Chapter 1 Enabling DVR Service
4 Click File, and then select Open. The Set Up Display Channel Map window
opens for the channel map you selected.
5 Scroll through the Available Services field until you see the DVR service listed,
and then click the DVR service to select it.
6 Scroll through the Channel Slot field until you see the channel slot to which you
want to assign the DVR service, and then click the channel slot to select it.
7 Click Add. The DVR service moves from the Available Services field to the
Channel Slot field you selected.
8 Click Save to save the channel map information in the DNCS database and close
the Set Up Display Channel Map window. By default, the system waits 20
minutes to build new channel maps. However, the amount of time that elapses
between a change to a channel map and the time that a new channel map is built
and broadcast to DHCTs varies according to the SAM Update Timer setting. For
this reason, allow an appropriate amount of time to pass before testing DVR
service to verify that channels were added.
9 Repeat steps 3 to 8 for each channel map that requires DVR service, and then go
to step 10.
