According to research, in order to ensure normal broadcasting of television programs, a broadcasting mechanism generally monitors broadcasting pictures of videos in the broadcasting process of the videos, and monitors and alarms when broadcasting states of the television programs are in abnormal broadcasting states such as black screens, static pictures, no accompanying sound and the like. Because of the requirements of equipment overhaul, updating and the like, part of television programs stop broadcasting formal programs in a specific period, and the situation that a broadcasting stopping picture and background music are replaced exists, however, the broadcasting stopping picture of part of programs has an active area such as a traveling clock, a small window video and the like, and the broadcasting stopping time is not completely fixed, so that an alarm can not be avoided by presetting a program running chart, and further, when the programs are in the situation, a large number of invalid alarms are often generated, and great trouble is caused to operators on duty.
Based on this, the embodiment of the application provides a method for detecting the playing state of a program, which is helpful to improve the accuracy of the state detection result of the program to which the program detection picture belongs.
Referring to fig. 1, fig. 1 is a flowchart of a method for detecting a playing state of a program according to an embodiment of the present application. As shown in fig. 1, the method for detecting a playing state of a program provided in the 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 the pre-stored hash value of the pre-stored material picture of the channel to which the program detection picture belongs, and determining 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;
s105, determining a state detection result of the program to which the program detection picture belongs based on the comparison result and the warning result.
Fig. 2 is a schematic diagram of a structure 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 comprises 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 comprise a management standard channel table, a management channel group, a channel name, a mechanism to which the channel belongs, 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 alert condition information for the channel, indicator threshold information for the channel, and the like. The pre-stored material pictures refer to preset off-air pictures of the channel, namely pictures played in a preset off-air time period of the channel.
In step S101, a program detection picture of a program played at a current time is obtained from video stream data at a preset time interval.
Further, in step S102, a comparison hash value of the program detection picture may be calculated by using an image sensing algorithm (PHASH) according to the material configuration information in the obtained preset configuration information, so as to compare with the pre-stored material picture in a subsequent process.
In order to relax the limitation on the resolution of the image, that is, not to force the image resolution of the program detection picture to be consistent with the image resolution of the pre-stored material picture, the program detection picture is processed based on the material configuration information in the present application, 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 the areas except the target detection areas in the program detection picture with black to obtain a target detection picture; and calculating the target detection picture by using a hash algorithm to obtain a comparison hash value of the program detection picture.
For the program detection picture, firstly, determining a target detection area which can be compared in the program detection picture according to the material configuration information, wherein characteristic information which can represent the broadcasting state of the 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 in the image processing process, the areas except the target detection areas in the program detection picture are filled with black, and the filled program detection picture is determined as the target detection picture; 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, and it should be noted that the image sensing algorithm is only a method for calculating the comparison hash value of the program detection picture, and other hash algorithms may be used to calculate the comparison hash value of the program detection picture, which is not particularly 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.
The comparison hash value of the program detection picture obtained by calculation can be a 64-bit value, and the comparison hash value of the program detection picture is compared with the pre-stored hash value of the pre-stored material picture, specifically, the number of the same digits in the comparison hash value and the pre-stored 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 are, and when the number of the same digits reaches a preset number threshold, the program detection picture is determined to be consistent with the pre-stored material picture; otherwise, it is determined 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-off-air state.
At least one pre-stored material picture is pre-stored in the channel to which the program detection picture belongs, and when more than two pre-stored material pictures are pre-stored, the comparison hash value of the program detection picture is respectively compared with the pre-stored hash value of each pre-stored material picture, so that the comparison result of the program detection picture is determined; for example, when three pre-stored material pictures exist, comparing hash values of the program detection pictures with the pre-stored hash values of the first pre-stored material picture, the pre-stored hash values of the second pre-stored material picture and the pre-stored hash values of the third pre-stored material picture respectively; 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 obtained through the following steps:
step 1: determining a material detection area which can be compared in the pre-stored material pictures according to the material configuration information, wherein the characteristic information which can represent the broadcasting state of the program of the pre-stored material pictures is displayed in the material detection area which can be used for comparison under the normal condition;
step 2: in order to reduce the data processing amount in the image processing process, filling the areas except the material detection areas in the pre-stored material pictures into black to obtain filled pre-stored material pictures;
step 3: calculating the filled pre-stored material pictures by using a hash algorithm to obtain comparison hash values of the pre-stored material pictures; here, as an example, the filled pre-stored material picture may be calculated by using an image sensing algorithm, and 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 be used to calculate 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 alert configuration information in the preset configuration information, and whether the alert information satisfying the off-air alert condition exists in the program to which the program detection picture belongs at the current moment is judged according to the picture data and the index data of the program detection picture, so as to obtain the alert result of the program detection picture.
Here, the off-air warning condition includes one or more of the following:
a. program interruption, lasting for a specified threshold time;
b. video is lost for a specified threshold time;
c. video decoding is abnormal, and the time of a specified threshold is continued;
d. the audio decoding is abnormal, and the time of a specified threshold is continued;
e. the program bandwidth is below the threshold rate and continues for a specified threshold time.
Further, when the program detection picture is determined, the off-air warning condition is determined, and when a warning result of the program detection picture is determined; specifically, when the program detection picture meets any one of the above-mentioned off-air warning conditions, it is determined that warning information meeting the off-air warning conditions exists in the program detection picture.
In step S105, the play status of the program belonging to the program detection picture may be doubly determined based on the obtained comparison result and the warning result, so as to more accurately determine the status detection result of the program belonging to the program detection picture.
Here, the state detection result may include: any one of normal play, suspected off-air, and confirm off-air.
In one possible implementation, step S105 includes: when the comparison result indicates that the program of the program detection picture 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 of the program detection picture is in a normal play state; when the comparison result indicates that the program of the program detection picture is in a non-playing state and the warning result indicates that warning information exists in the program detection picture, the playing state of the program detection picture is secondarily judged, and the state detection result of the program detection picture is determined.
Here, when determining the state detection result of the program according to the program detection picture, the state detection result needs to be doubly determined through 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 a non-stop state, and the warning result indicates that warning information meeting the stop warning condition does not exist in the program detection picture, the state detection result of the program to which the program detection picture belongs is determined to be normally played.
When the comparison result indicates that the program of the program detection picture is in the off-air state and/or the warning result indicates that the warning information meeting the off-air warning condition exists in the program detection picture, the playing state of the program detection picture is secondarily judged, and then the state detection result of the program detection picture is more accurately determined.
In one possible implementation manner, the determining the state 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 in a fixed period; if yes, determining that the state detection result of the program to which the program detection picture belongs is suspected off-air; if not, determining whether the acquisition time is in a fixed off-air period; if yes, determining that the state detection result of the program to which the program detection picture belongs is suspected off-air; if not, determining that the state detection result of the program to which the program detection picture belongs is confirmation of stopping the broadcasting.
The fixed time period enabling is preset, the fixed time period enabling characterizes the time 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 unified detection mode cannot be adopted, and the program playing states of all the channels can be detected at the same time.
Judging whether the acquisition time of the program detection picture is enabled in a fixed period; if yes, determining that the state detection result of the program to which the program detection picture belongs is suspected off-air; if not, further judging whether the acquisition time is in a fixed off-air period.
The fixed off-stream period characterizes a preset program off-stream period of the channel, and the channel is in equipment maintenance time in the period, at the moment, no program is played, and a preset off-stream picture is used for replacing the program off-stream 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 a fixed off-stream 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-stream period, the state detection result of the program to which the program detection picture belongs is determined to be suspected off-stream; if not, determining that the state detection result of the program to which the program detection picture belongs is confirmation of stopping the broadcasting.
When the comparison result indicates that the program of the program detection picture is in a 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 detection picture can be determined according to the comparison result, then the state detection result of the program detection picture is determined according to the warning result, and if the determined state detection results are inconsistent, both the state detection results are reported.
When the comparison result indicates that the program of the program detection picture is in a non-stop state, but the warning result indicates that warning information exists in the program detection picture, the state detection result of the program detection picture can be determined according to the comparison result, then the state detection result of the program detection picture 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 diagram of a state detection result detection flow provided in an embodiment of the present application. As shown in fig. 3, step 301: acquiring a program detection picture, and executing step 302 and step 303 respectively; step 302: determining a comparison result of the program detection picture, and executing step 304; step 303: determining a warning result of the program detection picture, and executing step 305; step 304: judging whether the program to which the program detection picture belongs is in a broadcasting cut-off state according to the comparison result, and if not, executing a step 306; if yes, go to step 307; step 305: determining whether the program detection picture has alarm information meeting the off-air alarm condition according to the alarm result, if so, 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 play; step 307: judging whether the acquisition time of the program detection picture is enabled in a fixed period, if not, executing 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 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 off-air; step 310: determining that the state detection result of the program to which the program detection picture belongs is confirmation of stopping broadcasting; step 311: and determining the state detection result of the program to which the program detection picture belongs as normal play.
In one 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 the status detection result is reported, it may be determined whether the status detection result is changed from the last status detection result of the channel to which the program detection picture belongs, if yes, the status detection result is reported, so that the monitoring personnel adjusts the playing content of the channel to which the program detection picture belongs based on the status detection result.
If the state detection result is consistent with the last state detection result of the channel to which the program detection picture belongs, the state detection result can not be reported, so that the unnecessary workload of monitoring personnel is not increased by repeated reporting.
