Embodiment 1

[0022] Such as figure 1 As shown, LED lights of various colors are arranged on four sides of the room, and audio and video players, such as TVs, etc., have audio and video signal input lines, and the audio and video input lines are connected to the audio and video processing module at the same time.

[0023] The audio processing module is an audio and video signal analysis and processing device, such as a spectrum analysis circuit or an audio decoder, which is used to extract information such as pitch, sound intensity, and timbre in the audio signal in real time, and then convert the pitch, sound intensity, and timbre It is an electrical signal output to the lighting control unit.

[0024] The video signal processing module or video converter is used to extract the R, G, B three primary color component information in the video signal and convert the R, G, B three primary color component information into an electrical signal for output.

[0025] Such as figure 2 As shown, th...

Embodiment 2

[0031] The difference from Example 1 is that, if Figure 4 As shown, the sound signal is amplified by the audio signal amplification module (such as a signal amplifier) ​​and then output, the output electrical signal is used as a voltage signal to control the intensity of the LED light, and the signal output by the light driver module connected to the video signal processing module is used to control the LED light. the switch signal.

Embodiment 3

[0033] The difference from Embodiments 1 and 2 is that the audio signal processing module and the video signal processing module are connected to the wireless receiving module to receive and process audio and video signals from wifi devices. The video playback device synchronously receives and plays the audio and video signals sent by the wifi device. The electrical signal output by the audio signal processing module can also be connected to the speaker light through bluetooth due to control.

Abstract

The invention provides an audio and video signal and light control system, which belongs to the field of multimedia technology. It achieves the effect that the lighting system is dynamically consistent with the audio and video of the TV. The audio and video signal and lighting control system, the audio signal processing module, is connected with the audio line of the audio and video player, and is used to extract the pitch, sound intensity, and timbre information in the audio signal and convert the pitch, sound intensity, and timbre into Electrical signal output; video signal processing module, connected with the video line of the audio and video player, used to extract the R, G, B three primary color component information in the video signal and convert the R, G, B three primary color component information into an electrical signal Output: the light control module is used to receive the electrical signal output by the audio and video signal processing module and control the change of light after processing. The invention realizes the dynamic scene control following the video, which makes people experience the feeling of being on the scene.

Description

technical field [0001] The invention belongs to the field of multimedia technology, and relates to an audio-video control lighting system, in particular to an audio-video signal and lighting control system. As well as light color, color temperature and brightness control methods, audio and video and light change algorithms, etc. Background technique [0002] LED lighting has entered thousands of households. The controllability advantages of LED technology in the fields of color and color temperature will promote the further development of light environment from simple switch and brightness control to a new level of fusion switch, brightness, color temperature and color. LED lights are easy to control, easy to adjust the brightness and so on. When people appreciate audio and video, they can only experience the image effect within the screen range, and cannot let people experience the immersive feeling, and cannot experience the atmosphere in the video section well.
