Introduction
BBG-1034-AUDPRO-OM (V1.1)
Scaler Function
Option
provides up/down/cross-conversion to 3G/HD/SD from
+UDX
multiple SD and 3G/HD video formats and multiple frame rates, and
cross-conversion between interlaced and progressive formats, with
auto-format detect/down-conversion of SMPTE 424M/292M/259M formats.
The scaler function also provides aspect ratio conversion that provides a
choice from several standard aspect ratios. User-defined settings allow
custom user-defined H and V aspect ratio control. The scaler provides special
modes that allow de-interlacing to be bypassed in certain cases to reduce
processing latency. Also provided are selections to optimize 3:2 pulldown
conversion where timecode or other timing references can be relied upon to
indicate frame transitions.
Timecode Processor
(See Figure 1-3.) This function provides for extraction of timecode data from
input video source, and in turn allow individual timecode strings to be
embedded into the output video. The function can monitor any of the video
inputs 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 device; if the preferred format is not detected,
the device 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
receive, send and translate between audio/RS-485 LTC timecode formats and
the VBI formats described above.
