SYSTEM DESCRIPTION

2. System Description

DigiVu series products are cost effective and space efficient encoding, multiplexing and transmission platforms ideal for digital

simulcast applications, digital delivery of PEG, hub site specific 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.

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 specifically stated. Reference to DVIS is synonymous with DigiVu as these
products run on the same firmware..

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.
