ABE SOLUTION FOR BACKHAULING
AND CONTRIBUTION IN TELEVISION BROADCASTING:
LINK PERFORMANCES
Occupied bandwidth (channel):
According to symbol rate and roll-off factor settings (up to 40MHz)
Transport stream bit-rate (Link capacity):
According to modulation scheme, code rate, symbol rate, etc. (up to over 100Mbit/s)
Receiver minimum input signal:
According to modulation scheme, code rate and symbol rate (up to less than −90dBm)
Example 1:
With 14.8MS/s, 35% roll-off, 7/8 code rate, DVB-S QPSK modulation scheme, the net input
bit-rate (Transport Stream bit-rate / Link information capacity) is 23.9Mbit/s, enough to accommodate four Video/Dual-Audio programs with excellent broadcast quality, in the same
occupied bandwidth (around 20MHz) of an analog TV microwave link and with a receiver
threshold of around -90dBm.
Example 2:
With 16MS/s, 25% roll-off, 3/4 code rate, DVB-S2 8PSK modulation scheme, the net input
bit-rate (Transport Stream bit-rate / Link information capacity) is up to 34.8Mbit/s in the same
occupied bandwidth (around 20MHz) of an analog TV microwave link and with a receiver
threshold of around -90dBm.
Example 3:
With 23.3MS/s, 20% roll-off, 9/10 code rate, DVB-S2 32APSK modulation scheme, the net
input bit-rate (Transport Stream bit-rate / Link information capacity) is up to 101.5Mbit/s in an
occupied bandwidth of a standard Link (28MHz) with a receiver threshold of around -80dBm.

MAIN BENEFITS

USE OF THE MOST ADVANCED STANDARD (DVB-S2) FOR BACKHAULING AND CONTRIBUTION IN TELEVSION BROADCASTING
o
o
o

NO proprietary modulation schemes and FEC codes (DVB-S2 modulation
schemes up to 32APSK are employed)
NO proprietary aggregation systems - The aggregation of the Transport Streams
(up to #6) is made employing the DVB-S2 MULTISTREAM mode
NO proprietary encryption: DVB-S2 Physical Layer scrambling implemented
EFFICIENT USE OF THE ELECTROMAGNETIC SPECTRUM
o
o
o
No overhead for encapsulation to carry multiple Transport Streams
Very high efficiency Forward Error Correction Codes (LDPC + BCH)
No fixed capacity: parameters (bandwidth, FEC codes, etc.) are optimized in order
to obtain the best performance according to the available bandwidth and needed
capacity
