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 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.

CPC classification number: H04N19/89 , H04N19/625
Abstract: An apparatus and method for the detection of errors in compressed digital image is disclosed. In one embodiment, a signature is generated using a multiple input shift register and added to the compressed information. The signature is verified at the decoder to detect an error in the compressed information. Other information such as the frame number and/or color component 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 codes at decompression. Once an error is detected, the compressed information can be discarded or re-sent and processed. Therefore, the detection of errors can significantly enhance at least the reliance of systems such as digital cinema that require compression of large amounts of data.
