Problems solved by technology

[0005] In trying to solve the problem of high playback delay caused by user video operations, the centralized C / S structure leads to excessive load on the server and becomes the bottleneck of system scalability and robustness
The simple collection and storage of operation tracks accumulated by user video logs not only increases the complexity of the video log analysis model, but also causes a waste of storage space

Embodiment 1

[0065] see figure 1 , the present embodiment provides a method for storing video logs, specifically as follows:

[0066] Step 110: In the distributed hash table DHT network, the first strong node receives the video logs uploaded by ordinary nodes;

[0067] Step 120: The first strong node searches for a second strong node storing the video log by using a hash rule according to the identifier of the video log, and sends the video log to the second strong node;

[0068] Step 130: The second strong node extracts the time series from the video log, and according to the time series corresponding to the video log stored by itself and the set of the extracted time series, determine the corresponding The collection of new time series;

[0069] Step 140: Determine the popularity information of the video corresponding to the video log according to the new time series set.

[0070] The beneficial effects brought by the technical solution provided in this embodiment are:

[0071] In th...

Embodiment 2

[0073] figure 2 It is a system architecture for storing video corresponding to the embodiment of the present invention:

[0074] DHT (Distributed Hash Table, Distributed Hash Table) network based on Chord (a regular p2p network protocol) structure composed of strong nodes with relatively high performance and stability in the mobile network:

[0075] Specifically, the strong nodes in this embodiment can be servers, base stations, mobile terminals, etc., which have a relatively wide coverage and are relatively stable. The main functions of the strong nodes are to determine video popularity information, search for video popularity information, save Video logs and sending video popularity information to ordinary nodes, while providing access services for ordinary nodes, receiving video logs sent by ordinary nodes connected to it, periodically analyzing video logs and evaluating video popularity information, and publishing video log analysis results to others A strong node in the...

Embodiment 3

[0161] Figure 8 As shown, this embodiment provides a system for storing video logs, and the system is used to implement the methods for storing video logs provided in Embodiments 1 and 2 above. The system for storing video logs specifically includes: a first strong node 310, a second strong node 320;

[0162] The first strong node 310 includes: a receiving module 311 and a sending module 312;

[0163] The receiving module 311 is used to receive the video logs uploaded by ordinary nodes in the distributed hash table DHT network, use hash rules to find the second strongest node storing the video logs, and send the video logs to the the second strongest node;

[0164] The sending module 312 is configured to use a hash rule to search for a second strong node that stores the video log according to the identifier of the video log, and send the video log to the second strong node;

[0165] The second strong point 320 includes: a processing module 321 and a determination module 32...

Abstract

The invention discloses a method and a system for storing video logs, which belong to the communication field. The method comprises the following steps: in a distributed hash table (DHT) network, a first strong node receives a video log uploaded by a common node; the first strong node searches a second strong node storing the video log by using a hashing rule according to an identifier of the video log, and sends the video log to the second strong node; the second strong node extracts a time sequence from the video log, determines a set of new time-sequence corresponding to the video log stored in the second strong node according to a set of time-sequence corresponding to the video log stored in the second strong node and the extracted time sequence, and determines the video heat information corresponding to the video log according to the set of new time-sequence. According to the technical scheme, video logs can be subjected to distributed storage, and similar video logs can be merged, thereby reducing the storage pressure, facilitating the smooth watching of videos under video operation.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for storing video logs. Background technique [0002] With the popularization of mobile communication technology and the gradual increase of mobile bandwidth, large-scale video on demand (Video on Demand, VoD) services in the mobile environment are becoming a fast-growing service on the mobile Internet. The current VoD system mainly uses client / server (Client / Server, C / S) structure stores video from the server or uses MP2P (Mobile Peer-to-Peer Network, mobile point-to-point) wireless distributed network to store video. When acquiring videos, in addition to playing videos sequentially, most users also perform video operations, such operations include play, pause, fast-forward, and random jumps; some of these operations require jumpy access to video data Acquisition has brought problems such as high playback delay, which seriously affects the user experience. It is n...
