Introduction
9985 Functional Description
Wings Insertion
Option +WINGS allows a symmetrical L-R wings insertion to be integrated
into the card program video output. Wings video is accommodated using a
separate wings SDI input. The wings user interface displays wings timing
relative to the card output video, allowing wings timing offset to be adjusted
such that wings can be properly framed. (The option and its host card 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.)
The wings L/R insertion width can be manually configured, or can be set to
automatically track with aspect ratio as set by the host card (on cards
equipped with aspect ratio control).
Video Output Crosspoint
A four-output video matrix crosspoint allows independently applying the card
video processing paths (
PROGRAM VIDEO , KEY PREVIEW , RECLOCKED ) to
any of the four card discrete coaxial outputs ( SDI OUT A thru SDI OUT D ).
A video D/A converter provides either composite or component analog video
outputs of program video using choices from several formats appropriate for
SD or HD analog video.
Notes: • Rear Module relay bypass is available only between the SDI OUT B and
SDI OUT B ports. This is a passive bypass and does not require card opera-
tion or presence for bypass.
• Output reclocked video can only be obtained from SDI input SDI OUT A .
Audio Subsection Description
Note: Descriptions below include some functions and features that are available
only as options.
(See Figure 1-5.) The 9985 audio processing subsection is built around a card
internal 16-channel bus. This 16-channel bus receives inputs from an input
routing crosspoint that routes de-embedded and discrete AES signals over the
16-channel bus. Correspondingly, at the output end of the 16-channel bus is
an output routing crosspoint that in turn distributes the 16-channel bus signals
to embedded and discrete AES audio outputs.
An Input Audio Status display shows the presence and peak level of each
input audio channel received by the card. For digital audio inputs, payload is
identified (PCM or data such as Dolby
® Digital or E), as well as sample rate
for discrete AES inputs. Discrete AES inputs can have sample rate conversion
applied to align these inputs with the output timing (received sample rates
from 32 kHz to 96 kHz are supported).
