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.
In the prior art, a user can only select a video frame rate from existing video frame rates, but cannot dynamically adjust the video frame rate, and cannot meet the use requirements of the user.
Therefore, the invention provides a method for controlling the video frame rate of the smart television, which can effectively realize the dynamic adjustment of the video frame rate and meet the use requirements of users.
Referring to fig. 1, a schematic flow chart of a method for controlling a video frame rate of a smart television according to a first embodiment of the present invention includes:
step 101, acquiring data which is sensed by a motion sensor in slave equipment and meets preset conditions;
in the embodiment of the invention, the smart television can be connected with the slave equipment in a state of being started and normally working, and the slave equipment can send an instruction to the smart television so as to control the playing of the smart television. In the embodiment of the invention, the slave device has a video frame rate control function, and after the slave device starts the video frame rate control function, a user can control the video frame rate of the smart television by performing an operation on the slave device, wherein the operation may be a shaking operation.
The slave device is internally provided with a motion sensor, detects data sensed by the motion sensor in real time, and acquires the data meeting preset conditions if the data sensed by the motion sensor meets preset conditions. Specifically, the method comprises the following steps: and acquiring sensed sensing data from the motion sensor, acquiring a curve formed by the sensing data, and selecting data in a curve section of which the curve amplitude or frequency is greater than the preset amplitude or frequency as the data meeting the preset condition. The condition that the preset condition is met is that the amplitude or the frequency is larger than the preset amplitude or frequency. For example, when the user performs a shaking operation on the slave device, and the amplitude or frequency of the shaking operation is greater than a preset amplitude or frequency, the slave device will control the frame rate of the smart television based on data in a curve segment in which the amplitude or frequency is greater than the preset amplitude or frequency.
The slave device can be a mobile terminal with a motion sensor, such as a mobile phone, a PAD and the like, which are connected with the smart television through a network.
The motion sensor is an original element for converting the change of non-electric quantity (such as speed and pressure) into the change of electric quantity, and is a part and an accessory for measuring and controlling instruments and equipment.
In order to prevent the video frame rate of the smart television from being changed due to the unintentional operation of the user, a start gesture of the video frame rate control function may be set on the slave device or a start button may be set in a drop-down bar of the slave device display interface.
Step 102, determining a change value of a video frame rate according to data;
in the embodiment of the invention, after the data meeting the preset condition and sensed by the motion sensor is acquired, the change value of the video frame rate is determined according to the data.
The change value of the video frame rate may be a decrease value of the video frame rate or an increase value of the video frame rate, where the decrease value of the video frame rate indicates that a corresponding number of frame pictures needs to be deleted from the original video frame rate of the currently played video, and the increase value of the video frame rate indicates that a corresponding number of frame pictures needs to be added to the original video frame rate of the currently played video.
And 103, sending the change value of the video frame rate to the smart television, so that the smart television adjusts the video according to the change value of the video frame rate, and playing the video by using the adjusted video.
In the embodiment of the invention, after the change value of the video frame rate is determined, the slave device sends the change value of the video frame rate to the smart television, and after the smart television receives the change value of the video frame rate, the slave device adjusts the video according to the change value of the video frame rate and plays the video by using the adjusted video, so that the slave device dynamically adjusts and controls the video frame rate of the smart television.
If the frame rate of the currently played video is reduced, the fast playing is realized, and if the frame rate of the currently played video is increased, the slow playing is realized.
In the embodiment of the present invention, if the smart television receives an increased value of the video frame rate, the position of the increased video frame is determined according to the principle of uniform insertion based on the current video frame rate and the increased value of the video frame rate, and the previous frame video frame or the next frame video frame at the position is copied, and the copied video frame is inserted into the position to achieve the increase of the video frame, for example, if the current video frame rate is 60 frames, and the increased value of the video frame rate is 3, it may be determined that the video frame needs to be added between the 20 th frame and the 21 st frame, between the 40 th frame and the 41 th frame, and after the 60 th frame, and the 20 th frame is copied, the copied video frame is inserted between the 20 th frame and the 21 st frame, the 40 th frame is copied, the copied video frame is inserted between the 40 th frame and the 41 th frame, the 60 th frame is copied, and the copied video frame is placed after the 60 th frame.
If the smart television receives a reduced value of the video frame rate, determining the video frames to be deleted according to a uniform deletion rule based on the current video frame rate and the reduced value of the video frame rate to delete the video frame rate, for example, if the current video frame rate is 60 frames and the reduced value of the video frame rate is 4, determining that the 15 th frame, the 30 th frame, the 45 th frame and the 60 th frame need to be deleted, and deleting the frames.
In the embodiment of the invention, data which is sensed by a motion sensor in the slave equipment and meets the preset condition is acquired, the change value of the video frame rate is determined according to the data, and the change value of the video frame rate is sent to the smart television, so that the smart television adjusts the video according to the change value of the video frame rate and plays the video by using the adjusted video. The slave device obtains the data meeting the preset conditions, obtains the change value of the video frame rate based on the data, and sends the change value to the smart television, so that the dynamic adjustment of the frame rate of the smart television can be effectively realized, the use requirements of users are met, and the users can execute the operation on the slave device to enable the data sensed by the motion sensor to meet the preset conditions, so that the control of the frame rate of the smart television is realized, the interestingness is enhanced, and the user experience is improved.
Referring to fig. 2, a flowchart of a step 102 of the first embodiment of the present invention is shown, which includes:
step 201, counting a first number of times of paired occurrence of wave crests and wave troughs in a preset first time period and a second number of times of paired occurrence of wave crests and wave troughs in a preset second time period according to data, wherein the duration of the first time period is less than that of the second time period;
in the embodiment of the invention, after the slave device acquires the data meeting the preset condition, the number of times of paired occurrence of wave crests and wave troughs in the preset first time period and the preset second time period is counted according to the data. And the duration of the first time period is less than that of the second time period. Specifically, the method comprises the following steps: the slave device may establish two threads, a first thread processes data obtained from the data in a preset first time period and determines a first number of times that peaks and troughs appear in the data in the first time period, a second thread obtains data in a preset second time period from the data and determines a second number of times that peaks and troughs appear in the data in the second time period, for example, if the first time period is 10ms, the first thread of the slave device obtains data of a duration of 10ms satisfying a preset condition from a motion sensor, processes the data of the duration of 10ms by the first thread, and determines a first number of times that peaks and troughs appear in pairs in the 10 ms. And if the second time period is 1s, acquiring data of 1s time length meeting preset conditions from the motion sensor by a second thread in the slave device, processing the data in the 1s time length by the second thread, and determining a second frequency of paired occurrence of wave peak and wave trough in the 1 s.
Step 202, determining a variation value of the video frame rate according to the data, the first times and the second times.
In the embodiment of the invention, after the first time and the second time are acquired, the slave device determines the change value of the video frame rate according to the data meeting the preset condition, the first time and the second time. Specifically, there are several cases as follows:
if the first time is less than the first preset time, processing the data with the decreasing negative value in the first time period in the data, and determining the decreasing value of the video frame rate;
if the second time is greater than or equal to the first preset time, determining an increase value of the video frame rate according to data with increasing positive values in the data within a second time period;
and if the first time is greater than or equal to the first preset time, or if the second time is less than the first preset time, determining that the change value of the video frame rate is a preset value.
In the embodiment of the invention, the first time and the second time are independently processed by two threads, and when the first time is determined to be less than a first preset time, the slave device processes data with a decreasing negative value in a first time period to determine a reduction value of the video frame rate.
Wherein, the data with decreasing negative value in the first time period can be determined as follows: determining all the wave valley values of the acquired data in the first time period, calculating the average value of all the wave valley values, and determining the average value from 0 to the average value as data with a decreasing negative value in the first time period. For example, if the acquired data have a valley value of-12, -9, -8, -11 in the first time period, respectively, the average value is determined to be-10, indicating that the data with decreasing negative values range from 0 to-10. Alternatively, the data with decreasing negative values in the first time period may also be determined as follows: determining all the wave bottom values of the acquired data in a first time period, and taking the maximum value from 0 to all the wave bottom values as data with a decreasing negative value in the first time period, or taking the minimum value from 0 to all the wave bottom values as data with a decreasing negative value in the first time period. For example: if the valley values of the acquired data in the first time period are-12, -9, -8, -11, respectively, the decreasing negative value is determined to be in the range of 0 to-12, or 0 to-8. In practical applications, the determination manner of the data with decreasing negative values in the first time period may be set according to specific needs, which is not limited here.
The determining the reduction value of the video frame rate based on the data with decreasing negative values in the first time period specifically includes: and dividing the difference value between the maximum value and the minimum value in the data with the decreasing negative value by a preset value, wherein the calculated result is the reduction value of the video frame rate. For example, the data with decreasing negative values is 0 to-15, the difference between the minimum value and the maximum value in the data with decreasing negative values is 15, the difference is divided by a preset value of 5 for 15, and the calculated result is 3, which is the reduction value of the video frame rate. And if the calculation result is not an integer, determining a maximum integer smaller than the calculation result or a minimum integer larger than the calculation result or an integer determined in a rounding manner according to the calculation result as the reduction value of the video frame rate. For example, if the obtained calculation result is 3.4, it is determined that the reduction value of the video frame rate is 3 or 4.
In the embodiment of the invention, when the second number is greater than or equal to the first preset number, processing is performed according to data with increasing positive values in the second time period in the acquired data, and the increase value of the video frame rate is determined.
Wherein the data with increasing positive values in the second time may be determined as follows: determining all the wave peak values of the acquired data in the second time period, calculating an average value of all the wave peak values, and determining that the average value to 0 is data with increasing positive values in the second time period, for example, if the wave peak values of the acquired data in the second time period are respectively 15, 14, 13, 14 and 14, determining that the average value of the wave peaks is 14, and determining that the data with increasing positive values is 0 to 14. Alternatively, the data with increasing positive values in the second time period may also be determined as follows: and determining all wave peak values of the acquired data in the second time period, and taking the maximum value from 0 to all the wave peak values as data with increasing positive values in the second time period, or taking the minimum value from 0 to all the wave peak values as data with increasing positive values in the second time period. For example, if the peak values of the acquired data in the second time period are 15, 14, 13, 14, and 14, respectively, the data in which the positive values in the second time period are incremented is determined to be 0 to 13, or 0 to 15.
The determining of the increased value of the video frame rate based on the data with the increasing positive value in the second time period specifically includes: and dividing the difference value between the maximum value and the minimum value in the data with the increasing positive value by a preset value, wherein the calculated result is the increased value of the video frame rate. For example, the second data with increasing positive values is 0 to 15, the difference between the maximum value and the minimum value in the data with increasing positive values is 15, the difference is divided by a preset value of 5 for 15, and the calculated result is the increased value of the video frame rate. And if the result of the calculation is not an integer, determining a maximum integer smaller than the result of the calculation or a minimum integer larger than the result of the calculation or an integer determined in a rounding manner as a reduction value of the video frame rate according to the result of the calculation, for example, if the result of the calculation is 4.5, determining an increase value of the video frame rate to be 4 or 5.
In the embodiment of the present invention, when the first number is greater than or equal to the first preset number, or if the second number is less than the first preset number, it is determined that the operation of the user is an invalid operation, and it is determined that the change value of the video frame rate is a preset value, where the preset value is preferably 0.
Or,
in this embodiment of the present invention, the determining, by the slave device, the change value of the video frame rate according to the data satisfying the preset condition, the first number of times, and the second number of times may specifically be: and judging whether the first time is greater than or equal to a third preset time, if so, determining a reduction value of the video frame rate according to the second time, and if the first time is less than the third preset time, determining an increase value of the video frame rate according to the second time.
For example, when the first number is 6 and the second number is 8, if the third preset number is 9, it may be determined that the first number is 6 smaller than the third preset number 9, and the increased value of the video frame rate is determined according to the second number, specifically, the second number 8 may be multiplied by a preset coefficient to obtain an increased value of the video frame rate, and if the preset coefficient is 0.5, the increased value of the video frame rate is 4. Or, if the third preset number is 5, it may be determined that the first number 6 is greater than the third preset number 5, and a decrease value of the video frame rate is determined according to the second number, specifically, the second number 8 may be multiplied by a preset coefficient to obtain an increase value of the video frame rate, and if the preset coefficient is 1, the decrease value of the video frame rate is 8.
In the embodiment of the invention, the requirement of the user on fast playing is greater than that of slow playing, and whether the fast playing is required or not can be determined in a short time by the first number of times of appearance of the wave crests and the wave troughs in the first time period so as to quickly meet the requirement of the user.
In the embodiment of the invention, the first times of paired appearance of wave peaks and wave troughs in the preset first time period and the second times of paired appearance of wave peaks and wave troughs in the preset second time period are counted according to data, and the data, the first times and the second times are utilized to determine the change value of the video frame rate, so that the adjustment of the frame rate of the smart television can be realized based on the change value of the video frame rate.
Referring to fig. 3, a flowchart of a step 102 of the first embodiment of the present invention is shown, which includes:
step 301, counting a third number of times of paired peak and valley in a preset third time period according to data;
step 302, if the third time is greater than or equal to a second preset time, acquiring an end value sensed by the motion sensor at an end time point of the third time period;
in the embodiment of the invention, after the slave device acquires the data meeting the preset condition, the third times of paired occurrence of peaks and troughs is counted according to the data.
If the third time of the paired appearance of the wave crests and the wave troughs is greater than or equal to the second preset time, the operation of the user is effective, and the slave device acquires an end value sensed by the motion sensor at the end time point of the third time period, for example, if the length of the third time period is 30ms, the end time point of the third time period is 30 ms. And if the number of times of paired occurrence of the wave crests and the wave troughs is less than a second preset number of times, the operation of the user is invalid.
Preferably, the third time period may be a time period formed by the continuous data satisfying the preset condition in time.

In the embodiment of the present invention, after acquiring the end value sensed by the motion sensor at the end time point of the third time period, if the end value is greater than the preset value, the decrease value of the video frame rate is determined according to the end value, which may specifically be: and dividing the ending value by a preset constant, and taking the obtained quotient value as a reduction value of the video frame rate. If the ending value is smaller than the preset value, determining the video frame rate increase value according to the ending value, which may specifically be: and dividing the absolute value of the ending value by a preset constant, and taking the obtained quotient as the added value of the video frame rate. For example, an end value sensed by the motion sensor at the end time point of the third time period is obtained as 12, the end value is greater than a preset value of 8, the end value is divided by a preset constant of 4, and 3 is calculated, that is, the reduction value of the video frame rate is 3.

If the fourth time is less than the fourth preset time, determining that the change mode of the video frame rate is the video frame rate reduction, and determining the reduction value of the video frame rate according to the average value of the amplitudes of each pair of peaks and troughs. It should be noted that, the above is only one possible way to determine the variation value of the video frame rate based on the fourth number, the fourth preset number and the average value of the amplitudes of each pair of peaks and troughs, and other ways may also be used in practical applications. For example: step 402 may also be: if the fourth number is greater than or equal to the fourth preset number, determining that the change mode of the video frame rate is the video frame rate reduction, determining the reduction value of the video frame rate according to the average value of the amplitudes of each pair of wave crests and wave troughs, if the fourth number is less than the fourth preset number, determining that the change mode of the video frame rate is the video frame rate increase, and determining the increase value of the video frame rate according to the average value of the amplitudes of each pair of wave crests and wave troughs.

Referring to fig. 7, a detailed functional block diagram of the first determining module 602 according to the third embodiment of the present invention includes a first counting module 701 and a second determining module 702.
The first statistical module 701 is configured to count, according to data, a first number of paired occurrences of peaks and troughs in a preset first time period and a second number of paired occurrences of peaks and troughs in a preset second time period, where a duration of the first time period is less than a duration of the second time period;
in the embodiment of the present invention, after acquiring data meeting a preset condition, the first statistical module 701 counts the number of paired occurrences of peaks and troughs in a preset first time period and a preset second time period according to the data. And the duration of the first time period is less than that of the second time period. Specifically, the method comprises the following steps: the slave device may establish two threads, a first thread processes data obtained from the data in a preset first time period and determines a first number of times that peaks and troughs appear in the data in the first time period, a second thread obtains data in a preset second time period from the data and determines a second number of times that peaks and troughs appear in the data in the second time period, for example, if the first time period is 10ms, the first thread of the slave device obtains data of a duration of 10ms satisfying a preset condition from a motion sensor, processes the data of the duration of 10ms by the first thread, and determines a first number of times that peaks and troughs appear in pairs in the 10 ms. And if the second time period is 1s, acquiring data of 1s time length meeting preset conditions from the motion sensor by a second thread in the slave device, processing the data in the 1s time length by the second thread, and determining a second frequency of paired occurrence of wave peak and wave trough in the 1 s.
A second determining module 702, configured to determine a change value of the video frame rate according to the data, the first number of times, and the second number of times.
In this embodiment of the present invention, after the first number and the second number are obtained, the second determining module 702 determines the change value of the video frame rate according to the data meeting the preset condition, the first number and the second number. Specifically, there are several cases as follows:
if the first time is less than the first preset time, the second determining module 702 processes the data with decreasing negative value in the data within the first time period, and determines a decreasing value of the video frame rate;
if the second number is greater than or equal to the first preset number, the second determining module 702 determines the increased value of the video frame rate according to the data with the increased positive value in the second time period in the data;
if the first number is greater than or equal to the first preset number, or if the second number is less than the first preset number, the second determining module 702 determines that the change value of the video frame rate is a preset value.
In this embodiment of the present invention, the first number and the second number are processed by two threads independently, and when the first thread determines that the first number is smaller than the first preset number, the second determining module 702 processes data with decreasing negative values in the first time period, and determines a reduction value of the video frame rate.
Wherein, the data with decreasing negative value in the first time period can be determined as follows: determining all the wave valley values of the acquired data in the first time period, calculating the average value of all the wave valley values, and determining the average value from 0 to the average value as data with a decreasing negative value in the first time period. For example, if the acquired data have a valley value of-12, -9, -8, -11 in the first time period, respectively, the average value is determined to be-10, indicating that the data with decreasing negative values range from 0 to-10. Alternatively, the data with decreasing negative values in the first time period may also be determined as follows: determining all the wave bottom values of the acquired data in a first time period, and taking the maximum value from 0 to all the wave bottom values as data with a decreasing negative value in the first time period, or taking the minimum value from 0 to all the wave bottom values as data with a decreasing negative value in the first time period. For example: if the valley values of the acquired data in the first time period are-12, -9, -8, -11, respectively, the decreasing negative value is determined to be in the range of 0 to-12, or 0 to-8. In practical applications, the determination manner of the data with decreasing negative values in the first time period may be set according to specific needs, which is not limited here.
The determining the reduction value of the video frame rate based on the data with decreasing negative values in the first time period specifically includes: and dividing the difference value between the maximum value and the minimum value in the data with the decreasing negative value by a preset value, wherein the calculated result is the reduction value of the video frame rate. For example, the data with decreasing negative values is 0 to-15, the difference between the minimum value and the maximum value in the data with decreasing negative values is 15, the difference is divided by a preset value of 5 for 15, and the calculated result is 3, which is the reduction value of the video frame rate. And if the calculation result is not an integer, determining a maximum integer smaller than the calculation result or a minimum integer larger than the calculation result or an integer determined in a rounding manner according to the calculation result as the reduction value of the video frame rate. For example, if the obtained calculation result is 3.4, it is determined that the reduction value of the video frame rate is 3 or 4.
In this embodiment of the present invention, when the second number is greater than or equal to the first preset number, the second determining module 702 performs processing according to data that is obtained in a second time period and has an increasing positive value, and determines an increase value of the video frame rate.
Wherein the data with increasing positive values in the second time may be determined as follows: determining all the wave peak values of the acquired data in the second time period, calculating an average value of all the wave peak values, and determining that the average value to 0 is data with increasing positive values in the second time period, for example, if the wave peak values of the acquired data in the second time period are respectively 15, 14, 13, 14 and 14, determining that the average value of the wave peaks is 14, and determining that the data with increasing positive values is 0 to 14. Alternatively, the data with increasing positive values in the second time period may also be determined as follows: and determining all wave peak values of the acquired data in the second time period, and taking the maximum value from 0 to all the wave peak values as data with increasing positive values in the second time period, or taking the minimum value from 0 to all the wave peak values as data with increasing positive values in the second time period. For example, if the peak values of the acquired data in the second time period are 15, 14, 13, 14, and 14, respectively, the data in which the positive values in the second time period are incremented is determined to be 0 to 13, or 0 to 15.
The determining of the increased value of the video frame rate based on the data with the increasing positive value in the second time period specifically includes: and dividing the difference value between the maximum value and the minimum value in the data with the increasing positive value by a preset value, wherein the calculated result is the increased value of the video frame rate. For example, the second data with increasing positive values is 0 to 15, the difference between the maximum value and the minimum value in the data with increasing positive values is 15, the difference is divided by a preset value of 5 for 15, and the calculated result is the increased value of the video frame rate. And if the result of the calculation is not an integer, determining a maximum integer smaller than the result of the calculation or a minimum integer larger than the result of the calculation or an integer determined in a four-round-five-in manner as a reduction value of the video frame rate according to the result of the calculation, for example, if the result of the calculation is 4.5, determining an increase value of the video frame rate to be 4 or 5.
In this embodiment of the present invention, when the first number is greater than or equal to the first preset number, or if the second number is less than the first preset number, it is determined that the operation of the user is an invalid operation, and the second determining module 702 determines that the change value of the video frame rate is a preset value, where the preset value is preferably 0.
Or,
in this embodiment of the present invention, the determining, by the second determining module 702, the change value of the video frame rate according to the data meeting the preset condition, the first number of times and the second number of times may specifically be: and judging whether the first time is greater than or equal to a third preset time, if so, determining a reduction value of the video frame rate according to the second time, and if the first time is less than the third preset time, determining an increase value of the video frame rate according to the second time.
For example, when the first number is 6 and the second number is 8, if the third preset number is 9, it may be determined that the first number is 6 smaller than the third preset number 9, and the increased value of the video frame rate is determined according to the second number, specifically, the second number 8 may be multiplied by a preset coefficient to obtain an increased value of the video frame rate, and if the preset coefficient is 0.5, the increased value of the video frame rate is 4. Or, if the third preset number is 5, it may be determined that the first number 6 is greater than the third preset number 5, and a decrease value of the video frame rate is determined according to the second number, specifically, the second number 8 may be multiplied by a preset coefficient to obtain an increase value of the video frame rate, and if the preset coefficient is 1, the decrease value of the video frame rate is 8.
In the embodiment of the invention, the requirement of the user on fast playing is greater than that of slow playing, and whether the fast playing is required or not can be determined in a short time by the first number of times of appearance of the wave crests and the wave troughs in the first time period so as to quickly meet the requirement of the user.
In the embodiment of the invention, the first times of paired occurrence of the wave peaks and the wave troughs in the preset first time period and the second times of paired occurrence of the wave peaks and the wave troughs in the preset second time period are counted according to the data, and the change value of the video frame rate is determined by utilizing the data, the first times and the second times, so that the adjustment of the video frame rate of the currently played video of the smart television can be realized based on the change value of the video frame rate.
