Abstract:
A method (900) of losslessly compressing and encoding signals representing image information is claimed. A lossy compressed data file (922) and a residual compressed data file (960) are generated. When the lossy compressed data file and the residual compressed file are combined, a lossless data file that is substantially identical to the original data file is created.
Abstract:
An apparatus and method for decoding of encoded signals representing at least image information from a storage medium is claimed. A storage device is configured to receive the storage medium. A decoder is configured receive the compressed encrypted encoded signals from the storage medium, and send the signals to a decryptor. The decryptor is configured to decrypt the compressed encrypted encoded signals, and send the signals to a decompressor. The decompressor is configured to receive the compressed encoded signals from the decryptor and to decompress the compressed encoded signals to enable display of the image.
