Edje 2000 Hardware

Introduction

Thank you for purchasing Adtec’s Edje-2000. The Edje-2000 is a new
revolutionary Real Time MPEG 2 Streaming Encoder designed for IP
and optionally DVB-ASI distribution applications. It represents a
revolutionary enhancement for real time encoding applications that
require high reliability and broadcast quality without requiring a large
budget. This amazingly small MPEG 2 encoding appliance provides real
time encoding, multiplexing and distribution without the use of a PC. The
IP output is intended to be Uni-cast or Multi-cast to Adtec Edje-1010 or
Edje-1013 Network MPEG Decoding Appliances or desktop MPEG
decoding applications. The DVB-ASI output option is targeted to digital
television (DTV) applications including distribution via Satellite QPSK
modulation, Cable QAM modulation and Terrestrial COFDM or 8VSB
modulation (modulator not included).
