METHOD FOR DYNAMICALLY ADAPTING VIDEO IMAGE PARAMETERS FOR FACILITATING SUBSEQUENT APPLICATIONS
First Claim
1. Method for adapting an input video stream (V) for facilitating a subsequent application to be performed upon receipt of the adapted video stream by a receiver, said method comprising determining control parameters from quality requirement parameters, bandwidth limitation parameters and spatial parameters, performing a spatial-temporal adaptation of said input video stream in accordance with said control parameters to thereby generate said adapted video stream for provision to said receiver.

Abstract
A method for adapting an input video stream (V) for facilitating a subsequent application to be performed upon receipt of the adapted video stream by a receiver comprises the steps of determining control parameters (AVP) from quality requirement parameters (QR), bandwidth limitation parameters (BW) and spatial parameters (x, y), a step of performing a spatial-temporal adaptation of said input video stream (V) in accordance with said control parameters (AVP) to thereby generate said adapted video stream (AV) for provision to said receiver.
