Teletext Level 2.5 is backwards compatible with Teletext Level 1 and Level 1.5.

The Teletext Level 2.5 specification defines following elements as parts of a level 2.5 layout:

Objects

Objects are groups of attributes (Color, Font,...), characters and graphics (Logos) that can be set on any position of the teletext page and change the appearance of the Level 1 Layout.

Graphics/Logos

On each teletext page DRCS characters can be defined on a pixel basis. Each DRCS character consists of 12x10 pixels. Up to 24 DRCS characters (dynamically redefined character set) can be used on each teletext page to form a graphic image or a logo.

Color palettes

On each teletext page 32 colors from a color palette can be used. 16 colors of the color palette can be chosen from the main color palette out of 4096 colors.

FAB HiLevel Teletext Editor supports you when designing Level 2.5 layouts by

Visual design
When designing Layouts you are always using a Level 1 teletext page in the background which you are enhancing with Level 2.5 elements. The final Level 2.5 teletext page is visible all the time.

Graphics import
Graphic files in formats BMP, PCX, GIF, JPG and TGA can be read directly and converted into the Level 2.5 format. The size and position of the image can be modified at any time. If more than 24 DRCS characters are required for the graphic image then the most similar characters out of the smooth mosaic graphics character set will be chosen automatically.
