Four character sets are available in the device. A set can
consist of alphanumeric characters as required by the
WST or US Closed Captioning, Customer definable
On-Screen Display characters, and Special Graphic
characters.
CC: Only a single character set can be used for display
and this is selected using the Basic Set selection
TXT18.BS<1:0>. When selecting a character set in
CC mode, the Twist Set selection TXT19.TS<1:0> should
be set to the same value as TXT18.BS<1:0> for correct
operation.
TXT: Two character sets can be displayed at once. These
are the basic G0 set or the alternative G0 set (Twist Set).
The basic set is selected using TXT18.BS<1:0>.
