Abstract

Utilizing multiple distortion measures. A first distortion measure for at least one packet is received. A second distortion measure for the at least one packet is received, wherein the second distortion measure is different than the first distortion measure. A processing operation is performed based at least in part on the first distortion measure and the second distortion measure.

Claims

1. A method for utilizing multiple distortion measures, said method comprising:

receiving a first distortion measure for at least one packet;

receiving a second distortion measure for said at least one packet, wherein said second distortion measure is different than said first distortion measure;

performing a processing operation based at least in part on said first distortion measure and said second distortion measure, wherein said performing a processing operation based at least in part on said first distortion measure and said second distortion measure comprises using said first distortion measure and said second distortion measure for adapting processing of packet transmission;

determining a first resolution packet transmission schedule corresponding to the first distortion measure;

determining a second resolution packet transmission schedule corresponding to the second distortion measure;

filling a multiple rate packet transmission schedule according to said first resolution packet transmission schedule until a changing rate is detected; and

responsive to detecting said changing rate, filling a remainder of said multiple rate packet transmission schedule according to said second resolution packet transmission schedule.

2. The method of claim 1 further comprising:

generating a multiple rate packet transmission schedule based at least in part on said first distortion measure and said second distortion measure, wherein said multiple rate packet transmission schedule is for ordering packet transmission at said plurality of data rates.

3. The method of claim 2 wherein said multiple rate packet transmission schedule is an embedded multiple rate packet transmission schedule.

4. The method of claim 1 wherein said multiple rate packet transmission schedule is an embedded multiple rate packet transmission schedule.

5. The method of claim 1 further comprising:

determining a changing rate for minimizing integral distortion.

6. The method of claim 1 wherein said filling a remainder of said multiple rate packet transmission schedule according to said second resolution packet transmission comprises:

determining whether a scalably coded packet is missing from said second resolution packet transmission schedule;

if a scalably coded packet is missing from said first resolution packet transmission schedule, filling said multiple rate packet transmission schedule with said scalably coded packet from said first resolution transmission schedule; and

switching to said second resolution transmission schedule once said multiple rate packet transmission schedule is filled with said scalably coded packet from said first resolution transmission schedule.

7. The method of claim 1 wherein said first resolution packet transmission schedule is a low resolution packet transmission schedule and wherein said second resolution packet transmission schedule is a high resolution packet transmission schedule.
