Transport Stream Input

The main input of the TT1220 is the QPSK f-connector, located on the rear
of the unit. This input interfaces directly to Low-Noise Block (LNB) and
accepts an intermediate frequency (IF) input in the 950 – 2150 MHz
(L-band) range. The unit can provide DC power, that may be used for
polarisation switching on the LNB, as well as a 22 kHz control signal. The
maximum input symbol rate is 44,5 Msym/s, while the maximum total
bit-rate is 60 Mbit/s.

An optional (factory fitted) DVB-ASI BNC connector may be present,
replacing the QPSK f-connector. This input accepts a DVB-ASI compliant
signal (188 or 204 byte), at a maximum of 60 Mbit/s.

Instruction Manual: Professional Receivers and Decoders (IRD) Page 1-5
ST.TM.TT1220.1

Introduction

1.2.3 Outputs

Transport Stream Output

One DVB-ASI BNC connector may be avail a ble. This provides the current
incoming transport stream, including the current descrambled service, to
be output at a maximum of 60 Mbit/s.

Video Outputs

Two BNC composite analogue video outputs are p r esent on the rear of the
unit. If the factory fitted option of a SDI video output is p resent, it
replaces one of the composite outputs.

Audio Outputs

One analogue stereo audio pair carried on a 9-pin D-SUB connector, is
available. Depending on the input, it is menu configurable to allow one
stereo, a dual-mono or two independent mono channels. The channels can
carry different languages.

The primary audio output might be replaced by the extended audio output
option, which allows for two stereo audio pairs carried on two 9-pin D-SUB
connectors.

Depending on the configured options, the extend ed audi o outp ut may be
able to either provide analogue balanced audio, AES/EBU digital audio,
AC-3 digital passthrough, or AC-3 to analogue Dolby Pro-Logic downmix.
