Abstract: An apparatus and method for decoding of encoded signals representing at least image information from a storage medium is claimed. A storage device (136) is configured to receive the storage medium. A decoder (144) is configured to receive the compressed encrypted encoded signals from the storage medium, and send the signals to a decryptor (320/324). The decryptor (320/324) is configured to decrypt the compressed encrypted encoded signals, and send the signals to a decompressor (320/324). The decompressor (320/324) is configured to receive the compressed encoded signals from the decryptor and to decompress the compressed encoded signals to enable display of the image.

Abstract: An apparatus and method for the detection of errors in compressed digital image is disclosed (Fig.2). In one embodiment, a signature is generated usin g a multiple input shift register and added to the compressed information (210 ). The signature is verified at the decoder to detect an error in the compresse d information. Other information such as the frame number and/or color compone nt type of the compressed image can also be verified to detect errors in the compressed information. In other embodiments, the decoder detects errors if there are bits remaining after decompression and/or if there are invalid cod es at decompression (215). Once an error is detected, the compressed informatio n can be discarded or re-sent and processed. Therefore, the detection of error s can significantly enhance at least the reliance of systems such as digital cinema that require compression of large amounts of data.

Abstract: An apparatus and method for the encoding and storage of signals representing at least image information onto a storage medium is claimed. A source generator is configured to convert the signals into digitized image information. A compressor is configured to receive the digitized image information from the source generator and compress the digitized image. An encryptor is configured to receive the compressed digitized image information from the compressor and encrypt the compressed digitized image information. A storage device is configured to then store the encrypted compressed digitized image information onto the storage medium.

Abstract: A system for conditioning digital image data for display of the image represented (Fig.4) thereby is arranged such that data defining an image is supplied as pixel data and is formatted before being output for display. The pixel data defines a multiplicity of pixels which together form an image and is stored for processing. A set of parameters defining each of a plurality o f different image displaying formats is also stored in a format data table (422). The digital image data is read from the store, formatted (424) depending on the set of parameters for a selected image display format, and output for display of the image represented thereby in the selected image display format.

Abstract: A method of losslessly compressing and encoding signals representing image information is claimed. A lossy compressed data file and a residual compressed data file are generated. When the lossy compressed data file and the residual compressed data file are combined, a lossless data file that is substantially identical to the original data file is created.
