Description of drawings
Fig. 1 is according to the described a kind of process blocks schematic diagram of realizing the multicast program preview method of the embodiment of the invention.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
Be the described a kind of process blocks schematic diagram of realizing the multicast program preview method of the embodiment of the invention with reference to figure 1.Detailed process is as follows:
Step 110:DSLAM equipment is by communicating by letter user's multicast authority control table and multicast program preview control table on the acquisition equipment with business management system (SMS, ServiceManagement System).The multicast authority control table information that DSLAM equipment obtains this equipment user is to communicate acquisition by DSLAM equipment and SMS system, and being OSS (Operations Support System, the Operational Management System) system of SMS system and IPTV, the user multicast power control table information in the SMS system communicates acquisition.
Step 120: user's preview multicast channel, user's set-top box (STB, Set Top Box) produces IGMP (Internet Group Management Protocol, the Internet group message protocol) join (a joining request) message and send to DSLAM equipment.
Step 130:DSLAM equipment receives IGMP Join message, judges this user's authority according to described multicast authority control table.After DSLAM equipment received user multicast request IGMP Join message, according to the multicast ip address that message carries, this user of inquiry was to the authority of this channel in the user multicast power control table.
Step 140: through judging that the authority that draws this user is the preview authority.
The user is the preview authority, represents that then the user will carry out preview, if other authorities otherwise processed then.User's multicast authority control only allows the user to add the multicast group of mandate or allows the multicast group of preview.Its authority of watching of control on user port, authority to each multicast group have forbid, preview, permission.
