signals (as specified in the implementation of the TDA9975(A) decoder from Philips
and the HMP8117 decoder from Intersil). In HD mode HREF, VREF, and FREF are
respectively connected to the VIP module pins hrefhd, vrefhd an frefhd. The
supported mode is shown in
this HD mode, the code is expected to be in the U/V stream; to this end, the current
design checks only one of the streams, the U/V stream, for the presence of the
embedded codes, assuming that any information embedded in the Y stream is
identical (see ITU BT 1120, SMPTE 274M standards). The DUAL_STREAM register
must be programmed to 1 in this mode.
Remark: The explicit sync signals are used only in the HD or DUAL_STREAM mode.
