Embodiment Construction

[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0024] By customizing the DIV interface, the invention cancels the basic useless interface definition of the original specification on the current display products, and redefines the audio transmission channel and the communication channel, so that the display can be connected to the graphics card, and the intelligent device can also be connected directly through the DVI interface. Realize display intelligence. The custom DVI interface adds audio channels and communication channels to achieve a complete connection between monitors and external smart devices.

Abstract

The invention relates to an intelligent display system, an intelligent display and a method for transmitting signals. The intelligent display system comprises a display and an intelligent device which are connected through a digital video interactive (DVI) port. The intelligent device transmits digital video signals to the display through the DVI port, further transmits left sound track voice frequency signals and right sound track voice frequency signals to the display through a first group of two pins in idle pins which are located on the DVI port and are not utilized in transmission of the digital video signals, and is communicated with the display through a second group of two pins in idle pins which are located on the DVI port and are not utilized in transmission of the digital video signals. The system, the display and the method increase a voice frequency transmission channel and a channel for communication between devices by redefining the original DVI port under the condition that the newly added channels are compatible with the original digital video signal transmission channel. Only one DVI connection wire is needed to transmit digital video signals, voice frequency signals and communication signals simultaneously, using cost of display products is reduced, and the display can be more conveniently connected with the intelligent device.

Description

technical field [0001] The present invention relates to display technology, and more particularly, to an intelligent display system, an intelligent display and a method for transmitting signals. Background technique [0002] DVI (Digital Visual Interface), that is, digital video interface, is an interface standard launched in 1999 by Silicon Image, Intel, Compaq, IBM, HP, NEC, Fujitsu and other companies to form DDWG (Digital Display Working Group, Digital Display Working Group). . At present, the DVI interface has been widely used in the connection between the monitor and the graphics card to transmit digital video signals. The commonly used DVI interface definition is as follows: [0003] pin Definition pin Definition 1 TMDS data 2- 13 TMDS Data 3+ 2 TMDS Data 2+ 14 +5V DC power supply 3 TMDS Data 2 / 4 Shield 15 ground 4 TMDS data 4- 16 Hot plug detection ...
