HMP8116
NTSC/PAL Video Decoder
Description
The HMP8115 is a high quality NTSC and PAL decoder with
internal A/D converters. It is compatible with NTSC M, PAL
B, D, G, H, I, M, N, and combination N (N
C
) video standards.
Both composite and S-video (Y/C) input formats are sup-
ported. A 2-line comb 鏗乴ter plus a user-selectable chromi-
nance trap 鏗乴ter provide high quality Y/C separation. User
adjustments include brightness, contrast, saturation, hue,
and sharpness.
Data during the vertical blanking interval (VBI), such as
closed captioning, widescreen signalling and teletext, may
be captured and output as BT.656 ancillary data. Closed
captioning and widescreen signalling information may also
be read out via the I
2
C interface.
