9903-UDX-ADDA Functional Description
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. Additionally, user defined and
"Follow AFD Settings" conversion can be applied. User defined settings
allow custom user-defined H and V aspect ratio control. "Follow AFD
Settings" sets the output aspect ratio to track with AFD (Active Format
Description) settings embedded in the received video signal. Reticule
insertion provides safe action area marking as well as other reticule functions
and patterns.
Closed Captioning Processor
This function provides support for closed captioning setup. The function
allows the selection of the ancillary data line number where the ancillary
closed caption data is outputted when the output is HD. When receiving
HD-SDI, both CEA 608 and CEA 708 are supported, with CEA 608 and
CEA 708 (containing CEA 608 packets) converted to line 21 closed
captioning on outputs down-converted to SD.
Color Corrector
Option converts the YCbCr SDI input video to the 4:4:4 RGB color
+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.
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,
bypassing the scaler (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.
