Embodiment Construction
[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0038] figure 1 It is a schematic structural diagram of an acceleration system for network video loading according to an embodiment of the present invention. In this embodiment, the system for accelerating network video loading includes a client 100 , an acceleration device 200 and a video server 300 . The client 100 is communicatively connected to the acceleration device 200 through a wired and / or wireless link, and the acceleration device 200 and the video server 300 perform video communication through a communication network (for example, the Internet).
[0039] The client 100 may be various t...

The invention discloses an acceleration method, equipment and system for network video loading. The method comprises the following steps: S1, receiving video request information from a client and sending the video request information to a video server; S2, receiving the video data stream of the required video from the video server; S3, after receiving a size-predetermined video fragment, calculating the identification code of the required video according to the video fragment, wherein the identification code can uniquely identify the video; and S4, searching a cached video according to the identification code, stopping receiving the video data stream from the video server if finding the video data matched with the identification code, and sending the found video data to the client, if notfinding the video data matched with the identification code, continuing to receive the video data stream from the video server, caching the received video data, and sending the video data to the client. According to the invention, network bandwidth is saved, and video loading speed is accelerated.
Description
technical field [0001] The invention relates to network video-on-demand technology, in particular to an acceleration method, device and system for network video loading. Background technique [0002] With the development of Internet technology, people have higher and higher requirements for the response speed of web pages, especially when online video on demand, it is hoped that the video loading speed should be as fast as possible. In the prior art, a Web cache acceleration method is generally adopted to accelerate video loading. Web cache acceleration refers to caching the response data to the cache server after the first request to a certain webpage is completed on the intranet. When other users on the intranet access the same external network resource, the cache server sends the data directly to the request. , so there is no need to request and download the resource from the Internet again. In the prior art, Web cache acceleration is generally calculated by calculating...
