Patent ID: 7457312

Claim:
A method comprising: assigning a bandwidth in a streamable content; and transmitting a modulated data signal having data fields encoded thereon transmitted over a communications channel having the assigned bandwidth, said modulated data signal representing the streamable content, said assigned bandwidth specifying a bandwidth based on a first bandwidth for transmitting the entire data fields of the modulated data signal, said data fields comprising data encoded in the data fields in the streamable content representing a combined stream including a first stream having the first bandwidth and including a second stream having a second bandwidth, wherein the first stream represents a first portion of the streamable content and the second stream represents a second portion of the streamable content, wherein the first bandwidth is greater than the second bandwidth, wherein the first stream is transmitted simultaneously with the second stream, wherein, during certain periods of time, the combined stream consists primarily of either the first stream or the second stream but not both so that during the certain periods the combined stream has a bandwidth which is less than or equal to the first bandwidth, and wherein the assigned bandwidth of the communications channel allocated to the combined stream is less than or equal to the first bandwidth.
