AVC2510
Dual-Channel Video Format Converter

General Description

The AVC2510 dual-channel adaptive video converter ac-
cepts PC graphics and standard- and high-definition digital
video inputs and processes them to produce high quality
output in any desired standard video format up to 1080p
resolution with a 60 Hz frame rate. The converter contains
one full quality 3D video pipeline and one secondary pipeline
that perform scaling to support picture-in-picture and thumb-
nail functions. Extensive noise reduction functions, adaptive
contrast enhancement, edge enhancement and intelligent
color remapping enables optimum image rendering. TwinD
architecture provides simultaneous output of a primary high-
or

standard-definition

data

stream

and

secondary

standard-definition version of the same data stream, allow-
ing easy implementation of a monitoring or time-shifting
function.
