BBG-1022-FS-DSP Functional Description
Figure 1-1 shows a functional block diagram of the BBG-1022-FS-DSP. The
BBG-1022-FS-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-1022-FS-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-1022-FS-DSP DSP base adds support for various DSP audio
options. Specific individual DSP user assets (such as loudness processing,
upmixing, and Dolby encoders) are activated for use only when
corresponding option licenses also reside on the device.

Introduction BBG-1022-FS-DSP Functional Description
Video Processor Description
The BBG-1022-FS-DSP video subsystem provides the functions described
below.
Input Video Select/Quality Check Functions
A GUI-based control allows the device to select from up to four 3G/HD/
SD-SDI inputs, and a SD CVBS analog video input. For analog inputs,
waveform-based ancillary data is preserved for extraction and usage later in
the device processing chain.
The input can be selected using DashBoard manual control, set to failover to
an alternate input upon loss of the target input, and can be externally selected
via a GPIO interface. An input Allowed Rasters and Allowed Frame Rates filter
allows inputs to be filtered (screened) for only user-allowed raster sizes and
frame rates, with unallowed raster/rates being rejected as an input (input
unlock). Reclocked copies of any SDI input can be outputted by the device
when selected as a choice on the output crosspoint.
(Option +QC). Quality Check allows criteria such as black/
frozen frame events to propagate an event alert. This alert can be used by the
Event Setup/actions function to invoke video routing changes, GPO, and
other actions.
Video Output Crosspoint
A four-output video matrix crosspoint allows independently applying the
processed video output or reclocked input to any of the four discrete coaxial
outputs (SDI OUT 1 thru SDI OUT 4). For an SD output, a CVBS coaxial output
is available as a processed video output.
Timecode Processor
(See Figure 1-2.) This function provides for extraction of timecode data from
input video source, and in turn allow individual timecode strings to be
embedded into the output video. The function can monitor any of the video
inputs for supported timecode formats such as ATC_LTC or ATC_VITC for
down-conversions to HD, and ATC_VITC or VITC waveform (with
selectable odd/even field line number control) for SD SDI or CVBS inputs.
Waveform VITC timecode can also be extracted from a reference input and
used as the output timecode value. If the preferred format is detected, the
preferred format is used by the device; if the preferred format is not detected,
the device uses other formats (where available) as desired. An
internally-generated free-run timecode can be also be embedded on output
video if desired.
The function also provides conversion between various timecode formats and
provides independent insertion and line number controls for each SDI
timecode output format.
When licensed with option +LTC, this function also can
receive, send and translate between audio/RS-485 LTC timecode formats and
the VBI formats described above.

1BBG-1022-FS-DSP Functional Description
1-8 BBG-1022-FS-DSP PRODUCT MANUAL BBG-1022-FS-DSP-OM (V1.2)
Figure 1-2 Timecode Processor
Frame Sync Function
Option +FS provides for frame sync control using an external looping
reference signal, or the input video as a frame sync reference.
This function also allows horizontal and/or vertical offset to be added
between the output video and the frame sync reference.
Frame sync can select from either the external frame reference source, or
free-run input video sync. Selectable failover allows alternate reference
selection should the initial reference source become unavailable or invalid. In
the event of input video loss of signal, the output can be set to disable video,
go to black, go to an internal test signal generator pattern, or freeze to the last
intact frame (last frame having valid SAV and EAV codes).
An internal test signal generator provides a selection of various standard
patterns such as color bars, sweep patterns, and other technical patterns. The
test patterns can be applied to the output video upon loss of input or manually
inserted at any time.

Introduction BBG-1022-FS-DSP Functional Description
Video Quality Events Detect Function
Option +QC provides a Video Quality Events user interface and an Event
Triggers user interface for setting an area of concern across the program raster
which can be monitored for frozen or black video events. Threshold controls
allow setting the sensitivity of the function, while engage and disengage
threshold timing controls allow setting how fast the event detection engages
and releases when triggered. The Event Triggers user interface allows
instructing the device as to the action to take upon an event (such as go to a
changed signal routing, activate a GPO, send an automated email, or go to a
user-defined preset).
An Event Triggers user interface can detect Closed Caption Presence and
Closed Caption Absence events. The Event Triggers user interface in turn
allows instructing the device as to the action to take upon an event (such as go
to a changed signal routing, activate a GPO, send an automated email, or go to
a user-defined preset).
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 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.)
The wings L/R insertion width can be manually configured using a wings
width control.
Key/Fill Insertion
Option +KEYER provides for three of the device SDI video inputs to be used
as respective program video, key, and fill inputs. This function provides
chroma keying using the KEY VID IN signal. The FILL VID IN signal provides
the fill 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 and its host BBG-1022-FS-DSP 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.

1BBG-1022-FS-DSP Functional Description
1-10 BBG-1022-FS-DSP PRODUCT MANUAL BBG-1022-FS-DSP-OM (V1.2)
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.
Character Burn-in Functions
User text, video format, and timecode (as selected using the timecode
function) can be burned into the output video. Burn-in attributes such as size,
position, background, color, and opacity are user-configurable. Two discrete
character burn strings can be inserted on output video, with each string
inserted as static text and/or insert only upon LOS. A moving-box insertion
can be enabled to serve as a dynamic raster confidence check even in cases
where the input video image is static or lost.
Trouble Slate Insertion Function
Option +T-SLATE provides for graphic insertion onto the SDI processed
output raster. The function allows for uploading a .png image graphic file to
the card/device memory. (png files are converted to a special format using a
web tool before uploading to the host card/device; this is described in the
setup/operating instructions later in this supplement.)
When the image file(s) is uploaded to the card, its insertion can be enabled via
DashBoard Event Setup controls that enable the graphic insertion only under
certain conditions as desired. (For example, a trouble slate graphic can be set
to insert upon detected input Loss of Signal (LOS).
The trouble slate function allows for positioning the image within the active
video using DashBoard controls. Refer to +LOGO / +T-SLATE Manual
Supplement OPT-SW-PHXLTS-MS for detailed information and installation/
setup instructions.
Ancillary Data Processor
Option +ANC 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
device (Bridge mode), or inserted and/or extracted to and from the device via
serial or IP interfaces connecting to external devices/systems.

BBG-1022-FS-DSP-OM (V1.2) BBG-1022-FS-DSP PRODUCT MANUAL 1-11
Introduction BBG-1022-FS-DSP Functional Description
Audio Processor Description
The audio processor operates as an internal audio router. This function
chooses from the following inputs:
•16 channels of embedded audio from the SDI video input (default
1-to-1 routing to SDI output)
•Up to 16 channels (8 pairs) of discrete AES input1
•Up to 4 channels of balanced analog audio input
(See Figure 1-3.) The audio processing subsection is built around an internal
16-channel audio bus. This 16-channel bus receives inputs from an input
routing crosspoint that routes de-embedded, and discrete AES and analog
audio inputs, over the 16-channel internal 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 and
analog audio outputs.
An Input Audio Status display shows the presence and peak level of each
input audio channel received by the device. In addition to SDI embedded
audio channel sources, analog and coaxial AES inputs are available as input
audio choices. For AES audio inputs, payload is identified (PCM or data such
as Dolby®Digital or E). Each AES input pair has independent sample rate
converters to align each input pair with video timing to accommodate cases
where AES audio is not synchronous with input video (SRC automatically
bypassed for non-PCM payloads). As such, the audio subsection provides a
full crosspoint between all supported audio inputs and output types.

Note: •Clean audio switching is assured only for intentional, controlled switches via
user control. Clean audio switching cannot be assured for failover switches.
•Clean switching requires that both SDI signals (switch from and switch to)
be stable and present, and of the same SDI format and rate.
•Clean audio switching function is designed for PCM audio. This function
does not assure clean decoded audio when switching from/to Dolby or other
non-PCM audio.
Audio Down Mix Function
(See Figure 1-4.) The Audio Down Mixer function provides for the selection
of any five embedded channels serving as Left (L), Right (R), Center (C), Left
Surround (Ls), and Right Surround (Rs) individual signals to be multiplexed
into stereo pair Down Mix Left (DM-L) and Down Mix Right (DM-R). The
resulting stereo pair DM-L and DM-R can in turn be routed to any embedded
audio pair as desired (or de-embedded to an AES or analog audio output).
Figure 1-4 Audio Down Mix Functional Block Diagram with Example Sources
Flex Buses
For both input and output nodes before and after the internal buses, flex buses
provide flexible-structure mixer in which any of 16 summing nodes (Flex Mix
Bus A thru Flex Mix Bus P) can receive any device audio input, thereby
allowing several customizable mixing schemes. Similarly, any of the 16
internal bus signals can be applied to an output flex bus mixer.
Audio DSP Function
The Audio DSP Function 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. Audio proc options include
Dolby®Real-Time Loudness Leveling automatic loudness processing,
Dolby®D/D+ encode/decode, and Linear Acoustic®UPMAX™automatic
upmixing.

BBG-1022-FS-DSP-OM (V1.2) BBG-1022-FS-DSP PRODUCT MANUAL 1-13
Introduction BBG-1022-FS-DSP Functional Description
(See Figure 1-5) The Audio DSP block is positioned between all device audio
inputs (input mixer positioning) as well as audio outputs (output mixer
positioning). Specific individual audio DSP proc functions are facilitated
using licenses for these options. When any audio option is licensed
(activated), the processing can be positioned at the input or output mixer as
desired.
•Input Mixer path positioning locates the DSP pipeline to receive basic
external inputs coming into the device, and then allows DSP
processed output channels to be directed to the internal Audio Bus
channels by selecting Audio DSP channels as sources for destination
Audio Bus channels via the Input Audio Routing/Controls
•Output Mixer path positioning locates the DSP pipeline to receive
Audio Bus channels and then place the DSP processed output
channels directly at the device audio outputs as sources for
destination Embedded Output or AES Output channels via the Output
Audio Routing/Controls.

+DSP Options. Option licenses provide the user-exposed DSP
functions. Available DSP options are as follows. Multiple licenses for the
same or different options can be installed and used simultaneously.
•+DSP-RTLL-5.1 Dolby®Real-Time Loudness Leveling™
5.1-Channel Loudness Processor Option
•+DSP-RTLL-2.0 Dolby®Real-Time Loudness Leveling™
2.0-Channel Loudness Processor Option
Both DSP-RTLL-5.1 and DSP-RTLL-2.0 provide for specially suited
Target Level (which sets the target loudness level) as desired. A Peak
Limit function can be set to provide absolute peak limiting. This
function is also configurable for aggressiveness. An intelligent
Speech Percentage detection algorithm can help distinguish between
program speech and other sounds. This can help in “fine tuning”
various parameters to best suit the program material.

Text-To-Speech
Cobalt Digital +TTS is a complete 21CVAA digital text-to-speech generation /
audio insertion solution for embedded and discrete audio systems. +TTS is
available as a software option for new BBG-1022-FS-DSP units. For field
upgrade, the unit must be returned to the factory for option installation.
+TTS interfaces with industry standard Windows Share folder systems to
receive non-proprietary text, XML, or similar plain text files, and converts
and inserts realistic human-voice audio into user-configured audio channels
(typically an SAP channel pair intended for this playout). +TTS allows for
prioritization based on the organization's discretion (for example, severe
weather alerts out-prioritizing school closings). Alert tones are inserted over
the main program channels to alert the visually impaired that emergency
content is to occur on the SAP channel. Alerts can be played a configurable
number of times, and alerts with higher priority can interrupt current lists for
breaking news. Once the interrupt message is broadcast, +TTS automatically
reverts to normal audio programming. Refer to +TTS Manual Supplement
OPT-TTS-MS for detailed information and installation/setup instructions.
EAS Text Crawl Generation Option +EAS provides for
automated keying Emergency Alert System (EAS) text crawls in the active
program video output. The function receives its text stream via a device 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.
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. This supplement is available
as a download on the Products Download page/tab on the product web page.
Audio Events Detect Function
Option +QC provides a Audio Detect Events user interface and an Event
Triggers user interface for checking user-selected channels to detect audio
silence conditions. The Event Triggers user interface in turn allows instructing
the device as to the action to take upon an event (such as go to a changed
signal routing, activate a GPO, send an automated email, or go to a
user-defined preset).

BBG-1022-FS-DSP-OM (V1.2) BBG-1022-FS-DSP PRODUCT MANUAL 1-15
Introduction BBG-1022-FS-DSP Functional Description
Control and Data Input/Output Interfaces
GPI Interface
Two independent ground-closure sensing GPI inputs (GPI 1 and GPI 2; each
sharing common ground connection as chassis potential) are available.
Associated with each GPI user control is a selection of one of 32 user-defined
presets in which GPI activation invokes a control preset.
Because the GPI closure invokes a user-defined preset, the resulting setup is
highly flexible and totally user-defined. Invoking a user preset to effect a
change involves device setup communication limited only to the items being
changed.
GPI triggering can be user selected to consider the activity on discrete GPI
ports, or combinations of logic states considering both GPI inputs, as well as
be set for level or edge triggering. This flexibility allows multistage,
progressive actions to be invoked if desired. Indication is provided showing
whenever a GPI input has been invoked.
GPO Interface
Two independent phototransistor non-referenced (floating) contact pairs
(GPO 1/1 and GPO 2/2) are available. A GPO can be invoked by setting a GPO
to be enabled when a preset is in turn applied (i.e., when a preset is invoked
(either manually or via event-based loading), the GPO is correspondingly also
activated.
Serial (COMM) Ports
The BBG-1022-FS-DSP is equipped with two, 3-wire serial ports (COM 1 -
Serial Port 1, COM 2 - Serial Port 2). The ports provide for SMPTE 2020
de-embedding to an output port, and provide RS-485 LTC I/O (when licensed
with option +LTC). Either port can be configured as RS-232 Tx/Rx or RS-422
non-duplexed Tx or Rx.
+SCTE104 Insertion
Option +SCTE104 provides generation and insertion of SCTE 104 messages
into baseband SDI. Message send can be triggered from automation GPI or
other event action modes. The option can also execute actions based on SCTE
104 messages received by the device, as well as send triggered SCTE 104
packets to other downstream systems.
The user interface is based on common SCTE 104 operations: Splice Start
Normal, Splice Start Intermediate, Splice End Normal, Splice End
Intermediate, and Splice Cancel (splice_request_data variants), offering full
control of splice start, end, and cancel as well as pre-roll and break duration
offsets. (A Manual Supplement is planned for this option. Please check
product web page.)

1Technical Specifications
1-16 BBG-1022-FS-DSP PRODUCT MANUAL BBG-1022-FS-DSP-OM (V1.2)
Alarm Function
The device can be set to monitor input video/audio for input errors such as
input LOS, frozen or black frame, loss of reference, closed captioning
ancillary data loss, and/or per-channel audio absences. These alarms can be
propagated as a device general error or warning message, and can be
downloaded as basic .txt logs or via a Syslog function.
User setup tables configure the alarm severity escalation as well as trigger
holdoff/release and other thresholds as applicable.
User Control Interface
BBG-1022-FS-DSP uses an HTML5 internal web server for control/
monitoring communication, which allows control via a web interface with no
special or unique application on the client device. Connection to the device to
the network media connection is via a standard 10/100/1000 RJ-45 Ethernet
connection. The device can also be controlled using DashBoard™remote
control, where it appears as a frame connection.
