[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0029] First, some nouns or terms that appear in the description of the embodiments of this application shall be interpreted as follows:

[0030] SERDES: Short for SERializer / DESerializer, it is a mainstream time-division multiplexing (TDM) point-to-point (P2P) serial communication technology. At the transmitting end, multiple low-speed parallel signals are converted into high-speed serial signals, transmitted through a medium (optical fiber or copper wire), and finally converted back into low-speed parallel signals at the receiving end. This point-to-point serial communication technology fully utilizes the channel capacity of the transmission medium, reduces the required transmission channels and the number of device pins, increases signal transmission speed, and thus significantly reduces communication costs.

[0031] The splicing control device inserts input and output cards. The input card receives video data sent from the upstream device, processes it further, and then sends the processed video data to the display screen via the output card. However, in related technologies, the card slots on the splicing control device are fixed; only input cards can be inserted into the corresponding slot, and only output cards can be inserted into the corresponding slot. When the display system needs to add more displays, requiring additional input or output cards, the splicing control device cannot flexibly adapt to different scenario requirements.

[0032] To address the technical problem in related technologies where the card slots corresponding to the input and output cards are fixed during data transmission in splicing control devices, resulting in poor flexibility of the devices, this utility model provides a card-insertion type video processing device.

[0033] Figure 1 This is a structural block diagram of a card-type video processing device according to an embodiment of the present utility model, such as... Figures 1 to 5 As shown, the card-type video processing device includes a transmission module 10 and a processing module 11. The transmission module is connected to the processing module. The transmission module includes a card slot 101 and a video transmission board 102 inserted into the card slot. The card slot includes a mixed-insertion card slot 20. When the video transmission board is inserted into the mixed-insertion card slot with a first connection relationship, the video transmission board is used to send data. When the video transmission board is inserted into the mixed-insertion card slot with a second connection relationship, the video transmission board is used to receive data.

[0034] Specifically, the card-type video processing equipment can be a video conferencing control device. This device can communicate with upstream equipment via a transmission module and receive video data; secondly, it can use a processing module to further process the received video data; and finally, it can communicate with the display screen via the transmission module and send the processed data to be displayed on the screen.

[0035] The plug-in video processing device includes a mixed-insert card slot, which supports multiple insertion methods. When a video transmission card is inserted into the mixed-insert card slot with a first connection relationship, the video transmission card acts as an output card and can be used to send data. Similarly, when a video transmission card is inserted into the mixed-insert card slot with a second connection relationship, the video transmission card acts as an output card and is used to receive data.

[0036] In other words, in practical applications, when more output card slots are needed, the mixed-use card slot can be used as an output card slot. When the actual application scenario changes, and the number of required output card slots decreases while the number of input card slots increases, the mixed-use card slot can be used as an input card slot.

[0037] Optionally, the mixed-insertion card slot includes a first connector, a second connector, and a third connector. The first connection relationship is that the video transmission board is connected to the first connector and the second connector, and the second connection relationship is that the video transmission board is connected to the first connector and the third connector.

[0038] Figure 2 This is a schematic diagram of an optional mixed-insertion card slot according to an embodiment of the present utility model, as shown below. Figure 2 As shown, the mixed-use card slot may include a first connector 201, a second connector 202, and a third connector 203. The first connection relationship is that the video transmission board is inserted into the mixed-use card slot through the first and second connectors; the second connection relationship is that the video transmission board is inserted into the mixed-use card slot through both the first and third connectors. Specifically, the mixed-use card slot may include three rows of connectors: the first row contains the first connector, the second row contains the second connector, and the third row contains the third connector. The video transmission board may connect only to the first and second rows of connectors, or only to the first and third rows of connectors, but it cannot connect to all three rows of connectors simultaneously.

[0039] Optionally, the card slot further includes an output card slot, which includes a first connector and a second connector. When the video transmission board is connected to the first connector and the second connector, the video transmission board is used to transmit data. Optionally, the card slot further includes an input card slot, which includes a first connector and a third connector. When the video transmission board is connected to the first connector and the third connector, the video transmission board is used to receive data.

[0040] Figure 3 This is a schematic diagram of an optional card slot according to an embodiment of the present utility model, such as... Figure 3As shown, the transmission module of the card-type video processing device, in addition to a mixed-insertion card slot, can also have a dedicated input card slot 21 and a dedicated output card slot 22. The output card slot includes a first connector and a second connector, while the input card slot includes a first connector and a third connector. Specifically, the dedicated card slot only includes two rows of connectors; that is, the output card only includes the first and second rows of connectors, and the input card only includes the first and third rows of connectors.

[0041] Optionally, there can be multiple video transmission cards. The number of video output cards, mixed-use card slots, and dedicated input and output card slots can be flexibly configured according to requirements to meet the high bandwidth needs of practical applications.

[0042] Optionally, the video transmission board includes a board connector connected in series, multiple FPGAs, and an optical port transmission circuit, which is used to convert between optical signals and electrical signals.

[0043] Figure 4 This is a schematic diagram of an optional video transmission board according to an embodiment of the present utility model, as shown below. Figure 4 As shown, the video transmission board includes a board connector 41, which can be connected board-to-board (i.e., B to B connection) with the connector board in the card slot. The video transmission board may also include multiple FPGAs, which can encode and process the video signal separately. The original video signal is greatly optimized during processing, reducing buffered images, thereby optimizing device latency, preserving the image quality of the original video signal, and reducing image quality degradation caused by different video encodings. Using multiple FPGAs to complete video signal processing and synchronous transmission reduces the performance requirements of FPGAs, making FPGA selection more flexible, and also reducing FPGA power consumption. At the same time, using multiple FPGAs makes heat dissipation easier and increases operational reliability. The video transmission board may also include an optical port transmission circuit 44, which uses the optical port transmission circuit to transmit the video electrical signal processed by the FPGA in real time. The video electrical signal is directly output and transmitted after electro-optical conversion after FPGA processing, without the need for Ethernet protocol conversion, simplifying system design, reducing system latency, and making field wiring and maintenance more convenient.

[0044] Optionally, multiple FPGAs can be configured as two, wherein the first FPGA is used to perform video layer processing on the video signal output by the processing module, and the second FPGA is used to encode the video data output by the first FPGA.

[0045] Optionally, the video transmission board also includes a memory connected to multiple FPGAs for storing data generated by the multiple FPGAs.

[0046] Optionally, the video signal output by the processing module is SerDes data.

[0047] Preferably, multiple FPGAs can be implemented in pairs. The first FPGA primarily deserializes the SerDes video signal provided by the output card slot of the video conferencing device and performs video layer processing. The second FPGA further processes the received video signal processed by the first FPGA and performs encoding output. Correspondingly, when receiving data, the FPGA can also perform corresponding reverse decoding processing. Figure 5 This is a schematic diagram of another optional video transmission board according to an embodiment of the present utility model, such as... Figure 5 As shown, the FPGA can also be connected to the memory 51 to support the normal operation of the FPGA and store relevant data during the processing.

[0048] Optionally, multiple optical port transmission circuits can be used. The number of optical port transmission circuits can also be set according to actual needs to meet the user's requirements for high bandwidth and diverse application scenarios.

[0049] By setting a mixed-insertion card slot in the card slot, when the video transmission board is inserted into the mixed-insertion card slot with the first connection relationship, the video transmission board is used to send data; when the video transmission board is inserted into the mixed-insertion card slot with the second connection relationship, the video transmission board is used to receive data. This achieves the purpose of the mixed-insertion card slot being able to insert both input cards and output cards, thereby realizing the technical effect of improving the flexibility of the splicing control equipment. It also solves the technical problem in related technologies where the card slots corresponding to the input cards and output cards are fixed when the splicing control equipment transmits data, resulting in poor flexibility of the splicing control equipment.
