Description

Technical Field

[0001] The present application relates to the field of video acquisition, and in particular to a video acquisition method and system. Background Art

[0002] When using a game console or computer to play games or live video, when there is a need to take screenshots, record the screen or live broadcast, the built-in screen recording or live broadcast software of the device is often used to capture the screen or video on the display screen. If the screen recording or live broadcast software is running, the system performance will be consumed during video encoding, and the performance of the device will be occupied, causing the game or interface to be stuck, resulting in uneven quality of the recorded video and possible stuck screens. At the same time, users can only take screenshots or record specific video streams through additional devices, which makes it impossible for users to take into account the operating devices such as game controllers they are using. This makes it difficult for users to obtain accurate and effective video or picture materials that can be used during the continuous output of video streams. Summary of the invention

[0003] In view of this, the present invention proposes a video acquisition method and system, and the specific scheme is as follows:

[0004] A video acquisition method is applied to a loop-out collector, wherein the loop-out collector is connected to a video source device, an output device, and a terminal. The method comprises:

[0005] Obtain at least one source video signal from a video source device, process the source video signal to obtain a first video stream, and simultaneously copy the first video stream to obtain a second video stream;

[0006] sending a first video stream to an output device;

[0007] If a preset processing instruction is received, the second video stream is processed according to the preset processing instruction to obtain processed content, and the processed content is stored;

[0008] If a preset call instruction is received, part or all of the processed content is read according to the preset call instruction and sent to the terminal.

[0009] In some specific embodiments, “processing the source video signal to obtain a first video stream” includes:

[0010] Determine the display parameters of the output device that is pre-connected to the video source device; the display parameters include: resolution, refresh rate, response time, and whether HDR supports one or more of the parameters;

[0011] The source video signal is processed based on the display parameters of the output device to obtain a first video stream matching the display parameters of the output device.

[0012] In some specific embodiments, it also includes an operating device connected to the loop-out collector by wire or wirelessly; the preset processing instructions are generated by the operating device in response to the user's operation; the preset processing instructions include voice instructions generated in response to the user's preset voice and trigger instructions generated by the corresponding user touch or press operation.

[0013] By responding to user needs in a variety of ways, the user's operation methods can be more diverse and the user will not miss the screen that needs to be captured.

[0014] In some specific embodiments, the preset processing instructions include: instructions for taking screenshots or instructions for capturing videos.

[0015] In a specific embodiment, the instruction for taking a screenshot includes: the coordinates of the screenshot, and / or the range of the screenshot, and / or the time of the screenshot, and / or the resolution of the screenshot, and / or a post-adjustment operation on the screenshot;

[0016] The instruction for capturing a video includes: a time range for capturing a video, and / or a frame rate for capturing a video, and / or a resolution for capturing a video, and / or a time for capturing a video, and / or a sound for capturing a video, and / or a coding format for capturing a video, and / or a post-processing adjustment operation for the captured video;

[0017] In a specific embodiment, it also includes instructions for obtaining audio, and the instructions for obtaining audio include: obtaining the time range of the audio, and / or obtaining the volume value of the audio, and / or obtaining the encoding format of the audio, and / or post-adjustment operations on the obtained audio.

[0018] In actual applications, the user can set various parameters in the preset processing instructions in advance so that the user can quickly capture the video or take a screenshot with one click when the output device such as a display presents the picture in real time.

[0019] In some specific embodiments, it also includes:

[0020] Performing content recognition on the second video stream using an AI model for image recognition;

[0021] If the current picture of the second video stream meets the preset requirements, a screenshot or video capture processing is performed on the current picture, and the content obtained by the screenshot or video capture processing is used as the processed content to perform the operation of "storing the processed content".

[0022] In actual applications, by using an AI model for image recognition to identify the content of the second video stream, users can preset the images they want to obtain, such as presetting the game page to obtain the results or taking screenshots or video captures of the screen when a specific game character appears. By identifying the content of the second video stream and automatically extracting the content that meets the preset requirements, it can effectively help users to perform preliminary screening and storage of the screen, avoiding users forgetting to issue preset processing instructions during the game.

[0023] By identifying the content of the second video stream and automatically extracting the content that meets the preset requirements, it can effectively help users to perform preliminary screening and storage of the images, avoiding users forgetting to issue preset processing instructions during the game or live broadcast. By automatically capturing the images preset by the user, the user can obtain a preliminary rough cut after the entire game or live broadcast is over. Compared with the user manually issuing screenshot or recording instructions, by using the AI ​​model to match the user's preset parameters, the efficiency of the video or screenshot that the user finally obtains can be greatly improved, effectively reducing the difficulty of the user's later post-processing of the obtained video or screenshot, and improving the availability of the material.

[0024] In some specific embodiments, after receiving the preset processing instruction, the method further includes:

[0025] Send prompt information to the terminal, and / or the output device, and / or the operating device; the prompt information includes a graphical interface and / or prompt sound information.

[0026] In some specific embodiments, “reading part or all of the processed content according to a preset calling instruction and sending it to the terminal” includes:

[0027] Read the processed content of the preset time period before the current one according to the preset calling instruction, and send the read processed content to the terminal; or

[0028] Controlling the display of stored processed content on an output device, determining the processed content selected based on a preset calling instruction, and sending the determined processed content to a terminal.

[0029] In actual applications, the preset call instructions include operations such as copying, and / or cutting, and / or editing, and / or forwarding, and the user can select the required processed content according to their own needs.

[0030] In a specific embodiment, the processed content can be identified by an AI model for identifying content, and content keywords or content keywords can be extracted to tag the processed content with keywords. For example, if a user-preset character or scene appears in a video or picture clip, the video or picture clip is labeled with the character or scene or the user-preset keyword, so that the user can quickly filter by tags at a later stage to find the processed content that meets his preset needs.

[0031] In some specific embodiments, before “receiving a preset call instruction”, the process further includes:

[0032] Send matching requirements to the loop-out collector through the terminal to match the terminal with the loop-out collector;

[0033] When there are multiple terminals, the preset priority of each terminal is obtained, and the order in which the determined processed content is sent to the terminal is adjusted according to the priority;

[0034] Or adjust the permissions of the content that the terminal can receive according to the corresponding priority of the terminal.

[0035] In the second aspect, a video acquisition system is proposed, which is as follows:

[0036] A video acquisition system, applicable to any of the video acquisition methods in the above technical solutions, comprising: a loop-out collector, the loop-out collector is connected to a video source device, an output device and a terminal;

[0037] The loop-out collector includes:

[0038] A receiving unit, the receiving unit is used to obtain at least one source video signal from a video source device, process the source video signal to obtain a first video stream, and simultaneously copy the first video stream to obtain a second video stream;

[0040] A collection unit, the collection unit is used to receive a preset processing instruction, and process the second video stream according to the preset processing instruction to obtain processed content;

[0041] A storage unit, the storage unit is used to store the processed content;

[0042] The second output unit is used to receive a preset calling instruction, read part or all of the processed content from the storage unit according to the preset calling instruction, and send it to the terminal.

[0043] In some specific embodiments, the loop-out collector is connected to an operating device; the loop-out collector further includes a matching unit, the matching unit being used to match the collection unit with the operating device;

[0044] and / or for matching the first output unit with an output device;

[0045] and / or for matching the second output unit with the terminal.

[0046] In a specific embodiment, the video source device may be a game console or handheld game console including PS5 (PlayStation5), and / or NS (Nintendo Switch), and / or XBOX (Xbox Series X).

[0047] In actual applications, a game console or handheld game console can be directly connected to an output device such as a display via a signal line to achieve screen expansion; at this time, in order to capture the screen of the game console, the signal line is connected to the receiving unit of the loop-out collector, and then connected to the display through a video cable from the first output unit of the loop-out collector; at this time, the screen of the game handheld game console first enters the receiving unit of the loop-out collector, and the receiving unit performs preliminary processing on the source video signal.

The user can connect the game controller of the acquisition unit via an external Bluetooth to output preset processing instructions, and the acquisition unit obtains the processed content according to the preset processing instructions, wherein the processed content can be a video clip or a screenshot, and these processed contents will be stored in the storage unit.

[0048] Furthermore, the user can send a preset call instruction to the storage unit through the terminal to call or view the processed content from the storage unit. Therefore, through this video acquisition system, it is possible to implement specific interception and saving operations for the video or picture screen appearing in the output device, and at the same time, there is no delay in the content output of the output device such as a display screen. In actual applications, the first video stream and the second video stream obtained from the source video signal do not interfere with each other in operation and flow direction, and are independently processed and output.

[0059] Example 1

[0060] This embodiment proposes a video acquisition method, which can solve the user's need to synchronously capture specific video content when the video source device continuously outputs the video, as follows:

[0061] The invention is applied to a loop-out collector 1, which is connected to a video source device 2, an output device 3 and a terminal 4. Figure 1 As shown, the method includes:

[0062] S100, obtaining at least one source video signal from a video source device 2;

[0063] S200, processing a source video signal to obtain a first video stream;

[0064] S210, simultaneously copying the first video stream to obtain a second video stream;

[0065] S300, sending the first video stream to output device 3;

[0066] S400: If a preset processing instruction is received, the second video stream is processed according to the preset processing instruction to obtain processed content, and the processed content is stored;

[0067] S500 , if a preset calling instruction is received, read part or all of the processed content according to the preset calling instruction, and send it to the terminal 4 .

[0068] In some specific embodiments, Figure 2 As shown, in step S200, "processing the source video signal to obtain a first video stream" includes:

[0069] S201, determining display parameters of an output device 3 that is pre-connected to a video source device 2; the display parameters include: one or more of resolution, refresh rate, response time, and whether HDR supports the parameters;

[0070] S202 . Process the source video signal based on the display parameters of the output device 3 to obtain a first video stream matching the display parameters of the output device 3 .

[0071] By processing the source video signal based on the display parameters of the output device 3, the first video stream obtained based on the source video signal can be well adapted to the output device 3. When there are multiple output devices 3, it can effectively adapt to output devices 3 of different sizes or specifications.

[0072] In some specific embodiments, an operating device 5 connected to the loop collector 1 by wire or wireless is also included. The preset processing instruction is generated by the operating device 5 in response to the user's operation; the preset processing instruction includes a voice instruction generated in response to the user's preset voice and a trigger instruction generated by the corresponding user touch or press operation. Responding to the user's needs in a variety of ways makes the user's operation method more diverse and will not miss the screen that needs to be captured.

[0073] In some specific embodiments, the preset processing instructions include: instructions for taking screenshots or instructions for capturing videos.

[0074] In a specific embodiment, the instruction for taking a screenshot includes: the coordinates of the screenshot, and / or the range of the screenshot, and / or the time of the screenshot, and / or the resolution of the screenshot, and / or a post-adjustment operation on the screenshot;

[0075] The instruction for capturing a video includes: a time range for capturing a video, and / or a frame rate for capturing a video, and / or a resolution for capturing a video, and / or a time for capturing a video, and / or a sound for capturing a video, and / or a coding format for capturing a video, and / or a post-processing adjustment operation for the captured video;

[0076] In a specific embodiment, it also includes instructions for obtaining audio, and the instructions for obtaining audio include: obtaining the time range of the audio, and / or obtaining the volume value of the audio, and / or obtaining the encoding format of the audio, and / or post-adjustment operations on the obtained audio.

[0077] In actual applications, the user can set various parameters in the preset processing instructions in advance, so that when the output device 3 such as a display presents the picture in real time, the user can quickly capture the video or take a screenshot with one click.

[0078] In some specific embodiments, Figure 3 As shown, it also includes:

[0079] S601, performing content recognition on the second video stream by using an AI model for image recognition;

[0080] S602: If the current picture of the second video stream meets the preset requirements, a screenshot or video capture processing is performed on the current picture, and the content obtained by the screenshot or video capture processing is used as the processed content to perform the operation of "storing the processed content".

[0081] In actual applications, by using an AI model for image recognition to identify the content of the second video stream, the user can preset the image screen that he wants to obtain in advance, such as pre-setting the acquisition record page for the game screen or taking screenshots or video captures of the screen when a specific game character appears. By performing content recognition on the second video stream and automatically extracting the content that meets the preset requirements, it can effectively help the user to perform preliminary screening and storage of the screen, avoiding the user from forgetting to issue the preset processing instructions during the game or live broadcast. By automatically capturing the screen preset by the user, the user can obtain a preliminary rough cut screen after the entire game or live broadcast ends. Compared with the user manually issuing screenshot or recording instructions, by using the AI ​​model to match the user's preset parameters, the efficiency of the video or screenshot finally obtained by the user can be greatly improved.

[0082] In some specific embodiments, in step S400, after receiving the preset processing instruction, the method further includes:

[0083] S410, sending prompt information to the terminal 4, and / or the output device 3, and / or the operating device 5; the prompt information includes a graphical interface and / or prompt sound information.

[0084] In a specific embodiment, when the user sends a preset processing instruction to the loop-out collector 1 through the operating device 5, a relevant graphical interface may pop up on the display screen included in the output device 3 to prompt the user that the loop-out collector 1 has started or ended recording the picture content currently viewed by the user on the display screen.

[0085] In some specific embodiments, step S400 includes:

[0086] S401, reading the processed content of the preset time period before the current one according to the preset calling instruction, and sending the read processed content to the terminal 4; or

[0087] S402 , controlling the display of the stored processed content on the output device 3 , determining the processed content selected based on the preset calling instruction, and sending the determined processed content to the terminal 4 .

[0088] In some specific embodiments, Figure 4 As shown, before "receiving the preset call instruction", it also includes:

[0089] S001, sending a matching requirement to the loop-out collector 1 through the terminal 4 to match the terminal 4 with the loop-out collector 1;

[0090] S002. When there are multiple terminals 4, obtain the preset priority of each terminal 4, and adjust the order of sending the determined processed content to the terminal 4 according to the priority; or adjust the authority of the terminal 4 to receive the content according to the corresponding priority of the terminal 4.

[0091] In actual applications, when there are multiple terminals 4, by setting the priority of each terminal 4, and each priority may correspond to a permission to receive content, it is possible to achieve that while the output device 3 continuously outputs the video signal, the user can simultaneously intercept specific videos or pictures in the output device by operating the operating device 5, and simultaneously send them to multiple terminals 4. At the same time, by setting different permissions for receiving content for each terminal 4, in actual applications, various scenarios in applications such as live broadcasting and the needs of multi-person collaboration in video broadcasting and recording requirements can be effectively adapted.

[0092] This embodiment proposes a video acquisition method, which is applied to a loop-out collector, which is connected to a video source device, an output device and a terminal; the method includes: obtaining at least one source video signal from a video source device, processing the source video signal to obtain a first video stream, and simultaneously copying the first video stream to obtain a second video stream; sending the first video stream to the output device. Furthermore, the second video stream can be processed according to a preset processing instruction to obtain processed content, and the processed content can be stored; according to a preset call instruction, part or all of the processed content can be read and sent to the terminal. It can enable the user to intercept specific pictures or videos when the output device continuously outputs the picture, and this interception operation does not affect the output speed of the output device, which can effectively meet the user's needs for live game broadcast, live screen broadcast or game process preservation.

[0105] and / or for matching the first output unit 12 with the output device 3;

[0106] And / or used to match the second output unit 15 with the terminal 4.

[0107] It should be noted that the present embodiment does not specifically limit the specific number of output devices 3 and terminals 4.

When there are multiple output devices 3 and multiple terminals 4, the first output unit 12 can be matched with each output device 3, and the second output unit 15 can be matched with each terminal 4 through a matching unit.
