Abstract
The invention relates to a method of selecting a method from a set of methods of transcoding digital multimedia data, said data being liable to be transferred between at least two communication apparatuses via a communication network, the method comprising the following steps: for each transcoding method, obtaining a distortion value from a mathematical model for establishing the distortion taking into account said transcoding method, the distortion model being applied to information representing digital data, and, selecting a transcoding method as a function of the different distortion values obtained for the set of transcoding methods.

A method for selecting a method from a set of methods of transcoding digital multimedia data, said data being liable to be transferred between at least two communication apparatuses via a communication network, said selection method comprising the following steps:
- for each transcoding method, obtaining a distortion value from a mathematical model for establishing the distortion taking into account said transcoding method, the distortion model being applied to information representing digital data, and,
- selecting a transcoding method as a function of the different distortion values obtained for the set of transcoding methods.
A device for selecting a method from a set of methods of transcoding digital multimedia data, said data being liable to be transferred between at least two communication apparatuses via a communication network, the device comprising:
- for each transcoding method, means for obtaining a distortion value from a mathematical model for establishing the distortion taking into account said transcoding method, the distortion model being applied to information representing digital data, and,
- means for selecting a transcoding method according to the different distortion values obtained for the set of transcoding methods.
