MTV030

On-Screen Display with Auto-Sizing Controller

GENERAL DESCRIPTION

MTV030 is designed for monitor applications to display

built-in characters or fonts onto monitor screens. The dis-

play operation occurs by transferring data and control infor-

mation from the micro-controller to RAM through a serial

data interface. It can execute full-screen display automati-

cally, as well as specific functions such as character back-

ground, bordering, shadowing, blinking, double height and

width, font by font color control, frame positioning, frame

size control by character height and row-to-row spacing,

horizontal display resolution, full-screen erasing, fade-in/

fade-out effect, windowing effect, shadowing on window

and full-screen self-test pattern generator.

MTV030 provides true 512 fonts including 496 standard

fonts and 16 multi-color fonts and 2 font sizes, 12x16 or

12x18 for more efficacious applications. So each one of the

512 fonts can be displayed at the same time. The full OSD

menu is formed by 15 rows x 30 columns, which can be

positioned anywhere on the monitor screen by changing

vertical or horizontal delay.

The auto sizing video measurement module measure

the timing relationship among HFLB, VFLB, and R, G, BIN

at the speed related to the OSD resolution. MCU can get

the measurement data, active video, front porth and back

porth, through I

2

C bus read/write operation to keep the

appropriate display size and center.
