Problems solved by technology

[0003] The traditional method of screen recording and broadcasting is to collect signals through physical video cables, such as VGA cables, HDMI cables, DVI cables, etc. After the screen signals are collected, it is necessary to manually switch between broadcasting and broadcasting, that is, a special person will guard to judge whether It is necessary to switch the screen image to the live broadcast and recording operation. Due to the uncertainty of character activities in the scene and the rapid change of the scene, it is easy to make misoperations, such as missed cuts, wrong cuts, etc., during manual recording operations. If the situation is accurate, it will lead to the loss of wonderful shots in the captured video, which will increase the manual investment. Therefore, manual video editing work in the later stage is also required, which is also very time-consuming and labor-intensive. The missed highlights cannot be made up.

Embodiment 1

[0037] Example 1: Switching of director based on image recognition technology

[0038] 1) By playing the video on the computer system, the frame difference method used by the image recognition unit compares and analyzes the continuous picture frames in the virtual signal sent by the graphics card, determines that there are moving objects in the scene, and performs data on the screen connected to the graphics card Collect and send to the integrated data package;

[0039] 2) By opening the PPT on the computer system, the frame difference method used by the image recognition unit compares and analyzes the continuous picture frames in the virtual signal sent by the graphics card, determines that there are moving objects in the scene, and performs data on the screen connected to the graphics card Collect and send to the integrated data package;

[0040] 3) By opening the picture on the computer system, the frame difference method used by the image recognition unit compares and analyzes t...

Embodiment 2

[0041] Example 2: Switching the director based on keyboard and mouse hook detection technology

[0042] 1) By clicking the mouse, when the computer system processes the mouse system code segment, add a jump instruction before the mouse use instruction, and transfer to the custom instruction for continuous screen capture of the operating system screen, and perform the operation on the screen connected to the graphics card. Data is collected and sent to the integrated data package.

[0043] 2) By pressing the keyboard, when the computer system processes the keyboard system code segment, add a jump instruction before the keyboard use instruction, and transfer to the custom instruction for continuous screen capture of the screen of the operating system. Perform data collection and send it to the integrated data package.

Embodiment 3

[0044] Example 3: Switching of directors based on USB signal detection technology

[0045] According to the insertion and removal of the device, after inserting the USB interface of the laser pointer, the computer system recognizes successfully. When there is a hardware change, the operating system will send a message to notify the program. After the program receives the system notification, it can continue to use hook technology Intercept the communication message of the USB device, and then process the laser pen code segment through the computer system, add a jump instruction before the use instruction of the laser pen, and transfer to the custom instruction for continuous screen capture of the operating system screen, and connect the graphics card The screen performs data collection and sends it to the integrated data package.

Abstract

An intelligent screen capture system for automatically detecting user behaviors is disclosed. By using the image recognition and analysis technology developed by a computer program, a Keyboard and mouse hook detection technology and a USB signal detection technology, and through the comprehensive application of various technologies, a more complete system user behavior detection technology is developed, the user detection is realized at a collection end, and through the network signals, the judgment results of the user behaviors are transmitted to the recording and broadcasting system, therebyreducing the CPU computing resource consumption of the recording and broadcasting system. At the same time, the information collection of user's computer screen is realized by a streaming media technology, and the traditional method of physical video line collection is abandoned.

Description

Technical field [0001] The invention relates to a recording and broadcasting system, in particular to an intelligent screen capture system for automatic detection of user behavior. Background technique [0002] In recent years, the application of recording and broadcasting systems has become more and more extensive, and the demand for on-site real-time recording, live broadcasting, and post-on-demand broadcasting of activities in various industries has grown rapidly. The recorded video files are used for recording, learning, and sharing. Especially in schools and education and training industries, the construction of high-quality video resources is the key direction of school education informatization, such as video recording of video resources such as excellent lessons, micro lessons, and quality courses. Therefore, it is a very urgent desire of all walks of life to simply generate a video course resource with high viewing and good effects. However, the current product applicat...
