Abstract
The invention provides a kind of content-based coding and realize content location and shared method between net, it comprises: (1) content encoding: Content Management Platform CMS distributes the unique content encoding of the whole network, the necessary information that this content encoding content is play for the content of injecting; (2) network node coding: adopt VGT video global title, for each video network node is provided with Unified coding; (3) content distribution: the node that content is injected is by carrying out the whole network issue of content information between the Content Management Platform CMS; (4) the content strange land obtains: content distributing network CDN determines to preserve the network node of this content according to the corresponding relation of content encoding and network node coding, obtains this content to this network node.The present invention has realized that the content single-point injects, the whole network service, can significantly reduce service provider's Internet resources.This method can be applied to all video fields, as IPTV, ChinaVnet etc.
Description
Technical field
The present invention relates to the content location in all video fields and share the single-point injection of realization video content, overall share service.
Background technology
Progress and user's improving constantly along with society to high-quality life seek, Video service, especially the interactive video service forms huge industry gradually, video content is the basic element of Video service, after video content injects video network at present, because it is invisible to the strange land user, can only provide service to the local user, so realize that a content service is in the whole network user, just need preserve the copy of this content at each service network, so not only take a large amount of Internet resources, the copyright of content is safeguarded caused difficulty simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of content-based coding and realize content location between net and the method for sharing, realizing that the content single-point injects, the whole network service, thereby realized that overall content is shared, location and distribution.
The technical problem underlying that the present invention solves is the coded system of content, by the whole network addressing technique of coding and the whole network distribution of content information.
The invention provides a kind of content-based coding and realize content location and shared method between net, it comprises:
(1) content encoding
Content Management Platform CMS distributes the unique content encoding of the whole network, the necessary information that this content encoding content is play for the content of injecting;
(2) network node coding
Adopt VGT video global title, for each video network node is provided with Unified coding;
(3) content distribution
The node that content is injected is by carrying out the whole network issue of content information between the Content Management Platform CMS;
(4) the content strange land obtains
Content distributing network CDN determines to preserve the network node of this content according to the corresponding relation of content encoding and network node coding, obtains this content to this network node.
In the said method, the necessary information that is comprised in step (1) content encoding comprises ground domain information, video format and content type.
In the said method, described video format comprises MP2, MP4, H264 or WMV9.
In the said method, described content type comprises live TV stream, Vod film or advertisement.
The present invention is based on the technology that content encoding realizes that the content of the overall situation is shared, located and distribute, and has realized that the content single-point injects, the whole network service, can significantly reduce service provider's Internet resources.This method can be applied to all video fields, as IPTV, ChinaVnet etc.
Description of drawings

Fig. 2 is a content service business process map between the net of the embodiment of the invention.
Embodiment
Below in conjunction with accompanying drawing, describe embodiments of the present invention in detail.
According to the present invention, the content that single-point injects can realize that the overall situation is shared.
With reference to Fig. 1, all video traffic platforms (containing IPTV) all have CMS Content Management Platform and content distributing network CDN two large divisions, CMS is mainly used to that content is injected and maintenance content descriptor and operation information, and CDN is mainly used to realize in the net of video content, distribution and scheduling between netting.
The content service operation flow as shown in Figure 2 between net.A content is injected to a certain CMS node (being designated as CMS1) by content supplier, and system generates the unique content encoding of the whole network, and content encoding is published to a certain CDN node (being designated as CDN1).Simultaneously, through content distribution operation, content encoding is published to another node CMS2, but content is kept at still among the origin node CDN1.As user during to another CDN node (being designated as CDN2) request service, on CDN1, then CDN2 can provide corresponding service by CDN1 to the user to the CDN1 request content to CDN2 according to the positional information of VGT locating content.
Be that example is introduced its concrete implementation step with the IPTV system below:
Step 1, content are injected: to service network uploaded videos content, after content was injected, CMS generated unique content encoding for content to the operator automatically by Content Management Platform CMS.
With the IPTV system is example, and the content encoding form can be defined as follows:
20, with numeral, its form is: " W1-W8S1S2S3-12 "; Wherein,
(1) " W1-W8 " sign content-location information, wherein W1, W2 are country code, and W3-W6 is an area code, and W7, W8 are IPTV node serial number in the metropolitan area network;
(2) " S1S2 " sign content type, as " 01 " expression live TV stream, " 02 " expression Vod film, " 03 " expression advertisement;
(3) " S3-12 " is the internal number of content at this intranodal.
The example of particular content coding is as follows: 86002501020000000001, wherein:
(1) " 86002501 " sign content-location information, wherein 86 is country code, and 0025 is area code, and 01 is IPTV node serial number in the metropolitan area network;
(2) " 02 " represents the Vod film;
(3) " 0000000001 " is the internal number of content at this intranodal.
Like this, just realized the content encoding that the whole network is unique.
Step 2, content distribution: the operator can issue the content information of own node by Content Management Platform CMS other node in the whole network of this node, other node obtains can independently runing behind this content information and providing information on services to the user, but the entity of content still is kept in the storage of origin node.
The location of step 3, strange land content and obtaining: the corresponding relation (VGT video global title) of maintaining network node and ground domain information in the content distributing network CDN of distributed flow media, when certain video content of user's program request, CDN orients the positional information of this content stores automatically according to the ground domain information in the content encoding, and the VGT table is that example has following information at least with the IPTV business:
(1) " W1-W8 " sign content-location information, wherein W1, W2 are country code, and W3-W6 is an area code, and W7, W8 are IPTV node serial number in the metropolitan area network;
(2) the visit IP address information of this IPTV node CMS;
(3) the IP address information of this IPTV node CDN central server;
The record format example of concrete VGT table is as follows, wherein:
The IP of the IP center C DN of address code CMS
860025 10.40.90.1 10.40.9.100
The CDN of step 4, local service node obtains this video content to the network node of preserving this content by standard interface according to the content location information that VGT orients, and plays to the user simultaneously, for the user provides service.
