step S10, when the current TV starts application, the original playing data stream of the TV is obtained;
based on the current television application, the television application refers to a television playing operation, and the played content includes, but is not limited to, audio and video files, pictures and the like. Therefore, when the application of the current television is confirmed to be started, the original playing data stream of the television is obtained, the original playing data stream is defined as the data stream formed by the transmission of the original playing file for playing transmitted by the data network, and whether the playing picture of the current television is in a static state or not is confirmed according to the currently obtained original playing data stream.
Further, the step of currently acquiring the original broadcast data stream is to determine whether a current television broadcast picture is still, further adjust television parameters to avoid the occurrence of picture ghost to cause a screen burn condition, and based on the avoidance of the screen burn condition, the step of detecting the television picture can be performed through a preset screen burn prevention mechanism of the television, that is, when the current television starts an application, the step of acquiring the original broadcast data stream of the television includes:
starting a preset screen burning prevention mechanism according to the application of the current television, and initializing the functional parameters of the screen burning prevention mechanism;
and acquiring an initialization function parameter, and acquiring an original playing data stream of the television according to the initialization function parameter.
When the current television application is detected, starting a preset television burn-in prevention mechanism, wherein the operation of starting the television burn-in prevention mechanism comprises initializing functional parameters of the television burn-in prevention mechanism, the functional parameters are defined as detection data for detecting the still television picture, and comprise related function setting parameters such as detection time, detection period and the like, and the function setting parameters can be set and realized in related system function setting during application. Therefore, the initialization function parameter is obtained according to the function parameter of the current initialized screen burning prevention mechanism, and the original playing data stream of the current television playing picture is obtained based on the data content of the initialization function parameter.
In addition, when different televisions are used, the sources of original playing data streams of the different televisions are different, and the different data stream sources do not necessarily support the operation of obtaining the original playing data streams, and based on the situation, whether the current television playing picture is a still picture can be determined by obtaining the picture screenshot of the current television playing picture, that is, the method for preventing the afterimage of the still picture based on the playing data streams further comprises the following steps:
when the original playing data stream cannot be acquired, acquiring a picture screenshot of a current television picture;
and confirming whether the television playing picture is a still picture according to the picture screenshot of the television picture.
According to the current television application, when the data source of the current playing picture is determined not to support the acquisition of the original playing data stream, namely the original playing data stream cannot be acquired, the picture screenshot of the current television picture is acquired, the picture screenshot of the television picture can be stored in a display picture of the current television through a universal screenshot interface of a current television system to form a picture screenshot, and whether the television playing picture is a static picture or not is determined according to the currently acquired picture screenshot.
Step S20, determining whether the playing picture of the television is still according to the obtained original playing data stream;
according to the obtained original playing data stream based on the playing picture of the current television, whether the playing picture of the current television is static or not is confirmed through the data content of the original playing data stream, namely whether the playing picture of the current television is a static picture or not is confirmed. Further, when determining whether the television playing picture is static by confirming the data content of the original playing data stream, the data content of the original playing data stream is defined as the data frame information in the original playing data stream, so that the frame information is extracted from the original playing data stream, and if the extracted frame information is consistent, the playing picture of the current television is confirmed to be static; and if the extracted frame information is inconsistent, determining that the current television playing picture is not in a static state.
As described above, the step of determining whether the playing picture of the current television is still according to the frame information of the acquired original playing data stream, when it is determined that the playing picture of the current television is in a still state, adjusting the playing parameters of the current television based on the current preset anti-afterimage control operation, and when it is determined that the playing picture of the current television is not a still picture, that is, when it is determined that the playing picture of the television is still according to the acquired original playing data stream includes:
extracting frame information of the original playing data stream, and comparing the extracted information content of the frame information;
and confirming whether the playing picture of the television is static or not according to the comparison result.
And extracting frame information from the obtained original playing data stream, and confirming whether the frame information is consistent or not based on the extracted frame information. The operation of confirming whether the extracted frame information is consistent can be confirmed based on the information content of the frame information through comparison, because the frame information is in a picture form, when the information content of the frame information is compared, the operation can be realized through the comparison of the picture content displayed by the frame information, whether the extracted frame information is consistent is confirmed according to a comparison result, and whether a television playing picture based on the frame information is static is further confirmed, and therefore, when the frame information is consistent, the television playing picture is confirmed to be static; and when the frame information is confirmed to be inconsistent, confirming that the playing picture of the television is not static. In addition, because the obtained original broadcast data stream is composed of frame information, and the picture broadcast operation of the television is realized in a mode of rapidly broadcasting the frame information, when the original broadcast data stream is extracted, in order to avoid that the extracted frame information of different pictures makes a comparison result error, an extraction node for extracting the frame information in the current original broadcast data stream, namely the frame information of the original broadcast data stream is extracted, and the step of confirming whether the extracted frame information is consistent comprises the following steps:
confirming an extraction node of the frame information;
and extracting a preset number of frame information from the extraction nodes.
According to the currently acquired original playing data stream, confirming an extraction node for extracting frame information from the original playing data stream, wherein the extraction node is defined as an extraction point in a time range. When the original data stream is played, the playing quality of the original data stream is influenced by the data volume of the frame information in the original playing data stream, so that when the extraction node of the frame information is determined in the obtained original playing data stream, the extraction node of the current frame information can be determined by determining the data parameter of the frame information in the original playing data stream, that is, the extraction node of the frame information is determined by the picture parameter formed by the number of the frame information in the original playing data stream. And the frame information in the extraction node is ensured to be the same picture to the maximum extent, so that the accuracy of confirming the still picture is improved. In this way, according to the confirmed extraction nodes, the frame information is extracted from the extraction nodes, and in addition, in consideration of the running speed of the television system, when the frame information is extracted from the extraction nodes, the extraction operation can be performed by a preset number which is limited, and the preset number can be calculated by counting the total number of the frame information in the extraction nodes.
Further, when extracting frame information from the determined extraction node to determine whether the playing picture of the current television is still, the step of extracting the frame information of the original playing data stream and determining whether the extracted frame information is consistent because the frame information is compared by the picture displayed by the frame information during the comparison of the frame information and the data representation form of the picture is a pixel parameter includes:
respectively calculating and extracting pixel parameters of each frame information;
and confirming whether the extracted frame information is consistent or not according to the calculated pixel parameters.
Confirming the pixel parameters of the frame information according to the extracted frame information of the original playing data stream, and calculating the pixel parameters of the frame information, wherein the pixel parameters of each frame information are respectively calculated because the extracted frame information is in a plurality of numbers, and confirming whether the extracted frame information is consistent according to the calculated pixel parameters, namely when the pixel parameters are compared, confirming whether the frame information is consistent according to the parameter difference value of the pixel parameters of each frame information, namely confirming whether the extracted frame information is consistent according to the calculated pixel parameters comprises the following steps:
calculating parameter difference values among the pixel parameters of each frame information;
and if the parameter difference is smaller than a preset threshold value, confirming that the frame information is consistent.
Calculating parameter difference values among the pixel parameters of the frame information according to the pixel parameters of the frame information counted by the extracted frame information, and confirming that the frame information of which the parameter difference values are calculated is consistent when the calculated parameter difference values are smaller than a preset threshold value according to the calculated parameter difference values.
Step S30, if the displayed image of the tv is still, the screen display brightness of the tv is reduced to prevent image sticking.
And when the fact that the playing picture of the current television is static is confirmed according to the obtained original playing data stream, confirming that the playing picture of the current television possibly has a residual image situation, and reducing the screen display brightness of the current television picture so as to avoid the picture residual image situation of the television picture. When reducing the screen display brightness of the current television picture to prevent picture ghost, the brightness parameter of the screen display brightness of the current television can be correspondingly adjusted, namely if the playing picture of the television is confirmed to be still, the step of reducing the screen display brightness of the television to prevent the picture ghost comprises the following steps:
confirming the brightness parameter of the current television screen display brightness;
and reducing the screen display brightness of the television according to the confirmed brightness parameter.
According to the static condition of the current television picture, confirming the brightness parameter of the display brightness of the current television screen, wherein the brightness parameter is the system playing parameter of the current television playing picture, and reducing the display brightness of the television screen according to the confirmed brightness parameter.
In the embodiment, when the television starts playing audio and video, the screen burning mechanism is started to obtain the original playing data stream, the static condition of the television playing picture is detected through the obtained original playing data, the brightness of the television screen is reduced when the television playing picture is determined to be static, and the phenomenon of picture ghost shadow is avoided through the reduction of the brightness of the television screen, so that the user experience is improved.
