Notes:
1. 1080p/24 or 1080p/30 output formats are available on HDMI, if those formats are presented to
the set-top box at its input. Incoming video formats will not be converted to either of these for
output. Output of these formats is under software control.
2. Axiom DVR Middleware for tru2way (formerly OCAP) support is recommended only for the
8600 models that have a minimum of 384 MB RAM.
3. Boot Partition provides space on the hard drive for storing the set-top’s core software.
Additional non-core application storage space may be made available on the hard drive. The
Boot Partition is analogous to a portion of the role traditional flash memory serves on non-hard
drive set-tops.
