SYSTEM DESCRIPTION
2. System Description
DigiVu series products are cost effective and space efcient encoding, multiplexing and transmission platforms ideal for digital
simulcast applications, digital delivery of PEG, hub site specic programming, local channel insertion or headend encoding.
Several SD/HD baseband programs can be directly encoded/multiplexed and output in QAM or IP format, eliminating the need
for stacking and/or combining several units for multiple program encoding. Models exist with two and six card slots, accepting
various combinations of available cards. HTTP based GUI allows easy set-up and control without the need for proprietary
software installation Remote access and SNMP monitoring are available via integrated RJ45 Ethernet interface.
In this chapter we introduce the key features and describe the attributes that make the DigiVu Device a powerful addition to
any digital cable TV network.

• “Available Input/Output Cards”
2.2 Models Covered by this Guide
There are three models in the DigiVu series, all have QAM output by default, but each has different channel capacity.
FYI: In this guide, reference to DigiVu infers DigiVu 3RU, DigiVu CD 3RU and DigiVu Mini 1RU
unless the model is specically stated. Reference to DVIS is synonymous with DigiVu as these
products run on the same rmware..
2.2.1 DigiVu®3RU
This is the 3RU model with up to 10 channels of SD MPEG-
2 encoding or 5 channels of HD/SD MPEG-2/H.264. The
output is a single QAM. GbE IP output is available but
number of encoded channels is reduced for IP output, as
one card slot is used for the IP output card. This is a popular
model in applications where up to 10SD/5HD channels of
cost effective video are required in commercial sites such as
headends, MDUs, stadiums, hospitals and other health care
facilities where in-house educational channels are implemented.
Distinguishing Features:
• 3RU Chassis.
• 6 card slots for encoders or I/O cards. (Not all slots can be used for all card types.)
• Up to 10 integrated SD MPEG-2 encoded programs using dual encoder cards.
• Up to 5 integrated SD/HD MPEG-2/H.264 encoded programs.

CHAPTER 2: SYSTEM DESCRIPTION
2-2 DigiVu® Series Multichannel MPEG-2/H.264 Encoder/Multiplexer with QAM &/or IP Output - Installation & Operation Manual
2.2.2 DigiVu®CD 3RU
This is very much the same as DigiVu with the addition of an
integrated channel dropping lter. This is a 3RU model with
up to 10 channels of SD MPEG-2 encoding or 5 channels of
HD/SD MPEG-2/H.264 where an existing cable TV channel
lineup requires that a channel be removed before inserting
the new QAM channel. The output is a single QAM. GbE
IP output is available but the number of encoded channels
is reduced for IP output, as one card slot is used for the IP
output card. This is a popular model in applications where up to 10SD/5HD channels of cost effective video are required in
commercial sites such as headends, MDUs, stadiums, hospitals and other health care facilities where in-house educational
channels are implemented.
Distinguishing Features:
• 3RU Chassis.
• Integrated (optional) Channel Dropping Filter.
• 6 card slots for encoders or I/O cards. (Not all slots can be used for all card types)
• Up to 10 integrated SD MPEG-2 encoded programs using dual encoder cards.
• Up to 5 integrated SD/HD MPEG-2/H.264 encoded programs.
2.2.3 DigiVu®Mini 1RU
This is the Mini 1RU model with up to 4 channels of HD/SD
MPEG-2/H.264. The output is single QAM. GbE IP output is
available but the number of encoded channels is reduced for
IP output, as one card slot is used for the IP output IP card.
This is a popular model in applications where up to 4SD/2HD
channels of cost effective video are required in commercial sites such as headends, MDUs, stadiums, hospitals and other
health care facilities where in-house educational channels are implemented.
Distinguishing Features:
• 1RU Chassis.
• 2 card slots for encoders or I/O cards.
• Up to 4 integrated SD MPEG-2 encoded programs using dual encoder cards.
• Up to 2 integrated SD/HD MPEG-2/H.264 programs encoded.
2.3 The DigiVu®Encoder
DigiVu series products are headend or network-edge local content encoding devices for digital video networks. They encode
local baseband analog content into a digital format at the headend or within a property provisioned with digital only TVs, STBs
or DTAs where analog spectrum is not available or where digital content is needed in addition to analog content.
Target applications include:
• Cost-effective encoding, multiplexing & transmission (QAM and/or GigE).
• Headend application of digital simulcast or digital delivery of PEG.
• Hub site specic programming.
• Security or surveillance camera feeds (MDUs, retirement homes).
• Text/character generator or local information channel (hotels, conference centers, gated communities).
• Distribution of ‘in-house’ or private channels throughout a property (e.g., sports stadiums, network studios).
In addition to headend/hub applications, all deployments of digital signals in a modern cable TV system are presented with
challenges which did not exist in the former analog deployments. Specic challenges are faced when MDUs and institutions
within the cable plant require locally inserted content which must be received by the installed base of cable TV set top boxes
(STB). The DigiVu can be used in these properties to encode local analog video cameras, message boards, instructional
and advertising channels into HD/SD MPEG-2/H.264 streams. The resulting stream content may be inserted into a blank EIA
channel or may perform digital drop and insert into pre-existing clear QAM carriers or also perform Add/Drop Multiplexing
within a QAM channel. The exible architecture of the product makes it an ideal candidate for any number of programs that a
headend, hub, MDU or similar property is likely to require.

DigiVu® Series Multichannel MPEG-2/H.264 Encoder/Multiplexer with QAM &/or IP Output - Installation & Operation Manual 2-3
2.4 Key Features
2.4.1 Flexible Digital Program Insertion
Designed for deployment in both RF and IP environments, the DigiVu system is capable of inserting digital programs into an
EIA RF channel where there is no pre-existing carrier or it may be used with an integrated channel deletion lter (DigiVu CD
Model) and any EIA channel may be effectively removed making way for a new QAM created by the DigiVu. The integrated
QAM modulator may be set to any frequency between 54 and 870 MHz (extended range 15 - 975 MHz with some restrictions)
in 1 kHz steps and fully supports STD, IRC and HRC channel plans. For IP distribution/insertion installations, Ethernet transport
streams may be created as either unicast or multicast, MPTS/SPTS with any address within the valid IPv4 address and port
range.
2.4.2 Support for SD/HD MPEG-2/H.264 Encoding
The DigiVu and DigiVu Mini platforms may be ordered with or eld upgraded with card slot plug-in SD or HD video encoders.
Each single channel HD plug-in card may be congured for SD or HD and can encode MPEG-2 or H.264 proles. If SD
programs only will need to be encoded, there are affordable single and dual channel SD encoder cards available. Both SD
and HD programs may be mixed on any output multiplex (IP or QAM) for best bandwidth efciency. Up to 2 HD programs may
be multiplexed to a QAM in the DigiVu Mini platform and up to 5 HD programs on the DigiVu platform. For platforms with IP
outputs, DigiVu Mini may output 1 HD program while the DigiVu may output up to 4 HD programs.
2.4.3 Gigabit Ethernet Output
The DigiVu systems may be provisioned with an optional gigabit Ethernet output card. The Ethernet card has 2 electrical
Ethernet ports (RJ45) as well as 2 SFP ports into which may be installed multimode ber optic SFPs for reliable trunk
connection to distribution switches. A variety of SFP interface types such as single mode and multimode ber are supported
and may be installed as required by system architecture. The Ethernet output may be provisioned to be the sole output of the
unit or simultaneous RF and Ethernet are supported. IP output streams may be provisioned with VLAN tagging and Pro-MPEG
FEC. If congured with IP output only(RF Disabled), then the IP programs may be all SPTS streams.
2.4.4 Integrated Add/Drop Multiplexing
Both DigiVu platforms have integral transport stream multiplexers which creates a new QAM or IP multiplex or alternately
may be used in an add/drop application along with an optional plug-in demodulator card to insert programs into an existing
QAM, clear or encrypted, replacing only the programs that are desired. If the program that is dropped was encrypted, the
replacement program stream will be in the clear. The add/drop application utilizes the QAM demodulator to analyze the MPEG
stream and selectively insert or “drop and insert” local programs in a exible manner.
2.4.5 Remote Monitoring Via SNMP
The product fully supports Simple Network Management Protocol (SNMP) which allows the monitoring of the built in alarm
points by a remote SNMP management console. The available DigiVu MIB may be compiled into the remote Management
Console to provide notication of the triggering of alarms either across a private network or the internet if available. Upon
triggering of a predened alarm, a trap is automatically sent by the DigiVu equipment to a listening SNMP management
console.
2.4.6 Flexible Transport Stream Re-Multiplexing
Flexibility is provided in conguring the re-multiplexed transport stream in an add/drop application. The inserted program may
be assigned any valid PID or MPEG program number and the encoder may be set to any of a wide range of valid CBR video
and audio encoding rates. A built in MPEG-2 stream analyzer (demodulator card required for this feature) for incoming MPEG
programs assists in making the correct selections for replacing programs easy and intuitive. MPEG tables PAT and PMT along
with all PID values are automatically generated to ensure that downstream STB can reliably tune the inserted multiplex and
minimum craft experience is required to implement a system. Dynamic PID monitoring avoids outages due to program table
updates.
2.4.7 Scalable Architecture is Field Upgradable
Encoder cards which accommodate one or two channels of SD MPEG-2 or one channel of HD/SD MPEG-2/H.264 encoding
may be installed as required so the system may be grown as needs grow. Hot swappable cards make upgrading the DigiVu
encoder capability faster while keeping outages to a minimum. The RF Demodulator card may be installed in any available
slot as future requirements dictate even if the initial installation did not originally include it. IP output capabilities may also be
added when required by installing a Gigabit Ethernet card in slots 2 (DigiVu Mini) or 5 (DigiVu and DigiVu CD).
2.4.8 Mass Deployment and Backup with Conguration Export
The DigiVu platforms allow the operator to export the programmed conguration as a le. The exported le may be used for
backup and archive purposes or to allow fast and easy deployment of multiple DigiVu units with similar conguration thus

CHAPTER 2: SYSTEM DESCRIPTION
2-4 DigiVu® Series Multichannel MPEG-2/H.264 Encoder/Multiplexer with QAM &/or IP Output - Installation & Operation Manual
saving the time to manually program each unit before deployment.
NOTE: Care has to be taken not to overwrite the existing DigiVu IP address when loading
exported settings to remote units. This is avoided with factory default settings but may happen with
user congured settings.
2.4.9 IPv4 Network Address Support
All DigiVu platforms support IPv4 IP addressing and maybe congured with any valid IPv4 address to allow access from
private networks or from across the internet. For security against internet intrusion, the DigiVu unit forces assignment of a
username and password which may be changed at any time.
2.4.10 Optional Channel Deletion Filter (DigiVu®CD)
In applications where all cable plant channels have pre-existing QAM carriers, The DigiVu CD may be congured with an
optional channel deletion lter which allows the removal of any EIA channel and all of it’s RF content with minimal adjacent
channel affect, allowing a new QAM channel to be inserted.
2.4.11 Powerful GUI
Management and conguration of the DigiVu system is through a built-in web server which presents the conguration pages
in an intuitive tabbed format interface. Access to the GUI may be congured to allow remotely connecting across any private
network or over the Internet if a connection is made available, usually with a DOCSIS Cable Modem. For internet security, a
username and password provides controlled access against unauthorized persons.
2.4.12 Rack Mounting Enclosure
The DigiVu platform is constructed for deployment in a 19” rack mount installation environment. Integral cooling fans allow
the equipment to be installed and operate in a wide range of uncontrolled environmental conditions where room cooling is not
available.

2.7 Card Slot Numbering
All plug-in cards are installed in a slot on the rear panel which are numbered 1 through 5 plus AUX (6th slot) on the DigiVu and
DigiVu CD, see Figure 2-13, and numbered 1 & 2 on the DigiVu Mini, see Figure 2-14. See the card support table below for
correct card insertion. Be careful to align the circuit board of the card with the internal card guides when re-inserting the cards.
NOTE: The 6th card slot in the DigiVu 3RU platforms is for power only to cards which do not
require management, as this slot does not show up in the GUI. Currently, this slot is exclusively
used for the 2-Way A/V Splitter card but the A/V Splitter card may be installed in any slot if required.
FYI: For information on the way the GUI displays installed cards see “6.5.1 Port Numbering
Convention” on page 6-3.

FIELD APPLICATIONS
3. Field Applications
In this chapter we illustrate some of the common eld applications for the DigiVu systems. This listing is not exhaustive and
does not show every combination of channel or program encoding/insertion. Reference to DigiVu infers all DigiVu platforms
unless a specic model is stated.
FYI: In this guide, reference to DigiVu infers DigiVu 3RU, DigiVu CD 3RU and DigiVu Mini 1RU
unless the model is specically stated. Reference to DVIS is synonymous with DigiVu as these
products run on the same rmware.

• “Summary of Insertion Applications”
• “Analog Channel Insertion vs Digital Channel Insertion”
• “QAM Insertion Without Decoding”
• “Insertion Into Under-utilized QAM (Add/Drop)”
• “IP Video Content Insertion”
• “Local Content Back Haul Over IP”
3.2 Summary of Insertion Applications
3.2.1 Insertion of a Carrier Into a Blank or Empty Channel Spectrum
It is possible to insert the DigiVu QAM carrier into spectrum space left intentionally blank without the use of a channel deletion
lter. Generally the two scenarios for insertion are in between existing adjacent system channels and at the upper edge of the
cable system passband.
See “QAM Insertion Without Decoding” on page 3-3
3.2.2 Insertion of a Carrier with use of a Deletion Filter to Remove an Existing Carrier
Using the optional channel deletion lter, the target system channel may be effectively removed to make space for the inserted
channel. In this case, adjacent system channels are minimally affected through the DigiVu “Brick Wall” channel dropping lter
technology.
See “Insertion into Locally Deleted QAM” on page 3-4
3.2.3 Digital Program Insertion into an Existing QAM with Existing Programs
This application is intended for ‘in the clear’ or encrypted QAM channels that have programming that is able to be sacriced
or for QAM channels that are designed for this program insertion feature. Encrypted programs will be replaced with an ‘in the
clear’ program.
See “Insertion into Under-utilized QAM (Add/Drop)” on page 3-4
3.2.4 IP Video Content Insertion
This application uses the DigiVu encoding capability with IP output to locally insert programming into an IPTV property or
remote hub for distribution or Headend encoding application.
See “IP Video Content Insertion” on page 3-5
3.2.5 Video Back Haul Schemes
These applications uses the DigiVu encoding capability with IP output, QAM output to haul a special remote origination
program to a hub for distribution.
