EVL2510
Evaluation System for AVC2510 Dual-Channel Video
Format Converter
General Description
Features
The EVL2510 is a system that enables evaluation of the key
features of the AVC2510 dual-channel adaptive video converter. 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 functionality. 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 provides a simultaneous (CVBS and component) downconverted version of the same signal being output on the
Primary channel.
Inputs
n Standard Definition Video: 1 CVBS, 1 YPbPr, 1 SCART
(CVBS + RGB with fast blank)
n High Definition Video: 1YPbPr, 480p, 720p and 1080i
n Graphics: RGBHV, up to 165 MHz
Primary Outputs
n Analog: RGBHV or YPbPr, up to 1080p/60
n Digital: 20/24-bit HDMI, up to 1080p/60
Auxiliary Output
n Analog: CVSB, S-Video or YPbPr (480i, 576i),
down-converted from primary output
Functions

n CP3BT26 (CR16C) 16-bit RISC Microcontroller
n 2D Y/C separation and NTSC/PAL/SECAM decoding
n Main channel: 3D Noise Reduction and 3D Deinterlacing
of both Standard and High Definition video (480i, 576i,
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
