Drawings
FIG. 1 is a schematic diagram of an KVM control device according to the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be further described below with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present invention provides an KVM controller for an extended output computer, including the following:
the system comprises a computer display card 1, an encoder 2, a switch 3, a decoder 4, a display 5 and a keyboard and a mouse 6; the encoder 2 comprises an HDMI interface and a USB interface and is connected with the computer display card 1 through an HDMI line; the encoder 2 is also connected with the switch 3 through a network cable; the decoder 4 comprises an HDMI interface and a USB interface; the display 5 is connected with the decoder 4 through an HDMI line; the keyboard and mouse 6 is connected with the decoder 4 through a USB interface.
The computer display card 1 is provided with a plurality of HDMI interfaces, and each HDMI output signal is an associated splicing signal.
The encoder 2 has a plurality of HDMI interfaces corresponding to the HDMI interfaces of the computer graphics card 1 one to one.
The decoder 4 is also provided with a plurality of HDMI interfaces, and correspondingly, a plurality of displays 5 are provided; each HDMI interface of the decoder 4 is correspondingly connected with one display 5.
The keyboard and mouse 6 only has 1 set and can freely move in each display connected with the decoder 4, and the generated control signal is fed back to the display of the computer terminal in real time.
The type of the encoder 2 is XT 2402B-FH-K.
The decoder 4 model is XT6402B-FH-K.
The embodiment of the utility model provides an in, computer display card provides two HDMI interfaces, nevertheless can provide the HDMI interface more than 2 at least ways according to different practical scene demands to realize multichannel audio video signal and decode in step after accomplishing the network teletransmission, realize keyboard mouse control in expanding the screen simultaneously.
Two paths of video extension signals of the same display card are input into an encoder (a two-path distributed input node box), compression encoding is carried out by the ultra-low delay encoding technology through 2 encoding modules respectively, the signals are transmitted to a decoder (a two-path seat control box) through a switch, the signals are decoded and displayed by 2 decoding modules respectively at the end of the control box, the encoding and decoding delay is controlled within 20ms, and therefore the synchronism of the images of the display card output extension screen after remote transmission in a decoding display mode is guaranteed, and the screen is arbitrarily slid through a mouse on 2 decoding display interfaces and operated like a local extension screen computer.
The utility model provides a beneficial effect that technical scheme brought is: after network remote transmission, synchronous decoding of multi-channel audio and video signals is realized, and keyboard and mouse control is realized in the expansion screen.
