Before or after you import channels with program guide data for a custom lineup, you can change your analog lineup to a digital lineup.
To do this, select ATSC or QAM from the Type drop-down menu.
Should I pick ATSC or QAM?
ATSC is the broadcast standard for over-the-air HDTV. Use this option if your TV source is a digital antenna.
QAM is a standard for HDTV over RF cable. Use this option if you are capturing HD channels from a commercial cable provider, or if your channels are generated in-house.
When a digital option is selected, the appearance of the channel list will change.
ATSC
The following options are available for ATSC channels.
Name
Callsign
Physical Channel
This setting represents the RF frequency on which the channel is broadcast.
Major Channel / Minor Channel
These settings define the location of the data within the stream.
Note: For ATSC, all channel number settings must be entered correctly in order for the tuners to capture a signal.
QAM
The following options are available for QAM channels.
Name
Callsign
Guide Channel
Determines the position of this channel in the SnapStream program guide. This is an arbitrary setting- it does not affect the ability of the tuners to capture the channel.
Physical Channel
This setting represents the RF frequency on which the channel is broadcast.
Program Number
This is the "subchannel" number of the broadcast.
QAM Type
There are several different types of QAM, which use slightly different frequencies. Options are IRC, HRC, and US Cable.
Note: For QAM, the QAM Type, Physical Channel and Program Number must be entered correctly in order for the tuners to capture a signal. The Guide Channel setting is arbitrary and does not affect the ability to tune the signal.
