to input video data in 3 10-bit YCrCb progressive scan format
to facilitate interfacing devices such as progressive scan systems.
Six DACs are available on the ADV7192, 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 (SMPTRE/EBU
N10, MII or Betacam) are supported.
The on-board SSAF (Super Subalias Filter) with extended lumi-
nance frequency response and sharp stopband attenuation
enables studio quality video playback on modern TVs, giving
optimal horizontal line resolution. An additional sharpness
control feature allows high-frequency enhancement on the
luminance signal.
