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.

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.

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.

Abstract: A system for conditioning digital image data for display of the image represented 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 of different image displaying formats is also stored in a format data table. The digital image data is read from the store, formatted 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: An approach for connection of an antenna employs an antenna including at least one antenna contact; a swivel collar slidably coupleable with the antenna and including at least one collar contact; and an antenna coupler/connector insertable into the swivel collar. The approach may also be characterized as involving moving an antenna by sliding the antenna within a swivel collar, moving an antenna contact at an end of the antenna away from a swivel contact in the swivel collar; and inserting an antenna coupler/connector into the swivel collar including contacting the collar contact with a contact pad on the antenna coupler/connector.

Abstract: Control functions are integrated into the digital signal processing (DSP) chip functioning as the central processor unit (CPU) for the subscriber's cellular telephone unit, eliminating the microcontroller and other support chips. The integration provided is not a physical integration combining the DSP and microcontroller chips into a single chip architecture, but rather a logical (i.e., software) integration. A real time preemptive executive controls the execution of the different functions and the messaging between them. The amount of code that has to run on the DSP chip acting as the CPU is larger than the address space of the DSP chip, so the code memory is divided into banks with only one bank being activated at a time. It is the job of the real time executive to activate the banks as required to control the various functions.
