SE4000 MPEG-2 Contribution Encoder Overview
01-0934-401-B 1-3
1.8 ASI Output
An ASI output is also available for connection to an external multiplexer or modulator.
The SE4000 accepts all commonly used video and audio input formats and provides an MPEG-2
DVB compliant transport stream in addition to a DVB
®
-compatible QPSK modulator with a 70
MHz, 140 MHz, and direct L-Band output.
Within the data rate limitations of the channel, the SE4000 can be reconfigured for different video
resolutions, video optimization, and audio compressed bit rates to get the best video
performance. Higher compressed bit rates result in better-decoded video quality.
For high reliability applications, the SE4000 provides exceptional MTBF performance with its
extensive digital processing and proprietary FPGA circuits. In addition, the SE4000 can
automatically configure the video and audio rates in order to match the available transmission
bandwidth for optimum performance.
1.9 Monitor and Control Functions
The SE4000 monitor and control functions include:
•
Fault Relay with passive normally open and normally closed contacts.
•
Front panel operator control utilizing an easy-to-use, intuitive menu and backlit push
buttons.
•
Remote control using either an Ethernet or RS-232 interface.
1.10 Front Panel
The SE4000 front panel interface allows you to scroll through a standard set of menus to easily
set your operating parameters. All configuration and monitoring functions can be efficiently
performed using the front panel.
At-a-glanc e system status can be quickly determined by checking the tri-colored front panel
status LED:
•
Green: indicates that the unit is receiving AC power and that there are no faults.
•
Yellow: indicates that the unit has a current fault.
•
Red: indicates that the unit has a hard fault.
If the Status LED indicates that there is a fault, the Status hot key enables you to go directly to
the current faults list with the press of a button.
1.11 Remote Control
A remote unit, such as a computer terminal, is easily connected to either the EIA-232 remote
control port or Ethernet port allowing the SE4000 to be configured, monitored, and controlled
using character-based ASCII protocol or SNMP.
1.12 Programmable Memory
The SE4000 is a field-deployable unit with non-volatile, field-programmable memory that ensures
retention of configuration parameters during power outages, power off, and transportation. The
SE4000 maintains the last user configuration in flash memory.
