Description

Volume adjusting method and device and terminal

Technical Field

The invention relates to the technical field of terminal interaction, in particular to a volume adjusting method, a volume adjusting device and a terminal.

Background

With the continuous development of the smart television, the multi-screen interaction function between the mobile terminal and the smart television is also endless. At present, a mode for implementing a multi-screen interaction function is mainly to push an image on a mobile terminal, such as a video picture played by third-party software, to an intelligent television for playing through a DLNA (Digital Living Network Alliance) protocol, so as to implement media sharing between different terminals.

The DLNA protocol not only supports the media resources stored in the terminal to be pushed to other terminals for playing, but also supports the control of the playing state of the media resources on other terminals, such as playing pause, volume adjustment, and the like. The DLNA standard specifies two volume-related interactive commands: GetVolume and SetVolume; the Getvolume is an instruction for the mobile terminal to receive the volume of the television terminal, and the Setvolume is an instruction for the mobile terminal to set the volume of the television terminal. Generally, the process of adjusting the volume of a television set through the DLNA protocol is as follows: the method comprises the steps that a mobile terminal sends a Getvolume instruction to a television terminal, the television terminal feeds back the current volume of the television terminal to the mobile terminal, and the mobile terminal adjusts on the basis of the current volume of the television terminal to obtain the target volume; and the mobile terminal sends a Setvolume instruction to the television terminal, carries the target volume and adjusts the volume according to the target volume.

However, at present, many third-party software do not adjust the volume of the television according to the above procedure, but set the initial volume by itself, or use the current volume of the mobile terminal as the initial volume, and adjust the volume of the television on the basis of the two initial volumes. This volume adjustment may cause the following problems: (1) the volume adjusting direction operated by the user at the mobile terminal is inconsistent with the actual volume adjusting direction of the television terminal. For example, the current volume of the television end is 10, the initial volume of the mobile terminal is 30, the user presses a down key on the mobile terminal, the mobile terminal reduces 10 on the basis of 30 to obtain a target volume 20, the target volume is sent to the television end, the volume of the television end is adjusted from 10 to 20, the actual volume adjustment direction of the television end is finally the volume increase, and the volume adjustment direction of the mobile terminal is the volume decrease; (2) the volume of the television may suddenly become larger or smaller. For example, the current volume of the television terminal is 10, and if 15 is the desired volume of the user, at this time, the initial volume of the mobile terminal is 30, the user wants to press an additional key on the mobile terminal to increase the volume of the television terminal, the mobile terminal adds 10 on the basis of the initial volume 30 to obtain a target volume 40, and sends the target volume to the television terminal, and the volume of the television terminal is adjusted from 10 to 40, which is far beyond the desired volume 15. No matter which kind of problem appears, can lead to can not satisfy user's volume control expectation after the volume adjustment operation, reduce the user to many screen interaction operation's experience degree.

An embodiment of the present invention provides a volume adjusting method, as shown in fig. 2A, including:

s101, receiving a first volume adjusting request from a mobile terminal without actually adjusting the volume of the television terminal, wherein the first volume adjusting request comprises a first target volume;

and certain third-party software of the mobile phone end casts a playing picture to the television end through the DLNA, and then the volume of the television end is adjusted through the mobile phone end. The television end receives a first volume adjustment request from the mobile phone end, wherein the first volume adjustment request comprises a first target volume. And the television end receives the first volume adjustment request, but does not actually adjust the volume of the television end at the moment, and stores the first target volume in the television end so as to perform the next judgment. There are two possible ways to calculate the first target volume obtained at this time: the first is a first target volume obtained by adjusting on the basis of the received television volume according to a standard mode; and secondly, according to a non-standard mode, the mobile phone terminal sends a value set by the mobile phone terminal to the television terminal as a first target volume. For example, the current volume of the television end is 10, a first volume adjustment request is received from the mobile terminal, if the adjustment is performed according to the standard mode, the current volume of the television end is firstly received by 10, and the current volume is increased or decreased on the basis of the current volume of the television end.

S102, receiving a second volume adjustment request from the mobile terminal, wherein the second volume adjustment request comprises a second target volume;

in the last step, after the first target volume is received, only the first target volume is stored, and the volume of the television end is not adjusted according to the first target volume. A second volume adjustment request is received from the mobile terminal, the second volume request including a second target volume.

S103, judging whether the volume of the television end is adjusted according to a standard mode according to the size relation between the first target volume and the second target volume;

and S104, if the first target volume is not equal to the second target volume, judging that the volume of the television end is not adjusted according to a standard mode, and actually adjusting the volume according to a non-standard mode.

If the volume is adjusted according to the non-standard mode, the target volume is not obtained by increasing or decreasing on the basis of the current volume of the television, but the initial volume is set by self or the current volume of the mobile phone terminal is used as the initial volume, and the target volume is obtained by increasing or decreasing on the basis of the two initial volumes. For example, the initial volume of the mobile phone end is 10, when the first target volume is set, an amplitude of 5 is added on the basis of the initial volume of 10 of the mobile phone end to obtain a first target volume 15, and at this time, the volume of the mobile phone end has changed. When the second target volume is set, a magnitude of 5 is added to the changed volume 15 to obtain a second target volume 20.

Therefore, if the first target volume is not equal to the second target volume, it may be determined that the current third-party software adjusts the volume according to the non-standard mode, and the volume of the television terminal should be further adjusted according to the non-standard mode.

Specifically, in combination with the method shown in fig. 2B, the method for actually adjusting the volume in a non-standard manner includes the following steps:

s1041, judging the current volume adjusting direction according to the magnitude relation of the first target volume and the second target volume;

s1042, if the second target volume is larger than the first target volume, judging the current volume adjusting direction as volume increase;

s1043, receiving the current volume of the television terminal, so as to increase the volume on the basis of the current volume of the television terminal.

The user usually sends a volume adjustment command to the television terminal by operating add-drop keys on the mobile terminal, and if the volume is adjusted in a non-standard manner, the volume adjustment of the television terminal cannot be adjusted according to the user's intention (volume adjustment direction). The non-standard way of actually adjusting the volume in steps S401 to S403 can realize that the volume of the television end can be adjusted according to the desire of the user. Specifically, the adjustment intention of the user is judged according to the magnitude relation between the first target volume and the second target volume, that is, whether the operation of the user on the mobile terminal is volume adding or volume reducing.

Continuing to use the above embodiment, the initial volume of the mobile phone end is 10, and an amplitude of 5 is added on the basis of the initial volume of 10 of the mobile phone end to obtain the first target volume 15, where the volume of the mobile phone end has changed. And when the second target volume is obtained, if the operation of the user on the mobile terminal is the volume adding, adding an amplitude 5 on the basis of the first target volume 15 according to the operation of the user to obtain the second target volume 20. By comparing the first target volume 15 with the second target volume 20, it can be obtained that the user operates on the mobile terminal to add volume, that is, the user's will of volume adjustment is to increase volume, that is, the current volume adjustment direction is to increase volume. And finally, increasing the volume on the basis of the received current volume of the television end, wherein the volume adjustment result of the television end corresponds to the operation of the user on the mobile terminal. Therefore, after the user performs volume adjustment operation, the volume adjustment meets the volume adjustment expectation of the user, and the experience degree of multi-screen interaction operation of the user is improved.

Here, if the second target volume is less than the first target volume, it is determined that the current volume adjustment direction is a reduced volume; and receiving the current volume of the television end so as to reduce the volume on the basis of the current volume of the television end. For example, the initial volume of the mobile phone end is 10, and a magnitude of 5 is added on the basis of the initial volume of 10 of the mobile phone end to obtain a first target volume 15, where the volume of the mobile phone end is changed at this time. And when the second target volume is obtained, if the operation of the user on the mobile terminal is volume reduction, reducing by 5 on the basis of the first target volume 15 according to the operation of the user to obtain a second target volume 10. By comparing the first target volume 15 with the second target volume 10, it can be obtained that the user operates on the mobile terminal to reduce the volume, that is, the user's will of volume adjustment is to reduce the volume, that is, the current volume adjustment direction is to reduce the volume. And finally, reducing the volume on the basis of the current volume of the received television end, wherein the volume adjustment result of the television end is also corresponding to the operation of the user on the mobile terminal.

In some embodiments, if the first target volume is equal to the second target volume, it is determined that the volume of the television terminal is adjusted according to a standard manner, and actually adjusting the volume according to the standard manner, specifically including: receiving the current volume of the television end; and if the second target volume is larger than the current volume of the television end, increasing the volume on the basis of the current volume of the television end.

Specifically, if the volume is actually adjusted according to the standard mode, the target volume is obtained by adding or subtracting the current volume of the television. When the volume is actually adjusted in a standard manner, the first target volume is to increase the volume on the basis of the volume of the television terminal after receiving the volume of the television terminal. The second target volume is also after receiving the volume of the television end, and then the volume is increased on the basis of the volume of the television end. For example, the current volume of the television is 10, and the first target volume is calculated by adding an amplitude to the current volume of the television 10 to obtain a value of 15. However, since the tv volume is not actually adjusted after the first target volume is obtained, the second target volume is still calculated by adding an amplitude to the current volume 10 of the receiving tv end, and the value of the second target volume is also 15.

Therefore, if the first target volume is equal to the second target volume, the current volume adjusting mode of the television can be judged to be the standard mode. And actually adjusting the volume of the television end according to a standard mode, wherein the second target volume is obtained by calculating the current volume of the television end, so that the adjustment can be directly performed according to the second target volume and the current volume of the television end. If the second target volume is larger than the current volume of the television, the volume of the television is increased; if the second target volume is smaller than the current volume of the television, the volume of the television is reduced; and if the second target volume is equal to the current volume of the television, keeping the current volume of the television.

In the above embodiment, when receiving the first volume adjustment request from the mobile terminal, the volume of the television terminal is not actually adjusted, where the first volume adjustment request includes a first target volume, the second volume adjustment request includes a second target volume, and by comparing a magnitude relationship between the first target volume and the second target volume, it is determined whether third-party software of the mobile terminal adjusts the volume of the television terminal according to the standard mode or according to the non-standard mode, and if the first target volume is not equal to the second target volume, it is determined that the volume of the television terminal is adjusted according to the non-standard mode. And then, continuing to adjust the volume according to the non-standard mode, judging the current required volume adjustment direction of the television terminal by comparing the magnitude relation of the first target volume and the second target volume, and then adjusting the volume according to the determined volume adjustment direction. Therefore, after the user performs volume adjustment operation, the volume adjustment meets the volume adjustment expectation of the user, and the experience degree of multi-screen interaction operation of the user is improved.

Further, in combination with the method shown in fig. 2C, the volume adjusting method of the present application further includes the following steps:

s201, receiving a third volume adjusting request from the mobile terminal, wherein the third volume adjusting request comprises a third target volume;

s202, judging the current volume adjusting direction according to the magnitude relation between the third target volume and the second target volume;

s203, if the third target volume and the second target volume are equal to the highest volume, judging that the current volume adjusting direction is volume increase;

and S204, receiving the current volume of the television end so as to increase the volume on the basis of the current volume of the television end.

The third party application is judged to be in the non-standard adjusting mode to adjust the volume according to the steps from the step S101 to the step S104, and the user can adjust the volume according to the judgment result of the previous volume adjusting mode in the next volume adjusting process. For example, continuing to receive a third volume adjustment request from the mobile terminal, the third volume adjustment request includes a third target volume. And judging the current volume adjusting direction according to the magnitude relation between the three target volumes and the second target volume, namely judging whether the intention of the user for adjusting the volume at this time is to increase the volume or reduce the volume. If the third target volume is greater than the second target volume, it may be determined that the user's intention to adjust the volume this time is to increase the volume, i.e., the current volume adjustment direction is to increase the volume. If the third target volume is smaller than the second target volume, it can be determined that the intention of the user to adjust the volume this time is to decrease the volume, that is, the current volume adjustment direction is to decrease the volume. And if the third target volume is equal to the second target volume and is greater than the lowest volume and less than the maximum volume, for example, greater than the lowest volume 0 and less than the maximum volume 100, maintaining the current volume of the television.

In some embodiments, if the third target volume and the second target volume are both equal to the highest volume, for example, both equal to the highest volume 100, it may be determined that the user has been pressed, that is, the current volume adjustment direction is increasing volume. And receiving the current volume of the television terminal, and increasing the volume on the basis of the current volume of the television terminal. If the third target volume and the second target volume are both equal to the lowest volume, for example, both equal to the lowest volume, it may be determined that the user is constantly pressed down, that is, it is determined that the current volume adjustment direction is decreasing volume. And receiving the current volume of the television terminal, and reducing the volume on the basis of the current volume of the television terminal.

Here, it may also be configured that the amplitude of volume adjustment is unified to be P, and if the second target volume is greater than the current volume of the television, then increasing the volume on the basis of the current volume of the television specifically includes: and if the second target volume is larger than the current volume of the television end, increasing an adjusting amplitude on the basis of the current volume of the television end. Or, if the third target volume is greater than the second target volume, it may be determined that the user's intention to adjust the volume this time is to increase the volume, that is, the current volume adjustment direction is to increase the volume, and an adjustment range is increased on the basis of the current volume of the television.

For example, setting the adjustment range to 5, setting the current volume of the television to 30, and if the third target volume is greater than the second target volume, then the current volume adjustment direction is to increase the volume, then increasing an adjustment range P on the basis of the current volume of the television 30, and obtaining a resulting volume 35. And finally, adjusting the volume of the television end to 35 according to the result volume 35. Therefore, after all the third-party software is connected with the television end, when the volume of the television end is adjusted through the mobile terminal, the volume is adjusted according to the self adjusting amplitude of the television end, and the situation that the adjusting amplitudes of different third-party software are inconsistent and the adjusting result is not in line with the user requirement is prevented.

In addition, in the calculation process of the result volume, the obtained calculation result may be smaller than the lowest volume of the television end or larger than the maximum volume of the television end. After receiving the result volume, the volume of the television end can be adjusted according to the relation between the result volume and the minimum volume and the maximum volume. For example, after the calculation, if the resulting volume is less than the lowest volume 0, the volume of the television end is adjusted to the lowest volume 0. And if the volume is larger than the maximum volume 100, adjusting the volume of the television end to the maximum volume 100. And if the resulting volume is larger than the lowest volume 0 and smaller than the maximum volume, adjusting the volume of the television end to the resulting volume.
