CA 2233213
A transmitting system for transmitting an RF signal comprises: means for receiving a data signal containing encoded audio data and video data, said signal including therein a first clock signal; data recovery means for recovering the first clock signal from the data signal; a data randomiser for altering the order of data within the data signal; an encoder to encode the randomised data signal in accordance with a specified encoding scheme; a trellis encoder to trellis encode the encoded data signal; a pulse shaping means to constrain the trellis encoded data signal within a fixed bandwidth; pilot signal means for adding a pilot signal to the constrained data signal; upconversion means for upconverting the constrained data signal and pilot signal to a channel frequency; amplifier means for amplifying the upconverted data signal and pilot signal; and broadcasting means for transmitting the amplified signals.
