Virtual Channel
In digital channels, a virtual channel is used. A virtual channel
is a function that enables users to watch a channel by selecting
a virtual channel number regardless of the region of the user.
Run Auto Channel Scan for digital broadcasts, tune in to a UHF
channel number according to the region for terrestrial broad-
casts, or tune into a channel number allocated by the cable
broadcasting station for a cable TV network, and then select a
displayed virtual channel.
For example, even if you tune into channels UHF 14(MBC),
15(KBS1), 16(SBS), 17(KBS2) and 18(EBS) broadcast from
Kwanak mountain in Seoul, you can watch the channels using
virtual channels such as 11-1(MBC), 9-1(KBS1), 6-1(SBS), 7-
1(KBS2) and 10-1(EBS) regardless of your region and the
actual local channel number. The virtual channel numbers may
be used nationwide, but the virtual channel numbers may vary
depending on the local broadcasting stations.
(Since the digital channel numbers may vary depending on
your region and can be changed by the broadcasting policy,
ask your local broadcasting station or regional cable TV net-
work company about the channel numbers.) If the virtual chan-
nel numbers are saved and the TV set can receive digital
broadcasting, you can watch a digital channel by pressing the
DTV+ button and pressing the first two digits of the correspond-
ing virtual channel number.
