GENERAL DESCRIPTION
The ADV7194 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 inter-
facing 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, etc.
The ADV7194 supports NTSC-M, NTSC-N (Japan), PAL N,
PAL-B/D/G/H/I and PAL-60 standards. Input standards sup-
ported include ITU-R.BT656 4:2:2 YCrCb in 8-, 10-, 16- or
20-bit format and 3× 10-bit YCrCb progressive scan format.
The ADV7194 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 170M
NTSC and ITU-R.BT 470 PAL.
