Patent ID: 8117638

Claim:
A method comprising: using a transmitter to simultaneously transmit a first set of two or more multimedia streams within a first range of frequencies selected from a spectrum of frequencies, the first set of multimedia streams comprising digitally encoded video content, said first range of frequencies being the range to which a legacy group of multimedia receivers are capable of tuning, wherein said video content of said first set of multimedia streams is reconstructable for rendering on a display device by said legacy group of multimedia receivers with reference only to said first range of frequencies; and simultaneously transmitting a second set of two or more multimedia streams within a second range of frequencies selected from the spectrum of frequencies concurrently with said first set, the second set of multimedia streams comprising said digitally encoded video content, said second range of frequencies being the range to which an alternate group of multimedia receivers are capable of tuning, wherein said video content of said second set of multimedia streams is reconstructable for rendering on a display device by said alternate group of multimedia receivers with reference only to said second range of frequencies; wherein said second frequency range comprises a larger bandwidth than a bandwidth of said first frequency range; wherein said second range of frequencies comprises a 30 MHz bandwidth and said first range of frequencies comprises a 6 MHz bandwidth.
