GENERAL DESCRIPTION
The ADV7190/ADV7191 is an integrated Digital Video Encoder
that converts digital CCIR-601/656 4:2:2 8-bit or 16-bit com-
ponent video data into a standard analog baseband television
signal compatible with worldwide standards.
Six DACs are available on the ADV7190/ADV7191, each of which
is capable of providing 4.33 mA of current. In addition to the
composite output signal there is the facility to output S-Video
(Y/C Video), RGB Video and YUV Video. All YUV formats
(Betacam, MII and (SMPTE/EBU N10) are supported.
Digital Noise Reduction allows improved picture quality in remov-
ing low amplitude, high frequency noise. The block diagram below
shows the DNR functionality in the two modes available.
