Abstract
A method for formatting broadcast data for transmission on an uplink carrier to a satellite is provided which combines data streams from a number of service providers into parallel streams on uplink carriers to allow for efficient and economic use of the space segment. Bits in a program are assembled into a first number of prime rate increments having uniform and predetermined rates. A frame having a predetermined duration is generated which comprises each of the prime rate increments and a frame header. The frame is divided into symbols, each of the symbols comprising a predetermined and consecutive number of the program bits. The symbols are demultiplexed into a second number of parallel prime rate channels, with the symbols being provided in ascending order across the prime rate channels so as to separate consecutive symbols. The prime rate channels each comprise a prime rate channel synchronization header for recovering the prime rate channels at said remote receiver units. The prime rate channels are then demultiplexed onto a corresponding number of uplink carrier frequencies for broadcast transmission.
