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...

A sharing method based on similar playback mode extraction in a wireless video sharing system, including: S1. The video server changes the behavior of the video playback point according to the node to perceive the degree of interest of the node in the video content; S2. The video server bases the interest of all nodes on the same video content. Extract several playback modes to a certain extent, and cluster all nodes according to the playback mode to obtain several node sub-sets; S3, the video server specifies a head node in each node sub-set, and the head node is responsible for maintaining the node sub-set to which it belongs The status change behavior and resource cache information of other nodes in the network, all head nodes jointly maintain the video sharing behavior between all nodes; S4, the video server maintains the new node joining the system or the node exiting the system; S5, the video server perceives that the new node actively changes the belonging The behavior of the node sub-collection. The present invention can effectively improve the efficiency of sharing video resources between nodes and improve user experience.
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...
