Embodiment
The prerequisite of embodiments of the invention hypothesis is: content disposition is on the streaming media server at edge; Central medium server has the content on all electric program menus in theory; STB (set-top box) is usually from local (or claiming fringe node) media server broadcast program content.
One of the present invention, a kind of VOD frequency processing unit
As shown in Figure 1, frequency processing unit of the present invention is connected between the control centre's data server and central control server of video on-demand system, comprises being redirected and information gathering module 11 and intelligent distribution module 12.
Be redirected and information gathering module 11, be used for the on-demand content on local streaming media server not is redirected according to the information that inquires from described control centre data server 3, and collect this redirection information and write in the described control centre data server 3, so that generate statistical information;
The present invention's two, a kind of VOD frequency treating method
This method comprises based on the video on-demand system that comprises control centre's data server and central control server:

In the foregoing invention, what be redirected employing is that RTSP (Real Time Streaming protocol real-time stream media protocol) is redirected (Redirect) mode, if also the content of i.e. end user's program request is not on local streaming media server, central control server can be located on the suitable streaming media server, this with prior art in all requests all sent to the mode that Centroid handles compare, its major advantage is the downlink network flow that has rationally distributed huge, avoid overhead, improved the service efficiency of streaming media server.
The distribution of content is dispensed on network to be carried out during the spare time, had both guaranteed the smoothness that the user watches, and can make full use of the not busy Time Bandwidth of network again.
Referring to Fig. 1, STB (set-top box) terminal is sent order request (RTSP request) to central control server, when central control server finds that on-demand content is not on local streaming media server, search best fringe node (also being and the nearest server of user), so reply redirected (RTSP is redirected) message to STB, STB finds the final purpose media server according to the address of carrying in the redirect message.In this process, the corresponding actions result can be write control centre's data server (so that generate statistical information), if make mistakes then can write down the daily record that makes mistakes.The decision of final purpose server can be according to the load of current media server, and STB is to the key elements such as distance of media server.
Historical according to user's program request and statistics that make shows: 80% program request concentrates on 20% the backing.Thereby when disposing media server, can only have central medium server with 80% cold, there is the streaming media server at edge in 20% backing.
Can be the attribute that each on-demand content is provided with a focus by name in view of the above, so-called focus just is meant the number of times of this program of program request in set period and total video-on-demand times percentage in this period.The program request incident can influence the renewal of focus value.Can design certain strategy (as the distribution cycle etc., level and smooth flow etc.) according to focus and the attribute that makes up other, discharge task scheduling, the automatic smoothing distribution of control programme content and transmitting.This is a typical closed-loop reponse system.
Intelligent distribution mode is divided into initiatively and passive two kinds.
Passive Mode is by intelligent distribution module calculating and monitoring and the relevant factor/variable of control centre's data server statistical information, determine which content to distribute or to upgrade, when meeting or exceeding set definite value, can carry out the adding/deletion of content between media server (can dispatch by the backstage, when system loading is not busy, carry out, level and smooth to guarantee network and flow system flow).
Aggressive mode is applied to the distribution of the fresh content of input system, and system can distribute the film that satisfies condition automatically.If, then can set higher initial temperature if also the i.e. film of new issue deduction in advance is comparatively popular, be directed at first in the system at film, just directly be distributed on the fringe node of appointment.This pattern is higher to fresh content distribution efficient in enormous quantities.Compare with the pattern of distributing (Passive Mode) behind the collection IP Information On Demand again, major advantage is to have introduced artificial interference, and the reaction of system is comparatively quick and have expection, has improved the service efficiency of streaming media server.The distribution of content is dispensed on network to be carried out during the spare time, had both guaranteed the smoothness that the user watches, and can make full use of the not busy Time Bandwidth of network again.
Distribution policy comprises the distribution cycle, the combination of key elements such as content focus value and current media server capacity.Add with the deletion action and also can upgrade relevant information, also provide input for next step processing.
