Embodiment 1

[0022] figure 1 It is a flow chart of a volume control method provided in Embodiment 1 of the present invention. The method is applicable to the situation of controlling the volume, and the method can be executed by a device with a volume control function, and the device can be realized by software and / or hardware. Specifically include the following steps:

[0023] S110. When it is detected that the sound source channel changes from the first sound source channel to the second sound source channel, read the volume parameter corresponding to the second sound source channel, wherein the first sound source channel corresponds to the first volume parameter, and the second sound source channel corresponds to the first sound source channel. The second sound source channel corresponds to the second volume parameter.

[0024] Specifically, in the process of watching or listening to multimedia data, the user will switch the playing multimedia data according to the quality of the mult...

Embodiment 2

[0033] figure 2It is a flow chart of a volume control method provided by Embodiment 2 of the present invention. In this embodiment, on the basis of the above-mentioned embodiments, when it is detected that the sound source channel changes from the first sound source channel to the second sound source channel, before reading the volume parameter corresponding to the second sound source channel, it also includes: Pre-store the volume parameters of each audio source channel in a certain storage space; and optimize the "when the detected audio source channel changes from the first audio source channel to the second audio source channel, read the corresponding volume parameters of the second audio source channel" . Specifically include the following steps:

[0034] S210, pre-store volume parameters of each audio source channel in the set storage space.

[0035] Specifically, a part of the storage space in the system storage space is set, and the set storage space is specially u...

Embodiment 3

[0044] image 3 It is a flow chart of a volume control method provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments, and "when the detected sound source channel changes from the first sound source channel to the second sound source channel, read the volume parameter corresponding to the second sound source channel" is carried out. Optimization, specifically includes the following steps:

[0045] S310. When it is detected that a sound source channel is connected during startup, use the sound source channel connected before the previous shutdown as the first sound source channel, and read the first volume parameter corresponding to the first sound source channel.

[0046] Specifically, each time the system is turned off, the volume parameter setting of the current audio source channel is retained in the system. When the system is turned on next time, it is detected that the system is in a state where a s...

Abstract

The embodiment of the invention discloses a volume control method and a volume control device, wherein the method includes steps of detecting a sound source channel; when the channel is changed from a first sound source channel to a second sound source channel, reading a volume parameter corresponding to the second sound source channel, wherein the first sound source channel is corresponding to a first volume parameter, and the second sound source channel is corresponding to a second volume parameter; loading the second volume parameter to a preset buffer zone; according to the second volume parameter, controlling the sound output device to display the sound source data received from the second sound source channel. The invention realizes the independent control of the sound source data volume in every sound source channel, and solves the problem of big volume change when the sound source channel is switched.

Description

technical field [0001] The present invention relates to the field of multimedia technologies, in particular to a volume control method and device. Background technique [0002] The number of audio and video devices in modern families is gradually increasing, and their use involves the control of their own volume. In some smart home control systems, the existing technology is to gather the controls of all audio and video devices together for centralized control. Multiple audio and video devices share one control device, and the volume control keys on the control device are combined with the volume adjustment keys of each audio and video device to control the corresponding audio and video devices. In the prior art, multiple audio and video devices use the same set of volume parameters. When the system switches between different devices, the output signal amplitudes of different devices are different, resulting in a large volume change when switching devices, and the user exper...
