Bandwidth Reclamation Parameters
The Bandwidth Reclamation feature uses five timers and one threshold setting to
control its operation, as follows.
Settop Reporting Interval (StbReportInterval) is the time period of the LUA
Report. It is set to a default value of 1 hour by the USRM and is located on the
Applications.McmisServer.STB Configuration page of the USRM Web UI. The
StbReportInterval is sent to the STB client via the mini-carousel. The LUA is sent
by the STB client to the USRM and contains the time stamp of the last user
activity that occurred during the reporting interval. Default = 1 hour.
Note: This value should always be less than Recapture Time for actual field
Note: This value should always be less than Recapture Time for actual field
applications.
Recapture Time is the time period after which a Bandwidth Reclamation banner
is displayed on the set-top box. In a DNCS network, this value is provisioned by
the SDV Manager, set at the DNCS during source provisioning, and displayed on
the Applications.SdvSm.Offered Progs Base page of the USRM. If, after this time
period expires, a USRM has received no LUA reports, the server will send an
EventIndication to the set-top box commanding the client to display a
Bandwidth Reclamation banner on the TV screen. This banner asks, essentially,
"Is anyone really watching out there? If so, please press a button on the remote".
Default = 4 hours. Minimum = 2 hours.
In a non-DNCS system, the Recapture Time must be provisioned by the system
In a non-DNCS system, the Recapture Time must be provisioned by the system
administrator (usually with a configuration file) as part of the Offered Programs
table.
Recapture Acknowledgement Time (RecaptureAckTime) is the amount of time
the subscriber has to respond to the Bandwidth Reclamation banner. In a DNCS
network, this value is provisioned by the SDV Manager, set at the DNCS during
source provisioning, and displayed on the Applications.SdvSm.Offered Progs
Base page of the USRM. During this time period, bandwidth cannot be reclaimed
by the server. If the subscriber does respond to the banner, the server will
"know" there is a user watching the program and will send a command to the
set-top box to remove the banner. The server will also clear all its timers and will
NOT reclaim the subscriber's bandwidth. If the subscriber does not respond,
after this time period expires the server may reclaim the bandwidth if it is
needed. Default = 10 minutes.
In a non-DNCS system, the Recapture Acknowledgement Time must be
In a non-DNCS system, the Recapture Acknowledgement Time must be
provisioned by the system administrator (usually with a configuration file) as
part of the Offered Programs table.
STB Bandwidth Reclaim Timeout is the amount of time the Bandwidth
Reclamation banner is displayed on the subscriber's TV screen. It is set to a
default value of 5 minutes by the USRM and is located on the
Applications.McmisServer.STB Configuration page of the USRM webUI. The
STB Bandwidth Reclaim Timeout is sent to the STB client via the mini-carousel.
