Technical Field

[0001] This application relates to the field of signal transmission technology, and in particular to a video transmission system, a video transmission device, and a video receiving device. Background Technology

[0002] In traditional video transmission systems, camera devices (such as surveillance cameras and industrial cameras) can be directly connected to the backend signal acquisition and processing equipment via coaxial cables. This architecture is simple and reliable, but in practical applications, coaxial cables are rigid and have limited transmission distances, making them unsuitable for long-distance video transmission in complex spaces. Because optical fibers are flexible and have extremely low signal loss, they are suitable for long-distance signal transmission in complex spaces.

[0003] To achieve long-distance fiber optic transmission of video signals, it is necessary to improve the hardware of the equipment based on the traditional video transmission system. With the improved hardware, technicians can further convert the raw video signals captured by the camera equipment into video optical signals suitable for fiber optic transmission through programming and other means.

[0004] However, existing technologies lack suitable hardware platforms for engineers to further develop and achieve long-distance fiber optic transmission of video signals. Therefore, there is an urgent need to provide a fiber optic-based video transmission hardware platform, enabling engineers to further design and implement long-distance fiber optic transmission of video signals. Utility Model Content

[0005] This invention provides a video transmission system, a video transmission device, and a video receiving device to at least solve the technical problem in the prior art where there is no suitable hardware platform for technicians to further develop and realize long-distance fiber optic transmission of video signals, thus making it impossible to achieve long-distance transmission of video signals.

[0006] According to a first aspect of this application, a video transmission system is provided, including a camera device, a video transmission device, and a video receiving device, wherein the video transmission device is communicatively connected to both the camera device and the video receiving device, and the video transmission device includes a first programmable circuit module and an electro-optical conversion module, wherein the first programmable circuit module is communicatively connected to both the camera device and the electro-optical conversion module; and the electro-optical conversion module is connected to the video receiving device via an optical fiber, for converting an electrical signal received from the first programmable circuit module into an optical signal suitable for optical fiber transmission, and transmitting the converted optical signal to the video receiving device via the optical fiber.

[0007] According to a second aspect of this application, a video transmission device is provided, including a deserializer, a first programmable circuit module, and an electro-optical conversion module. The first programmable circuit module is connected to both the deserializer and the electro-optical conversion module. The deserializer, connected to the first programmable circuit module, is used to receive a serial video signal from a serializer, deserialize the serial video signal, and transmit the deserialized video signal to the first programmable circuit module. The electro-optical conversion module is connected to a video receiving device via an optical fiber and is used to convert the electrical signal received from the first programmable circuit module into an optical signal suitable for optical fiber transmission, and transmit the converted optical signal to the video receiving device via the optical fiber.

[0008] According to a third aspect of this application, a video receiving device is provided, including an optoelectronic conversion module, a second programmable circuit module, an HDMI interface, and a video encoder. The second programmable circuit module is connected to the optoelectronic conversion module, and the optoelectronic conversion module is connected to a video transmission device via an optical fiber. The optoelectronic conversion module is used to convert an optical signal received from the optoelectronic conversion module into an electrical signal suitable for the second programmable circuit module and transmit the electrical signal to the second programmable circuit module. The HDMI interface and the video encoder are respectively connected to the second programmable circuit module.

[0009] This application provides a first programmable circuit module between the camera device and the electro-optical conversion module. The first programmable circuit module can convert the original video signal into an electrical signal compatible with the protocol applicable to the electro-optical conversion module. Therefore, when the electro-optical conversion module receives an electrical signal corresponding to the original video signal, it can convert the electrical signal into an optical signal suitable for long-distance optical fiber transmission.

[0010] Furthermore, since this application utilizes a camera device to connect with a video receiving device, and uses optical fiber to connect the video transmission device to the video receiving device, and transmits signals through optical fiber, compared with the existing use of rigid coaxial cables for signal transmission with limited transmission distance, the optical fiber used in this application not only has a certain degree of flexibility but is also suitable for long-distance transmission, thus adapting to more complex deployment environments and ensuring signal transmission distance.

[0011] Therefore, technicians can use the hardware platform based on the video transmission system provided in this application to develop and achieve long-distance transmission of video signals. This solves the technical problem in the prior art that there is no suitable hardware platform for technicians to further develop and achieve long-distance fiber optic transmission of video signals.

[0026] Figure 1 A schematic diagram of a video transmission system according to this embodiment is shown. According to a first aspect of this embodiment, a video transmission system 10 is provided. Specifically, refer to... Figure 1 As shown, the video transmission system 10 includes a camera device 100, a video transmission device 200, and a video receiving device 300, wherein the video transmission device 200 is communicatively connected to both the camera device 100 and the video receiving device 300. The video transmission device 200 includes a first programmable circuit module 220 and an electro-optical conversion module 230, wherein the first programmable circuit module 220 is communicatively connected to both the camera device 100 and the electro-optical conversion module 230; and the electro-optical conversion module 230 is connected to the video receiving device 300 via an optical fiber 500, for converting electrical signals received from the first programmable circuit module 220 into optical signals suitable for optical fiber transmission, and transmitting the converted optical signals to the video receiving device 300 via the optical fiber 500.

[0027] Specifically, firstly, the camera device 100 responds to a control command sent by the user via the video receiving device 300 and acquires the original video signal corresponding to the target object. Then, the camera device 100 transmits the original video signal to the video transmission device 200, where the first programmable circuit module 220 performs image processing and packetization operations on the original video signal, generating an electrical signal compatible with the protocol used by the electro-optical conversion module 230.

[0028] Furthermore, since the protocol applicable to the camera device 100 is different from the protocol applicable to the electro-optical conversion module 230, when the camera device 100 and the electro-optical conversion module 230 are directly connected, the electro-optical conversion module 230 cannot directly receive the original video signal and perform conversion processing on the original video signal. Therefore, this application adds a first programmable circuit module 220 between the camera device 100 and the electro-optical conversion module 230. The first programmable circuit module 220 can not only perform image processing and packetization operations on the original video signal, but also convert the original video signal into an electrical signal compatible with the protocol applicable to the electro-optical conversion module 230. Therefore, when the electro-optical conversion module 230 receives the electrical signal corresponding to the original video signal sent by the first programmable circuit module 220, it can convert the electrical signal into an optical signal suitable for transmission over the optical fiber 500, thereby realizing the conversion process from the original video signal output by the camera device 100 to an optical signal suitable for long-distance transmission over the optical fiber 500.

[0029] Finally, the electro-optical conversion module 230 transmits the optical signal corresponding to the original video signal to the video receiving device 300 via the optical fiber 500. Upon receiving the optical signal corresponding to the original video signal, the video receiving device 300 performs photoelectric conversion and format conversion on the received optical signal, ensuring that technicians can view or process the corresponding video images through the video receiving device 300. Therefore, compared to existing signal transmission methods using rigid coaxial cables with limited transmission distances, this application utilizes optical fiber for signal transmission, achieving the technical effect of ensuring long-distance signal transmission.

[0030] As described in the background section, in traditional video transmission systems, camera modules (such as surveillance cameras and industrial cameras) can be directly connected to the backend signal acquisition and processing equipment via coaxial cables. This architecture is simple and reliable; however, in practical applications, coaxial cables are rigid and have limited transmission distances, making them unsuitable for long-distance video transmission in complex spaces. Optical fiber, due to its flexibility and extremely low signal loss rate, is suitable for long-distance signal transmission in complex spaces. To achieve long-distance fiber optic transmission of video signals, hardware improvements are needed to the traditional video transmission system. This would allow technicians to further convert the video electrical signals acquired by the camera modules into optical video signals suitable for fiber optic transmission through programming and other methods. However, current technology lacks a suitable hardware platform for further development to achieve long-distance fiber optic transmission of video signals.

[0031] In view of this, the present application provides a first programmable circuit module between the camera device and the electro-optical conversion module. The first programmable circuit module can convert the original video signal into an electrical signal compatible with the protocol applicable to the electro-optical conversion module. Therefore, when the electro-optical conversion module receives an electrical signal corresponding to the original video signal, it can convert the electrical signal into an optical signal suitable for long-distance optical fiber transmission.

[0032] Furthermore, since this application utilizes a camera device to connect with a video receiving device, and uses optical fiber to connect the video transmission device to the video receiving device, and transmits signals through optical fiber, compared with the existing use of rigid coaxial cables for signal transmission with limited transmission distance, the optical fiber used in this application not only has a certain degree of flexibility but is also suitable for long-distance transmission, thus adapting to more complex deployment environments and ensuring signal transmission distance.

[0033] Therefore, technicians can use the hardware platform based on the video transmission system provided in this application to develop and achieve long-distance transmission of video signals. This solves the technical problem in the prior art that there is no suitable hardware platform for technicians to further develop and achieve long-distance fiber optic transmission of video signals.

[0034] Optionally, the camera device 100 includes an image sensor 110 and a serializer 120, and the video transmission device 200 includes a deserializer 210, wherein the serializer 120 and the deserializer 210 are connected via a coaxial cable 400, and wherein the serializer 120 is connected to the image sensor 110 for converting the raw video signal received from the image sensor 110 into a serial video signal and transmitting the serial video signal to the deserializer 210 via the coaxial cable 400; and the deserializer 210 is connected to a first programmable circuit module 220 for receiving the serial video signal from the serializer 120, deserializing the serial video signal, and transmitting the deserialized video signal to the first programmable circuit module 220.

[0035] Specifically, the camera device 100 includes an image sensor 110 and a serializer 120. The image sensor 110, in response to control commands sent by the user through the video receiving device 300, acquires the raw video signal corresponding to the video image.

[0036] The image sensor 110 then transmits the raw video signal to the serializer 120, which converts the raw video signal into a serial video signal and transmits it via the coaxial cable 400 to the deserializer 210 of the video transmission device 200. Upon receiving the serial video signal, the deserializer 210 performs deserialization processing on the serial video signal and converts it back into the raw video signal.

[0037] Finally, the deserializer 210 transmits the original video signal to the first programmable circuit module 220, which then performs further processing on the original video signal.

[0038] Thus, by setting a serializer 120 in the camera device 100 and a deserializer 210 connected to the serializer 120 in the video transmission device 200, the technical effect of ensuring long-distance video signal transmission is achieved.

[0039] Optionally, the first programmable circuit module 220 includes a first SOC chip 221, wherein the first SOC chip 221 is connected to the deserializer 210 and the electro-optical conversion module 230 respectively.

[0040] Specifically, refer to Figure 2 As shown, the first programmable circuit module 220 includes a first SOC chip 221, and the first SOC chip 221 includes a PL segment and a PS segment. The PL segment is used to convert the raw video signal into an electrical signal compatible with the protocol applicable to the electro-optical conversion module 230. The PL segment is also used for image processing of the raw video signal. The PS segment is used for transmitting control commands.

[0041] Specifically, when the PS terminal of the first SOC chip 221 receives a control command, it drives the PL terminal to perform image processing on the received raw video signal and convert the image-processed raw video signal into an electrical signal compatible with the protocol applicable to the electro-optical conversion module 230. Then, the PL terminal in the first SOC chip 221 can package the electrical signal in real time and send the corresponding data packet to the electro-optical conversion module 230 via the GTX interface.

[0042] Optionally, the first programmable circuit module 220 includes a first FPGA chip 222 and a first processor 223, wherein the first FPGA chip 222 is connected to the deserializer 210 and the electro-optical conversion module 230 respectively, and the first processor 223 is connected to the deserializer 210 and the first FPGA chip 222 respectively.

[0043] Specifically, refer to Figure 3 As shown, when the first processor 223 in the first programmable circuit module 220 receives a control command, it drives the first FPGA chip 222 to perform image processing on the raw video signal received from the deserializer 210, and converts the image-processed raw video signal into an electrical signal compatible with the protocol applicable to the electro-optical conversion module 230. Then, the first FPGA chip 222 packages the electrical signal in real time and sends the data packet corresponding to the electrical signal to the electro-optical conversion module 230 via the GTX interface.

[0044] Therefore, this application provides two different first programmable circuit modules (i.e., a first SOC chip 221 integrating PL and PS terminals, and a first FPGA chip 222 and a first processor 223, which are split into two different hardware components). In other words, technicians can use the different forms of the first programmable circuit module 220 to achieve image processing, conversion of raw video signals, and data packaging, thereby improving the technical effectiveness of the applicability of the hardware platform provided in this application.

[0045] Optionally, the video receiving device 300 includes a photoelectric conversion module 310 and a second programmable circuit module 320 connected to the photoelectric conversion module 310. The photoelectric conversion module 310 and the electro-optical conversion module 230 are connected via an optical fiber 500 to convert the optical signal received from the electro-optical conversion module 230 into an electrical signal suitable for the second programmable circuit module 320, and to transmit the electrical signal to the second programmable circuit module 320.

[0046] Specifically, refer to Figure 1 As shown, the original video signal acquired and output by the camera device 100 is processed by the first programmable circuit module 220 and converted into an electrical signal adapted to the electro-optical conversion module 230. The electro-optical conversion module 230 converts the electrical signal into an optical signal that can be transmitted through the optical fiber 500.

[0047] Furthermore, when the photoelectric conversion module 310 receives the optical signal corresponding to the original video signal from the video transmission device 200 via the optical fiber 500, it converts the optical signal into an electrical signal suitable for processing by the second programmable circuit module 320, and the second programmable circuit module 320 further processes the electrical signal corresponding to the original video signal.

[0048] Optionally, the second programmable circuit module 320 includes a second SOC chip 321, wherein the second SOC chip 321 is connected to the photoelectric conversion module 310.

[0049] Specifically, refer to Figure 2 As shown, the second programmable circuit module 320 includes a second SOC chip 321, and the second SOC chip 321 includes a PL terminal and a PS terminal. The PL terminal is used to convert electrical signals into raw video signals. The PS terminal is used to transmit control commands.

[0050] Specifically, when the PS terminal of the second SOC chip 321 receives the electrical signal converted by the photoelectric conversion module 310 through the GTX interface, it drives the PL terminal to decapsulate the data packet corresponding to the electrical signal and convert the electrical signal into the original video signal. Then, the PS terminal of the second SOC chip 321 transmits the original video signal to the video encoder 340 for image compression processing or to the HDMI interface 330 for output.

[0051] Optionally, the second programmable circuit module 320 includes a second FPGA chip 322 and a second processor 323 connected to the second FPGA chip 322, wherein the second FPGA chip 322 is connected to the photoelectric conversion module 310.

[0052] Specifically, refer to Figure 3 As shown, when the second processor 323 in the second programmable circuit module 320 receives the electrical signal converted by the photoelectric conversion module 310 through the GTX interface, it drives the second FPGA chip 322 to decapsulate the data packet corresponding to the electrical signal and convert the electrical signal into the original video signal. Then, the second processor 323 transmits the original video signal to the video encoder 340 for image compression processing or to the HDMI interface 330 for output.

[0053] Therefore, this application provides two different second programmable circuit modules (i.e., a second SOC chip 321 integrating PL and PS terminals, and a second FPGA chip 322 and a second processor 323 split into two different hardware components). In other words, technicians can use different forms of the second programmable circuit module 320 to achieve image processing, electrical signal conversion, and data transmission, thereby achieving the technical effect of improving the applicability of the hardware platform provided by this application.

[0054] Optionally, the video receiving device 300 also includes an HDMI interface 330 and a video encoder 340, which are respectively connected to the second programmable circuit module 320.

[0055] Specifically, refer to Figure 1 , Figure 2 or Figure 3 As shown, the second programmable circuit module 320, when converting electrical signals into raw video signals, can send the raw video signals to the video encoder 340, which then compresses the data corresponding to the raw video signals while maintaining visual quality. The second programmable circuit module 320 can also directly output the data corresponding to the raw video signals via the HDMI interface 330.

[0056] also, Figure 4 This is a schematic diagram of the internal structure of a video transmission device according to an embodiment of this application. (Reference) Figure 4 As shown, the PL terminal of the first SOC chip 221 can also perform the following functions: D-PHY and CSIRxIP can receive the raw video signal and convert it into AXI4-Stream video format. ISP (Image Signal Processor) is responsible for image processing of the raw video signal. AXI4-Stream Video Bridge is used to convert the raw video signal into an electrical signal compatible with the protocol applicable to the electro-optical conversion module. Video proc is used for hardware acceleration to meet low latency requirements. 10GEthernet Subsystem IP is used for data encapsulation and packaging.

[0057] Figure 5 This is a schematic diagram of the internal structure of a video receiving device according to an embodiment of this application. (Reference) Figure 5 As shown, the PL terminal of the second SOC chip 321 can also perform the following functions: the GTX interface is responsible for receiving electrical signals transmitted by the photoelectric conversion module 310; the 10G Ethernet Subsystem IP is used for data decapsulation; and the AXI4-Stream VideoBridge is used to convert electrical signals into raw video signals.

[0058] Those skilled in the art should note that the above is merely an example of how technicians can perform image processing and format conversion on the original video signal using the aforementioned module on the PL end, but the above content is not within the scope of protection of this application.

[0059] Figure 4 A schematic diagram of a video transmission device according to this embodiment is shown.

[0060] According to a second aspect of this embodiment, a video transmission device 200 is provided. Specifically, refer to... Figure 4 As shown, the video transmission device 200 includes a deserializer 210, a first programmable circuit module 220, and an electro-optical conversion module 230. The first programmable circuit module 220 is connected to both the deserializer 210 and the electro-optical conversion module 230. The deserializer 210 is connected to the first programmable circuit module 220 and is used to receive serial video signals from the serializer 120, deserialize the serial video signals, and transmit the deserialized video signals to the first programmable circuit module 220. The electro-optical conversion module 230 is connected to the video receiving device 300 via an optical fiber 500 and is used to convert the electrical signals received from the first programmable circuit module 220 into optical signals suitable for optical fiber transmission, and transmit the converted optical signals to the video receiving device 300 via the optical fiber 500.

[0061] Figure 5 A schematic diagram of the video receiving device described in this embodiment is shown.

[0062] According to a third aspect of this embodiment, a video receiving device 300 is provided. Specifically, refer to... Figure 5 As shown, the video receiving device 300 includes an optoelectronic conversion module 310, a second programmable circuit module 320, an HDMI interface 330, and a video encoder 340. The second programmable circuit module 320 is connected to the optoelectronic conversion module 310, and the optoelectronic conversion module 310 is connected to the video transmission device 200 via an optical fiber 500. It is used to convert the optical signal received from the optoelectronic conversion module 230 into an electrical signal suitable for the second programmable circuit module 320, and transmit the electrical signal to the second programmable circuit module 320. The HDMI interface 330 and the video encoder 340 are respectively connected to the second programmable circuit module 320.

[0063] Specifically, firstly, when the photoelectric conversion module 310 receives the optical signal corresponding to the original video signal from the video transmission device 200 via the optical fiber 500, it converts the optical signal into an electrical signal. Then, when the second programmable circuit module 320 receives the electrical signal, it decapsulates the corresponding data packets and converts the electrical signal back into the original video signal. Further, the second programmable circuit module 320 sends the original video signal to the video encoder 340, whereby the video encoder 340 performs image compression processing on the data corresponding to the original video signal while maintaining visual quality. The second programmable circuit module 320 can also directly output the original video signal via the HDMI interface 330.

[0064] Figure 6 A schematic diagram of a video transmission system for multiple cameras according to this embodiment is shown. Specifically, refer to... Figure 6 As shown, camera device 100a includes an image sensor 110a and a serializer 120a, and camera device 100b includes an image sensor 110b and a serializer 120b. Camera devices 100a and 100b are respectively connected to video transmission device 200 via coaxial cable 400. After being deserialized by deserializers 210a and 210b, the signals are transmitted to the first programmable circuit module 220. After processing by the first programmable circuit module 220, the signals are transmitted to the electro-optical conversion module 230 to realize the conversion of optical signals to electrical signals. The converted optical signals are then transmitted to video receiving device 300 via optical fiber 500.

[0065] Specifically, the video transmission system can be connected not only to a single camera device 100, but also to multiple camera devices (e.g., camera device 100a and camera device 100b). Furthermore, camera device 100a and camera device 100b can, for example, capture video images corresponding to different target objects, or capture video images of the same target object from different shooting angles.

[0066] For example, a video transmission system with multiple cameras can be applied in live streaming scenarios, where the first target object can be, for example, the anchor, and the second target object can be, for example, the item being explained by the anchor. The image sensor 110a in camera device 100a responds to control commands sent by the central control personnel via video receiving device 300 and acquires a close-up video image corresponding to the anchor; the image sensor 110b in camera device 100b responds to control commands sent by the central control personnel via video receiving device 300 and acquires a close-up video image corresponding to the item being explained by the anchor.

[0067] Therefore, in the above application scenario, image sensor 110a transmits the original video signal corresponding to the first target object to serializer 120a. Serializer 120a converts the original video signal into a serial video signal and transmits the serial video signal to deserializer 210a of video transmission device 200 via coaxial cable 400a. Simultaneously, image sensor 110b transmits the original video signal corresponding to the second target object to serializer 120b. Serializer 120b converts the original video signal into a serial video signal and transmits the serial video signal to deserializer 210b of video transmission device via coaxial cable 400b.

[0068] Therefore, when deserializer 210a receives a serial video signal corresponding to the first target object, it deserializes the serial video signal and converts it into the original video signal corresponding to the first target object. Similarly, when deserializer 210b receives a serial video signal corresponding to the second target object, it deserializes the serial video signal and converts it into the original video signal corresponding to the second target object.

[0069] Then, deserializers 210a and 210b transmit the original video signal corresponding to the first target object and the original video signal corresponding to the second target object to the first programmable circuit module 220, respectively.

[0070] Furthermore, the first programmable circuit module 220 further processes the original video signal corresponding to the first target object and the original video signal corresponding to the second target object (e.g., image fusion processing), and converts the processed original video signal into an electrical signal compatible with the protocol applicable to the electro-optical conversion module 230.

[0071] Finally, the electro-optical conversion module 230 converts the electrical signal into an optical signal that can be transmitted through the optical fiber 500, and transmits the converted optical signal to the video receiving device 300 through the optical fiber 500.

[0072] For example, the image sensor 110a in the camera device 110a acquires the original video signal corresponding to the first shooting angle of the target object, and the target object can be the anchor, and the first shooting angle corresponding to the target object can be the front of the anchor; the image sensor 110b in the camera device 110b acquires the original video signal corresponding to the second shooting angle of the target object, and the second shooting angle corresponding to the target object can be the side of the anchor.

[0073] Therefore, in the above application scenario, image sensor 110a responds to the control command sent by the central control personnel through video receiving device 300 and acquires the original video signal corresponding to the first shooting angle of the target object; image sensor 110b responds to the control command sent by the central control personnel through video receiving device 300 and acquires the original video signal corresponding to the second shooting angle of the target object.

[0074] Subsequently, image sensor 110a transmits the raw video signal corresponding to the first shooting angle to serializer 120a. Serializer 120a converts the raw video signal into a serial video signal and transmits it to deserializer 210a of video transmission device 200 via coaxial cable 400a. Simultaneously, image sensor 110b transmits the raw video signal corresponding to the second shooting angle to serializer 120b. Serializer 120b converts the raw video signal into a serial video signal and transmits it to deserializer 210b of video transmission device via coaxial cable 400b.

[0075] Therefore, when deserializer 210a receives a serial video signal corresponding to the first shooting angle, it deserializes the serial video signal and converts it into the original video signal corresponding to the first target object. Similarly, when deserializer 210b receives a serial video signal corresponding to the second shooting angle, it deserializes the serial video signal and converts it into the original video signal corresponding to the second shooting angle.

[0076] Then, deserializers 210a and 210b transmit the original video signal corresponding to the first shooting angle and the original video signal corresponding to the second shooting angle to the first programmable circuit module 220, respectively.

[0077] Furthermore, the first programmable circuit module 220 further processes the original video signal corresponding to the first shooting angle and the original video signal corresponding to the second shooting angle (e.g., image stitching processing), and converts the processed original video signal into an electrical signal compatible with the protocol applicable to the electro-optical conversion module 230.

[0078] Finally, the electro-optical conversion module 230 converts the electrical signal into an optical signal that can be transmitted through the optical fiber 500, and transmits the converted optical signal to the video receiving device 300 through the optical fiber 500.

[0079] Therefore, the video transmission device 200 of this application supports connection to multiple camera devices 100a and 100b, and can support simultaneous input of multiple raw video signals corresponding to different camera devices 100a and 100b. Furthermore, when the video transmission device 200 simultaneously receives raw video signals sent by different camera devices 100a and 100b, it can simultaneously perform image processing and conversion operations on multiple raw video signals. This achieves the technical effect of improving signal processing efficiency.

[0080] Furthermore, since the video transmission device 200 of this application can connect to different numbers of camera devices 100a and 100b (i.e., one camera device or multiple camera devices), users (e.g., broadcasters or central control personnel) can select the number of camera devices 100a and 100b according to actual usage. This achieves the technical effect of improving the applicability of the video transmission device 200.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0082] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0083] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0084] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
