1.2 Unity 4600 Overview

Functional
Description

The Wegener Model

Unity 4600

Digital Media Receiver/Decoder is a fully DVB-compliant

satellite video IRD. The

Unity 4600

receives an L-band RF carrier from an external LNB,

demodulates the carrier, extracts the MPEG transport stream, and provides the
decompressed program or programs to DVB-ASI, composite video, and/or stereo audio
outputs.

Features include:

Control by local user or remote COMPEL

®

system

Download of software application upgrades via satellite

Supports COMPEL

®

/CA Conditional Access at transport level or by program

Supports receiver card options using either DVB-QPSK or Advanced Turbo-Modulations

(Turbo-QPSK, T-8PSK, or T-16QAM)

DVB-ASI transport stream output with network-controlled program mapping

Supports ISO 13818-1 transport rates from 2.5 to 55 Mbps (with local decompression) or up

to 86.25 Mbps (to program-mapped ASI transport only)

Local decompression of MPEG-2 video and MPEG-2 (L1 and L2) and/or Dolby AC-3 audio

Auto-recognition and support of 525-line NTSC or 625-line PAL

Audio-only mode option for radio networks

Cueing relays and DTMF cue tone outputs standard (DTMF available only on units built

before 10/07)

Alarm relay

Cueing relays

Optional SCTE 35 DPI message filter for network control of local ad avails

Optional front-panel audio and video monitors

Web browser control

(August 2004)

Physical
Description

The

Unity 4600

is housed in a standard, 1 RU, rack-mountable chassis. Its front panel (see

Figure 1.1

) provides a user interface through six push buttons and an LCD as well as

monitoring through both audio and video ports. The rear panel holds connectors for input
and output signals, LNB power supply, serial and Ethernet monitoring and control, alarm
and user relays, and AC input power. The unit also includes two Unity expansion module
slots.
