So far, the description of the system architecture shown in fig. 1 is completed.

Based on the system architecture illustrated in fig. 1, the following describes a video playback method illustrated in fig. 2.

Referring to fig. 2, a flowchart of an embodiment of a video playback method according to an exemplary embodiment of the present application is provided. In one example, the method may be applied to the client 11 described above.

As shown in fig. 2, the process may include the following steps:

step 201: and determining a target time point and a video playback mode to be subjected to video playback.

As an embodiment, the video playback mode may be set by the user according to actual service requirements. In one example, the video recording/playback mode is a mode in which video recording is played back in accordance with a target time zone, and the target time zone is a time zone corresponding to the target time zone.

In one example, the target time zone may be a time zone in which the client 11 is located (hereinafter referred to as a client time zone), and in this case, the recording/playback mode may be a mode in which recording is played back in accordance with the client time zone.

In another example, the target time zone may be a time zone (hereinafter referred to as a first time zone) in which a video recording device (hereinafter referred to as a designated video recording device) designated in the system architecture shown in fig. 1 is located. As an embodiment, the specified video recording device may be a video recording device selected by a user according to actual needs. In the case where the target time zone is the first time zone, the recording/playback mode may be a mode in which recording is played back in accordance with the first time zone. It should be noted that, the specified video recording device may be switched subsequently according to actual service requirements.

Step 202: and determining a target playing time point for playing back the video for the target video recording equipment to be subjected to video playback according to the target time zone and the target time point, and playing back the video in the target video recording equipment according to the target playing time point determined for the target video recording equipment.

As an embodiment, here, playing back the video in the target video recording device according to the target play time point determined for the target video recording device may include: and respectively sending the target playing time points determined for the target video recording devices to the target video recording devices, so that the target video recording devices find corresponding videos from all the stored videos according to the received target playing time points and send the corresponding videos to the client 11, and the videos in the target video recording devices are synchronously played back through the client 11.

In an embodiment, when the video playback mode is a mode for performing playback video according to a client time zone, if the number of target video devices to be subjected to video playback is greater than 1, the target playing time points of the target video devices are the same, so as to achieve synchronous playback of the monitoring pictures of the target video devices at the same time of the client. The target playing time point may be a reference time point convenient for each target video device to identify, and the following embodiment 1 describes an example.

In another embodiment, when the video playback mode is a mode in which video is played back according to the first time zone, if the number of target video devices to be subjected to video playback is greater than 1, the target playing time points of the target video devices are different, but the corresponding time information of the target playing time points of the target video devices in the time zone in which the target video devices are located is the same, so as to implement synchronous playback of the monitoring pictures of which the local times of the target video devices are the same. Example 2 is described below by way of example.

Thus, the flow shown in fig. 2 is completed.

As can be seen from the flow shown in fig. 2, under the condition of video playback to be performed, a target playing time point for playing back a video is specifically determined for a target video device to be subjected to video playback according to a target time point to be subjected to video playback and a target time zone corresponding to the target time point (a video playback mode performs playback video according to the target time zone), and then videos in the target video devices can be played back according to the target playing time point determined for the target video device, so that video in the target video devices can be played back.

Further, in this embodiment, the target playing time point for playing back the video is determined for the target video recording device to be subjected to video playback according to the target time zone and the target time point, instead of blindly directly adopting the target time point as the target video recording device to determine the target playing time point for playing back the video, so that when the time zone corresponding to the target time point is different from the time zone in which the target video recording device is located, the target playing time point for playing back the video can be determined for the target video recording device based on the target time zone and the target time point, and the video in the target video recording device can be played back when the time zone corresponding to the target time point is different from the time zone in which the target video recording device is located.

Still further, when the number of the target video recording devices is greater than 1, even if the target video recording devices are distributed in different time zones, according to the video recording playback method, the video recordings in the target video recording devices distributed in different time zones can be played back synchronously.

Next, how to determine a target playing time point for playing back the recorded video for the target video recording device to be subjected to video recording playback according to the target time zone and the target time point in step 202 is described.

Referring to fig. 3, an implementation flow for determining a target playing time point in step 202 is provided for an exemplary embodiment of the present application. As shown in fig. 3, the process may include the following steps:

step 301: and converting the target time point in the target time zone into a reference time point in the set reference time zone according to the first time difference.

In one example, in a case where the target time point is not in daylight saving time of the target time zone, the first time difference may be determined according to a time zone offset between the target time zone and the reference time zone, for example, the first time difference may be a time zone offset between the target time zone and the reference time zone. As an example, the reference time zone may be a 0 time zone (also referred to as UTC time zone). Taking the reference time zone as 0 time zone (also called UTC +0) and the target time zone as the eighty-th zone (UTC + 8: 00), the first time difference is 8-0 to 8 hours.

In another example, in the case where the target time point is daylight saving time of the target time zone, the first time difference may be determined according to a time zone offset between the target time zone and the reference time zone, and the daylight saving time offset. For example, the first time difference is a result of adding a daylight saving time offset to a time zone offset between the target time zone and the reference time zone. As an example, the reference time zone may be a 0 time zone (also referred to as UTC time zone). Taking the reference time zone as 0 time zone (also called UTC +0), the target time zone as the eighty-th zone (UTC + 8: 00), and the daylight saving offset as 1 hour, the first time difference is 8+1 to 9 hours.

Based on the first time difference, the target time point in the target time zone may be converted into a reference time point in a set reference time zone according to the first time difference, which is described in embodiment 1 and embodiment 2 below by way of example, and details are not repeated here.

Step 302, determining a target playing time point for playing back the video for the target video device according to the reference time point.

In one example, any video recording device records the video recording time by using the reference time in the reference time zone, and based on this, in this step 302, determining the target playing time point for playing back the video for the target video recording device according to the reference time point may include: and directly determining the reference time point as a target playing time point of the target video equipment for playing back the video. In this way, when the reference time point determined for the target video recording device is sent to the target video recording device as the target playing time point of the target video recording device, the target video recording device directly finds the corresponding video from all the stored videos according to the received target playing time point and sends the corresponding video to the client 11, so as to realize synchronous playback of the videos in the target video recording devices through the client 11.

It should be noted that the above is only an example of determining the target playing time point, and is not limited. The target playing time point may also be determined according to the reference time point by other manners, for example, a result obtained by adding a specified time point to the reference time point is the target playing time point, and the like, which are not illustrated in this embodiment.

The flow shown in fig. 3 is completed.

Through the process shown in fig. 3, it may be finally achieved that the target playing time point for playing back the video is determined for the target video recording device to be subjected to video playback according to the target time zone and the target time point.

The flow shown in fig. 3 is described below by two examples:
