SE4000 MPEG-2 Contribution Encoder Overview
01-0934-401-B 1-1
Overview
1
The SE4000 is a rugged, compact MPEG-2 encoder designed for newsgathering and
professional broadcast applications. Video input may be analog, PAL or NTSC, or serial digital
525/625. Two stereo audio inputs may be either analog or AES/EBU. Video encoding may be
4:2:0 in accordance with MPEG-2 Main Profile @ Mail Level or optional 4:2:2 Studio Profile @
Main Level. The compressed digital output is a DVB
®
MPEG-2 or ATSC-compliant transport
stream. Audio compression may be MPEG, AC-3 2.0, or uncompressed pass-through.
The SE4000 compresses the incoming video with the latest adaptive field-frame MPEG-2
algorithm. The video compression is performed with I, B, and P frames using bi-directional
predictive coding and motion estimation. The two stereo or four mono audio channels are
compressed using either MPEG or AC-3 2.0 audio encoding standard. The two auxiliary data
channels support both synchronous and asynchronous serial formats.
A push button front panel with an illuminated LCD and bright LED indicators provides control and
system status. The optional integrated DVB
®
, QPSK, 8PSK, 16QAM satellite modulator is
controlled by one-touch buttons for carrier on/off and modulate. Additionally, remote control is
available using ASCII or SNMP commands via the EIA-232 remote control and Ethernet ports.
The SE4000’s rugged chassis is a 1U high (4.45 cm), 19” width rack-mount unit providing full rear
panel cabling. The main power switch is conveniently located on the front panel.
