Description

Technical Field

[0001] This invention relates to a video transmission device, and more particularly to a fiber optic matrix. Background Technology

[0002] In hospital operations, surgery has become the hospital's main source of revenue, and in order to improve the quality of surgery, hospitals have invested a considerable amount of money to purchase high-performance operating room instruments and equipment.

[0003] Generally speaking, when doctors perform surgery, they often use auxiliary medical video systems (such as endoscopy systems, surgical navigation systems, angiography systems, da Vinci robots, etc.). In order to achieve better auxiliary effects, the above-mentioned medical video systems mostly need to meet requirements such as high transmission speed, high immediacy, long-distance transmission, low attenuation, good quality, and interoperability.

[0004] However, in the existing technology, the system architecture used to transmit video captured by a video source (such as an endoscope) to a screen that can be viewed by a physician not only has a complex switching relationship, but also easily causes delays in video transmission, thereby increasing the risk of surgery.

[0005] Please refer to Figure 1A This is a known mechanism used for medical video transmission. Figure 1A In this example, it is assumed that the video source 110 is an endoscope that can provide high-definition multimedia interface (HDMI) video, and the display 170 is used to allow the physician to view the video captured by this endoscope. For ease of explanation, it is assumed below that the display 170 can receive video signals through a serial digital interface (SDI) (i.e., the video source 110 and the display 170 correspond to different video standards).

[0006] Generally speaking, in order for the display 170 to successfully display the video captured by the video source 110, an optical transmitter 120, an optical receiver 130, an optical transmitter 150, and an optical receiver 160 need to be sequentially arranged between the video source 110 and the display 170.

[0007] In this case, when the video source 110 obtains video (e.g., endoscopic video) by shooting, the corresponding electrical signal E1 can be provided to the optical transmitter 120, and the optical transmitter 120 can correspondingly convert the electrical signal E1 into an optical signal OP1 and send the optical signal OP1 to the optical receiver 130.

[0008] exist Figure 1AIn this scenario, since the video source 110 is assumed to be used to provide HDMI video, the designer can pre-connect the optical receiver 130 corresponding to the video source 110 to the HDMI input on the electrical matrix 140 when setting up the operating room environment. Therefore, after the optical receiver 130 receives the optical signal OP1, it can convert the optical signal OP1 into an electrical signal E2 and output the electrical signal E2 to the HDMI input on the electrical matrix 140. In other examples, if the video source 110 is used to provide Digital Visual Interface (DVI) video or DisplayPort (DP) video, the designer can change the connection of the optical receiver 130 to the DVI or DP input on the electrical matrix 140.

[0009] In the above example, since the display 170 is assumed to correspond to the SDI standard, its corresponding optical transmitter 150 can be pre-connected by the designer to the SDI-corresponding output terminal on the electrical matrix 140. In this case, when the electrical matrix 140 receives the electrical signal E2, it can convert it into an electrical signal E3 corresponding to the SDI standard and provide the electrical signal E3 to the optical transmitter 150.

[0010] Subsequently, the optical transmitter 150 can convert the electrical signal E3 into the optical signal OP2 and provide the optical signal OP2 to the optical receiver 160. Correspondingly, the optical receiver 160 can convert the optical signal OP2 into the electrical signal E4 and provide the electrical signal E4 to the display 170 so that the display 170 can display the video captured by the video source 110.

[0011] Depend on Figure 1A As can be seen, in the illustrated architecture, a separate optical transmitter / receiver needs to be installed for both the video source 110 and the display 170, thus requiring a total of two sets of optical transmitters / receivers. Furthermore, the signal source connectors differ for different video standards. Therefore, this approach is not only more costly and involves more complex switching relationships, but the multiple optical / electrical signal conversions will also introduce corresponding delays.

[0012] In addition, in order for the electrical matrix 140 to convert the electrical signal E2 corresponding to the HDMI standard into the electrical signal E3 corresponding to the SDI standard, the electrical matrix 140 also needs to perform relatively complex calculations.

[0013] Please refer to Figure 1B It is based on Figure 1A The diagram illustrates the architecture of an electrical matrix. Figure 1BIn this process, when the electrical matrix 140 receives electrical signal E2 from an input port corresponding to the HDMI standard, it must first decode the electrical signal E2 into raw data at the RGB level before the image processor 141 of the electrical matrix 140 can encode this raw data into electrical signal E3 corresponding to the SDI standard. In this case, the conversion operation performed by the electrical matrix 140 will also introduce additional latency. Furthermore, since the electrical matrix 140 costs tens of thousands of US dollars, this makes... Figure 1A The implementation cost of the architecture remains high.

[0014] In addition, measurements were taken. Figure 1A The architecture will result in a delay of approximately 0.3 seconds in the image viewed by the physician on monitor 170. In this scenario, assuming it takes 10 minutes for the video source 110 to travel from the patient's mouth into the stomach, this will result in a total delay of 3.3 minutes in the image viewed by the physician on monitor 170, thereby increasing the surgical risk.

[0015] Therefore, for those skilled in the art, designing a low-complexity, low-latency medical video transmission architecture is an important issue. Summary of the Invention

[0016] In view of this, the present invention provides an optical fiber matrix that can be used to solve the above-mentioned technical problems.

[0017] This invention provides an optical fiber matrix comprising a plurality of input terminals, a plurality of output terminals, and a controller. A first input terminal among the plurality of input terminals receives a first optical signal having a specified transmission rate from a first optical transmitter, wherein the first optical transmitter corresponds to a first video standard. The plurality of output terminals includes a first output terminal. A first correspondence is configured between the first input terminal and the first output terminal, and the controller switches the first input terminal to the first output terminal according to the first correspondence, wherein the first output terminal is used to output the first optical signal from the first input terminal to a first optical receiver, wherein the first optical receiver corresponds to a second video standard.

[0055] Please refer to Figure 2 This is an optical fiber transmission system illustrated according to one embodiment of the present invention. Figure 2 As shown, the fiber optic transmission system 200 includes an optical transmitter 210 and an optical receiver 220, wherein the optical transmitter 210 can be connected between the video source 201 and the optical receiver 220, and the optical receiver 220 can be connected to the display 202.

[0056] In embodiments of the present invention, the video source 201 may correspond to a first video standard, and the display 202 may correspond to a second video standard. In different embodiments, the first video standard may be the same as or different from the second video standard. In some embodiments, the first video standard corresponding to the video source 201 may be, for example, one of the HDMI standard, DVI standard, DP standard, and SDI standard, but is not limited thereto. Similarly, the second video standard corresponding to the display 202 may also be one of the HDMI standard, DVI standard, DP standard, and SDI standard, but is not limited thereto.

[0057] In one embodiment, after the video source 201 (e.g., an endoscope) generates a corresponding video signal ES1 by taking a picture, the video signal ES1 can be transmitted to the optical transmitter 210.

[0058] Accordingly, after receiving the video signal ES1, the optical transmitter 210 can convert the video signal ES1 into an optical signal OS1 with a specified transmission rate and transmit the optical signal OS1 to the optical receiver 220. In some embodiments, the optical transmitter 210 can convert the video signal ES1 into an optical signal OS1 with a specified transmission rate without loss. That is, the optical transmitter 210 can convert the video signal ES1 into an optical signal OS1 with a specified transmission rate without compression, but it is not limited to this.

[0059] In different embodiments, the specified transmission rate may be between 9.984 Gbps and 10.2 Gbps. In a preferred embodiment, the specified transmission rate may be 10 Gbps, but is not limited thereto.

[0060] After the optical receiver 220 receives the optical signal OS1 with the specified transmission rate from the optical transmitter 210, the optical receiver 220 can convert the optical signal OS1 into a video signal ES2 corresponding to the second video standard, and output the video signal ES2 to the display 202 corresponding to the second video standard. In this way, the display 202 can display the image captured by the video source 201.

[0061] Furthermore, since the optical transmitter 210 is designed to convert the video signal ES1 corresponding to the first video standard into an optical signal OS1 with a specified transmission rate, and the optical receiver 220 is also designed to convert the optical signal OS1 with a specified transmission rate into a video signal ES2 corresponding to the second video standard, even if the video source 201 and the display 202 correspond to different video standards, the optical signal OS1 provided by the optical transmitter 210 can be directly transmitted to the optical receiver 220 without any conversion.

[0062] As can be seen from the above, compared to Figure 1A The system requires an electrical matrix and two sets of optical transmitters / receivers. Figure 2 With only one set of optical transmitters 210 and optical receivers 220 placed between the video source 201 and the display 202, communication with... Figure 1A It features the same architecture for video transmission functionality. Furthermore, Figure 2 In addition to its lower complexity, the architecture's switching relationships also achieve lower latency by reducing the number of optical / electrical signal conversions.

[0063] After measurement, Figure 2 The latency introduced by the architecture is approximately 2μs, which is only Figure 1A One in 150,000 of the architecture. Furthermore, without needing to install electrical matrix switches costing tens of thousands of dollars. Figure 2 The implementation cost is also much lower Figure 1A Architecture.

[0064] Please refer to Figure 3A This is a schematic diagram of an optical transmitter and optical receiver architecture according to one embodiment of the present invention. Figure 3A In this scenario, it is assumed that the first video standard corresponding to the video source 201 is either the HDMI standard or the DVI standard, and it is assumed that the second video standard corresponding to the display 202 is either the HDMI standard or the DVI standard. In this case, the video signal ES1 provided by the video source 201 is, for example, a Transition Minimized Differential Signaling (TMDS) signal (hereinafter referred to as the first TMDS signal).

[0065] like Figure 3A As shown, the optical transmitter 210 includes a first TMDS transceiver 311, a serializer 312, an optical transceiver 313, and a controller 314. In some embodiments, the first TMDS transceiver 311 can receive and remove noise from a first TMDS signal (i.e., video signal ES1) from a video source 201. Then, the serializer 312, coupled to the first TMDS transceiver 311, can receive the cleaned first TMDS signal ES1' and serialize it into a first serial signal TS1. In some embodiments, the serializer 312 can be configured to output only serial signals with the specified transmission rate. In this case, regardless of the video signal ES1 corresponding to a video signal of what quality, the serializer 312 will correspondingly generate a serial signal with the specified transmission rate, but this is not limited to this. Next, the optical transceiver 313 coupled to the serializer 312 can convert the first serial signal TS1 into an optical signal OS1 with a specified transmission rate. Figure 3A In this process, the optical transmitter 210 can transmit the optical signal OS1 to the optical receiver 220 through the optical fiber 330 connected between the optical transmitter 210 and the optical receiver 220.

[0066] In different embodiments, the operations performed by the first TMDS transceiver 311, serializer 312, and optical transceiver 313 can all be controlled by the controller 314 coupled to the first TMDS transceiver 311, serializer 312, and optical transceiver 313 through corresponding control signals, but this is not a limitation. In some embodiments, the controller 314 can enable the optical transceiver 313 after the first TMDS transceiver 311 and serializer 312 have completed initialization, thereby preventing the optical transceiver 313 from accidentally sending meaningless data to the optical receiver 220, but this is not a limitation.

[0067] like Figure 3A As shown, the optical receiver 220 may include an optical transceiver 321, a deserializer 322, a second TMDS transceiver 323, and a controller 324. In some embodiments, the optical transceiver 321 may receive an optical signal OS1 from the optical transceiver 313 via an optical fiber 330 and convert the optical signal OS1 into a second serial signal TS2. Then, the deserializer 322, coupled to the optical transceiver 321, may deserialize the second serial signal TS2 from the optical transceiver 321 into a second TMDS signal ES2'. Next, the second TMDS transceiver 323, coupled to the deserializer 322, may receive and remove noise from the second TMDS signal ES2', and output the cleaned second TMDS signal ES2' as a video signal ES2 to the display 202.

[0068] In different embodiments, the operations performed by the optical transceiver 321, deserializer 322, and second TMDS transceiver 323 can all be controlled by the controller 324 coupled to the optical transceiver 321, deserializer 322, and second TMDS transceiver 323 through corresponding control signals, but are not limited to this.

[0069] Please refer to Figure 3B This is a schematic diagram of an optical transmitter and optical receiver architecture according to one embodiment of the present invention. Figure 3B In this scenario, it is assumed that the first video standard corresponding to the video source 201 is the SDI standard or the DP standard, and it is assumed that the second video standard corresponding to the display 202 is the SDI standard or the DP standard.

[0070] like Figure 3B As shown, the optical transmitter 210 includes a first HDMI circuit 315, a serializer 312, an optical transceiver 313, and a controller 314. In some embodiments, the first HDMI circuit 315 receives a video signal ES1 and converts it into a first HDMI signal HS1. Then, the serializer 312, coupled to the first HDMI circuit 315, receives the first HDMI signal HS1 and serializes it into a first serial signal TS1. In some embodiments, the serializer 312 may be configured to output only serial signals with the specified transmission rate. In this case, regardless of the video signal ES1 corresponding to a video signal of what quality, the serializer 312 will correspondingly generate a serial signal with the specified transmission rate, but is not limited to this. Next, the optical transceiver 313, coupled to the serializer 312, converts the first serial signal TS1 into an optical signal OS1 with the specified transmission rate. Figure 3BIn this process, the optical transmitter 210 can transmit the optical signal OS1 to the optical receiver 220 through the optical fiber 330 connected between the optical transmitter 210 and the optical receiver 220.

[0071] In different embodiments, the operations performed by the first HDMI circuit 315, serializer 312, and optical transceiver 313 can all be controlled by the controller 314 coupled to the first HDMI circuit 315, serializer 312, and optical transceiver 313 through corresponding control signals, but this is not a limitation. In some embodiments, the controller 314 can enable the optical transceiver 313 after the first HDMI circuit 315 and serializer 312 have completed initialization, thereby preventing the optical transceiver 313 from accidentally sending meaningless data to the optical receiver 220, but this is not a limitation.

[0072] like Figure 3B As shown, the optical receiver 220 may include an optical transceiver 321, a deserializer 322, a second HDMI circuit 325, and a controller 324. In some embodiments, the optical transceiver 321 may receive an optical signal OS1 from the optical transceiver 313 via an optical fiber 330 and convert the optical signal OS1 into a second serial signal TS2. Then, the deserializer 322, coupled to the optical transceiver 321, may deserialize the second serial signal TS2 from the optical transceiver 321 into a second HDMI signal HS2. Next, the second HDMI circuit 325, coupled to the deserializer 322, may receive the second HDMI signal HS2 and convert it into a video signal ES2 for output to the display 202.

[0073] In different embodiments, the operations performed by the optical transceiver 321, deserializer 322, and second HDMI circuit 325 can all be controlled by the controller 324 coupled to the optical transceiver 321, deserializer 322, and second HDMI circuit 325 through corresponding control signals, but are not limited to this.

[0074] In other embodiments, corresponding to the first video standard corresponding to the video source 201 and the second video standard corresponding to the display 202, Figure 3A The optical transmitter 210 can be arbitrarily connected with... Figure 3A Optical receiver 220 or Figure 3B The optical receiver 220 is paired with it. Similarly, Figure 3B The optical transmitter 210 can also be arbitrarily connected with Figure 3A Optical receiver 220 or Figure 3B It is used in conjunction with the optical receiver 220.

[0075] For example, assuming that video source 201 and display 202 correspond to the HDMI standard and SDI standard respectively, then video source 201 can sequentially transmit through... Figure 3A Optical transmitter 210, optical fiber 330 and Figure 3B The optical receiver 220 is connected to the display 202. For another example, assuming the video source 201 and the display 202 correspond to the SDI standard and the HDMI standard respectively, the video source 201 can sequentially transmit through... Figure 3B Optical transmitter 210, optical fiber 330 and Figure 3A The optical receiver 220 is connected to the display 202. To give another example, assuming the video source 201 and the display 202 correspond to the DP standard and the DVI standard respectively, the video source 201 can sequentially transmit through... Figure 3B Optical transmitter 210, optical fiber 330 and Figure 3A The optical receiver 220 is connected to the display 202.

[0076] Furthermore, in some embodiments, the present invention proposes a fiber optic matrix, which can be used to route optical signals between multiple video sources and displays, thereby enabling more diverse video transmission mechanisms, as detailed below.

[0077] Please refer to Figure 4 This is a schematic diagram of an optical fiber transmission system illustrated according to one embodiment of the present invention. Figure 4 In the optical fiber transmission system 400, there are optical transmitters 210, optical receivers 220 and optical fiber matrix 410. Details of the optical transmitters 210 and optical receivers 220 can be found in the description of the previous embodiments, and will not be repeated here.

[0078] like Figure 4 As shown, the fiber optic matrix 410 may include multiple input terminals I1~I4, multiple output terminals O1~O4, a controller 411, and a communication circuit 412. For ease of explanation, it is assumed below that the optical transmitter 210 is connected to the input terminal I1 and the optical receiver 220 is connected to the output terminal O2, but it is not limited to this.

[0079] In one embodiment, since the display 202 is assumed to be used to display the video captured by the video source 201, a first correspondence can be configured between the input terminal I1 and the output terminal O2 corresponding to the video source 201 and the display 202. In this case, the controller 411 can switch the input terminal I1 to the output terminal O2 according to the first correspondence between the input terminal I1 and the output terminal O2.

[0080] Therefore, after the optical transmitter 210 sends the optical signal OS1 with the specified transmission rate to the input terminal I1, the input terminal I1 can directly forward the optical signal OS1 to the output terminal O2, and the output terminal O2 can correspondingly output the optical signal OS1 to the optical receiver 220.

[0081] In other words, after the fiber optic matrix 410 receives the optical signal OS1 from the optical transmitter 210 through input terminal I1, it can directly output the optical signal OS1 to the optical receiver 220 through the output terminal O2 corresponding to input terminal I1 without performing any processing / conversion on the optical signal OS1. Therefore, compared to Figure 1A Electrical matrix 140, Figure 4 The fiber optic matrix 410 can complete signal transmission with lower latency.

[0082] Furthermore, compared to the price of the electrical matrix 140, which can easily reach tens of thousands of dollars, the fiber optic matrix 410 only costs a few thousand dollars, so its actual cost is much lower than that of the electrical matrix 140.

[0083] In some embodiments, the designer can remotely configure the correspondence between input terminals I1~I4 and output terminals O1~O4 via a network. For example, after determining that input terminal I1 should correspond to output terminal O2, the designer can run control software corresponding to the fiber optic matrix 410 on their operating computer device and edit the first correspondence between input terminal I1 and output terminal O2 in this control software. After completing the configuration of the first correspondence, the computer device can send the corresponding configuration signal CS to the fiber optic matrix 410 via the network.

[0084] Correspondingly, the communication circuit 412 coupled to the controller 411 can receive a configuration signal CS from the network, and the controller 411 can obtain a first correspondence between the input terminal I1 and the output terminal O2 based on the configuration signal CS, and then switch the input terminal I1 to the output terminal O2 according to this first correspondence.

[0085] In other embodiments, the fiber optic matrix 410 may also provide a control panel for the designer to manually set the correspondence between input terminals I1~I4 and output terminals O1~O4. In some embodiments, the control panel may include a plurality of light-emitting diode (LED) buttons corresponding to input terminals I1~I4 and output terminals O1~O4. Therefore, after determining that input terminal I1 must correspond to output terminal O2, the designer can locate the LED button corresponding to input terminal I1 (hereinafter referred to as the first LED button) and the LED button corresponding to output terminal O2 (hereinafter referred to as the second LED button) on the control panel.

[0086] Subsequently, the designer can set the first light-emitting diode button to correspond to the second light-emitting diode button, and the controller 411 can obtain the first correspondence between the input terminal I1 and the output terminal O2, and then switch the input terminal I1 to the output terminal O2 according to the first correspondence, but it is not limited to this.

[0087] In other embodiments, the fiber optic matrix 410 can provide more complex routing capabilities, the details of which are described below.

[0088] Please refer to Figure 5 It is based on Figure 4 A schematic diagram of an optical fiber transmission system. (For example...) Figure 5 As shown, the optical fiber transmission system 500 includes an optical transmitter 210, an optical receiver 220, an optical receiver 220', an optical transmitter 510, an optical receiver 520, and an optical fiber matrix 410.

[0089] exist Figure 5 In addition to the first correspondence between input terminal I1 and output terminal O2, a second correspondence can also be configured between input terminal I1 and output terminal O1. In this case, controller 411 can switch input terminal I1 to output terminal O1 according to this second correspondence. In other words, input terminal I1 can be connected to both output terminals O1 and O2 simultaneously.

[0090] Therefore, after the optical transmitter 210 sends the optical signal OS1 with the specified transmission rate to the input terminal I1, the input terminal I1 can directly forward the optical signal OS1 to the output terminals O1 and O2. Accordingly, the output terminal O1 can output the optical signal OS1 to the optical receiver 220' connected to the output terminal O1, and the output terminal O2 can output the optical signal OS1 to the optical receiver 220' connected to the output terminal O2.

[0091] After receiving the optical signal OS1, the optical receiver 220' can perform operations similar to those of the optical receiver 220 to convert the optical signal OS1 into a video signal ES2' for the display 202' to display the video captured by the video source 201.

[0092] exist Figure 5 In this scenario, the display 202' may correspond to a third video standard, which may be the same as or different from the first and second video standards. For example, assuming the first and second video standards are HDMI and SDI respectively, the third video standard can be any one of HDMI, SDI, DP, and DVI. Accordingly, the optical receiver 220' can be used to convert the optical signal OS1 into a video signal ES2' corresponding to the third video standard for display 202' to present.

[0093] In short, the fiber optic matrix 410 can broadcast the optical signal OS1 from the optical transmitter 210 to the output terminals O1 and O2 based on the first and second correspondences mentioned above, so that the corresponding displays 202 and 202' can display the video image captured by the video source 201, but it is not limited to this.

[0094] Furthermore, assuming that the display 502 can be used to display the video captured by the video source 501, the designer can establish a third correspondence between the input terminal I2 and the output terminal O4 after connecting the corresponding optical transmitter 510 and optical receiver 520 to the selected input terminal (e.g., input terminal I2) and output terminal (e.g., output terminal O4) respectively. In this case, the controller 411 can switch the input terminal I2 to the output terminal O4 according to the third correspondence between the input terminal I2 and the output terminal O4.

[0095] In one embodiment, the video source 501 may correspond to a fourth video standard, while the display 502 may correspond to a fifth video standard. In different embodiments, the fourth video standard may be the same as or different from the fifth video standard. In some embodiments, the fourth video standard corresponding to the video source 501 may be, for example, one of the HDMI standard, DVI standard, DP standard, and SDI standard, but is not limited to these. Similarly, the fifth video standard corresponding to the display 502 may also be one of the HDMI standard, DVI standard, DP standard, and SDI standard, but is not limited to these.

[0096] In one embodiment, after the video source 501 generates a corresponding video signal ES1a by capturing an image, the video signal ES1a can be transmitted to the optical transmitter 510.

[0097] Accordingly, after the optical transmitter 510 receives the video signal ES1a, it can convert the video signal ES1a into an optical signal OS1a with the specified transmission rate, and transmit the optical signal OS1a to the input terminal I2. Then, the input terminal I2 of the fiber optic matrix 410 can directly forward the optical signal OS1a to the output terminal O4, and the output terminal O4 can correspondingly output the optical signal OS1a to the optical receiver 520.

[0098] After the optical receiver 520 receives the optical signal OS1a with the specified transmission rate from the output terminal O4, the optical receiver 520 can convert the optical signal OS1a into a video signal ES2a corresponding to the fifth video standard, and output the video signal ES2a to the display 502 corresponding to the fifth video standard. In this way, the display 502 can display the image captured by the video source 501.

[0099] As can be seen from the above, after the fiber optic matrix 410 receives the optical signal OS1a from the optical transmitter 510 through input terminal I2, it can also directly output the optical signal OS1a to the optical receiver 520 through the output terminal O4 corresponding to input terminal I2 without performing any processing / conversion on the optical signal OS1a. The delay of this process is also much lower than that of the optical receiver 520. Figure 1A Electrical matrix 140.

[0100] In other embodiments, the designer may rely on Figure 5 The concept of instruction allows for the free configuration of other combinations of video sources / displays / optical transmitters / optical receivers, and is not limited to... Figure 5 The state shown is as described.

[0101] In addition, although Figure 4 , Figure 5 The fiber optic matrix 410 is illustrated as having four input terminals I1~I4 and four output terminals O1~O4, but embodiments of the present invention are not limited to this. In other embodiments, those skilled in the art can adjust the fiber optic matrix 410 to have any number of input terminals and output terminals as needed.

[0102] In summary, in the fiber optic transmission system proposed in this invention, the optical transmitter is designed to convert video electrical signals received from a video source into optical signals with a specified transmission rate. Correspondingly, the optical receiver is also designed to convert the optical signals with the specified transmission rate into video electrical signals corresponding to the video standard, so that the display can display the image captured by the video source. Therefore, even if the video source and the display correspond to different video standards, the optical signal provided by the optical transmitter can be directly transmitted to the optical receiver without any conversion. This effectively simplifies the (medical) video transmission process, thereby reducing cost, latency, and complexity.

[0103] Furthermore, by setting up fiber optic matrix switches in the fiber optic transmission system, multiple optical signals (all with the aforementioned specified transmission rates) can be routed between multiple video sources / displays. Moreover, since the fiber optic matrix switch simply forwards optical signals between corresponding input and output terminals without requiring additional signal processing / conversion, routing latency can be effectively reduced, thus enabling implementation at a lower cost.
