Abstract
The invention discloses a multi-user sharing on-demand achieving system and an achieving method thereof. The achieving method comprises that (1) an A user confirms watching an X program and a client device A establishes a point-to-point data IP (Internet Protocol) unicast transport connection with a video server; (2) a signaling monitoring and agent module establishes an interior observation list according to the X program watched by the A user; (3) a B user confirms watching the X program, the signaling monitoring and agent module searches in the interior watching program list to find that whether the program watched by a client device B is same to the program watched by the client device A and commands a data transfer module to filter data of the X program watched by the client device A to send to the client device B. The multi-user sharing on-demand achieving method can intelligently dispatch live broadcast businesses to be transferred to the client devices in an IP unicast channel and can substantially reduce network bandwidth repeatedly occupied by every live broadcast stream.
Description
Technical field
The present invention relates to a kind of system and its implementation that realizes multiple users share program request, belong to program request automation field.
Background technology
In existing IP transmission network, there are two kinds of transmission meanss, one is the transmission means of multicast, being characterized in that a data flow is transmitted in IP network can be received simultaneously and process by the recipient of any amount, advantage is to save bandwidth, from the source of data, to the transmitting procedure of the destination of data, only occupy a physical transfer bandwidth, so all recipients that shortcoming is data can only receive identical data, cause all recipients can only watch identical program.
Another point-to-point transmitted in both directions mode, in CHINA RFTCOM Co Ltd, user uses the mode of point-to-point transmitted in both directions to watch the step of programme televised live as follows:
(1) party A-subscriber uses the program inventory on client device A browser server;
(2) party A-subscriber determines and to watch X program, client device A set up and video server between the point-to-point IP unicast transmission of data connect, start to receive receipt decoding and be shown to party A-subscriber and watch;
(3) party B-subscriber uses the program inventory on client device B browser server;
(4) party B-subscriber determines and to watch X program, client device B set up and video server between the point-to-point IP unicast transmission of data connect, start to receive receipt decoding and be shown to party B-subscriber and watch.
By above-mentioned steps, can be found out, user can use the mode of program request to watch any program, each user can watch identical or not identical program by this transmission means program request, even if shortcoming is different user, point finishes identical program, same data need to be replicated N part to different recipients, and the transmission of each data can occupy corresponding data transfer bandwidth.
Summary of the invention
The object of the present invention is to provide a kind of system and its implementation that realizes multiple users share program request, mainly solve existing user flexibly request program watch and same transfer of data occupies the problem of bandwidth.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of system that realizes multiple users share program request, comprise video server, the backbone network being connected with video server and access network equipment, the intelligent edge device being connected with access network equipment with backbone network, the client device that a plurality of and intelligent edge device is connected, described intelligent edge device comprises the network side module being connected with access network equipment with backbone network, the data forwarding module being connected with network side module, the Access Network module being connected with data forwarding module respectively, monitoring signaling and proxy module, data relay module, described each client device is while and video server all, Access Network module, data forwarding module connects.
An implementation method that realizes the system of multiple users share program request, comprises the steps:
(1) party A-subscriber uses the program inventory on client device A browsing video server;
(2) party A-subscriber determines and to watch X program, client device A set up and video server between the point-to-point IP unicast transmission of data connect, client device A receives data decoding and is shown to party A-subscriber and watches;
(3) data forwarding module simultaneously by the data filtering of X program out and by control signal data retransmission wherein to monitoring signaling and proxy module, monitoring signaling and proxy module are set up inside and are watched the rendition list;
(4) party B-subscriber uses the program inventory on client device B browsing video server;
(5) the definite X program of watching of party B-subscriber, data forwarding module is out transmitted to monitoring signaling and proxy module afterwards by control signal data filtering, whether monitoring signaling and proxy module watch on the rendition list program that search finds that client device B watches and client device A watching at present program in inside is identical, if identical, the media data of the X program that monitoring signaling and proxy module order data forwarding module are being watched client device A filters out, after data relay resume module, return to data forwarding module and send to client device B;
(6) client device B completes reception, decoding and the demonstration of data.
Particularly, in described step (5), the media data of the X program that data forwarding module is being watched client device A filters out, and after data relay resume module, returns to data forwarding module and sends to client device B, and concrete steps are:
(a) monitoring signaling and proxy module are responded the requirement of customer end B, determine X program that client device B the watches position in IP tunnel;
(b) data forwarding module is transmitted to data relay module by media data and carries out data transaction;
(c) data relay module is broadcast away media data by IP tunnel.
Compared with prior art, the present invention has following beneficial effect:
(1) the present invention can dispatch intelligently live broadcast service at IP unicast passage repeating to client device, use the method can significantly reduce the network bandwidth that each live TV stream repeats to occupy;
(2) the present invention can be effectively between the transmission means of broadcast and the transmitted in both directions mode of IP flexible dispatching, when finding that user uses IP transmitted in both directions mode to watch same program, can automatically by the transmission means of broadcast, carry out Program Transport, can reduce significantly the occupied bandwidth of program transmission like this, watch that the bandwidth that the number of users of same program saves is more at most just more;
(3) system configuration of the present invention is simple, practical, is applicable to very much large-scale promotion and uses.
Accompanying drawing explanation
Fig. 1 is the system block diagram of the present invention-embodiment.
