Embodiment Construction

[0052] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0053] see figure 1 , this embodiment provides a video and audio centralized control method, which can be applied in such as figure 2 The video and audio centralized control system 200 (or called audio and video equipment), specifically, can run on the CPU (Central Processing Unit, Central Processing Unit) of the VOD module of the system. The VOD module includes a module with video and audio processing functions, which can be used for audio and video input and output. Since the method runs on the VOD module, this module is an internal video module relative to the method. The control system includes a plurality of external video modules, and the video modules are used to output video information and audio information. In this embodi...

Abstract

The invention discloses an audio and video centralized control method and system. The method comprises the following steps: acquiring an input video switching signal; controlling the switch to switch to the corresponding video module according to the video switching signal and outputting the video information of the video module; acquiring the audio information of the video module, and sending the audio information to the power amplifier module. Through the touch screen, the user can operate on the touch screen in a centralized way, and control all functional units of the audio and video equipment through visualized touching. The audio and video output of all functional units are concentrated in the display or speakers, so the user need not press the keys on individual equipment, improving the overall control experience for the user's audio and video equipment.

Description

technical field [0001] The invention relates to the technical field of audio-visual control, in particular to a method and system for centralized audio-visual control. Background technique [0002] Common audio-visual products include: Blu-ray players, satellite receivers, karaoke machines, karaoke effect devices, power amplifiers, etc. With the improvement of people's living standards, the demand for audio-visual products will become more diverse. If you need to use these function, you need to purchase a variety of equipment products. However, the hardware of different products is different, the functions are independent, the interface standards are not uniform, and the equipment occupies a large space. If the above functions are to be integrated and placed in a set of equipment, there will be problems such as cumbersome wiring of the equipment, inability to switch in real time, inconsistent control methods, and poor operating experience. Contents of the invention [00...
