GENERAL DESCRIPTION

In closed caption mode, text can be decoded directly from the composite video signal and displayed on the screen with assistance from the processor's digital signal processing capabilities. The character control mode provides access to the full set of attribute controls. The modification of attributes is allowed on a character-by-character basis. The insertion of control characters permits direction of other character attributes. Display attributes, including underlining, italics, blinking, eight foreground/background colors, character position offset delay, and background transparency, are made possible through a fully customized 512 character set, formatted in two 256 character banks.
