1.4 Summary of Features

1.4.1 MPEG-2 and DVB Compliance

The Modulator normally accepts an MPEG-2 transport stream in either 188-byte or

204-byte packet format when operating in DVB-S/DSNG or DVB-S2 CCM modes.

Alternatively, an internally generated Pseudo Random Binary Sequence (PRBS) or

Null Packets source may be selected for test purposes. This does not require the

presence of a transport stream input.

1.4.2 Data Inputs

The Modulator base unit has two DVB ASI electrical inputs. When operating in

DVB-S/DSNG or DVB-S2 CCM modes, the incoming data may be in any of the

following four formats:

!"188-byte packets (188 data bytes, contiguous packets)

!"204-byte packets (188 data bytes and 16 RS coding bytes; the coding bytes

are ignored)

!"204-byte packets (188 data bytes and 16 dummy bytes)

!"Unframed data, i.e. without MPEG-2 sync bytes

When operating in DVB-S2 ACM mode, the incoming data may only be in

BBFRAME format.

1.4.3 Transport Stream Rate Adaptation

The modulator is capable of performing transport stream rate adaptation with PCR

correction, allowing it to be used at a fixed symbol rate irrespective of the transport

stream input data rate.

1.4.4 IF Output Model

Modulator model SM6630 has a tuneable 50-180 MHz IF output. Both main and

monitor outputs are provided on this model.

1.4.5 L-Band Output Model

Modulator model SM6635 has a tuneable 950-1750 MHz L-band output. Both main

and monitor outputs, and an L-band carrier combining input are provided on this

model. 24 Vdc power and a 10 MHz reference frequency output, both switchable,

are provided via the main L-band output connector for use by an external

frequency up-converter.

SM6630 and SM6635 Satellite Modulators

1.4.6 DVB-S2 and PREKOR Capability

Modulator models SM6630 and SM6635 are both DVB-S2 capable and incorporate

TANDBERG Television’s proprietary PREKOR Dynamic Pre-correction system.

The PREKOR system corrects non-linear magnitude and phase distortions, and

group delay distortion introduced by the uplink HPA and satellite transponder. It is

of particular benefit when using higher order modulations such as 16QAM,

16APSK or 32APSK.

1.4.7 Forward Error Correction Coding

Noise and interference can cause some bits to be received in error. Therefore,

Forward Error Correction (FEC) is used to add redundancy, i.e. extra bits, to the

transmitted signal. This allows a large number of errors at the receiver to be

corrected by the FEC decoder. The FEC coding scheme used depends on the

modulation standard selected. The DVB-S and DVB-DSNG standards employ a

concatenated coding scheme consisting of an outer Reed-Solomon (RS) code, bit

interleaving and an inner convolutional code. The DVB-S2 standard employs a

concatenated coding scheme consisting of an outer Bose-Chaudhuri-

Hocquenghem (BCH) code and an inner Low Density Parity Check (LDPC) code.

Each FEC coding scheme provides for a number of different code rates, permitting

a trade-off between bit-rate and ruggedness.

1.4.8 Modulation Schemes

DVB-S BPSK and QPSK modulations are available as standard on each base unit

model. Additionally, DVB-DSNG 8PSK and 16QAM modulations are available with

the SM66XX/SWO/HOM option. DVB-S2 QPSK, 8PSK, 16APSK and 32APSK

modulations are available as options.

1.4.9 Symbol Rate Range

Each base unit model has a symbol rate range of 0.1 to 5 Msymbol/s as standard.

Extended symbol rate ranges of 0.1 to 48 Msymbol/s and 0.1 to 66 Msymbol/s are

available with the SM66XX/SWO/48MSYM and SM66XX/SWO/66MSYM options,

respectively.

1.4.10 IF Tilt Correction

Both base unit models incorporate a digital IF tilt corrector having a linear

amplitude versus frequency response with user-controllable slope. This facility is

intended for correcting the frequency dependent attenuation that may be

introduced by long IF output cables.

The appropriate software options are required to enable the DVB-S2 and PREKOR functionality.

See Table 1.2: Software Options.
