Problems solved by technology

[0003] Since the set-top box stores different volume values ​​corresponding to different channels, the volume values ​​of each channel may vary greatly. When switching channels, the volume may suddenly be too large or too low, causing discomfort to the viewer. Therefore, it is often necessary to pass Remote control to manually adjust the volume

Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0019] In the present invention, the digital TV receiving terminal automatically adjusts the volume of the current channel according to the influence of the current environmental noise value, the volume value of the current channel, time and volume preference on the volume. see figure 1 , is a schematic flow chart of the volume adjustment method for adapting to the environment of the present invention, the process is triggered when channel switching is performed, and the method includes the following steps:

[0020] In step 101, the digital TV receiving terminal determines the estimated volume value F0(E, i) from the influence of the current ambient noise value E and the current channel volume value i on the volume.

[0021] The current environmen...

Abstract

The invention provides an environment self-adaptation volume adjusting method and a digital television reception terminal. The method comprises the following steps: a digital television reception terminal determines a volume estimation value F0 (E, i) according to influences of a present environment noise value E and a present channel volume value i on volume, and obtains a time factor P influencing volume and a volume preference factor q influencing volume; the digital television reception terminal multiplies F0, p and a to obtain a multiply result; a digital television receives the multiplyresult which is taken as a volume value after adjustment. According to the invention, volume adjustment can be carried out with self-adaptation, and number of adjusting volume manually is reduced.

Description

technical field [0001] The invention relates to digital television technology, in particular to an adaptive environment volume adjustment method and a digital television receiving terminal. Background technique [0002] For the existing digital TV technology, during the playback of a certain channel, the user sends a volume adjustment command to the digital TV receiving terminal through the remote control, and the digital TV receiving terminal adjusts the volume of the channel and saves the adjusted volume corresponding to the channel value, the digital TV receiving terminal is, for example, a set-top box; then, when playing the channel next time, the set-top box will use the saved volume value as the volume value when playing the channel currently. [0003] Since the set-top box stores different volume values ​​corresponding to different channels, the volume values ​​of each channel may vary greatly. When switching channels, the volume may suddenly be too large or too low, ...
