Method for downloading videos during roaming in micro-video and peer-to-peer network-based virtual network map

Abstract

The invention relates to a method for downloading videos during roaming in a micro-video and peer-to-peer network-based virtual network map. The method comprises the following main steps of: dividing a virtual video which is in synchrony with a map into micro videos section by section for providing convenience for loading each small section of video and compensating redundancy; converting each client into a peer-to-peer body to ensure that all clients and servers form a peer-to-peer network and a peer-to-peer (P2P) retrieval technology-based video index and a video buffer are set on each peer-to-peer body; when a user starts virtual roaming, periodically determining a neighborhood path range according to the current roaming position; sending a retrieval request to a peer-to-peer (P2P) video index system according to a micro-video set required in the neighborhood path range; downloading the required micro-videos from a plurality of peer-to-peer bodies by mature multi-point downloading technology according to a retrieval result, and after the downloading is finished, inserting the micro-videos into a local video buffer and updating the video index of the peer-to-peer network; and when the user finishes the virtual roaming, stopping a timer.

Description

Technical field [0001] The invention belongs to the field of computer technology. In particular, it relates to a method for downloading multimedia information from a computer, and more particularly to a method for downloading videos during roaming of real-world network maps based on micro-video and peer-to-peer networks. Background technique [0002] With the rapid development of multimedia technology and network map technology, real-world network map technology has become an important direction for future network map development. The real scene network map technology can not only provide traditional electronic map functions such as place name search and route navigation, but also provide route synchronization real scene video for route navigation, which greatly improves the user's sense of presence and navigation experience. [0003] In order to support distributed processing and arbitrary line query operations, the discrete mathematical structure "map" is an ideal storage method...

AI Technical Summary

Problems solved by technology

[0004] However, since the user needs to play video synchronized with the road in real time when roaming in the real scene, it is necessary to download a large number of videos required for real-time roaming in real time or in advance

Due to the large amount of video information, when the user scale is relatively large, a large number of video download requests to the server will greatly increase the load on the server, resulting in server bandwidth congestion and increasing bandwidth costs in operation

Or, when the bandwidth and computing resources are insufficient, the playback of the user's real-life video will be interrupted, which will affect the quality of experience of the user's real-life roaming

[0005] In view of the above problems, the present invention proposes a video downloading method in real-scene network map roaming based on micro-video and peer-to-peer network to solve the problems of efficiency, bandwidth, stability and reliability of large-scale real-scene network map real-scene video download
