Embodiment Construction

[0032] In the following description with reference to the embodiments, the embodiment of the present invention proposes a peer-to-peer media transmission system, which indexes part of the content cached on the hard disk of the client by organizing user nodes into a specific network structure.

[0033] In this embodiment, the received and acquired media data content is buffered in the form of content blocks, and the media data is divided into blocks and stored in the form of blocks, and the media data includes video frames and audio frames. In this embodiment, video files are taken as an example. Generally, video files can be simply divided into content metadata and actual media data. Metadata includes overall information and time positioning information of the entire media file, while media data mainly refers to data of specific video frames and audio frames. For example, in the asf file format, the Header Object (the overall information of the file) in the file header and the...

Abstract

The embodiment of the invention discloses a method for caching content. The method comprises the following steps: caching the obtained media data content in a content blocking manner; clustering normal user nodes according to the content; choosing one or more management nodes to manage the clusters of normal user nodes, which cache the same content; and recording the address information of each node in the clusters, and the blocking information owning the content. At the same time, the embodiment of the invention further provides a method for searching the content, a point-to-point media transmission system, and management nodes. The embodiment of the invention enables the normal user nodes to conveniently and efficiently utilize the content stored by other users, improves the searching accuracy and efficiency by a user, overcomes the defect in the prior art that the searing efficiency is low, and reduces the burden of a server.

Description

technical field [0001] The invention relates to a point-to-point media transmission technology, in particular, a content cache and search method and a point-to-point media transmission system are designed. Background technique [0002] Video on demand refers to the business of providing interactive video services at any time according to the needs of users. In actual systems, due to the limitation of system capacity, service providers generally provide a certain number of video programs in advance, and then users can choose them at any time. One of the programs can be watched, and the on-demand system can also provide functions such as pause, fast forward and fast rewind, so as to facilitate users to watch. Video-on-demand technology has also become the focus of research and development in the industry. [0003] There are two solutions for traditional video on demand: one is that users only record data in the memory when watching, and adopt a policy of discarding the part t...
