BBG-1002-UDX PRODUCT MANUAL
BBG1002UDX-OM (V1.5)
An internal test signal generator provides a selection of various standard
patterns such as color bars, sweep patterns, and other technical patterns. The
test patterns can be applied to the output video upon loss of input or manually
inserted at any time.
Scaler Function
The scaler function provides up/down/cross-conversion to 3G/HD/SD from
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. Reticule insertion provides
safe action area marking as well as other reticule functions and patterns.
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.
Frame Rate Conversion.
(Option
+FRC
) Linear Frame
Rate Conversion provides conversions between most SD/HD/3G formats –
25/50, 29.97/30/59.94/60, and 23.98/24 (both film and PsF), and also
provides conversions between 50, 59.94, and 60 Hz frame rates. (Figure 1-4
shows the input/output conversions available.) A user FRC Level Control
allows bypassing the FRC for cases where FRC is not needed (thereby
preserving lowest processing latency), or selecting from basic frame rate
conversion (where frames may be duplicated or dropped as required), and
finally three levels of non-dup/drop true conversion where a transitioning
frames is blended from a preceding frame to the subsequent frame.
The aggressiveness levels provide for a subjective balance of detail accuracy
and motion fluidness, where selection of the aggressiveness level can be best
chosen for the type of content.
+FRC
is available as a software option for
devices purchased new and as a field upgrade.
