Introduction
BBG-1034-AUD-PRO-DSP Functional Description
BBG-1034-AUD-PRO-DSP Functional Description
Figure 1-1 shows a functional block diagram of the
BBG-1034-AUD-PRO-DSP. The BBG-1034-AUD-PRO-DSP includes AES/
analog audio support and CVBS video I/O. In addition to a basic signal
presence input failover function, a Quality Check option allows failover to
alternate inputs or other actions based on user-configurable criteria such as
black or frozen frame. Frame sync and full up-down-cross conversion can be
added as options.
The BBG-1034-AUD-PRO-DSP provides a DSP-based platform that
supports multiple audio DSP options. When optioned with various diverse
audio processing options, the DSP-based processing core (which supports
numerous simultaneous processing engines) uses license “credits” which
allows flexible tailoring of multiple proc function instances.
Note: The BBG-1034-AUD-PRO-DSP DSP base adds support for various DSP
audio options. Specific individual DSP user assets (such as loudness pro-
cessing, upmixing, and Dolby encoders) are activated for use only when cor-
responding option licenses also reside on the device.
BBG-1034-AUD-PRO-DSP Input/Output Formats
The BBG-1034-AUD-PRO-DSP provides the following inputs and outputs:
•
Inputs:
• 3G/HD/SD SDI IN A thru SDI IN D
– four 3G/HD/SD-SDI inputs.
SDI IN A
or
SDI IN B
can be set to failover to
A
or
B
in absence of
opposite channel of this pair.
• CVBS IN –
CVBS coaxial analog video input.
• AES IN –
BNC (AES-3id, 75
Ω
) ports as AES input (number of
ports dependent on model).
•
AN-AUD IN –
Four balanced analog audio embed inputs.
•
Outputs:
•
3G/HD/SD-SDI OUT (1-4)
– four 3G/HD/SD-SDI buffered video
outputs. Each output can be independently set as processed output
video or selected input video reclocked.
•
AES OUT –
BNC (AES-3id, 75
Ω
) ports as AES outputs (number of
ports dependent on model).
• AN-AUD OUT –
Four balanced analog audio de-embed outputs.
• CVBS OUT –
CVBS coaxial analog video usable with SD video
streams.
