System Description
Preliminary Data Sheet
4.9
On Screen Display (OSD)
4.9.1
The on screen display allows to insert a block of 5 characters into each of the PIP
pictures. The characters are placed in a box (background) whose width is 64 pixels and
height is 12 lines. This box is placed in the upper left corner of the PIP picture. 64
different characters are stored in a character ROM. Each character is defined by a pixel
matrix consisting of 10 lines and 12 pixels per line. A doubling of the character’s height
and width is achieved by
CHRDHW
. The OSD starting position is not influenced.
OSD display is also possible if PIP is switched off (
DISPMOD
=’100011’). Now 3 lines of
20 characters each are displayed at the PiP position.

4.9.2
The characters are programmed via I2C bus using a 7 bit code which is identical with the
ASCII code except for some of the special characters. The codes are stored in a
character RAM consisting of 60 cells. The character codes can be transmitted in two
ways: each character position can be addressed separately by its 7 bit address or the
characters can be written consecutively starting at an arbitrarily chosen position. In this
case the address is increased automatically. The 7 bit address consists of two parts: the
4 MSBs are used to chose one of the partial pictures and the 3 LSBs to select one of the
5 characters per block.
