First, the analog EDID unit 102 in the transmitter module 100TX generates an analog EDID signal 102a in the transmitter module 100TX according to the parameters of the image source 20. Specifically, the analog EDID unit 102 simulates and calculates an analog EDID signal 102a in the transmitting module 100TX according to the number of the image source terminals 20, the actual parameters of the video card, and other parameters, which is larger than the EDID (external Display Identification Data) of each image source terminal 20, and then the image source terminal 20 receives and acquires the analog EDID signal 102a calculated by the transmitting module 100TX, so as to facilitate the subsequent operation.
After the video source terminal 20 receives the analog EDID signal 102a, the video source terminal 20 generates a physical frame 20a according to the analog EDID signal 102a and stores the physical frame in the memory unit 103 of the transmitting module 100 TX.
While generating the physical screen 20a, the visibility range unit 104 in the receiving module 100RX obtains and stores a visibility range parameter 104a from the image output terminal 30. In another embodiment, the receiving module 100RX is further coupled to a peripheral device 40 capable of inputting commands, such as a keyboard, a mouse, etc., and a user or an administrator inputs the visibility range parameter 104a through the peripheral device 40. It should be noted that the visibility range parameter 104a obtained by the visibility range unit 104 is not necessarily transmitted to the host of the image source 20, but is directly transmitted to the logic circuit unit 106, and the visibility range parameter 104a input by the peripheral device 40 is transmitted to the host of the image source 20, as shown by the dotted line in fig. 1.
In an embodiment, after the transmitting module 100TX finishes obtaining the physical frame 20a of the image source 20 and finishes obtaining the visible range parameter 104a of the image output 30, the logic circuit unit 106 of the transmitting module 100TX captures at least a portion of the physical frame 20a according to the visible range parameter 104a to form a visible range frame 106a, and transmits the visible range frame 106a to the image output 30. In one embodiment, the logic unit 106 comprises a Field Programmable Gate Array (FPGA). It should be understood by those skilled in the art that, in principle, the size of the physical frame 20a is larger than that of the visual range frame 106a, i.e., the physical frame 20a provides at least two visual range frames 106a for the image output terminal 30. In this way, the transmission module 100TX transmits the completed visible range frame 106a to the receiving module 100RX through the cable, and then transmits the frame to the image output unit 30, so as to achieve signal extension without being limited by the interface bandwidth.
FIG. 3 is a schematic diagram showing the signal extender and distributor of the present invention, which transmits each of a plurality of visual range frames 106a to different video output terminals 30, thereby achieving the signal extension and signal synchronization functions. In this embodiment, the application of fig. 2 is used as a derivative, a distributor 50 is coupled between the transmitting module 100TX and the image source 20, the principle of fig. 3 simulates fig. 2, and the structure of the internal units of the transmitting module 100TX and the receiving module 100RX in fig. 3 is omitted for simplicity and clarity.
Referring to fig. 3, after the analog EDID unit 102 of each transmitting module 100TX receives the analog EDID signal 102a, the video source 20 generates a physical frame 20a according to the analog EDID signal 102a through the distributor 50, and stores the physical frame in the memory unit 103 of each transmitting module 100 TX; the visibility range unit 104 in each receiving module 100RX obtains and stores the visibility range parameter 104a to the image output terminal 30. After the transmitting module 100TX finishes obtaining the physical frame 20a of the image source 20 and finishes obtaining the visible range parameter 104a of each image output 30, the logic circuit unit 106 of each transmitting module 100TX captures at least a portion of the physical frame 20a according to the different visible range parameters 104a to form at least two visible range frames 106a, and transmits the visible range frames to the corresponding image output 30.
Referring to fig. 4, a flowchart illustrating steps for implementing the devices 100, 100TX and 100RX according to an embodiment of the present invention is shown. The flow described herein provides examples of the different steps. Although a particular order and sequence is disclosed, the order of the steps of the flowchart may be altered unless otherwise specified. Thus, the flow is exemplary only, and flows may be performed by different sequential steps, even though some steps may be in parallel at the same time. In addition, not every execution includes the same steps, so one or more of the steps may be omitted from the embodiments described herein. The invention also includes other steps.

Step 304: a physical frame 20a is generated. The video source 20 obtains the analog EDID signal 102a to generate a real frame 20 a. After the video source 20 receives the analog EDID signal 102a, the video source 20 generates a physical frame 20a according to the analog EDID signal 102a and stores the physical frame in the apparatus 100.
In one embodiment, step 302 and step 304 are performed concurrently, without any order.
Step 306: a visible range parameter 104a of the image output terminal 30 is obtained. While generating the physical screen 20a, the visual range unit 104 in the apparatus 100 obtains and stores a visual range parameter 104a from the image output terminal 30. In another embodiment, the apparatus 100 is further coupled to a peripheral device 40 capable of inputting commands, such as a keyboard, a mouse, etc., and a user or an administrator inputs the visibility range parameter 104a through the peripheral device 40.
In one embodiment, step 306 may be performed concurrently with step 302 and step 304, or may be performed independently.

In one embodiment, the logic circuit unit 106 is coupled between the analog EDID unit 102 and the visible range unit 104. After the apparatus 100 finishes obtaining the physical frame 20a of the image source 20 and finishes obtaining the visible range parameter 104a of the image output 30, the logic circuit unit 106 extracts the visible range frame 106a from the physical frame 20a according to the visible range parameter 104a, and transmits the visible range frame to the image output 30. In one embodiment, the logic unit 106 comprises a Field Programmable Gate Array (FPGA).
In one embodiment, the apparatus 100 further includes a switching unit 108 and a memory unit 103. The memory unit 103 is used for storing the physical frame 20a, the visible range parameter 104a and the visible range frame 106 a.

In one embodiment, the Channel 2082 may be a Display Data Channel (DDC).
Step 310: the visible range frame 106a is transmitted to the image output terminal 30. In analogy to fig. 1-3, at least two frames 106 of the visual range generated by the device 100 can be transmitted to the corresponding virtual display device (i.e., the image output 30) through wireless communication or wired communication.
The interface of the apparatus 100 described herein includes a physical port and a transmission interface thereof, which must match with the interface of the video source 20 and the video output 30, for example, if the video source 20 adopts an HDMI interface transmitter, the interface of the apparatus 100 should adopt an HDMI interface, and the physical port should adopt an HDMI dedicated connector.
