6.2.5 (Optional) Configuring the Multicast Preview
Multicast preview is an advertising method provided by carriers for ISPs. The purpose is to allow
users to have an overview of a program so that the user can determine whether to request for the
program. The MA5616 can control the duration, interval, and count of user previews through
the configuration of the multicast preview.
Prerequisites
The program matching mode of the multicast VLAN must be the static configuration mode.
Context
Multicast preview is an advertising method provided by carriers for ISPs. The purpose is to allow
users to have an overview of a program so that the user can determine whether to request for the
program. To protect the legitimate interests of ISPs, the duration, interval, and count of user
previews need to be controlled. The MA5616 controls the program preview of the user through
the configuration of the multicast preview.
l
Preview duration: After a user with the preview rights goes online, the user can watch the
program that can be previewed but the user is restricted by the preview duration. When the
preview time expires, the user will go offline.
l
Preview interval: When the preview time expires, the user who is previewing a multicast
program will go offline. The user can request for the program again only after the configured
preview interval expires.
l
Preview count: Refers to the count of program previews that a user can request for a
multicast program in a period of 24 hours (the start time can be set). If the preview count
reaches the configured preview count, the user cannot preview the program.
The multicast preview function is implemented through the binding of the preview profile to the
multicast program.
NOTE
One multicast program can be bound with only one preview profile, but one preview profile can be referenced
by multiple multicast programs.
Procedure
Step 1
In global config mode, run the
btv
command to enter BTV mode.
Step 2
Enable the multicast preview function globally.
NOTE
By default, the multicast preview function is enabled globally. You can run the
igmp preview { enable |
disable }
command to change the configuration.
Step 3
Configure the preview profile.
Run the
igmp preview-profile add
command to configure the multicast preview profile.
The system has a default preview profile with index 0, which can only be modified and cannot
be deleted.
