Problems solved by technology

[0004] In the video cloud storage system, the video cloud storage server, camera equipment, and client may be located in different regions. Since the video cloud storage server determines the time of the video based on UTC (Universal Time Coordinated, Universal Time Coordinated Time), the camera equipment and client The end determines the time of the video based on the local time of the camera device. When the area where the camera device is located enters daylight saving time, when the video cloud storage server acquires and stores the video data uploaded by the camera device, the acquired video data may be different from the actual one. Inconsistencies in the video data of the required time period; when the client queries or downloads a video of a certain period of time stored in the video cloud storage server, the video obtained by querying or downloading may not match the video of the expected time period

Embodiment 1

[0118] In order to solve the above problems, such as figure 2 As shown, the embodiment of the present invention provides a video data storage method, which can be applied to video cloud storage servers, and of course can also be applied to other types of devices with data processing and computing functions. The process may include the following steps:

[0119] S101. Obtain a preset storage start time corresponding to the imaging device to be requested.

[0120] In the embodiment of the present invention, the preset storage start time may be the time at which the video cloud storage server corresponding to the recording start time in the recording plan is located. The recording start time and end time in the recording plan can be set based on the time of the region where the corresponding camera equipment to be requested is located. For example, 8:00-9:00 is set as the recording start time and end time, where The 8:00 and 9:00 of the request can refer to the time in the regio...

Embodiment 2

[0158] Such as Image 6 As shown, the embodiment of the present invention also provides a video data storage method, the method process specifically includes:

[0159] S201. The video cloud storage server acquires a preset storage start time corresponding to the camera device to be requested.

[0160] In the embodiment of the present invention, the preset storage start time may be the time at which the video cloud storage server corresponding to the recording start time in the recording plan is located, wherein the recording start time in the recording plan may be set by the user in the client After setting, it is sent to the video cloud storage server, so the video cloud storage server can easily obtain the above-mentioned preset storage start time.

[0161] The video cloud storage server can be connected with multiple cameras. The camera device to be requested may be the object to which the video cloud storage server will send a video data storage request, and the camera d...

Embodiment 3

[0181] In order to solve the above problems, such as Figure 7 As shown, the embodiment of the present invention provides a video data request method, which can be applied to the client, and of course can also be applied to other types of devices with data processing and computing functions. The process may include the following steps:

[0182] S301. Obtain the start time and end time of the video to be requested.

[0183] In the embodiment of the present invention, the start time and end time of the video to be requested can be obtained through the client.

[0184] When the camera device shoots a video, it usually stamps a time stamp on the video (that is, superimposes the time OSD on the video image), so that it is convenient for the user to view it in the future. If the user wants to obtain a certain video, it is usually determined based on the time stamp information in the video. The start and end times of the video. Therefore, the user can input the start time and end t...

Abstract

An embodiment of the present invention provides a video data storage method, a request method, a storage device, and a request device, wherein the video data storage method includes: obtaining the preset storage start time corresponding to the camera equipment to be requested; judging the preset storage start time Whether it is during the daylight saving time of the area where the camera equipment to be requested is located, if it is not during the daylight saving time, when it is determined that the storage start time is reached, send a video data storage request to the camera equipment to be requested; if it is during the daylight saving time, calculate The daylight saving time request time corresponding to the storage start time is preset, and when it is determined that the daylight saving time request time is reached, a video data storage request is sent to the camera device to be requested; the video data uploaded by the camera device to be requested is received and stored. The embodiments of the present invention can ensure that the video data stored by the video cloud storage server is consistent with the video data in the actual required acquisition time period.

Description

technical field [0001] The invention relates to the technical field of video cloud storage, in particular to a video data storage method, a request method, a storage device, and a request device. Background technique [0002] Video cloud storage technology is a technology that provides video cloud storage and query, and has been more and more widely used in the security monitoring industry. A video cloud storage system usually includes a video cloud storage server, a camera device, and a client. The video cloud storage server can receive and store the video captured by the camera device through the network, and the client can also obtain the video stored in the video cloud storage server through the network. video. [0003] Daylight saving time is a system that artificially regulates local time in order to save energy. When the local time of a country or region enters a certain moment, the local time will be artificially adjusted forward by 1 hour, for example, when the lo...
