Abstract
A method for efficiently transmitting several multimedia streams to one or more multimedia receivers comprises transmitting a first plurality of channels within a first plurality of frequency blocks having a first frequency range, said first frequency range being the range to which a legacy group of multimedia receivers are capable of tuning; and simulcasting said first plurality of channels within one or more alternate frequency blocks having an alternate frequency range, said alternate frequency range being the range to which an alternate group of multimedia receivers are capable of tuning.
