Description

Audio-visual system and its control method

technical field

The invention relates to an audio-visual system and a control method thereof, in particular to an audio-visual system capable of two-way information exchange with an ambient light source and a control method thereof.

Background technique

Common LCD TVs usually have multiple built-in playback modes, and each playback mode represents a set of multiple preset parameter values, such as a set of preset values such as brightness, contrast, color temperature, sharpness, and sound effects. When watching different programs, the user can directly select a suitable playback mode from the display menu on the TV so as to achieve the best video viewing effect.

In order to increase the overall entertainment effect when users watch videos, US Published Application US 2010/0005062 proposes an audio-visual system that can automatically adjust ambient light sources. This system can control the brightness of lights around the display to simulate different situations.

If it is necessary to replace the lighting source with a different specification due to damage to the surrounding light, the user must re-adjust the parameter values to allow the audio-visual system to operate normally. This not only causes inconvenience in use, but also limits the application of audio-visual systems.
