In order to make the purpose, technical solution and beneficial effects of the present application more clear and more obvious, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

In the embodiment of the application, a plurality of videos are displayed on a user interface, such as the video 104 in fig. 1, a user may select a video to be played through a remote controller, first select the video to be played through a cursor 105 of the smart television controlled by the remote controller 102, and then output a signal through a key on the remote controller to turn on the video to be played. Or, the user can also select the video to be played through the terminal device. And then playing the video to be played. The video can be tuned by two optional tuning modes through two tuning devices during playing.
In the first optional tuning mode, the terminal device 103 sends a volume coefficient adjustment command to the smart television 101, where the volume coefficient adjustment command includes a target volume coefficient, and the smart television adjusts the current playing volume of the video to be played according to the target volume coefficient.
In a second optional tuning mode, the remote controller 102 sends an infrared signal to the smart television 101 when tuning, the infrared signal includes key values, different key values represent different key information, and the volume is adjusted by the remote controller every time, and the current playing volume of the video to be played is increased or decreased by one.
For example, the current playing volume of a video to be played is 10, a user sends continuous infrared signals to the smart television through the remote controller, the key value in each sent infrared signal is that the volume is increased by one, and the current playing volume is increased by one unit every time the smart television receives the infrared signal containing the volume increased by one, so that the target playing volume of the user is finally reached.
Fig. 2 exemplarily shows a schematic structural diagram of a device for volume control of a smart television, where as shown in fig. 2, the smart television includes a browser module 201, a user interface module 202, and a control module 203. In the first tuning with the terminal device, in an optional embodiment, when the user tunes through the terminal device, the browser module 201 of the smart television performs volume adjustment according to the received target volume factor.
In the second tuning with the remote controller, in an optional implementation manner, when the user tunes with the remote controller, the user interface module 202 of the smart television performs adjustment according to the received infrared signal containing the key value of the remote controller.
The terminal device 103 may be a communication device capable of communicating with the smart television, such as a mobile phone, a tablet computer, and a personal computer.
Fig. 3 shows a flowchart of a method for volume control of a smart television according to an embodiment of the present application, where as shown in fig. 3, the method may include:
In the embodiment of the application, the current playing volume of the smart television is determined, the volume coefficient of a video to be played is obtained, the initial playing volume of the video to be played is determined according to the volume coefficient of the video to be played and the current playing volume of the smart television, and the difference value between the initial playing volume of the video to be played and the current playing volume of the smart television is smaller than a preset threshold value. And playing the video to be played at the initial playing volume of the video to be played. Due to the fact that the difference between the initial playing volume of the video to be played and the current playing volume of the smart television before the video to be played is small, the problem that the volume jumps when the smart television plays the video can be solved.
In step 301, in an optional implementation manner, the browser module of the smart television may send a current playing volume query request to the control module of the smart television, the control module of the smart television obtains the current playing volume and then sends the current playing volume to the browser module, and the browser module of the smart television may further obtain the current playing volume of the smart television through detection.
In an optional embodiment, the determined current playing volume of the smart television refers to the system volume of the smart television, and the smart television may be currently playing videos or television programs, or may not play any videos or television programs. If the smart television is currently playing the video or the television program, the current playing volume of the smart television is also the playing volume of the video or the television program currently played by the smart television. If the smart television does not play the video or the television program at present, the current playing volume of the smart television is the system volume of the smart television, and the volume may be the playing volume of the last video or television program played by the smart television or the system volume of the smart television, which is obtained after the user adjusts the playing volume of the smart television last time. Alternatively, the television program may be a conventional television program played by the smart television after receiving the broadcast signaling.
In the step 302, there are multiple ways to obtain the volume coefficient of the video to be played, in an optional implementation, the browser module of the smart television may obtain the volume coefficient of the video to be played from the control module of the smart television, and after the smart television determines the video to be played through a remote controller or a terminal device, the volume coefficient is obtained from the control module of the smart television, and the volume coefficient in this way may be a historical volume coefficient of the video to be played watched on the same smart television.
In another alternative embodiment, the browser module of the smart television may be obtained from a server that provides the video to be played. After the smart television determines a video to be played through a remote controller or terminal equipment, a browser module of the smart television sends a playing request to a server providing the video to be played, the playing request comprises an identifier of the video to be played, and after the server receives the playing request, the server sends a volume coefficient of the video to be played to the smart television according to the identifier of the video to be played. The volume coefficient provided by the server may be manually set by a worker at the server, and the volume coefficient of the video to be played may also be determined according to all the volume coefficients fed back by the terminal that has played the video to be played, for example, an average value of all the fed back volume coefficients is obtained, and the average value of the volume coefficients fed back by all the terminals within a preset time period may also be obtained as the volume coefficient provided by the server to the smart television.
After step 302 and before step 303, in an alternative embodiment, after the smart tv acquires the volume coefficient of the video to be played, the smart tv is further triggered to generate an initialization symbol, such as a number "1", where the initialization symbol indicates that the initial playing volume of the video to be played is not obtained according to the volume coefficient after the smart tv acquires the volume coefficient.
After step 302 and before step 303, in an optional implementation manner, the smart television may determine a volume coefficient of the obtained video to be played, and when the value of the volume coefficient is greater than 0, the browser module of the smart television sends a mute instruction to the play channel of the smart television, that is, the play channel is in a non-mute state. When the value of the volume coefficient is equal to 0, the playing channel is in a mute state, and at this time, after the smart television has to receive a mute instruction, for example, the smart television receives the mute instruction sent by the terminal device or the remote controller, the value of the volume coefficient is not equal to 0, so that the playing channel of the smart television is not in the mute state.
In an optional implementation manner, the browser module of the smart television may determine the reference volume of the video to be played according to a quotient of a current playing volume of the smart television and a volume coefficient of the video to be played.
In a scheme for determining the reference volume, a quotient of a current playing volume of the smart television and a volume coefficient of a video to be played may be subjected to some operations, for example, the quotient is multiplied by a weight to obtain the reference volume of the video to be played. The weight may be preset, such as by a user setting empirically.
In another scheme for determining the reference volume, the quotient of the current playing volume of the smart television and the volume coefficient of the video to be played is directly used as the reference volume. Alternatively, the reference volume may be determined according to equation (1):
in formula (1), P is the current playing volume of the smart television, B is the volume coefficient of the video to be played, and a is the reference volume.
In the embodiment of the application, the browser module of the smart television can determine the initial playing volume of the video to be played according to the product of the reference volume and the volume coefficient of the video to be played.
In a scheme for determining the initial play volume of a video to be played, some operations may be performed on the product of a reference volume and a volume coefficient of the video to be played, for example, the result is multiplied by a weight, so as to obtain the initial play volume of the video to be played. The weight may be preset, such as by a user setting empirically.
In another scheme for determining the initial playing volume of the video to be played, the product of the reference volume and the volume coefficient of the video to be played is directly used as the initial playing volume of the video to be played. Alternatively, the initial playing volume of the video to be played may be determined according to formula (2):
P0formula (2) of a × B … …
In formula (2), a is a multiple number, a is a reference volume, B is a volume coefficient of a video to be played, and P is0And the initial playing volume of the video which is not to be played.
In the prior art, the problem of volume jump occurs in the playing process of the smart television. For example, the playing volume of a video currently played by the smart television is 20, that is, the current playing volume of the smart television is 20, the user turns on another video after turning off the video, and after obtaining the volume coefficient 0.5 of the another video, the playing volume of the another video is recalculated by multiplying the current playing volume of the smart television 20 by the volume coefficient 0.5 of the another video to obtain the playing volume of the another video as 10, in which case, the smart television plays the another video at the playing volume of 10. It can be seen that the user switches from one video to another video, the playing volume of the smart television jumps from 20 to 10, but the user does not adjust the volume of the smart television.
In the embodiment of the application, the browser module of the smart television acquires that the volume coefficient of the video to be played is 0.5 from the server, and the determined current playing volume is 15, so that the reference volume of the video to be played is 30 according to the quotient of the current playing volume 15 of the smart television and the volume coefficient 0.5 of the video to be played, and then the initial playing volume of the video to be played is determined to be 15 according to the product of the reference volume 30 and the volume coefficient 0.5 of the video to be played. And the smart television plays the video to be played according to the determined initial playing volume 15 of the video to be played as the current playing volume of the video to be played. Therefore, the current playing volume of the smart television before the video to be played is the same as the initial playing volume of the video to be played, and no volume jump occurs.
In the above example, the current playing volume is the same as the initial playing volume of the video to be played, in an alternative embodiment, a quotient between the current playing volume of the smart television and the volume coefficient of the video to be played may be divided by a factor of two, and a mode of keeping a decimal number is adopted.
In an optional implementation manner, the browser module of the smart television may store the initial playing volume and the reference volume of the video to be played, and may also send the initial playing volume and the reference volume of the video to be played to the control module of the smart television for storage.
In an optional implementation manner, after the smart television plays the video to be played according to the initial playing volume of the video to be played, the initialization symbol changes from a digital "1" to a digital "0".
Fig. 4 shows a flowchart of a method for volume control of a smart television according to an embodiment of the present application, where as shown in fig. 4, the method may include:
in step 409, the intelligent television changes the initialization symbol.
After the step 304 or the step 409, the user may adjust the volume of the video to be played in the playing process in two ways, where the first way is that the user sends a target volume coefficient to the smart television through the terminal device, and the second way is that the user sends an infrared signal containing a key value to the smart television through the remote controller. And the intelligent television adjusts the playing volume according to the received target volume coefficient or the infrared signal containing the key value.
Fig. 5 shows a flowchart of a method for volume control of a smart television according to an embodiment of the present application, where as shown in fig. 5, the method may include:
step 504, determining a first target playing volume according to the updated reference volume and the target volume coefficient;
and step 505, playing the video to be played at the first target playing volume.
In step 501, the volume coefficient adjustment command may be sent by the terminal device to the browser module of the smart television.
In step 502, in an optional implementation manner, if the video to be played has been subjected to volume adjustment at least once after starting to be played in a manner of receiving a volume coefficient adjustment command, the historical playing volume is the playing volume of the video to be played after the volume of the video to be played has been adjusted recently according to the received volume coefficient adjustment command; if the volume adjustment is not performed after the video to be played starts to be played in a mode of receiving the volume coefficient adjustment command, the historical playing volume is the initial playing volume.
Specifically, if the volume adjustment is performed at least once after the video to be played starts to be played in a manner of receiving a volume coefficient adjustment command, that is, in a manner of tuning the terminal device, the historical playing volume of the video to be played is the current playing volume of the video to be played after the volume adjustment; if the volume adjustment is not performed in the manner of receiving the volume coefficient adjustment command after the video to be played starts to be played, that is, the volume adjustment is not performed in any manner or is performed once through a remote controller, the historical playing volume of the video to be played is the initial playing volume of the played video to be played.
In step 503, in an optional implementation manner, the browser module of the smart television updates the value of the reference volume according to the current playing volume of the video to be played and the historical playing volume of the video to be played, so as to obtain the updated reference volume.
For example, if the current playing volume is adjusted by the remote controller for the first time, the historical playing volume of the video to be played is the initial playing volume of the volume to be played during playing, when the volume of the smart television is adjusted by the terminal device for the second time, the current playing volume of the video to be played is the playing volume adjusted by the remote controller for the last time, the current playing volume of the video to be played is not equal to the historical playing volume of the video to be played, and the browser module of the smart television updates the value of the reference volume according to the current playing volume of the video to be played and the historical playing volume of the video to be played, so as to obtain the updated reference volume.
In an optional implementation manner, the browser module of the smart television determines that a quotient of a product of a current playing volume of the video to be played and the reference volume and a historical playing volume of the video to be played is the updated reference volume. Optionally, the updated reference volume is determined according to equation (3):
in formula (3), a is a multiplication number, a is a reference volume, and P is1Is the current playing volume, P, of the video to be played0For historical playing volume of the video to be played, A1Is the updated reference volume.
In the step 504, in an optional implementation manner, after the browser module of the smart television determines the updated reference volume, the first target play volume may be determined according to the updated reference volume and the target volume coefficient. When the target volume coefficient is tuned through the terminal equipment for the second time, the user sends the target volume coefficient to the smart television through the terminal equipment. Optionally, the first target playing volume may be obtained according to a product of the updated reference volume and the target volume coefficient. Alternatively, the first target playback volume may be determined according to equation (4):
P2＝A1B1… … formula (4)
In formula (4), is a multiplication number, B1Is a target volume coefficient, A1Is the updated reference volume; p2The volume is played for the first target.
After the browser module of the smart television adjusts the volume through the terminal device to obtain the first target play volume, in an optional implementation manner, the value of the historical play volume may be updated by using the first target play volume, and the updated historical play volume is the first target play volume.
In an optional implementation manner, if it is determined that the current play volume of the video to be played is the same as the historical play volume, the second target play volume is determined according to the reference volume and the target volume coefficient. And playing the video to be played at the second target playing volume.
In an optional implementation manner, after the browser module of the smart television obtains the initial playing volume, the user adjusts the volume for the first time in a terminal device tuning manner, that is, the user sends the target volume coefficient to the smart television through the terminal device. Then the historical playing volume of the video to be played is the initial playing volume of the video to be played. At this time, the current playing volume of the video to be played during playing is the initial playing volume of the video to be played, so that the current playing volume of the video to be played during playing is the same as the historical playing volume of the video to be played, and the reference volume is not changed. Optionally, the browser module of the smart television determines the second target playing volume according to the reference volume and the target volume coefficient. In an alternative embodiment, the second target playback volume is a product of the reference volume and the target volume coefficient, and optionally, the second target playback volume may be determined according to equation (5):
P3＝A*B2… … formula (5)
In formula (5), a is a reference volume; b is2Is the target volume coefficient, multiplied by the number, P3Is the second target volume.
And after the browser module of the smart television determines the second target playing volume, playing the video to be played at the second target playing volume. And meanwhile, obtaining the updated historical playing volume of the video to be played according to the second target playing volume, wherein the updated historical playing volume of the video to be played is the second target playing volume.
Fig. 6 shows a flowchart of a method for volume control of a smart television according to an embodiment of the present application, where as shown in fig. 6, the method may include:
Fig. 7 shows a flowchart of a method for volume control of a smart television according to an embodiment of the present application, where as shown in fig. 7, the method may include:
703, comparing the historical playing volume of the video to be played with the current playing volume of the video to be played by a browser module of the smart television under the condition that the smart television is not tuned by a remote controller;
In an optional implementation manner, after receiving a target volume coefficient, such as a first target volume coefficient or a second target volume coefficient, sent by a terminal device, the smart television sends the target volume coefficient to a server providing a video to be played, so that the server serves as a reference when providing the volume coefficients for other smart televisions.
Based on the values of the above example, the reference volume is 30, the initial play volume is 15, and the history play volume is 15, for example:
example one: and after the initial playing volume of the intelligent television is obtained, tuning is carried out for the first time through the remote controller, and tuning is carried out for the second time through the terminal equipment.
After tuning is performed through the remote controller for the first time, the user interface module of the smart television determines that the current playing volume of the video to be played in playing is 24 according to the received infrared signal containing the key value, then plays the video to be played according to the current playing volume 24 of the video to be played, and sends the current playing volume of the video to be played to the control module of the smart television.
After the terminal device is tuned for the second time, the browser module of the smart television receives the first target volume coefficient 0.8 sent by the terminal device, sends the first target volume coefficient to the server, and compares the historical playing volume 15 of the video to be played with the current playing volume 24 of the video to be played. Because the historical playing volume of the video to be played is different from the current playing volume of the video to be played, the browser module of the smart television needs to recalculate the reference volume, and the updated reference volume, that is, 24 × 30/15 — 48, is obtained by the quotient of the product of the current playing volume of the video to be played and the reference volume and the historical playing volume. Then, the first target playing volume 48 × 0.8 is obtained as 38.4 according to the updated reference volume 48 and the first target volume coefficient 0.8, and the historical playing volume of the video to be played is updated to be 38.4 according to the first target playing volume. And then, the browser module of the smart television sends the first target playing volume, the historical playing volume of the video to be played and the updated reference volume to a control layer of the smart television. Therefore, the intelligent television recalculates the reference volume after the volume is adjusted through the remote controller, so that a subsequent user can directly adjust the volume up or down based on the updated reference volume through the terminal equipment tuning mode.
Example two: and after the initial playing volume of the intelligent television is obtained, tuning is carried out for the first time through the terminal equipment.
After the browser module of the smart television receives the second target volume coefficient 0.6 sent by the terminal device, because the historical playing volume of the video to be played and the current playing volume of the video to be played are both the same as the initial playing volume of the video to be played, the browser module of the smart television can obtain the second target playing volume 30 × 0.6 ═ 18 according to the reference volume and the second target volume coefficient, and obtain the updated historical playing volume of the video to be played according to the second target playing volume. And then, the browser module of the smart television sends the second target playing volume and the historical playing volume of the video to be played to a control layer of the smart television.
In another alternative implementation provided in this embodiment of the present application, step 504 in fig. 5 may be executed after step 602 in fig. 6, that is, after the current playing volume of the video to be played is obtained through tuning by the remote controller, an updated reference volume is directly obtained according to the current playing volume, the reference volume, and the historical playing volume of the video to be played,
for example, before tuning through the remote controller, the current playing volume of the video to be played is 15, the reference volume of the video to be played is 30, and when tuning through the remote controller for the first time obtains the current playing volume 24 of the video to be played, the updated reference volume 24 × 30/15 is obtained as 48 according to the quotient of the product of the current playing volume and the reference volume of the video to be played and the historical playing volume.
Optionally, the smart television may obtain an updated reference volume each time the smart television receives a red-out signal containing the key value.
