Video Processor Description
The 9903-UDX-ADDA features a up/down/cross-convert scaler, frame sync,
and user-adjustable aspect ratio control and zoom control. The
9903-UDX-ADDA video subsystem also provides the functions described
below.
Input Video Select
A GUI-based control allows the card to select from up to two 3G/HD/SD-SDI
inputs, and a SD CVBS or HD/SD YPbPr component analog video input. For
analog inputs, waveform-based ancillary data is preserved for extraction and
usage later in the card processing chain. Analog video processing uses 10-bit
processing with 5-line adaptive comb filtered SD Y/C separation.
The input can be selected using DashBoard manual control, set to failover to
an alternate input upon loss of the target input, and can be externally selected
via a GPIO interface. An input
Allowed Rasters
and
Allowed Frame Rates
filter
allows inputs to be filtered (screened) for only user-allowed raster sizes and
frame rates, with unallowed raster/rates being rejected as an input (input
unlock).
Timecode Processor
(See Figure 1-2.) This function provides for extraction of timecode data from
input video source, and in turn allow individual timecode strings to be
embedded onto the output video. The function can monitor any of the video
inputs of the card for supported timecode formats such as ATC_LTC or
ATC_VITC for down-conversions to HD, and ATC_VITC or VITC
waveform (with selectable odd/even field line number control) for SD SDI or
CVBS inputs. Waveform VITC timecode can also be extracted from a
reference input and used as the output timecode value. If the preferred format
is detected, the preferred format is used by the card; if the preferred format is
not detected, the card uses other formats (where available) as desired. An
internally-generated free-run timecode can be also be embedded on output
video if desired.
The function also provides conversion between various timecode formats and
provides independent insertion and line number controls for each SDI
timecode output format.
When licensed with option
+LTC
, this function also can
receive, send and translate between audio/RS-485 LTC timecode formats and
the VBI formats described above.
