
the Mini Carousel.

whose frequency matches the marker Frequency (typically 999Mhz) is considered an SDV
channel. The total number of channels with that marker frequency relative to the total
number of channels defined by the CableCARD is displayed as "n SDV channels out of
x."
Currently Homing—Yes or No. Yes if the device is currently trying to collect a Mini

Carousel.
Mini Carousel Received—Yes or No. Yes if a Mini Carousel has ever been collected.



