Research shows that in order to ensure normal broadcasting of television programs, a broadcasting mechanism generally monitors a video playing picture in the video playing process, and monitors and alarms when the playing state of the television programs is in abnormal broadcasting states such as black screen, static picture, no accompanying sound and the like. Due to the requirements of equipment maintenance, updating and the like, a part of television programs stop broadcasting formal programs in a specific time period, and a situation that a stop-broadcasting picture and background music are replaced exists, however, the stop-broadcasting picture of the part of programs has moving areas such as a walking clock, a small-window video and the like, and the start-stop moment of the stop-broadcasting is not completely fixed, so that alarm evasion cannot be performed in a mode of presetting a program running diagram, and further, when the situation occurs in the programs, a large amount of invalid alarms are often generated, and great troubles are caused to operators on duty.
Based on this, the embodiment of the present application provides a method for detecting a playing state of a program, which is helpful for improving the accuracy of a state detection result of a program to which a program detection picture belongs.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for detecting a program playing status according to an embodiment of the present application. As shown in fig. 1, a method for detecting a program playing status provided in an embodiment of the present application includes:
s101, acquiring a program detection picture from video stream data;
s102, determining a comparison hash value of the program detection picture based on material configuration information in preset configuration information of a channel to which the program detection picture belongs;
s103, comparing the comparison hash value of the program detection picture with a prestored hash value of a prestored material picture of a channel to which the program detection picture belongs to determine a comparison result of the program detection picture;
s104, determining a warning result of the program detection picture based on warning configuration information in the preset configuration information;
and S105, determining the state detection result of the program to which the program detection picture belongs based on the comparison result and the warning result.
As shown in fig. 2, fig. 2 is a schematic structural diagram of a storage material library of channel preset configuration information according to an embodiment of the present application. As shown in fig. 2, the material library includes preset configuration information of each channel (channel 1, …, channel n) and pre-stored material pictures. The preset configuration information includes channel attribute information, material configuration information, warning configuration information and the like of a channel to which the program detection picture belongs, wherein the channel attribute information can include a management standard channel table, a management channel group, a channel name, a channel belonging mechanism, a channel playing time table and the like; the material configuration information may include an image detection area, an image exclusion area, and the like; the alert configuration information may include alarm condition information for the channel, indicator threshold information for the channel, and the like. The pre-stored material picture refers to a preset off-air picture of the channel, namely a picture played in a preset off-air time period of the channel.
In step S101, a program detection picture of a program being played at the current time is acquired from video stream data at preset time intervals.
Further, in step S102, a comparison hash value of the program detection picture may be calculated by using an image perception algorithm (PHASH) according to the material configuration information in the acquired preset configuration information, so as to compare the comparison hash value with a pre-stored material picture in a subsequent process.
In order to relax the limitation on the resolution of the image, that is, the image resolution of the program detection picture is not mandatory to be consistent with the image resolution of the pre-stored material picture, in the present application, the program detection picture is processed based on the material configuration information, specifically, step S102 includes: determining a target detection area from the program detection picture based on material configuration information in preset configuration information of a channel to which the program detection picture belongs; filling areas except the target detection area in the program detection picture into black to obtain a target detection picture; and calculating the target detection picture by utilizing a hash algorithm to obtain a comparison hash value of the program detection picture.
For a program detection picture, firstly, a target detection area which can be compared in the program detection picture is determined according to material configuration information, and characteristic information which can represent the broadcasting state of a program to which the program detection picture belongs is displayed in the target detection area which can be compared under normal conditions; therefore, in order to reduce the data processing amount during image processing, the areas of the program detection screen other than the target detection area are filled with black, and the filled program detection screen is determined as the target detection screen; further, calculating a target detection picture by using a hash algorithm to obtain a comparison hash value of the program detection picture; here, as an example, the target detection picture may be calculated by using an image sensing algorithm, it should be noted that the image sensing algorithm is only one method for calculating the comparison hash value of the program detection picture, and other hash algorithms may also be used for calculating the comparison hash value of the program detection picture, which is not limited herein.
In step S103, the comparison hash value of the program detection picture is compared with the pre-stored hash value of the pre-stored material picture of the channel to which the program detection picture belongs, so as to determine the comparison result of the program detection picture, that is, determine whether the program detection picture is consistent with the pre-stored material picture.
Here, the comparison hash value of the program detection picture obtained by calculation may be a 64-bit numerical value, and the comparison hash value of the program detection picture is compared with the prestored hash value of the prestored material picture, specifically, the number of the same number of bits in the comparison hash value and the prestored hash value is determined; the more the number of the same digits is, the more similar the program detection picture and the pre-stored material picture is, and when the number of the same digits reaches a preset number threshold value, the program detection picture is determined to be consistent with the pre-stored material picture; otherwise, determining that the two are inconsistent. When the program detection picture is consistent with the pre-stored material picture, determining that the program detection picture is in a non-playing state; otherwise, determining that the program detection picture is in a non-stop state.
The method comprises the steps that at least one pre-stored material picture is pre-stored in a channel to which a program detection picture belongs, when more than two pre-stored material pictures are pre-stored, a comparison hash value of the program detection picture is compared with a pre-stored hash value of each pre-stored material picture, and a comparison result of the program detection picture is determined; for example, when three pre-stored material pictures exist, the comparison hash value of the program detection picture is respectively compared with the pre-stored hash value of the first pre-stored material picture, the pre-stored hash value of the second pre-stored material picture and the pre-stored hash value of the third pre-stored material picture; when the program detection picture is consistent with two pre-stored material pictures in the three pre-stored material pictures, the program detection picture can be confirmed to be in a non-stop state.
Specifically, the pre-stored hash value of each pre-stored material picture is calculated through the following steps:
step 1: determining a material detection area which can be compared in the prestored material picture according to the material configuration information, wherein characteristic information which can represent the broadcasting state of the program to which the prestored material picture belongs is displayed in the material detection area which can be used for comparison under the common condition;
step 2: in order to reduce the data processing amount in the image processing process, filling the areas except the material detection area in the pre-stored material picture into black to obtain the filled pre-stored material picture;
and step 3: calculating the filled prestored material picture by utilizing a Hash algorithm to obtain a comparison Hash value of the prestored material picture; here, as an example, the filled pre-stored material picture may be calculated by using an image sensing algorithm, it should be noted that the image sensing algorithm is only a method for calculating a comparison hash value of the filled pre-stored material picture, and other hash algorithms may also be used for calculating the comparison hash value of the filled pre-stored material picture, which is not limited herein.
In step S104, the program detection picture is detected according to the warning configuration information in the preset configuration information, and whether the program to which the program detection picture belongs at the current time has warning information that satisfies the off-air warning condition is determined according to the picture data and the index data of the program detection picture, so as to obtain a warning result of the program detection picture.
Here, the off-air alert condition includes one or more of:
a. the program is interrupted and lasts for a specified threshold time;
b. video loss, lasting for a specified threshold time;
c. video decoding is abnormal and lasts for a specified threshold time;
d. an audio decoding anomaly persists for a specified threshold of time;
e. the program bandwidth is below the threshold rate and lasts for a specified threshold time.
Further, when the off-air warning condition of the program detection picture is determined, the warning result of the program detection picture is determined; specifically, when the program detection picture meets any one of the stop-off warning conditions, it is determined that warning information meeting the stop-off warning condition exists in the program detection picture.
In step S105, the playing status of the program to which the program detection screen belongs may be determined based on the obtained comparison result and the warning result, so as to more accurately determine the status detection result of the program to which the program detection screen belongs.
Here, the state detection result may include: any one of normal playing, suspected stop playing and stop playing confirmation.
In one possible implementation, step S105 includes: when the comparison result indicates that the program to which the program detection picture belongs is in a non-stop state and the warning result indicates that no warning information exists in the program detection picture, determining that the program to which the program detection picture belongs is in a normal playing state; and when the comparison result indicates that the program to which the program detection picture belongs is in a non-playing state and the warning result indicates that warning information exists in the program detection picture, performing secondary judgment on the playing state of the program to which the program detection picture belongs, and determining a state detection result of the program to which the program detection picture belongs.
Here, when determining the state detection result of the program according to the program detection screen, the state detection result needs to be determined doubly by the comparison result and the warning result; specifically, when the comparison result indicates that the program to which the program detection picture belongs is in the non-stop state and the warning result indicates that the warning information meeting the stop warning condition does not exist in the program detection picture, it is determined that the state detection result of the program to which the program detection picture belongs is normally played.
And when the comparison result indicates that the program to which the program detection picture belongs is in the off-air state and/or the warning result indicates that warning information meeting the off-air warning condition exists in the program detection picture, performing secondary judgment on the playing state of the program to which the program detection picture belongs, and further more accurately determining the state detection result of the program to which the program detection picture belongs.
In a possible implementation manner, the secondarily determining the playing status of the program to which the program detection picture belongs and determining the status detection result of the program to which the program detection picture belongs includes: judging whether the acquisition time of the program detection picture is enabled at a fixed time interval; if yes, determining that the state detection result of the program detection picture is suspected to stop broadcasting; if not, determining whether the acquisition time is in a fixed off-air time period; if yes, determining that the state detection result of the program detection picture is suspected to stop broadcasting; if not, determining that the state detection result of the program to which the program detection picture belongs is determined to stop playing.
The fixed time period enables the preset time period, the fixed time period enables the representation of the preset time required for detecting the playing state of the channel according to the playing condition of the channel, and because the playing conditions of the programs of all the channels are different, the program playing states of all the channels can not be detected in a unified detection mode at the same time, so that the program playing state of each channel can be detected in a targeted manner by setting the fixed time period enables.
Judging whether the acquisition time of the program detection picture is enabled at a fixed time interval; if yes, determining that the state detection result of the program detection picture is suspected to stop broadcasting; and if not, further judging whether the acquisition time is in a fixed off-air time period.
The fixed off-air time period represents a program off-air time period preset by the channel, and the channel is in the equipment maintenance time in the time period, at the moment, no program is played, and a preset off-air picture is used for replacing the program off-air time period. Because the overhaul time of each channel is inconsistent, in order to accurately determine the program playing state of each channel, whether the acquisition time of the program detection picture is in the fixed off-air time period is further determined when the state detection result of the program is determined, and if the acquisition time of the program detection picture is in the fixed off-air time period, the state detection result of the program to which the program detection picture belongs is determined to be suspected off-air; if not, determining that the state detection result of the program to which the program detection picture belongs is determined to stop playing.
When the comparison result indicates that the program to which the program detection picture belongs is in the non-playing state, but the warning result indicates that no warning information exists in the program detection picture, the state detection result of the program to which the program detection picture belongs can be determined according to the comparison result, the state detection result of the program to which the program detection picture belongs is determined according to the warning result, and if the determined state detection results are inconsistent, the two state detection results are reported together.
When the comparison result indicates that the program to which the program detection picture belongs is in the non-off-air state, but the warning result indicates that warning information exists in the program detection picture, the state detection result of the program to which the program detection picture belongs can be determined according to the comparison result, the state detection result of the program to which the program detection picture belongs is determined according to the warning result, and if the determined state detection results are inconsistent, the two state detection results are reported together.
As shown in fig. 3, fig. 3 is a schematic view of a detection flow of a state detection result according to an embodiment of the present application. As shown in fig. 3, step 301: acquiring a program detection picture, and respectively executing the step 302 and the step 303; step 302: determining a comparison result of the program detection picture, and executing step 304; step 303: determining the warning result of the program detection picture, and executing step 305; step 304: judging whether the program of the program detection picture is in a stop-broadcasting state according to the comparison result, if not, executing step 306; if yes, go to step 307; step 305: determining whether the detection picture of the program has alarm information meeting the stop-off alarm condition according to the alarm result, if yes, executing step 307; if not, go to step 311; step 306: determining that the state detection result of the program to which the program detection picture belongs is normal playing; step 307: judging whether the acquisition time of the program detection picture is enabled at a fixed time interval or not, if not, executing a step 308; if yes, go to step 309; step 308: judging whether the acquisition time of the program detection picture is in a fixed off-air time period, if so, executing step 309; if not, go to step 310; step 309: determining that the state detection result of the program to which the program detection picture belongs is suspected to stop broadcasting; step 310: determining that the state detection result of the program to which the program detection picture belongs is determined to stop playing; step 311: and determining that the state detection result of the program to which the program detection picture belongs is normal playing.
In a possible implementation manner, after step S105, the detection method further includes: and reporting the state detection result so that a monitoring person can adjust the playing content of the channel to which the program detection picture belongs based on the state detection result.
Here, when reporting the status detection result, it may be determined whether the status detection result of this time changes from the last status detection result of the channel to which the program detection screen belongs, and if so, the status detection result of this time is reported, so that the monitoring person adjusts the playing content of the channel to which the program detection screen belongs based on the status detection result of this time.
If the current state detection result is consistent with the last state detection result of the channel to which the program detection picture belongs, the current state detection result is not reported so as to avoid increasing unnecessary workload of monitoring personnel by repeated reporting.
In a possible implementation manner, in order to further increase the detection rate of the program detection picture, the received program detection picture is allocated to the comparison processing thread with the least processing tasks, and after the program detection picture is acquired from the video stream data, the detection method further includes: acquiring the task processing quantity of each comparison processing thread; and distributing the program detection picture to the comparison processing thread with the least task processing quantity so as to calculate the comparison hash value of the program detection picture. And then, the tasks to be processed are more reasonably distributed for each comparison processing thread, and the utilization rate of the comparison processing threads is greatly improved.
