Multibit coded data words are supplied by a data source, such as a memory (14), to a character generator circuit (50) which controls the display of data characters on the face of a video display screen. These coded data words include at least character codes and video modifier codes. Dot pattern video signals are provided for forming the dot pattern image represented by a coded data character. These dot pattern video signals are modified in accordance with a video dot pattern modifier (62) so that the video image is formed with the modification made thereto. The video modifiers are selectable so that one or more of a plurality of video modifiers may be in effect for a given data character. Additionally, each of these pluralities of modifiers may be programmably chosen from one of a second plurality of available video modifiers. </p> |
