摘要： A processing system for transmitting digital data, in particular image data, in a transmission channel includes a system for compressing the data, made up of a decorrelator, a quantizer and a coder, and a regulation system receiving as input decorrelated data from the decorrelator and a set point and supplying a quantizing parameter to the quantizer.

摘要： In a method form of the invention, a method for authorizing recording of a telephone communication includes determining if permission has been granted to record a telephone communication in a telephone call. A communication in the telephone call is recorded by a message-recording apparatus for a first caller's telephone responsive to receiving permission for the recording from a second caller's telephone. A key is associated with the recording. The key authorizes transferring the recording to another message-recording apparatus.

摘要： A method for representing a digital image having color values with an extended color gamut in a storage color space having a limited color gamut comprising the steps of: adjusting the color values of the extended color gamut digital image to fit within the limited color gamut to form a limited color gamut digital image; representing the limited color gamut digital image in the storage color space; determining a clipped limited color gamut digital image in which highly quantized regions in the limited color gamut digital image have been clipped; determining a residual image representing a difference between the extended color gamut digital image and the clipped limited color gamut digital image; and associating the residual image with the limited color gamut digital image in the storage color space such that the associated residual image and the limited color gamut digital image in the storage color space are adapted to be used to form a reconstructed extended color gamut digital image.
