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 (NC) video standards.

Both composite and S-video (Y/C) input formats are sup-

ported. A 2-line comb filter plus a user-selectable chromi-

nance trap filter 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 I2C interface.
