[0031] At present, video processing equipment usually adopts a plug-in card architecture, in which multiple input card slots are connected in series. If any input card slot is not inserted with an input card, the video data in the video processing device cannot be transmitted normally, and the preview module cannot receive video data, resulting in abnormal preview function.

[0032] In order to solve the above problems, this application proposes a video processing method, please refer to Figure 1 , Figure 1 The video processing method of this embodiment is applied to a plug-in video processing device, which can be a personal computer, a professional workstation, a server, a monitoring system, a cinema equipment, a broadcasting equipment, a medical device, an industrial vision system, etc.

[0033] See also Figure 2 , Figure 2 1 is a schematic diagram of the structure of an embodiment of a plug-in card video processing device of the present application. The plug-in card video processing device 300 includes N input card slots 310, N bypass modules 320 and a pre-monitoring module 330, wherein the N input card slots 310 include a first input card slot 311, a second input card slot 311, ..., an n-1th input card slot 312, an nth input card slot 313 and an Nth input card slot 314; the N bypass modules 320 include a first bypass module 321, a second bypass module 321, ..., an n-1th bypass module 322, an nth bypass module 323 and an Nth bypass module 324. N bypass modules 320 are connected in series in sequence, the pre-monitoring module 330 is connected to the Nth bypass module 324, and the nth input card slot 313 is connected to the nth bypass module 323 in parallel, that is, the N input card slots 310 are arranged in one-to-one correspondence with the N bypass modules 320, and n is an integer greater than 1 and less than or equal to N.

[0034] The nth bypass module 323 receives the n-1th superimposed video data, and generates the first video data and the second video data based on the n-1th superimposed video data, wherein the first video data and the second video data are the same. When the nth input card slot 313 is inserted with an input card, the input card receives the first video data and the nth video data, and superimposes the first video data and the nth video data to obtain the nth superimposed video data. The pre-monitoring module 330 receives the Nth level superimposed video data from the Nth bypass module 324, and performs pre-monitoring display based on the Nth level superimposed video data.

[0035] See also Figure 1 , the video processing method may include the following steps:

[0036] Step S11: receiving the n-1th superimposed video data through the n-1th bypass module, and generating first video data and second video data based on the n-1th superimposed video data, wherein the first video data and the second video data are the same.

[0037] Optional, see Figure 2 Each of the N bypass modules 320 may include a signal distributor, which is used to transmit, convert, isolate, and distribute the received signal to different control systems to achieve the function of one-input and multiple-output of industrial signals. In this embodiment, a one-input and two-output signal distributor may be selected, which receives the n-1th superimposed video data and generates the first video data and the second video data based on the n-1th superimposed video data.

[0038] In this example, see Figure 2 The n-1th bypass module 322 is connected to the n-1th bypass module 323, the n-1th bypass module 322 sends the n-1th overlay video data to the n-1th bypass module 323, and the signal distributor in the n-1th bypass module 323 generates the first video data and the second video data based on the n-1th overlay video data, wherein the first video data and the second video data are the same.

[0039] Step S12: in response to the input card being inserted into the nth input card slot, the first video data and the nth video data are received through the input card, and the first video data and the nth video data are superimposed to obtain the nth superimposed video data.

[0040] In some embodiments, the input card can receive the nth video data input from one or more external input devices, where the external input devices may include IPC (IP Camera), SDI (serial digital interface) cameras, etc., which is not limited in this application.

[0041] See also Figure 2 , the nth input card slot 313 is connected to the nth bypass module 323, and the first video data generated by the nth bypass module 323 can be received through the nth input card slot 313. In some embodiments, when an input card is inserted into the nth input card slot 313, the nth input card slot 313 receives the first video data, and the input card receives the first video data through the nth input card slot 313. In other embodiments, when no input card is inserted into the nth input card slot 313, the nth bypass module 323 uses the second video data as the nth superimposed video data.

[0042] Optionally, the overlay processing may include video picture overlay processing, image and text overlay processing, layer blending overlay processing, etc.

[0043] In some embodiments, the overlay processing may include video picture overlay processing, for example, merging the first video data and the nth video data into one display picture to obtain the nth overlay video data.

[0044] In some embodiments, the overlay processing may include text and image overlay processing, for example, the nth video data may be text or pattern, specifically, may include static text, real-time bullet screen information, audience interaction information, real-time game scores, trademark patterns, etc. The nth video data is set above the first video data to obtain the nth overlay video data.

[0045] In some embodiments, the overlay processing may include layer blending overlay processing, for example, mixing the first video data with the nth video data according to a preset ratio and preset transparency to obtain the nth overlay video data.

[0046] Step S13: receiving the Nth superimposed video data through the preview module, and performing preview display based on the Nth superimposed video data.

[0047] In this embodiment, please refer to Figure 2 The preview module 330 is connected to the Nth bypass module 324 to receive the Nth superimposed video data.

[0048] Optionally, the pre-monitoring module 330 may include a pre-monitoring card and a pre-monitoring card slot. The pre-monitoring card may be inserted into the pre-monitoring card slot, receive the Nth superimposed video data, and perform pre-monitoring display based on the Nth superimposed video data. In some embodiments, the pre-monitoring card may send the Nth superimposed video data to a host computer, and perform pre-monitoring display by the host computer. Wherein, the host computer may be a personal computer, a handheld device, a portable device, a tablet device, etc., and this application does not limit this.

[0049] In some embodiments, see Figure 2When the pre-monitoring card is inserted into the pre-monitoring card slot, the pre-monitoring card slot is connected to the Nth bypass module, the pre-monitoring card receives the Nth superimposed video data through the pre-monitoring card slot, sends the Nth superimposed video data to the host computer, and performs pre-monitoring display through the host computer.

[0050] In this embodiment, please refer to Figure 2 , the nth bypass module 323 of the card-insertion video processing device 300 receives the n-1th superimposed video data, and generates the first video data and the second video data based on the n-1th superimposed video data. When the nth input card slot 313 is inserted with an input card, the nth input card slot 313 receives the first video data, the input card receives the first video data through the nth input card slot 313, receives the nth video data through an external input device, and superimposes the first video data and the nth video data to obtain the nth superimposed video data; when the nth input card slot 313 is not inserted with an input card, the nth bypass module 323 uses the second video data as the nth superimposed video data. When the nth input card slot 313 is inserted with an input card or when no input card is inserted with an input card, the superimposed video data output by the input card can be normally transmitted through the nth bypass module 323, which can avoid the situation where the pre-monitoring module fails, and improve the efficiency of the card-insertion video processing device 300.

[0051] See also Figure 3 , Figure 3 yes Figure 1 A flow chart of an embodiment before step S11 in FIG. The steps before step S11 include the following steps:

[0052] Step S21: in response to the first input card slot being inserted with an input card, first video data is received through the input card, and the first video data is used as first superimposed video data through a first bypass module.

[0053] See also Figure 2 , the first input card slot 311 is connected to the first bypass module 321. In some embodiments, when an input card is inserted into the first input card slot 311, the input card receives the first video data input by the external input device. The first input card slot 311 sends the first video data to the first bypass module 321. The first bypass module 321 receives the first video data and uses the first video data as the first superimposed video data.

[0054] Step S22: In response to the first input card slot not being inserted with an input card, an input card is inserted into the nth input card slot, the first video data is received through the input card, and the first video data is used as the first superimposed video data through the nth bypass module.

[0055] See also Figure 2, the first input card slot 311 is connected to the first bypass module 321, and the nth input card slot 313 is connected to the nth bypass module 323. In some embodiments, when the first input card slot 311 is not inserted with an input card, and the nth input card slot 313 is inserted with an input card, the input card receives the first video data input by the external input device. The nth input card slot 313 sends the nth video data to the nth bypass module 323. The nth bypass module 323 receives the first video data and uses the first video data as the first superimposed video data.

[0056] Optionally, in this embodiment, the input card slot with the smallest number among all the input card slots into which the input cards are inserted can be selected as the nth input card slot 313, and the first video data can be received through the nth bypass module 323 connected to the nth input card slot 313, and the first video data can be used as the first superimposed video data.

[0057] See also Figure 4 , Figure 4 It is a structural schematic diagram of another embodiment of the plug-in card type video processing device of the present application. Figure 4 The plug-in video processing device 500 includes Figure 2 The control module 340 includes N input card slots 310, N bypass modules 320 and a pre-monitoring module 330, as well as the connection relationship and function definition between each module, and also includes a control module 340, which is connected to each bypass module and each input card slot, respectively, for obtaining the state of each input card slot, and controlling each corresponding bypass module based on the state of each input card slot. The control module 340 establishes a preset network, and monitors whether a registration address appears in the preset network. In the case where a registration address appears in the preset network, a preset instruction is sent based on the registration address, and it is determined whether a response instruction appears in the preset network. In the case where a response instruction appears in the preset network, the control module 340 inserts an input card into the nth input card slot 313, and the control module 340 controls the nth bypass module 323 to receive the nth superimposed video data; in the case where a response instruction does not appear in the preset network, the nth input card slot is not inserted with an input card, and the control module 340 controls the nth bypass module 323 to receive the second video data.

[0058] See also Figure 5 , Figure 5 yes Figure 1 A flow chart of an embodiment after step S11 in FIG. The following steps are included after step S11:

[0059] Step S31: Establish a preset network through the control module, and monitor whether a registered address appears in the preset network.

[0060] Optional, see Figure 4The control module 340 may include a switch device or a router device, wherein the switch is used to connect network devices and terminal devices; the router is used to realize the interconnection between local area networks, which is not limited in this application.

[0061] See also Figure 4 The control module 340 is used to build a preset network, and the N input card slots 310 and the N bypass modules 320 are respectively connected through the preset network. In some embodiments, when an input card is inserted into the nth input card slot 313 among the N input card slots 310, the nth input card slot 313 registers an address in the preset network based on a preset method, wherein the registered address can be a MAC (Media Access Control Address) of the input card slot.

[0062] The registered address can be a MAC address, which is also called a physical address or hardware address. It is an address code burned into the network card by the network device manufacturer during production. It can be used to confirm the location of the network device.

[0063] Step S32: In response to the presence of a registration address in the preset network, a preset instruction is sent based on the registration address, and it is determined whether a response instruction appears in the preset network.

[0064] When the control module 340 detects that a new registration address appears in the preset network, a preset instruction is sent based on the registration address. When the nth input card slot 313 is normally inserted with an input card, the nth input card slot 313 sends a corresponding response instruction to the preset network based on the preset instruction, and the control module 340 detects that a response instruction appears in the preset network; when the nth input card slot 313 is not normally inserted with an input card, the nth input card slot 313 does not send a corresponding response instruction, for example, the nth input card slot 313 is not inserted with an input card, and for another example, the nth input card slot 313 is not normally inserted with an input card, specifically, the nth input card slot 313 and the input card are abnormally connected and cannot exchange data normally.

[0065] Step S33: In response to a response instruction from the preset network, an input card is inserted into the nth input card slot.

[0066] When the control module 340 detects that a response instruction appears in the preset network, the control module 340 determines that an input card is inserted into the nth input card slot 313. In some embodiments, the control module 340 controls the nth input card slot 313 to receive the first video data. In other embodiments, the control module 340 controls the nth bypass module 323 to send the first video data to the nth input card slot 313.

[0067] Step S34: In response to the default network not receiving a response instruction, the nth input card slot has no input card inserted therein.

[0068] When the control module 340 detects that the preset network has no response command, the control module 340 determines that no input card is inserted into the nth input card slot 313. In some embodiments, the control module 340 controls the nth bypass module 323 to use the second video data as the nth superimposed data.

[0069] See also Figure 6 , Figure 6 Schematic diagram of the structure of an embodiment of each bypass module in the N bypass modules of the present application. The bypass module 710 includes a first processing module 711 and a second processing module 712 connected in series, the first processing module 711 is connected to one end of the corresponding input card slot 720, and the second processing module 712 is connected to the other end of the corresponding input card slot 720.

[0070] In some embodiments, see Figure 2 and Figure 6 The first processing module 711 in the nth bypass module 323 is used to generate the first video data and the second video data from the n-1th superimposed video data. When an input card is inserted into the nth input card slot 313, the first processing module 711 transmits the first video data to the nth input card slot 313; when no input card is inserted into the nth input card slot 313, the first processing module 711 transmits the second video data to the second processing module 712 in the nth bypass module.

[0071] Optionally, the first processing module 711 may be a signal distributor, which is used to transmit, convert, isolate, and distribute the received signal to different control systems to achieve a one-input and multiple-output function for industrial signals. In this embodiment, a one-input and two-output signal distributor may be selected, which receives the n-1th superimposed video data and generates the first video data and the second video data based on the n-1th superimposed video data.

[0072] In some embodiments, see Figure 2 and Figure 6 The second processing module 712 in the nth bypass module 323 is used to receive the nth superimposed video data or the second video data. When an input card is inserted into the nth input card slot 313, the second processing module 712 receives the nth superimposed video data; when no input card is inserted into the nth input card slot 313, the second processing module 712 receives the second video data and uses the second video data as the nth superimposed video data.

[0073] In some embodiments, see Figure 4 and Figure 6, the control module 340 is connected to the second processing module 712, and controls the second processing module 712 to receive the nth superimposed video data or the second video data. For example, when an input card is inserted into the nth input card slot 313, the control module 340 controls the second processing module 712 to receive the nth superimposed video data. For another example, when no input card is inserted into the nth input card slot 313, the control module 340 controls the second processing module 712 to receive the second video data, and uses the second video data as the nth superimposed video data.

[0074] Optionally, the second processing module 712 may be a signal selector, which is a device for selecting one of two or more received signals. In this embodiment, a two-choice signal selector may be selected. When an input card is inserted into the nth input card slot 313, the control module 340 controls the two-choice signal selector to receive the nth superimposed video data; when no input card is inserted into the nth input card slot 313, the control module 340 controls the two-choice signal selector to receive the second video data, and uses the second video data as the nth superimposed video data.

[0075] See also Figure 7 , Figure 7 810 is a schematic diagram of another embodiment of each bypass module in the N bypass modules of the present application. Each bypass module 810 may include a first port 811, a second port 812, a third port 813 and a fourth port 814. Figure 2 and Figure 7 , the third port 813 of the nth bypass module 323 is connected to the input end of the nth input card slot 313, the first port 811 is connected to the output end of the input card slot 820, and the second port 812 is connected to the fourth port 814 of the n-1th bypass module 322. In some embodiments, when an input card is inserted into the nth input card slot 313, the second port 812 of the nth bypass module 323 is connected to the third port 813, and the first port 811 of the nth bypass module 323 is connected to the fourth port 814.
