1.2 U4600 Overview
Functional
Description The Wegener Model Unity 4600 Digital Media Receiver/Decoder is a fully
DVB-compliant satellite video IRD. The U4600 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 decom-
pression) 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
•Alarm relay
•Cueing relays and DTMF cue tone outputs standard
•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 U4600 is housed in a standard, 1 RU, rack-mountable chassis. Its front
panel (see Figure 1.1 The Unity 4600 Digital Media Receiver/Decoder) pro-
vides a user interface through six push buttons and an LCD as well as monitor-
ing 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.

TRANSPORT DEMULTIPLEXING
Aggregate MPEG Transport Rate 2.5 to 86.25 Mbps (55 Mbps in Release 1) if not limited by
symbol-rate limits of installed receiver card. This rate is guar-
anteed for reception and transmission to ASI port only. For
local decompression of audio and video, the maximum trans-
port rate remains 55 Mbps.

Stream Padding Minimum of one K28.5 null character padding in inter-byte
gaps, strategy after that is to add equal pad amounts between
bytes before adding extra padding between TS packets
Stream Processing (network-controlled)
Program mapping (routing of incoming program content to up to
16 virtual programs at output) and/or conditional DPI filtering.
