Problems solved by technology
In actual operation, recording tasks can be divided into manual, timing, alarm and other types. If the same channel is recording and adding other types of recording tasks, it is necessary to stop the previous recording task according to the conventional method, and then start a new recording task. The more such cases, the more video interruptions, the more fragmented video files will be generated, and there will be a certain time difference in the processing process, which will lead to problems such as loss of video recording time points, and further cause the previous video task to be premature. At the end, the video recording time and settings are inconsistent
This situation not only greatly reduces the customer experience, but also may cause the user to lose key time points due to the discontinuity of the video recording, causing serious impact or even loss on the customer

Embodiment Construction
[0041]The main idea of the present invention is that when the channel in the recording task table has existing recording tasks of different types at this time, the code stream of the recording tasks is compared, and the existing recording tasks are alarm recording tasks. If the code stream of the existing recording task is the same, then compare whether the current recording task and the existing recording task have overlapping recording time periods. If there is overlap, it is considered that overlapping is required, and the overlapping processing is performed; if the existing recording task is a scheduled recording task or a manual recording task, the It is necessary to further judge whether the generation of the current video recording task is legal, and when it is further judged that the generation of the current video recording task is legal, superposition processing is performed.
[0042] The superposition processing is to compare the start time point of the current tas...

The invention discloses a superposition processing method and a device of video recording tasks in video monitoring. The method comprises inserting generated current video recording tasks into a video recording task list, comparing the code streams of the video recording tasks when the channel in the video recording task list has different types of existing video recording tasks at this time, comparing whether the video recording time period of the current video recording task and the video recording time period of the existing video recoding task are superposed when the code streams of the current video recording task and the existing video recording task are the same and the existing video recording task is alarming video recording, and carrying out superposition processing if superposed; comparing the start time point of the current video recording task, the start time point of the existing video recording task, the ending time point of the current video recording task and the ending time point of the existing video recording task, and carrying out superposition processing according to the comparison results. The invention avoids the problems of video recording file fragmentary caused by service complexity and operation diversity in the video recording process of the monitoring system, discontinuous video recording time period, and easy miss of video recording points.
Description
technical field [0001] The invention belongs to the technical field of video surveillance, and in particular relates to a processing method and device for merging and superimposing video recording tasks of multiple tasks, types and time periods in a video surveillance system. Background technique [0002] In recent years, video surveillance services have received extensive attention with the continuous development of network technology. This new value-added service of image remote transmission and management based on broadband network or mobile network is accepted by more and more users. The video surveillance business mainly provides users with services such as real-time video viewing, PTZ control operation, video storage management, and alarm linkage notification. Users can monitor monitoring points around the clock anytime, anywhere. [0003] With the continuous improvement of business and the increase of users, the stability and continuity of the system have become more...
