Tx ends first passage HDMI (or DVI) connector 102 and Tx ends second channel HDMI (or DVI) connector 103 obtain After the two-way video card display signal for obtaining host computer, the choosing that alternative is carried out in Tx ends HDMI (or DVI) switch unit 108 is sent to Select, under the control for the switching signal that Tx ends USB extends and control signal transmission unit 105 exports, selected shows letter all the way Number it is sent to Tx ends HDMI (or DVI) and extends transmission unit 109 and be converted into after being adapted to extend the signal format of transmission, passes through extension Transmission line 3 is transferred to up to receiver 2.

In receiver 2, Rx ends HDMI (or DVI) extends transmission unit 209 and the signal for extending transmission is reverted into standard HDMI (or DVI) show signal after, be sent to Rx ends HDMI (or DVI) switch unit 210 carry out channel selecting, passage is by computer User's mode of operation switch 205 sends signal and selected, and the signal of status switch 205 is sent to Rx ends control signal processor 208, under the control of Rx ends control signal processor 208, the display signal of selected passage switches list through Rx ends HDMI (or DVI) Member 210 is sent to the VR glasses being connected with Rx ends first passage HDMI (or DVI) connector 203, or with Rx ends second channel The computer monitor that HDMI (or DVI) connector 202 connects, complete HDMI (or DVI) signal extending channel is formed, realizing will The two-way of host computer shows that signal extends and is transferred to 50~100 meters of VR glasses and the functional requirement of computer monitor.

Computer user can be switched using VR glasses or computer monitor, tool using the status switch 205 on receiver 2 Body running step is：

1. when 205 selection VR glasses of computer user down state switch, status switch 205 forms a switching signal hair Rx ends control signal processor 208 is given, this switching signal is converted into controlling electric signal by Rx ends control signal processor 208 Notice Rx end HDMI (or DVI) switch unit 210 switches over operation, will input into Rx ends HDMI (or DVI) switch unit 210 Display signal switching be output on Rx ends first passage HDMI (or DVI) connector 203, be finally output to VR glasses.Now, No signal exports on Rx ends second channel HDMI (or DVI) connector 202.Meanwhile Rx ends control signal processor 208 is by state After switch 205 selects the switching signal of VR glasses to be encoded into the form for being adapted to extension to transmit, it is sent to Rx ends USB and extends and control letter Number transmission unit 206, Tx ends USB is sent to by extending transmission line 3 and is extended and control signal transmission unit 105, is reduced into switch After signal, Tx end HDMI (or DVI) switch unit 108 is controlled, Tx ends first passage HDMI (or DVI) connector 102 is inputted The display signal of computer display card first passage be output to Tx ends HDMI (or DVI) from Tx ends HDMI (or DVI) switch unit 108 Extend transmission unit 109.Now, it is logical by the computer display card second inputted on Tx ends second channel HDMI (or DVI) connector 103 Road shows that signal is dropped.

2. when 205 selection computer monitor of computer user down state switch, status switch 205 forms another switch Signal is sent to Rx ends control signal processor 208, and this another switching signal is converted into by Rx ends control signal processor 208 Control signal notice Rx end HDMI (or DVI) switch unit 210 switches over operation, will input and is cut into Rx ends HDMI (or DVI) The display signal switching for changing unit 210 is output on Rx ends second channel HDMI (or DVI) connector 202, is finally output to electricity Brain display.Now, no signal exports on Rx ends first passage HDMI (or DVI) connector 203.Meanwhile Rx ends control signal After status switch 205 is selected the switching signal of computer monitor to be encoded into the form for being adapted to extension to transmit by processor 208, it is sent to Rx ends USB extends and control signal transmission unit 206, and by extending, transmission line 3 is sent to Tx ends USB extensions and control signal is transmitted Unit 105, after being reduced into switching signal, control Tx end HDMI (or DVI) switch unit 108, by Tx ends second channel HDMI (or DVI) the display signal for the computer display card second channel that connector 103 inputs exports from Tx ends HDMI (or DVI) switch unit 108 Extend transmission unit 109 to Tx ends HDMI (or DVI), now, by what is inputted on first passage HDMI (or DVI) connector 102 Computer display card first passage shows that signal is dropped.

During in order to ensure that computer user switches between VR glasses and computer monitor, host computer will not mistake sentence Disconnected display device (VR glasses or computer monitor) has carried out Plug Action so that computer system is driven loading/unloading load automatically Action and cause the compatibility issue of various systems, in the utility model, first passage EDID/ is provided with transmitter 1 HPD latch 106 and second channel EDID/HPD latch 107.

In use, first passage EDID/HPD latch 106 user's use state switch 205 selection VR glasses when, Whether detection VR glasses normally connect, can be by the HPD states and EDID parameters of VR glasses after confirming that VR glasses normally connect First passage EDID/HPD latch 106 is stored in, for the EDID and HPD of computer display card real-time query VR glasses.

Second channel EDID/HPD latch 107 is in 205 selection computer monitor of user's use state switch, detection electricity Whether brain display normally connects, once confirming computer monitor normally after connection, can by the HPD states of computer monitor and EDID parameters are stored in 2 passage EDID/HPD latch 107, for the EDID and HPD of computer display card real-time query traditional monitor.

The utility model host computer is focused on using host computer extension fixture computer room centralized management in the case of, VR glasses and computer monitor are connected simultaneously on the receiver of host computer extender, and can be in VR glasses and computer monitor Between switch display, solve prior art and can not extend transmitting two paths image resolution ratio and be more than or equal to 2560X1440@60Hz superelevation The problem of clear computer picture signals.

Status switch 205 can be physical switch, the outside connected switch accessed by lead, by being patrolled caused by USB passages Switching signal is collected, logical switching signal can derive from system and the games system order of host computer, or the control of VR glasses Control signal caused by handle.

In the present embodiment, Tx ends USB extends and control signal transmission unit 105 is had using Tianjin Rui Fake semiconductor technologies The NS1021 types USB of limit company extends and control signal transmission unit, and Tx ends HDMI (or DVI) extends transmission unit 109 and used The NS5530 types of Tianjin Rui Fake semiconductor technologies Co., Ltd extend transmission unit, Tx ends HDMI (or DVI) switch unit 108 Using the PI3HDMI336 switch units of PTI PERICOM semiconductor companies of the U.S., first passage extending display identification data EDID/ hot plugs detection HPD latch 106 likes the 24C02 types latch and platform of special Mel ATMEL semiconductor companies using the U.S. Simulators (or EDID simulator) of the EDID of Wan Ruichuan companies with standard scheme, second channel EDID/HPD latch 107 are adopted With the 24C02 types latch of the special Mel ATMEL semiconductor companies of love of the U.S. and the EDID of Taiwan Rui Chuan companies with standard scheme Simulator (or EDID simulators), Rx ends USB extends and control signal transmission unit 206 uses Tianjin Rui Fake semiconductor technologies The NS1021 of Co., Ltd extends and control signal transmission unit, and Rx ends HDMI (or DVI) extends transmission unit 209 and uses Tianjin The NS5531 of Rui Fake semiconductor technologies Co., Ltd extends transmission unit, and Rx ends HDMI (or DVI) switch unit 210 is using beautiful The PI3HDMI412 type switch units of PTI PERICOM semiconductor companies of state, Rx ends control signal processor 208 use one The schmidt door circuit 74HC14 of standard, physical switch action is processed into the transistor-transistor logic circuit TTL's of standard Logic level 1 and 0, it is possible to extend to extend and control with control signal transmission unit 105 and Rx ends USB by Tx ends USB and believe Number transmission unit 206 transmits, you can be extended using the NS1021 of Tianjin Rui Fake semiconductor technologies Co., Ltd and control is believed Number transmission unit transmission universal input/output GPIO states.
