Patent ID: 7532672

Claim:
A method of processing a multimedia signal containing an information content, said method comprising: receiving said multimedia signal; generating a first bit stream and a second bit stream from said multimedia signal; sending said first bit stream on a first channel and said second bit stream on a second channel to a receiver system, wherein said first channel and said second channel represent corresponding separate channels of a packet network, wherein said first bit stream represents said information content with a first quality level, and wherein said second bit stream in combination with said first bit stream enables said information content to be represented with a second quality level, said second quality level being greater than said first quality level, wherein said first channel transfers said first bit stream with a first plurality of Quality of Service (QoS) parameters and said second channel transfers said second bit stream with a second plurality of QoS parameters, wherein said first plurality of QoS parameters are not identical to said second plurality of QoS parameters.
