GENERAL DESCRIPTION
The ADV7192 is part of the new generation of video encoders
from Analog Devices. The device builds on the performance of
previous video encoders and provides new features like interfac-
ing progressive scan devices, Digital Noise Reduction, Gamma
Correction, 4× Oversampling and 54 MHz operation, Average
Brightness Detection, Black Burst Signal Generation, Chroma
Delay, an additional Chroma Filter, and other features.
The ADV7192 supports NTSC-M, NTSC-N (Japan), PAL N,
PAL M, PAL-B/D/G/H/I and PAL-60 standards. Input standards
supported include ITU-R.BT656 4:2:2 YCrCb in 8-bit or 16-bit
format and 3× 10-Bit YCrCb progressive scan format.
The ADV7192 can output Composite Video (CVBS), S-Video
(Y/C), Component YUV or RGB and analog progressive scan in
YPrPb format. The analog component output is also compatible
with Betacam, MII, and SMPTE/EBU N10 levels, SMPTE
170 M NTSC, and ITU–R.BT 470 PAL.
Please see Detailed Description of Features for more informa-
tion about the ADV7192.
