Signal source generation system and control method thereof

Abstract

The invention discloses a signal source generation system and a control method thereof. The signal source generation system comprises a remote control device and a master control device; the master control device comprises a first control module, a first power supply module, a first infrared module and an audio and video module; the audio and video module is composed of a digital audio module, an AV module, an aberration module, an S terminal module and a second HDMI module; the remote control device is composed of a second control module, a second power supply module, a button module and a second infrared module; and the second power supply module supplies power to the second control module, the second control module processes button data of the button module, and the button data is sent via the second infrared module. The signal source generation system and the control method thereof have the advantages that abundant input or output signals are provided, the integrated degree is high, requirements of different application occasions can be met, each path of signals can be controlled via software, and use is flexible.

Description

technical field [0001] The invention relates to the technical field of audio and video testing, in particular to a signal source generating system and a control method thereof. Background technique [0002] The current audio and video equipment (such as TV) has rich interface resources, such as VGA, HDMI, Audio, LAN, USB and other interfaces, and the corresponding signal source is required as the input to test such equipment, but the current signal source equipment Relatively simple, such as CD, DVD can provide audio and video interfaces, but no VGA, LAN, USB and other interfaces, ordinary computers have VGA, LAN, USB and other interfaces, but no SPDIF, AV and other interfaces, if you need to use multiple signals When using multiple sources, multiple devices (such as DVD+computers) are needed, which wastes resources and is difficult to install and debug, and it is impossible to realize intelligent control of the signals of each signal source. [0003] In the prior art, when...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that in the prior art, when there are many types of interfaces to be tested on audio and video equipment, multiple signal source devices are required to cooperate with the test, which wastes resources, increases the complexity of installation and debugging, and is difficult for The signal of each signal source cannot realize the defect of intelligent control, and a signal source generation system and its control method are provided
