Case: Cannot Be Authorized (
dcc_selection_type
 = 0x09) 
If the 
dcc_selection_type
is specified to be of type 0x09, and if the DCCRR has been tuned by the 
viewer to a major and minor channel number specified by the 
dcc_from_major_channel_number
and the 
dcc_from_minor_channel_number
for which the viewer is not authorized (due to conditional access), the 
DCCRR shall promptly, upon determination of the unauthorized status, tune to the 
dcc_to_major_channel_number
and 
dcc_to_minor_channel_number
. The action of this mechanism provides 
an ability to “redirect” viewers to an alternate channel in the event they are not authorized to view 
the requested channel.
