Improved capacity for delivery of digital video via satellite

Affiliate broadcast networks and cable headend systems have unique characteristics that encourage the use of high order modulation and coding for satellite delivery of digital video programming. When these techniques are deployed, there is a dramatic increase in the data rate transferred over the satellite link, and this translates into increased revenue through the delivery of additional program material and other services. These impressive gains in capacity are achieved by employing higher order modulation schemes like 8 PSK and 16 QAM with error correction to boost performance
