Embodiment Construction
[0069] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0070] see figure 1 , figure 1 is a flowchart of the present invention.
[0071] A sharing method based on similar playback mode extraction in a wireless video sharing system. The wireless video sharing system includes a video server and several nodes connected to the video server. The video server stores all video resources in the video system and provides video data for the nodes. The sharing method includes S1 to S5.
[0072] S1. The video server changes...

The invention discloses a sharing method based on similar playing mode extraction in a wireless video sharing system. The method comprises the following steps: S1, a video server changes the interestdegree of a behavior sensing node of a video playing point in video content according to a node; S2, the video server extracts a plurality of playing modes according to the interest degrees of all thenodes on the same video content, and clusters all the nodes according to the playing modes to obtain a plurality of node subsets; S3, the video server designates a head node in each node subset, thehead node is responsible for maintaining state change behaviors and resource cache information of other nodes in the node subset to which the head node belongs, and all the head nodes jointly maintainvideo sharing behaviors among all the nodes; S4, the video server maintains a new node to join the system or the node exits the system; And S5, the video server senses the behavior that the new nodeactively changes the subsets of the nodes to which the new node belongs. The efficiency of sharing video resources among the nodes can be effectively improved, and the user experience is improved.
Description
technical field [0001] The invention relates to the technical field of video resource sharing, in particular to a sharing method based on similar playback mode extraction in a wireless video sharing system. Background technique [0002] It is of great significance to provide video services for users holding smart handheld devices in wireless networks so that they can watch video content anytime and anywhere. According to Cisco's forecast, by 2020, video data traffic will account for two-thirds of global mobile traffic. This is because video services can provide users with rich visual content, thereby attracting a large number of video users and generating extremely large-scale video traffic. As of December 2017, the number of online video users in China has reached 579 million, and the usage frequency has reached 75%. The deployment of large-scale video systems will inevitably face the problems of service quality and scalability. When the number of users included in the v...
