Embodiment Construction

[0052] The following is attached Figure 1-4 The application is described in further detail.

[0053] The embodiment of the present application discloses a two-way universal video switching device.

[0054] refer to figure 1 The two-way universal video adapter device includes an adapter cable, one end of the adapter cable is fixed with a TypeC male connector 1 for connecting to a TypeC interface, and the other end is fixed with a DP male connector 2 for connecting with a DP interface.

[0055] A controller 3 , a first signal switch module 41 and a second signal switch module 42 are arranged on the adapter cable. The controller 3 is a TYPEC-CC controller 3 , and the first signal switch module 41 and the second signal switch module 42 are both signal switch chips. The TYPEC-CC controller 3 judges the current Source terminal (the Source terminal is the output terminal of the data source), and turns on or off the first signal switch module 41 or the second signal switch module ...

Abstract

The invention relates to a bidirectional universal video switching device, and the device comprises a switching line, wherein one end of the switching line is provided with a TypeC male head, and the other end of the switching line is provided with a DP male head. A controller, a first signal change-over switch module and a second signal change-over switch module are arranged on the patch cord, and the controller judges the current Source end and turns on or turns off the first signal change-over switch module or the second signal change-over switch module according to the judgment result. After the patch cord is connected to a PC and a display, the controller judges the current Source end, and if the TypeC male head is the Source end, the controller starts the first signal change-over switch module, closes the second signal change-over switch module and transmits a DP signal to the DP interface; if the DP male head is a Source end, the controller turns on the second signal change-over switch module and turns off the first signal change-over switch module, and transmits a USB signal to the TypeC interface. Therefore, the patch cord supports a DP and TypeC bidirectional video switching function, and solves the use problem when a user connects a display and a PC host.

Description

technical field [0001] The present application relates to the technical field of video signal switching, in particular to a bidirectional universal video switching device and a control method thereof. Background technique [0002] The Universal Serial Bus Association released a new interface type TypeC for the Universal Serial Bus on August 11, 2014. Its full name is the USB TypeC interface. This interface will be used in future electronic products, such as mobile phones, tablet computers, PC computers and other electronic equipment. [0003] Currently, displays are getting higher resolution and thinner. From 1080p to the current popularization of 2160p, various display brand manufacturers have successively launched 5K and 6K 2880p and 3384p displays. In order to meet the needs of more display content and design users, a high-resolution and ultra-thin and beautiful display design is essential, and the ultra-thin design will give up more interface layouts and positions, and...
