—> Modulation schemes such as QPSK transmit multiple bits simultane-
ously. These are referred to as symbols. In addition to the user data
flow which transmits video and audio information, error correction
bits are transferred. The FEC number states the ratio of user bits to
the complete transmitted bits.
