Embodiment 1

[0018] Such as figure 1 As shown, the three-way HDMI signal source switching device includes an infrared remote controller and a signal processor, and the signal processor is provided with three HDMI signal input ports and one HDMI signal output port, and the three HDMI signal input ports are respectively HDMI1 Input port, HDMI2 input port and HDMI3 input port, and the signal processor is also connected with a power module and an infrared receiving module respectively. When implementing it: connect the 5V power adapter to the 220V general circuit, and then connect its plug to the power module The 5V DC power interface provides working power for the device; three HDMI signal sources are input to the signal processor through three HDMI signal input ports; the control command is sent to the infrared receiving module through the infrared remote control, and the infrared receiving module receives the control command After receiving the control command, the signal processor selects ...

Embodiment 2

[0020] As an optimization to the above-mentioned embodiment, a red LED indicator light is set on the infrared receiving module. Successfully received the control command, if the red LED indicator flashes once, it means that the infrared receiving module has successfully received the control command.

Embodiment 3

[0022] As an optimization of the above-mentioned embodiment, three selection buttons are connected to the signal processor, respectively labeled as 1, 2, and 3 to correspond to the HDMI1 input port, HDMI2 input port, and HDMI3 input port. When unavailable, the HDMI source can be switched with three selection buttons.

Abstract

The invention discloses three-way HDMI signal source switching equipment. The equipment comprises an infrared remote control and a signal processor; the signal processor is provided with three HDMI signal input ports and one HDMI signal output port, and the signal processor is further respectively connected with a power module and an infrared receiving module; when in use, the power module provides a 5V direct current working power supply to the signal processor; three HDMI signal input ports input three-way HDMI signal sources to the signal processor; the infrared receiving module receives acontrol command sent out by the infrared remote control, and transmits the control command to the signal processor; and the signal processor selects the inputted three-way HDMI signal sources after receiving the control command, processes the selected HDMI signal sources, and outputs the processed HDMI signals through the HDMI signal output port. The equipment has two sets of control ends, and played HDMI signal sources can be switched at any time during use, thus the operation is convenient and efficient.

Description

technical field [0001] The invention relates to an HDMI signal processing device, in particular to a three-way HDMI signal source switching device. Background technique [0002] In daily work meetings, it is sometimes necessary to display and play multiple HDMI signal sources, but existing HDMI display devices can only play a single HDMI signal source through an HDMI cable, and cannot switch between different HDMI signal sources. . Contents of the invention [0003] The present invention aims at the problem that the prior art cannot switch and play different HDMI signal sources, and provides a three-way HDMI signal source switching device, which can be connected to three HDMI signal sources at the same time during application, and then through infrared remote control The device selects one HDMI signal source for playback, and the HDMI signal source can be switched at any time during the playback process. [0004] The present invention is realized through the following te...
