Description

Technical Field

[0001] The present invention relates to the field of multimedia technology, and in particular to a multimedia recording and saving method with multi-threading and precise positioning points. Background Art

[0002] Existing multimedia recording and saving methods generally adopt continuous whole-segment recording and saving, or time-fixed segmented recording and saving. The disadvantages of this method are that when you need to find a specific segment of multimedia, you need to spend a lot of energy and time to check from beginning to end before you can select and save it. Another disadvantage is that when the storage space is insufficient, the previous content will be continuously cyclically overwritten. However, a large amount of the recorded content is invalid content, that is, a large amount of invalid content will overwrite the valid content. This makes the recording and saving of multimedia very inconvenient to use.

[0003] Currently, for the multimedia recording and saving methods on the market, due to insufficient threads embedded in the circuit board or inaccurate positioning of recording and saving, a large amount of the recorded content is invalid content, that is, a large amount of invalid content will overwrite the valid content, and the effect of precise recording and saving of multimedia cannot be achieved.

[0004] Therefore, it is necessary to develop a multimedia recording and saving method with multi-threading and precise positioning points. Summary of the Invention

[0005] The present invention provides a multimedia recording and saving method with multi-threading and precise positioning points. Multiple threads are developed using an embedded circuit board. One thread is used to maintain continuous or intermittent recording of multimedia, and another thread or multiple threads are responsible for monitoring whether there is a trigger signal, solving the problem of a multimedia recording and saving method with precise positioning points.

[0006] To solve the above problems, the present invention provides a multimedia recording and saving method with multi-threading and precise positioning points, including multimedia and an embedded circuit board, and the embedded circuit board is provided with multiple threads;

[0007] The steps of the multimedia recording and saving method with multi-threading and precise positioning points are as follows:

[0008] S01. Use the embedded circuit board to support the access of multimedia;

[0009] S02. Develop multiple threads in the embedded system of the embedded circuit board: Thread A, Thread B, Thread C... Thread N, etc.;

[0010] S03. Thread A is responsible for long-term recording and saving of multimedia and will not be interrupted or interfered by the other Thread N, and the other Thread N are also independent of each other and do not interfere with each other;

[0011] Thread S04 and the thread N respectively monitor their respective trigger signals. When the corresponding trigger signal occurs, the thread will start.

[0012] S05. The trigger condition of the thread B is the button B. When there is no trigger signal, B = 1; when there is a trigger signal, B = 0. The save duration set by the user is TB. The duration direction F set by the user has three types: increasing the duration forward, F = FQ; increasing the duration backward, F = FH; increasing the duration both forward and backward, F = FQH. The demand signal ZD indicating whether to send to the terminal set by the user: when it is necessary to send, ZD = 0; when it is not necessary to send, ZD = 1.

[0013] S06. When the button B is pressed, B = 0, and the time at the moment when the button B is pressed is T0. The thread B will save the video starting from T0. According to the duration direction F:

[0014] (1) When F = FQ, the thread B saves the video to the specified location. The start time of this segment of the video is T0 - TB, and the end time is at T0. And the file name of this video is named after the time of the time point T0, XXXX year xx month xx day xx hour XX minute XX second; check ZD, if ZD = 0, send this video to the terminal, if ZD = 1, do not need to send this video, and the thread B re - enters the monitoring state.

[0015] (2) When F = FH, the thread B saves the video to the specified location. The start time of this segment of the video is T0, and the end time is at T0 + TB. And the file name of this video is named after the time of the time point T0, XXXX year xx month xx day xx hour XX minute XX second; check ZD, if ZD = 0, send this video to the terminal, if ZD = 1, do not need to send this video, and the thread B re - enters the monitoring state.

[0016] (3) When F = FQH, the thread B saves the video to the specified location. The start time of this segment of the video is T0 - TB, and the end time is at T0 + TB. And the file name of this video is named after the time of the time point T0, XXXX year xx month xx day xx hour XX minute XX second; check ZD, if ZD = 0, send this video to the terminal, if ZD = 1, do not need to send this video, and the thread B re - enters the monitoring state.

[0017] S07. When the thread N is triggered, the process of S06 is also repeated, without interference with each other.

[0018] S08. One thread Z in the other threads N is responsible for recording the time points of all the triggered other threads N within the recording period of all the threads A, for the user to customize the video capture.

[0019] A further solution is that the triggering conditions of the thread include methods such as physical buttons, screen touch control, voice control, digital instruction methods, etc.

[0020] A further solution is that the saved terminals include, but are not limited to, computers, mobile phones, tablets, servers, cloud, third-party software and platforms, etc.

[0021] A further solution is that the multimedia includes videos, audios, animations, pictures, texts, data, etc.

[0022] The beneficial effects of the present invention are as follows: The multi-threaded multimedia recording and saving method with precise positioning of the present invention designs a multi-threaded system through the embedded system of the embedded circuit board. One thread is used to maintain continuous or intermittent recording of multimedia, and another thread or multiple threads are responsible for monitoring whether there is a trigger signal. When a trigger signal is detected, this thread will automatically save the multimedia to another storage area. The time of the saved multimedia is from the signal trigger time forward or backward and maintains a certain duration; and the file name is named according to the trigger time, and at the same time, it supports saving the video to a specified terminal through network transmission.

[0037] S07. When other thread Ns are triggered, they also repeat the process of S06 without interfering with each other.

[0038] Thread Z in another thread N, namely S08, is responsible for recording the time points of all triggered other threads N during the period when all threads A are recorded, for the user to customize video capture.
