This
information
includes
everything
product
developers
need
to
know
for
building
native
2K
SDI
equipment.
Of
course,
all
Blackmagic
products
can
be
updated,
so
if
the
television
industry
adopts
an
alternative
SDI-based
film
standard,
we
can
add
support
for
that
too!
Frame Structure

at
23.98,
24
or
25
frames

second
as
a
Progressive
Segmented
Frame.
Active
video
is
2048
pixels
wide
by
1556
lines
deep.
Total
lines
per
frame
:
1650
Active
words
per
line
are

One
word
consists
of
a
10-bit
sample
for
each

the
four
data
streams,
i.e.,
a
total
of
40
bits.

Transport Structure
Based
on
SMPTE
372M
Dual
Link
mapping
and
SMPTE
425M-B
support
for
mapping
SMPTE
372M
into
a
single
3
Gb/s
link.
Timing

and
line
CRC
insertion
is
the

During
active
video,
10-bit
Red,
Green
and
Blue
data
is
sent
in
the
following
sequence:
Optional
ancillary
data
is
inserted
into
both
virtual
interfaces.
At
present,
only
audio
data
is
included:
as
per
standard
HD
audio
insertion
(SMPTE
S299M)
the
audio
data
packets
are
carried
on
data
stream
two
and
audio
control
packets
are
carried
on
data
stream
one.
