A data caching method and system for online multimedia information mining

Abstract

The invention discloses an online multimedia information mining oriented data caching method and system. The method comprises the following steps of: distributing a cache pool for the online multimedia information in an internal memory, wherein the cache pool is composed of pre-set receiving buffers with different lengths; applying for corresponding buffers to store multimedia data according to length attribute information of the captured online multimedia information; establishing a received data information chain table for the captured online multimedia information, and recording the received multimedia information in a form of orderly chain table; and inquiring the received data information chain table, and storing the multimedia data in the buffers.

Description

technical field [0001] The invention relates to the technical field of Internet information mining, in particular to a data cache method and system for online multimedia information mining. Background technique [0002] Multimedia information has the characteristics of huge data volume, multiple data types, large gaps between data types, and complex input and output. Traditional data is represented by encoding, and the amount of data is not large. However, the amount of multimedia data is huge. For example, a color photo with a resolution of 640×480 and 256 colors requires 0.3MB of storage; a CD-quality two-channel sound requires 1.4MB per second of storage. Multimedia data includes various forms such as graphics, images, sounds, texts, and animations. Even if they belong to the same category of images, they can also be divided into black and white, color, high-resolution, and low-resolution. The large gap between data types is mainly manifested in: the storage capacity of...

Problems solved by technology

Although this method is effective, there are three obvious defects: one is that it can only mine the existing collection of Internet multimedia information, and cannot reflect the updated multimedia information on the Internet in time; Third, all multimedia information comes from active access, which cannot reflect the characteristics of multimedia information actually transmitted online

For the mining of online multimedia information, these defects do not exist at all. It provides the source information of information mining by capturing the multimedia information actually transmitted online on the backbone data interface. The fundamental reason why this method has not been widely used is that it requires The amount of captured data is huge, the data is complex and diverse, and the multimedia data is highly concurrent, making it difficult to perform high-speed and effective cache management

[0004] The hard disk cache solution for personal user data download is limited by the lifespan and bandwidth of the hard disk, and cannot meet the data cache management in this application background
