EVL2510
Evaluation System for AVC2510 Dual-Channel Video
Format Converter
General Description
The EVL2510 is a system that enables evaluation of the key
features of the AVC2510 dual-channel adaptive video con-
verter. The system consists of a 2-channel analog input card
with OSD generator, an HDMI input card, the main AVC2510
card, an output card and an optional CPU card. The system
accepts a wide range of analog inputs including composite
(CVBS), interlaced standard definition component or RGB
(SCART), HD component, VGA as well the digital HDMI
signal. The AVC2510 can take any two input signals, treating
one as the primary channel and the other as the secondary
PIP channel, merge them in PIP, PAP or POP formats, and
then blend the OSD on top using alpha-blending. In the
Primary channel, 3D noise reduction and deinterlacing are
performed, followed by high order scaling. In the Secondary
PIP channel the processing is in 2D, with similar functional-
ity. Three types of output signals are supported: The Primary
Output provides High Definition RGB/YPbPr (analog) and
HDMI (480p, 576p, 720p, 1080i or 1080p/60) from any input
source, up or down-converted. The Secondary output pro-
vides a simultaneous (CVBS and component) down-
converted version of the same signal being output on the
Primary channel.
Features

480p, 720p 1080i)
n PIP channel: Programmable high quality 2D scaling and
aspect ratio conversion
n Adaptive contrast enhancement and intelligent color
remapping
n Overlay/blending of external digital OSD
