AVC5000

Integrated Dual 3D Video Format Converter

General Description

The highly integrated AVC5000 dual 3D adaptive video con-

verter accepts standard-and high-definition baseband ana-

log and digital video inputs and processes them for display in

single or multiple windows on the television screen. Stan-

dard video formats up to 1080p resolution with a 60 Hz frame

rate are supported. The converter is comprised of two main

blocks-a universal front-end and a dual-channel display pro-

cessor. The universal front-end accepts standard- and high-

definition video formats, PC graphics formats and DVI sig-

nals, and decodes the signals into component video or RGB.

Any two outputs from the universal front-end can be selected

for the dual-channel display processor. The dual 3D archi-

tecture features two 3D decoders, two 3D noise reducers,

two 3D deinterlacers, two high-order scalers for size and

aspect ratio scaling, luma and chroma enhancement, frame-

rate-conversion, adaptive contrast enhancement, multi-

picture functions (PIP/PAP/POP) including side-by-side dis-

play of two full-quality images on a wide screen, intelligent

color remapping and overlay of a bit mapped on-screen-

display (OSD). The output signal formats include analog

RGB or YPbPr for CRT displays and TTL or LVDS for flat

panel or microdisplay.
