Referring to fig. 2, a first embodiment of a method for controlling a television according to the present invention includes:
step S10, when detecting the channel switching, obtaining a playing parameter corresponding to the currently playing channel, where the playing parameter includes at least one of an image display parameter and a sound parameter.
And step S20, playing the audio and video data of the channel according to the playing parameters.
When the television plays the audio and video data, the television acquires the playing parameter information set by the current television, and then plays the audio and video data according to the playing parameters. Generally, the playing parameters of a television mainly include image display parameters and sound parameters, for example, the common image display parameters include brightness, chromaticity, color temperature, contrast, chromaticity, and sharpness; common sound parameters are volume and pitch. Because most of television users are not proficient in setting the playing parameters of the television for different video types, the video playing effect is more appropriate to the video content, and the watching value of the video is improved. Therefore, a training model is obtained through learning and training, corresponding playing parameters are set for each channel of the television according to the training model, when the fact that a user switches a television channel is detected, the playing parameters corresponding to the switched channel are obtained, the playing parameters are used for playing audio and video data of the channel, and the video playing effect is improved.
The training model according to which the playing parameters corresponding to each video are based can be that after the video information of each video is acquired by a server corresponding to the television and is trained, the video information is synchronized in the television; or the television set can be trained according to the video information of each video.
In addition, because the values of the playing parameters corresponding to the same playing type in the televisions with different models are different, the method for acquiring the playing parameters corresponding to each video can also bind each channel to the corresponding playing type according to the training model, and can determine the playing parameters corresponding to each channel in the television according to the software and hardware information and the playing type such as the model of the television, so that the playing parameters of the channel are suitable for the audio and video playing of the channel in the current television. The playing type is a playing type which is already possessed by the television when leaving a factory, the playing type is divided into an image type and a sound type, and the commonly used playing types are as follows: standard, theater, movie, nature, and text, etc.
Further, the playing type corresponding to each channel can be determined by acquiring the video information in each channel, acquiring the dimension information of the channel according to the video information, and determining the playing type corresponding to the channel according to the dimension information. The dimension information includes what video types the channel has and the playing time length percentage of each video type, the playing time length percentage refers to the percentage of the playing time length of the video content playing of the video type in the total training video acquisition time length, and the sum of the playing time length percentages of the video types in the same channel is 100%.
The following five channels are exemplified:
each channel is divided into 5 dimensions, i.e. 5 video types: news, drama/movie, sports/gaming, animation/kids, and art/fun/shopping. The numerical values in the table represent the respective dimension values, i.e. the play-out time-length percentages for the respective video types. According to the dimension information in the table above, the playing type corresponding to each channel can be determined:
television shopping: image type is standard, sound type is human voice
CCTV 2: type of image as text and type of voice as voice
CCTV 5: type of picture theater, type of sound theater
CCTV 6: picture type, sound type, and movie
Golden eagle cartoon: image type as natural, sound type as game
When the television acquires the playing type information, determining playing parameters corresponding to each channel according to the model information of the television and the playing type information, and playing audio and video data of the corresponding channel by adopting the playing parameters; or when the information acquired by the television is the dimension information of each channel, the television automatically acquires the playing type corresponding to each channel according to the dimension information, further determines the playing parameter corresponding to each channel according to the model information of the television and the playing type information, and plays the audio and video data of the corresponding channel by adopting the playing parameter.
In this embodiment, when the television detects channel switching, the television obtains a playing parameter corresponding to a switched channel according to a pre-trained training model, and uses the playing parameter to play audio and video data of the channel, and sets the playing parameter of the television according to a video type played by each channel in a targeted manner, so that a video playing effect is more appropriate to video content, and the video playing effect is improved.
Referring to fig. 3, a second embodiment of the method for controlling a television according to the present invention, based on the first embodiment, before the step S10, further includes:
step S30, when receiving the power-on command, sends a request for synchronizing the dimension information to the server.
And step S40, receiving the dimension information fed back by the server according to the dimension information synchronization request.
Since the program schedule in a tv channel is not constant, the type of video played on the channel and the playing time duration corresponding to the video type will also change in response to the change of the program. Therefore, after the channel dimension information is trained, the server of the television collects the video information of the channel in real time or at regular time, and updates the channel dimension information according to the channel video information. When the television is started, the television is controlled to send a synchronization request of the dimension information to the server, the server feeds back the current latest dimension information to the television according to the received dimension information synchronization request, so that the television can update the playing parameters of the channels according to the latest dimension information, the updated playing parameters are adopted to play the audio and video data of the channels, the current film watching requirement of a user can be met, and the image and sound playing effect of the video is guaranteed all the time.
In this embodiment, when the television is turned on, a dimension information synchronization instruction is sent to the server of the television, the latest dimension information fed back by the server according to the dimension synchronization instruction is obtained, the playing parameters of the channel are updated according to the latest dimension information, and the audio and video data of the channel are played by using the updated playing parameters, so that the current viewing requirement of a user can be met, and the image and sound playing effect of the video can be guaranteed at any time.
Referring to fig. 4, a third embodiment of the method for controlling a television according to the present invention, based on the first or second embodiment, further includes, after step S20:
step S50, when receiving the dimension information updating instruction, sending a dimension information updating request to the server;
step S60, receiving the dimension information fed back by the dimension information updating request, and determining the playing parameter corresponding to the channel according to the dimension information.
And returning to the step S20, namely playing the audio and video data of the channel according to the playing parameters.
The dimension information of each channel of the television can be marked with the identity by a method of marking the version number, and the old and new degree of the current dimension information can be known by checking the version number of the dimension information. When the dimension information of the television is not updated for too long, namely the version number is too old, the user can be prompted to update the dimension information. After the television is networked, the server where the television is located can obtain the version number of the dimension information of the television, and when the server identifies that the dimension information of the television is too old, the server sends prompt information for updating the dimension information to the television.
And when the television receives an update instruction of the dimension information, sending a dimension information update request to the server to request the latest dimension information in the synchronous server. And after receiving the latest dimension information fed back by the server according to the dimension information request, the television acquires the playing parameter of the current channel according to the latest dimension information, controls the television to return to the step 20, and plays the audio and video data of the channel by using the newly acquired playing parameter.
In this embodiment, when the television receives an update instruction of the dimension information, a dimension information update request is sent to the server to request for synchronizing the latest dimension information in the server. And after receiving the latest dimension information fed back by the server according to the dimension information request, the television acquires the playing parameter of the current channel according to the latest dimension information, and the audio and video data of the channel is played by adopting the newly acquired playing parameter. In the playing process of the television, the dimension information of the television is updated so as to avoid the influence on the film watching effect caused by the fact that the current dimension information of the television is not accordant with the current video playing.
Referring to fig. 5, a fourth embodiment of the method for controlling a television according to the present invention is based on any of the first to third embodiments, and after step S20, the method further includes:
step S70, when receiving the dimension information updating instruction, determining whether the television is connected to the network.
Step S80, when the television is not connected to the network, obtaining video information of the currently played video of the channel.
And step S90, updating the dimension information of the channel according to the video information.
And S100, acquiring the playing parameters of the channel according to the updated dimension information.
And returning to the step of executing the step S20, namely, playing the audio and video data of the channel according to the playing parameter.
Step S50, when the television is connected to the network, the dimension information update instruction is forwarded to the server.
When the television receives the dimension information updating instruction, a dimension information updating request is usually sent to a server corresponding to the television to obtain the latest dimension information fed back by the server, and the latest dimension information is used as the dimension information of the current television, so that the dimension information is updated. However, when the television is not connected to the network, the dimension information cannot be synchronized with the server. At the moment, the television automatically collects the video information of the currently played video, and the dimension information is updated according to the video information. When the television receives the dimension information updating instruction, the television is already connected with the network, and the television sends the dimension information updating instruction to the server to receive the latest dimension information fed back by the server according to the dimension information updating request, as in the previous embodiment. And after the dimension information of the television is updated, acquiring the playing parameter of the current channel according to the updated dimension information, and playing the audio and video data of the channel by adopting the newly acquired playing parameter.
In this embodiment, when the television receives the dimension information updating instruction, it is determined whether the television is connected to a network, and when the television is not connected to the network, the television automatically acquires video information of a currently played video, and updates the dimension information according to the video information; when the television is connected with the network, the television sends a dimension information updating instruction to the server so as to receive the latest dimension information fed back by the server according to the dimension information updating request and update the current dimension information of the television. By additionally judging whether the television is connected with the network or not, the problem that the dimension information of the television cannot be updated when the television is not connected with the network is avoided, the television is ensured to be capable of acquiring the latest playing parameter of the current channel, and the audio and video data of the current channel is played by adopting the latest playing parameter of the current channel.
Referring to fig. 6, a fifth embodiment of the method for controlling a television according to the present invention is based on any of the first to fourth embodiments, and after step S20, the method further includes:
step S110, when a dimension information updating instruction is received, video information of the channel is obtained;
step S120, identifying image information and sound information in the video information, dividing the channel into a plurality of video types according to the image information and the sound information, and acquiring the playing time length of each video type;
step S130, updating the dimension information of the channel according to the video type and the playing duration of the video type.
When the dimension information is updated, collecting videos played by the channel for a period of time, dividing the videos into a plurality of video types according to a training model trained in advance by comparing image information and sound information of the videos, obtaining the playing time of each video type, and taking the percentage of the playing time in the total collection time as the percentage of the playing time of the video type. And obtaining the dimension information of the channel according to each video type and the playing time length percentage corresponding to each video type. The same method can obtain the dimension information of each channel in the television. And replacing the existing dimension information of the television with the newly acquired dimension information, thereby achieving the purpose of updating the dimension information. The dimension information can be updated by a television or a server of the television.
In addition, when the playing duration of the acquired video type is less than the preset duration, the frequency of the video type in the channel is low, and errors may also occur in the classification of the video type, so that only the video type with the playing duration greater than the preset duration is selected as effective data, the dimension information is calculated according to the effective data, the dimension information of the television is updated according to the calculated dimension information, and the problem that the dimension information is not updated properly due to information processing errors is solved.
In addition, when the difference value between the playing time length percentage of the video type in the newly acquired dimension information and the playing time length percentage of the video type in the original dimension information is greater than a preset threshold value, it can be shown that the video played by the channel has a large change. However, there is usually no more prominent transition due to the type of video being played on a fixed channel. Therefore, when the difference value between the playing time length percentage of the video type in the newly acquired dimension information and the playing time length percentage of the video type in the original dimension information is larger than the preset threshold value, it can be judged that data acquisition or calculation has errors, and the updating of the dimension information at this time is cancelled. For example, in the golden eagle cartoon channel, the playing time length percentage of the animation/juvenile type in the original dimension information is 70%, and the playing time length percentage of the animation/juvenile type in the updated dimension information is 40%, according to the distribution rule of the video types in the conventional television channel, the video of the animation/juvenile type in the golden eagle cartoon channel does not change so much, so that the updating is cancelled, and the original dimension information is recovered. Further, prompt information of error updating of the dimension information can be fed back, so that a user can trigger the dimension updating instruction again to update the dimension information again.
In this embodiment, when receiving dimension information update, acquiring video information of the channel for a period of time, dividing a video in the channel into a plurality of video types according to a training model trained in advance by comparing image information and sound information in the video information, acquiring a play time of each video type, and taking a percentage of the play time in the total acquisition time as a play time percentage of the video type. And the dimension information of the channel is composed of each video type and the playing time length percentage corresponding to each video type. And replacing the acquired dimension information with the existing dimension information of the television, thereby updating the dimension information. The dimension information is determined through the classification of the videos and the playing duration of each classification, so that the updated dimension information can better meet the current video playing requirement of the channel, and the playing effect of the television is improved.
In addition, an embodiment of the present invention further provides a television, where the television includes: the control program of the television set is stored on the memory and can run on the processor, and when being executed by the processor, the control program of the television set realizes the steps of the control method of the television set according to the above embodiments.
