Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a mode switching method of a television. Referring to fig. 1, a flow chart of a mode switching method of a television according to a first embodiment of the present invention is shown.
In this embodiment, the method for switching modes of a television includes:
and step S10, when it is detected that the television enters the home mode operation and a video is played, judging whether the currently played video is played circularly according to the playing time length and the brightness curve of the video.
And step S20, if the video is played circularly, controlling the television to switch to a store mode to operate.
After the television is started, automatically detecting whether the current mode is a market mode, and if the current mode is detected to be the market mode, continuing to operate in the market mode; if the current mode is detected to be the home mode, whether video playing exists is detected, and if the video playing exists, whether the currently played video is played circularly is judged according to the playing duration and the brightness curve of the video.
The method comprises the steps of obtaining the playing time of the video, determining a signal source of the video, obtaining detailed information of the played video based on the signal source of the video when the video starts to be played, and obtaining the playing time of the video from the detailed information. In the process of playing the video, the brightness curve of the video is drawn according to the brightness of the frame picture of the currently played video, and as to whether the video is played circularly or not according to the playing duration and the brightness curve of the video, there may be a variety of embodiments, two of which are listed below for explanation, but the present invention is not limited thereto.
In a first manner, referring to fig. 2, the step of judging whether the currently played video is played circularly according to the playing time length and the brightness curve of the video may include the following detailed steps:
step S21, obtaining the playing time length of the video;
step S22, drawing N brightness curves of the video in continuous N playing time lengths, wherein each brightness curve corresponds to one playing time length;
step S23, taking any one of the N brightness curves as a reference brightness curve, and calculating the similarity between other N-1 brightness curves and the reference brightness curve;
and step S24, judging whether the calculated N-1 similarity degrees are all larger than a preset threshold value, wherein when the N-1 similarity degrees are all larger than the preset threshold value, the video is judged to be played circularly.
In this embodiment, a brightness curve of a video is plotted in units of a playing time period of the video, and the playing time period is described as an example of 10 minutes. And after the video is detected to be played and the signal of the current signal source is stable, the brightness of the video is calculated. In order to ensure the accuracy and effectiveness of the brightness calculation, the playing time length is divided into a plurality of continuous time sections, the divided time sections are used as scales, and the average brightness in the time sections is used as the brightness corresponding to the time sections. N is a positive integer greater than or equal to 3; in another embodiment, the luminance corresponding to the end point or the start point of the time period may be set as the luminance corresponding to the time period, instead of the average luminance.
Hereinafter, the description will be given by taking 5 seconds as an example, and dividing 10 minutes into 120 time periods of 5 seconds. Acquiring all frame pictures of a video within 5 seconds, acquiring the brightness of each frame picture, adding the brightness of all the frame pictures within 5 seconds, dividing the total frame number within 5 seconds to obtain the average brightness value of the video within 5 seconds, acquiring 120 average brightness values of the video within 10 minutes in such a way, and drawing a brightness curve of the video within 10 minutes according to the 120 average brightness values.
In the above manner of plotting the luminance curves, 5 luminance curves were obtained, which were Y1, Y2, Y3, Y4, and Y5, respectively. With Y1 as a reference luminance curve, the similarity between the other luminance curves and the luminance curve is calculated, the similarity between Y2 and Y1 is Δ Y1, the similarity between Y3 and Y1 is Δ Y2, the similarity between Y4 and Y1 is Δ Y3, and the similarity between Y5 and Y1 is Δ Y4. And judging whether the obtained similarities delta Y1, delta Y2, delta Y3 and delta Y4 are all larger than a preset threshold value. Wherein, a threshold value of the similarity, for example, 90%, is preset, and the value is generally an empirical value obtained according to actual scene simulation. And when the N-1 similarity degrees are all judged to be larger than a preset threshold value, judging that the video is played circularly, otherwise, judging that the played video is not played circularly currently.
Further, in order to enhance the accuracy of the judgment, the judgment may be performed a plurality of times. That is, when it is detected that the similarity among the N-1 similarities is smaller than the preset threshold, the related luminance curve is discarded, and the luminance curves within the consecutive N playing time durations are obtained for judgment. For example, when detecting that Δ Y2 is smaller than the preset threshold, Y1, Y2 and Y3 are discarded, and then luminance curves Y6, Y7 and Y8 within 3 continuous playing time lengths after Y5 are acquired. Then, the similarity of the brightness curves is judged according to Y4, Y5, Y6, Y7 and Y8. The number of times of the multiple judgments can be preset according to needs.
If the video played by the television is the circular playing of the same video, if the brightness curve is drawn according to the playing time length of the video, the obtained difference between the continuous brightness curves is very small or even no difference, so that the obtained similarities can reach a preset threshold value, and if the video is not the circular playing of the same video, the difference between the obtained brightness curves is very large and is far lower than the preset threshold value.
In addition, in other embodiments, step S23 may also be: and calculating the similarity of every two adjacent brightness curves in the N brightness curves.
In a second mode, the step of judging whether the currently played video is played circularly according to the playing duration and the brightness curve of the video may include the following refinement steps:
drawing a brightness curve of the video within a preset time interval, wherein the preset time interval is M times of the playing time, and the value of M is a positive integer greater than or equal to 3; and judging whether the acquired brightness curve is a periodically changing curve or not, wherein the changing period of the curve is equal to the playing time, and if so, judging that the video is played circularly.
Judging whether the video is played circularly according to the playing time length and the brightness curve of the video, if so, considering the current working place of the television as a store, therefore, in order to display the video with better display effect and avoid the television from entering standby state without being operated for a long time, controlling the television to be switched to a store mode to operate, and after the television is switched to the store mode, playing according to the preset parameters in the store mode and not entering standby state even if not operated for a long time.
The method for switching modes of the television provided by the embodiment judges whether the currently played video is played circularly or not according to the playing time length and the brightness curve of the video when the television is detected to run in a home mode and the video is played, and controls the television to be switched to a market mode to run if the currently played video is played circularly.
A second embodiment of the mode switching method of a television set according to the present invention is proposed based on the first embodiment. Referring to fig. 3, in this embodiment, before step S10, the method for switching modes of a television further includes:
step S30, when detecting that the television enters the family mode operation and has video playing, acquiring the current mode switching state of the television;
if the acquired mode switching status is automatic switching, step S10 is executed.
In this embodiment, a FLAG is set for the television, and when FLAG is equal to 1, the corresponding mode switching state is automatic switching, and when FLAG is equal to 0, the corresponding mode switching state is manual switching. When the television is shipped, the default FLAG value is 1. When the television is started for the first time, if the fact that the television enters the home mode to operate and video playing exists is detected, the current mode switching state of the television is judged to be automatic switching according to the fact that FLAG is 1, and then the follow-up step of judging whether the video is played circularly is executed.
Further, in order to avoid the phenomenon that when a home user uses a television, the television is automatically switched to a market mode due to the fact that a video is played circularly, the user needs to manually switch the television to the home mode to cause trouble to the user, when the video is judged to be played circularly, prompt information for switching the television to the market mode is output, and when a confirmation instruction triggered based on the prompt information is received, the step of controlling the television to be switched to the market mode to operate is executed; or if no confirmation instruction or cancellation instruction is received within the preset time length for outputting the prompt information, executing the step of controlling the television to switch to the store mode for operation. In addition, if the user uses the home when the played video is detected to be played in a circulating mode, the user can trigger a cancel instruction based on the displayed prompt information, the television can continuously stay in the home mode to operate, normal use of the home user cannot be influenced, and the mode switching state of the television can be changed into manual switching when the cancel instruction is received, namely, the value of the FLAG is changed into 0.
The invention also provides a mode switching device of the television.
Fig. 4 is a functional block diagram of a mode switching device of a television set according to a first embodiment of the present invention.
In this embodiment, the mode switching device of the television set includes:
the loop judgment module 10 is configured to judge whether a currently played video is played in a loop mode according to a playing time length and a brightness curve of the video when it is detected that the television enters a home mode to operate and the video is played;
and the mode switching module 20 is configured to control the television to switch to a store mode for operation if the video is played circularly.
After the television is started, automatically detecting whether the current mode is a market mode, and if the current mode is detected to be the market mode, continuing to operate in the market mode; if the current mode is detected to be the home mode, whether video playing exists is detected, and if the video playing exists, whether the currently played video is played circularly is judged according to the playing duration and the brightness curve of the video.
The method comprises the steps of obtaining the playing time of the video, determining a signal source of the video, obtaining detailed information of the played video based on the signal source of the video when the video starts to be played, and obtaining the playing time of the video from the detailed information. In the process of playing the video, the brightness curve of the video is drawn according to the brightness of the frame picture of the currently played video, and as to whether the video is played circularly or not according to the playing duration and the brightness curve of the video, there may be a variety of embodiments, two of which are listed below for explanation, but the present invention is not limited thereto.
In a first mode, referring to fig. 5, the loop judgment module 10 includes:
a duration obtaining unit 11, configured to obtain a playing duration of the video;
a curve drawing unit 12, configured to draw N brightness curves of the video within N consecutive playing time durations, where each brightness curve corresponds to one playing time duration;
a similarity calculation unit 13, configured to calculate similarities between the other N-1 luminance curves and a reference luminance curve by using any one of the N luminance curves as the reference luminance curve;
and the loop judgment unit 14 is configured to judge whether the calculated N-1 similarities are all greater than a preset threshold, where when the N-1 similarities are all greater than the preset threshold, it is judged that the video is played in a loop.
In this embodiment, a brightness curve of a video is plotted in units of a playing time period of the video, and the playing time period is described as an example of 10 minutes. After detecting that a video is played and a signal of a current signal source is stable, the duration obtaining unit 11 obtains the playing duration of the video according to detailed information of the video, and the curve drawing unit 12 starts to calculate the brightness of the video to draw a brightness curve. In order to ensure the accuracy and effectiveness of the brightness calculation, the playing time length is divided into a plurality of continuous time sections, the divided time sections are used as scales, and the average brightness in the time sections is used as the brightness corresponding to the time sections. N is a positive integer greater than or equal to 3; in another embodiment, the luminance corresponding to the end point or the start point of the time period may be set as the luminance corresponding to the time period, instead of the average luminance.
Hereinafter, the description will be given by taking 5 seconds as an example, and dividing 10 minutes into 120 time periods of 5 seconds. Acquiring all frame pictures of a video within 5 seconds, acquiring the brightness of each frame picture, adding the brightness of all the frame pictures within 5 seconds, dividing the total frame number within 5 seconds to obtain the average brightness value of the video within 5 seconds, acquiring 120 average brightness values of the video within 10 minutes in such a way, and drawing a brightness curve of the video within 10 minutes according to the 120 average brightness values.
In the above manner of plotting the luminance curves, 5 luminance curves were obtained, which were Y1, Y2, Y3, Y4, and Y5, respectively. With Y1 as a reference luminance curve, the similarity between the other luminance curves and the luminance curve is calculated, the similarity between Y2 and Y1 is Δ Y1, the similarity between Y3 and Y1 is Δ Y2, the similarity between Y4 and Y1 is Δ Y3, and the similarity between Y5 and Y1 is Δ Y4. And judging whether the obtained similarities delta Y1, delta Y2, delta Y3 and delta Y4 are all larger than a preset threshold value. Wherein, a threshold value of the similarity, for example, 90%, is preset, and the value is generally an empirical value obtained according to actual scene simulation. And when the N-1 similarity degrees are all judged to be larger than a preset threshold value, judging that the video is played circularly, otherwise, judging that the played video is not played circularly currently.
Further, in order to enhance the accuracy of the judgment, the judgment may be performed a plurality of times. That is, when it is detected that the similarity among the N-1 similarities is smaller than the preset threshold, the related luminance curve is discarded, and the luminance curves within the consecutive N playing time durations are obtained for judgment. For example, when detecting that Δ Y2 is smaller than the preset threshold, Y1, Y2 and Y3 are discarded, and then luminance curves Y6, Y7 and Y8 within 3 continuous playing time lengths after Y5 are acquired. Then, the similarity of the brightness curves is judged according to Y4, Y5, Y6, Y7 and Y8. The number of times of the multiple judgments can be preset according to needs.
If the video played by the television is the circular playing of the same video, if the brightness curve is drawn according to the playing time length of the video, the obtained difference between the continuous brightness curves is very small or even no difference, so that the obtained similarities can reach a preset threshold value, and if the video is not the circular playing of the same video, the difference between the obtained brightness curves is very large and is far lower than the preset threshold value.
Furthermore, in other embodiments, the similarity calculation unit 13 may also be configured to: and calculating the similarity of every two adjacent brightness curves in the N brightness curves.

The circular judgment module 10 judges whether the video is circularly played according to the playing duration and the brightness curve of the video in the above detection manner, if so, the current working place of the television is considered as a store, so that the television can be displayed with a better display effect and the television is prevented from entering a standby state without being operated for a long time, the mode switching module 20 controls the television to be switched to the store mode to operate, and after the television is switched to the store mode, the video can be played according to the preset parameters in the store mode and cannot enter the standby state even if the television is not operated for a long time.
The mode switching device of the television set provided by the embodiment judges whether the currently played video is played circularly according to the playing time length and the brightness curve of the video when the television set is detected to run in a home mode and the video is played, and controls the television set to be switched to a market mode to run if the currently played video is played circularly.

In this embodiment, a FLAG is set for the television, and when FLAG is equal to 1, the corresponding mode switching state is automatic switching, and when FLAG is equal to 0, the corresponding mode switching state is manual switching. When the television is shipped, the default FLAG value is 1. When the television is started for the first time, if it is detected that the television enters a home mode for operation and a video is played, the state acquisition module 30 may determine that the current mode switching state of the television is automatic switching according to FLAG being 1, and then execute a subsequent step of determining whether the video is played in a circulating manner.
