Scaler Function
The scaler function provides path 1/2 independent 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. Both paths have independent de-interlacers which can for auto
or manual enable. De-interlacing, when converting an interlaced input to a
progressive output, can reduce the chance of artifacts or jittering when, for
example, content consists of fast-motion paused scenes.
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 (default mode auto-detects
interlaced program and performs de-interlace). Also provided are selections
to optimize 3:2 pulldown conversion where timecode or other timing
references can be relied upon to indicate frame transitions.
Color Corrector
Option
+COLOR
converts the YCbCr SDI input video to the 4:4:4 RGB color
space (where the color correction is applied), and then back to YCbCr SDI on
the output. Controls are available to adjust each RGB level independently for
both white levels (gain) and black levels (offset). Gamma can also be
independently adjusted for each RGB channels. Various controls can be
ganged to provide adjustment for all three color channels simultaneously.
Color correction can be independently applied to either path.
Ancillary Data Processor
This function provides full VANC/HANC ancillary data de-embedding and
embedding for 3G/HD/SD-SDI streams. Direct access to DID and SDID
locations allows extraction or insertion of user data such as camera PTZ,
SCTE 104, closed-captioning read/insert, GPI/GPO via ANC, or other
specialized user payloads. Data can be extracted and inserted within the card
(Bridge mode), or inserted and/or extracted to and from the card via serial or
IP interfaces connecting to external devices/systems. A rear I/O module with
a dedicated IP port can be used with the ancillary data processor function for
data insertion or extraction via IP.
Video Output Crosspoint
Used in common as a routing source for both
Path 1
/
Path 2
is a four-output
video matrix crosspoint that allows independently applying the card
processed video output, reclocked input, or wings/key-fill previews to any of
the four card discrete coaxial outputs (
SDI OUT 1
thru
SDI OUT 4
).
