an abnormal state.
In the embodiment of the invention, the abnormal condition of each program signal can be effectively captured by simultaneously monitoring the multiple program signals in real time, so that the line switching can be conveniently carried out according to the condition of each signal, and the abnormal condition of each program signal can be timely monitored by acquiring the signal parameters of the multiple program signals and combining the parameter threshold value for real-time abnormal monitoring, so that the abnormal condition of each program signal can be timely monitored, the processing can be timely carried out, the normal broadcasting of the program can be ensured, and the occurrence of broadcasting accidents can be avoided.
Optionally, in a case that the target signal type is a rebroadcast signal, the step 103 includes the following steps:
step 301, if it is only monitored that the main path program signal of the next broadcast program is abnormal, the main path program signal is converted into a first standby path program signal.
In the embodiment of the present invention, when the type of the target signal is a rebroadcast signal, the corresponding broadcast line of the broadcast switcher is two paths of signals, that is, a main path signal and a standby path signal, so the switching strategy represented by the corresponding monitoring configuration file may be: when only the main program signal is monitored to be abnormal, the main program signal is indicated to be no longer suitable for being used as an output signal to play the program, and the first standby program signal can be switched. The first standby channel program signal may be a standby channel signal in a broadcasting channel correspondingly accessed by the broadcasting switcher.
Under the condition that the abnormal state of the program signal of the next broadcast program is monitored, 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 monitored that the main path program signal and the first standby path program signal of the next broadcast program are in different states, the main path program signal is converted into a program signal of a specified program.
In the embodiment of the invention, because the rebroadcast signal is an accessed external signal, the corresponding accessed broadcast line of the broadcast switcher only has a main path signal and a standby path signal, and when the main path signal and the standby path signal are in different states, the main path program signal and the standby path signal are indicated to be not suitable for being used as output signals to broadcast programs, and in order to ensure that the broadcasting is not interrupted, the main path program signal is switched into a program signal of a specified program, wherein the program signal of the specified program can be a spacer signal, or a preset advertisement which can be inserted at any time or other small-segment video which can be inserted into any program at any time. The shim signal is an output signal corresponding to a shim program which is played by emergency default, and is generally used for line signals which are output by emergency in order to ensure uninterrupted playing under the condition that the main and standby lines simultaneously fail.
Optionally, after the main path program signal of the next broadcast program is monitored to be in an abnormal state, the main path program signal is switched to the first standby path program signal, and then the abnormal state monitoring is continuously performed on the main path signal and the first standby path program signal; if the main program signal is abnormal, the main program signal is switched to the program signal of the designated program.
In the embodiment of the invention, under the condition that the type of the target signal is the rebroadcast signal, the line is switched in time according to the monitoring strategy under the condition that the line is abnormal according to the monitoring strategy corresponding to the rebroadcast signal, so that the normal broadcasting of the program is ensured. Meanwhile, under the condition that the main and standby program signals are all abnormal, the signals are switched into the program signals of the designated program, so that the broadcasting accidents caused by the interruption of program broadcasting can be avoided.
Optionally, in the case that the target signal type is a hard disk signal or a VTR signal, the step 103 may further include the following steps:
step 401, if it is only monitored that the main path program signal of the next broadcast program is abnormal, the main path program signal is converted into a first standby path 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 broadcasting line to which the broadcasting switcher is correspondingly connected is three signals, that is, a main signal, a standby signal, and a third standby signal, so that the switching policy characterized by the corresponding monitoring configuration file may be: when the main path program signal is abnormal, the main path program signal is no longer suitable for playing programs as an output signal, and the first standby path program signal can be switched.
Under the condition 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 monitored that the main path program signal and the first standby path program signal of the next broadcast program are abnormal, the main path program signal is converted into a second standby path program signal.
In the embodiment of the present invention, when the main path program signal and the first standby path program signal are in an abnormal state, it indicates that both the main path program signal and the first standby path program signal are no longer suitable for playing a program as output signals, and the main path program signal is converted into the second standby path program signal. The second standby channel program signal may be a third standby channel signal in a broadcasting channel correspondingly accessed by the broadcasting switcher.
Step 403, if it is monitored that the main path program signal, the first standby path program signal and the second standby path program signal of the next broadcast program are all abnormal, the main path program signal is converted into the program signal of the specified program.
In the embodiment of the invention, under the condition that the three paths of signals have different states, namely the main path program signal, the first standby path program signal and the second standby path program signal have different states, in order to ensure that the playing is not interrupted, the main path program signal is switched to the program signal of the specified program.
Optionally, after the main path program signal of the next broadcast program is monitored to be in an abnormal state, the main path program signal is switched to the first standby path program signal, and then the abnormal state monitoring is continuously performed on the main path signal and the first standby path program signal; if the main path program signal is abnormal and the second standby path program signal is normal, the main path program signal is converted into the second standby path program signal; if the main path program signal, the first standby path program signal and the second standby path program signal are all abnormal, the main path program signal is switched to the program signal of the designated program.
In the embodiment of the invention, under the condition that the target signal type is a hard disk signal or a VTR signal, the broadcasting line correspondingly accessed by the broadcasting switcher is a three-way signal, and aiming at a monitoring strategy corresponding to the condition of the three-way signal, under the condition that the line is abnormal, the broadcasting switcher can be switched to a first standby program signal or a second standby program signal to serve as an output signal to continue to broadcast programs, so that the effect of timely switching the line according to the monitoring strategy and ensuring the normal broadcasting of the programs is achieved. Meanwhile, under the condition that the main and standby program signals are all abnormal, broadcasting accidents caused by program broadcasting interruption can be avoided by switching the signals into the program signals of the specified program.
