Picture BooSTTM
7.2
PictureBooST
TM
RGB Decoder
The STV9937 can receive the coordinates of the area to BooST through the RGB channel or
through I2C bus.
The Picture BooST
TM
area coordinates are coded as follows:
7.2.1
Data Sent Using I2C
Before sending data to the corresponding registers, the PBVM bit must be set to 1. Then the
coordinates can be sent to the corresponding address, see
Table 36
:
Row 1, Col 3 to 6 for X1, X2 coordinates
Row 1, Col 7 to 10 for the Y1, Y2 coordinates.
7.2.2
Data Sent Using the RGB Channel
The Picture BooST
TM
Software sends coordinate data through the RGB channel:
The Red channel contains the X1, X2 and Y1, Y2 coordinates information
The Green Channel contains a specific activation code
The Blue Channel contains the clock signal.
The Decoder stores the coordinates values to the corresponding address:
Row 1, Col 3 to 6 for X1, X2 coordinates
Row 1, Col 7 to 10 for the Y1, Y2 coordinates.
X1 and X2 are referred to the HSYNC signal, the resolution is F
PIXEL1
(from 30 Mhz to 60 Mhz)
