On-Screen Display Controller LSI
Preliminary
Overview
The LC74730M is a CMOS LSI for on-screen display, a
function that displays characters and patterns on a TV
screen under microprocessor control. (The LC74730M
supports the S-VCR format.) The characters displayed
have an 8 × 8 dots structure and a dot interpolation
function is provided. The LC74730M display 10 lines of
24 characters each.
Features
• Screen format: 10 lines × 24 characters (up to 240
characters)
• Character format: 8 (horizontal) × 8 (vertical) (inter-
polation function provided)
• Character sizes: Three horizontal sizes and 3 vertical
sizes
• Number of characters in font: 64 characters
• Display start position
— Horizontal: 64 positions
— Vertical: 64 positions
• Blinking: In character units
• Types of blinking: Two types with approximately
1.0 sec. and 0.5 sec.
• Background color: Four background colors (in internal
synchronization mode)
(For the PAL-M format: 1 color; blue background)
• External control input: 8-bit serial data input format
• Built-in sync separator circuit
• Built-in synchronization recognition circuit: Recognizes
whether or not external synchronizing signals are
present
• Video output: NTSC and PAL-M format composite
outputs, Y-C output
