Introduction
BBG1022-2FS-OM (V1.3)
Wings Insertion
Wings insertion allows a symmetrical L-R wings insertion to be integrated
into the program video output. Wings video is accommodated using a
separate wings SDI input. The wings user interface displays wings timing
relative to the device output video, allowing wings timing offset to be
adjusted such that wings can be properly framed. (This function does not
provide timing offset control of the wings video; offset must be provided by a
external frame sync card or device controlling the wings video feed.)
Key/Fill Insertion
Option
+KEYER
respective program video, key, and fill inputs. This function provides chroma
keying using the
video that is inserted in the area "cleared out" by the key. The keying user
interface displays key and fill timing relative to the output video, allowing
timing offset to be adjusted such that key and fill can be properly framed.
(The option does not provide timing offset control of the key/fill video; offset
must be provided by external frame sync cards or devices controlling the key
and fill video feed.) The program video input when using keying
accommodates either an SDI or an analog video input; key and fill inputs are
SDI only.
Alpha threshold keyer modes allow full-color key/fill from cost-effective
generic sources such as a standard PC (with appropriate HDMI-to-SDI output
conversion) hosting simple .bmp, .jpeg, or .png graphic files. In these modes,
a common key/fill SDI input provides both the key and fill input.
EAS Text Crawl Generation
automated keying Emergency Alert System (EAS) text crawls in the active
program video output. The function receives its text stream via a card serial
data input. The EAS crawl start can be set to trigger upon receiving the serial
data message, or be set to use a GPI to trigger start of the EAS crawl.
Note: EAS text crawl is available on Path 1 and/or Path 2 program video paths.
However, both crawls will display the same text and attributes (individualized
text massages between the two paths are not supported).
Embedded in the received serial data are commands which set the message
severity to be shown by the keyed crawl (severity is correlated to
user-specified text color and background color for the crawl). User controls
allow control of the crawl speed and repeat of the crawl burn-in (if desired).
Refer to +EAS Manual Supplement OPT-SW-PHXEAS-MS for detailed
information and installation/setup instructions.
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. Line 21 CEA 608
waveform-based SD closed captioning is also supported.
