DETAILED DESCRIPTION

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] First, combine Figure 3 The embodiment of the present invention provides a distributed video playback system based on a B / S structure. The video playback system is based on a B / S structure (Browser / Server) and provides services to users through the Web. Figure 3 As shown, the system includes: a server 100, a video recording device 200 and a user terminal 300.

[0014] The user end 300 allows the user to view the video information and associated information on the server end 100 , and sends an access request for a target video to the server end 100 .

[0015] The video recording device 200 is used to send video information of the stored video to the server 100 , and to send the target video to the user end 300 .

[0016] Specifically, the video recording device 200 is composed of a series of devices, each of which stores a video. After recording a video, the recording device no longer uploads the video to the server 100, but stores the video by itself and uploads the video information of the video to the server 100. By uploading the video information to the server, the server 100 is notified that the video exists on the video recording device.

[0017] The user can enter the server address and access the server through the user terminal 300. The server 100 can establish an association relationship between each video information and the video recording device 200; and obtain the communication information of the target video recording device 200 corresponding to the target video based on the association relationship, and send an access request to the target video recording device, so that the target video recording device 200 can send the target video to the user terminal 300.

[0018] The client 300 allows the user to view the video information and associated information on the server 100, and sends an access request for a target video to the server 100. When the user accesses a video through the client 300, the server 100 returns the associated information and video information to the client 300 via the Web.

[0019] The server 100 may be a service device disposed on the network side. The server 100 exchanges data with the video recording device 200 and the user terminal 300 through the network. The server 100 may be implemented as a single server or as a server cluster consisting of multiple servers.

[0020] Next, combine Figure 2 The embodiment of the present invention introduces a distributed video playback method based on a B / S structure from the perspective of a server. Figure 2 As shown, including: Step S01: receiving video information of stored videos reported by each video recording device, and establishing an association relationship between each video information and the video recording device.

[0021] Specifically, after the video recording device 200 completes recording, it stores the recorded video by itself. The video recording system does not need to upload the video to the server 100, but only needs to upload the video information of the video to the server 100. The server 100 establishes a connection between the video information and the corresponding video recording device according to the video information of the video and the video recording device 300 to obtain an association relationship. The video information includes the video file name, device IP address, etc.

[0022] Examples include Figure 4 After the video recording device completes recording, it reports the video information of the corresponding videos Video1, Video2 and Video3 to the server. For example, a video Video 1 is stored on the video recording device. The video recording device sends the video information of Video 1 to the server through the interface to notify the server that Video1 is stored in the video recording device. The server 100 records the association between the video recording device and Video1 through a database or text file. The interface can be a network communication interface such as http, rpc, mqtt, etc.

[0023] The server 100 provides a Web server with a B / S architecture and a unified portal, and users access the server through the user terminal.

[0024] Step S02: obtaining an access request for a target video sent by a user terminal.

[0025] Specifically, when a user accesses a video through the client 300, the server 100 returns relevant information to the client 300 through the Web, wherein the information sent includes the associated information of the video information and the video recording device. Figure 4As shown, the client browses videos Video1, Video2 and Video3 through the server. The server 100 registers ServiceWorker through Javascript to intercept the access request of the client 300 to Video1, and forwards the access request to the video recording device through http or WebRtc.

[0026] Step S03: acquiring communication information of a target video recording device corresponding to the target video based on the association relationship.

[0027] Specifically, the javascript of the client 300 initiates a request to the server 100 to obtain communication information related to the target video recording device. If the server 100 and the target video recording device are in the same network segment, the IP address of the target video recording device may be returned, or the relevant information of the WebRtc communication between the client 300 and the target video recording device may be returned.

[0028] Step S04: sending an access request to a target video recording device, so that the target video recording device can send the target video to the user end.

[0029] Specifically, the server 100 intercepts the access request of the client 300 to play the target video file by using ServiceWorker in Web JS, and sends the access request to the target video recording device 300, which directly returns the video data to the Web of the client 300. After receiving the video data, the client 300 can directly render it through the client 300. The Web service or WebRtc service of the target recording device provides the actual video stream to the client.

[0030] The video playback method provided by the embodiment of the present invention makes the user feel that the video resources are all provided by a Web service with a unified B / S architecture, but the actual resources are distributed and stored on various video recording devices, and the acquisition of video resources is directly transmitted between the user end and the video recording device, which can effectively reduce the video bandwidth bottleneck of the server end and alleviate the bandwidth pressure of the system.

[0031] Furthermore, the distributed video playback method based on the B / S structure of the embodiment of the present invention may further include, before obtaining the access request of the target video sent by the user terminal in step S02: The stored video information and association relationships are displayed for users to view through the user terminal.

[0032] Specifically, the client 300 accesses the server 100, and the server 100 displays the video and displays the video information of the video. At the same time, the Http Response carries the associated information of the video and the video recording device. The distributed video playback method based on B / S structure provided by the embodiment of the present invention comprises the following steps: the server receives the video information of the stored videos reported by each video recording device, and establishes the association relationship between each video information and the video recording device; obtains the access request of the target video sent by the user end; obtains the communication information of the target video recording device corresponding to the target video based on the association relationship; and sends the access request to the target video recording device so that the target video recording device can send the target video to the user end. The videos in the present invention are distributedly stored in each video recording device, so the video traffic does not pass through the server end, which can save video traffic. When different users browse videos on different video recording devices, the traffic can be effectively diverted, and the preview service can be provided in a timely manner while saving bandwidth.

[0033] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
