The method for acquiring media comprises the following steps: receiving a media request message carrying media identification and playing time; acquiring general media description information corresponding to the media identification; searching the segmental identification corresponding to the playing time according to the general media description information; acquiring the segmental description information corresponding to the segmental identification; and receiving the segmental content corresponding to the segmental identification according to the segmental description information. The embodiment of the invention can be used for transmitting media in P2P networks.
Description
Technical field
The present invention relates to the communications field, relate in particular to publication medium descriptor and the method, device, the system that obtain medium.
Background technology
In P2P (peer-to-peer) peer-to-peer network, two or more PCs or miscellaneous equipment, the common source that comprises disposal ability (CPU), program and data is shared in direct communication or cooperation on network each other.In the P2P structure, there is not Centroid (or central server) in network, and each node is all being taken on these triple responsibilities of information consumer, informant and information intermediary person simultaneously.Fig. 1 is a kind of common structural P 2 P Overlay (overlay network), and all Peer (node) have formed P2P Overlay.Peer1 can be published to content indexing (Key/Value) above the P2P Overlay by the Put order, and Peer1 finds according to specific P2P rule and is responsible for the root node Peer2 that deposits Key/Value specially in issuing process.Peer2 preserves Key/Value, and Key/Value has write down the pairing Value of each Key (sign), and Value is generally the pairing content of Key (this content can be real content, also can be the source address that this content can be provided).When Peer3 needs same sign (Key), then can initiate the Get order to P2P Overlay, search the pairing Value of Key.Peer 3 finds according to specific P2P rule and is responsible for the root node Peer2 that deposits Key/Value specially.Last Peer2 returns the pairing Va lue of Key (be the content of Peer 1 issue, or the address of the Peer1 of this content can be provided) and gives Peer3.
Fast development along with video traffic, Internet video, high definition technology, following needed media description file of P2P media delivery can not be satisfied with and only contain some simple fileinfos, stored information and distributor information, and needs the media description file to comprise more information.Especially based on P2P VoD (Video-on-Demand) business of burst Key scheduling, need the media description file to comprise more information.
For P2P VoD business based on burst Key scheduling, the user is before obtaining film, at first, obtain descriptor (as: descriptor of film name, film size, film code check, publisher, issue reproduction time, burst division information, each burst or the like) to film by downloading complete media description file.By these information, the user can find the content source of film or the specific burst of film in network, and carries out media delivery with content source and consult, and sets up session connection, obtains required film or the specific burst of film thereby finally obtain from content source.
State in realization in the process of technical scheme, the inventor finds that there are the following problems at least in the prior art:
The user need at first download whole media description file before watching film.This downloading process can cause the user to watch film to have significantly startup time delay before.Along with contained information in the media description file increases, the media description file increases, and can cause the startup time delay of media play more obvious.
