TE3000 Overview
Video
The TE3000 uses an advanced video compression chip-set which
encodes the input video following the 4:2:0 Main Profile @ Main Level,
according to the MPEG-2 standard (ISO/IEC 13818-2). Compressed video rates
are supported from 1 to 1 5Mbps.
The video encoder features a Tiernan proprietary, high-quality horizontal
resampling filter for intermediate horizontal resolutions.
Audio
Two stereo or four mono audio channels are compressed using MPEG
audio encoding standards.
The TE3000 supports compressed audio output rates of 64 to 384kbps and four
different audio channel compression methods.
Auxiliary Data
Two channels of synchronous data up to 4.096 Mbps each
(RS-422 levels) or asynchronous data up to 38.4 kbps each (RS-232 or RS-422
levels) are supported by the TE3000.
Modulator
The TE3000 has a built-in DVB
®
-compatible QPSK modulator
with a 70 MHz IF carrier capable of supporting up to 20 MSym/sec.
Modulator Control Buttons
The TE3000 provides dedicated modulator
control buttons on the front panel. These are designed to bring carriers up onto
satellites in a fast and efficient manner.
Transport Stream Output
The TE3000 supports both
single-channel-per-carrier (SCPC) and multiple-channels-per-carrier (MCPC)
configurations and can operate in point-to-point or point-to-multipoint
transmission applications.
The TE3000 accepts all commonly used video and audio input formats and outputs
an MPEG-2 DVB compliant transport stream in addition to a DVB-compliant,
QPSK-modulated 70 MHz IF carrier.
If an external transport stream is provided from another encoder, the TE3000 will
multiplex the two transport streams to form a combined transport stream (MCPC).
This daisy chaining of encoders and multiplexing of transport streams may
continue until the units reach the 70 Mbps limit or the modulator symbol rate
limit.
Within the data rate limitations of the channel, the TE3000 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 TE3000 provides exceptional MTBF
performance with its extensive digital processing and proprietary FPGA circuits.
In addition, the TE3000 can automatically configure the video and audio rates in
order to match the available transmission bandwidth for optimum performance.
Monitor and Control Functions
The TE3000 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
