摘要： A digital television system that includes an RF tuner, a transport stream demultiplexer, an audio decoder, a video decoder, a non-persistent memory, and at least one processor. The non-persistent memory is used to store audio and video packetized elementary stream (PES) packets demultiplexed by the transport stream demultiplexer based upon a broadcast signal received and demodulated by the RF tuner. During the process of decoding and presenting audio, video, and audio-video content on a display device of the television system, the at least one processor generates video records corresponding to each video PES packet and audio records corresponding to each audio PES packet. The video and audio records establish a one to one correspondence between each video PES packet and each audio PES packet and permits each video PES packet and each audio PES packet stored in the memory to be located, decoded, and re-displayed on the display device on the television system.

摘要： A method and system for tracking physical route changes in an optical switching network. One embodiment comprises a method for detecting changes in physical routes of connections within an optical switching network. The method includes receiving an event message from a node of the optical switching network where the event message relates to an event at the node, applying a filtering function to the event message to determine whether the event message may be ignored, ignoring the event message if the event message does not pass the filtering function, and processing the event message if the event message passes the filtering function.

摘要： A system and method involving the compression of palette-based color images. Compression is based upon coding for boundaries that exist in the original uncompressed image, where such boundaries effectively define a character of binary color differentiation between next-adjacent color zones, which differentiation can be expressed as N and not N, where N is one of the colors in the color palette of the original image.

摘要： A computer-implemented method and apparatus for embedding hidden data in an audio signal. An audio signal is received in a base domain and then transformed into a non-base domain, such as cepstrum domain or LP residue domain. The statistical mean manipulation is employed on selected transform coefficients to embed hidden data. The introduced distortion is controlled by psychoacoustic model to ensure the imperceptibility of the embedded hidden data. Scrambling techniques can be plugged in to further increase the security of the data hiding system. The present new audio data hiding scheme provides transparent audio quality, sufficient embedding capacity, and high survivability over a wide range of common signal processing attacks.

摘要： Effective color resolution of a limited-memory color-mapped display system such as a portable liquid crystal display (LCD) handheld video game system can be increased by changing the color mapping information during active display time (e.g., during the horizontal blanking interval between rasterization of successive lines on the display). A subset of the color mapping information can be rewritten during each horizontal blanking period. A full color bitmapped source image can be converted into a color-mapped image in a way that optimizes the use of such color map updates. Since photographic and photorealistic images typically don't exhibit abrupt color changes between neighboring pixels, such techniques can result in display of a color image with very high color resolution (e.g., having as many as 2048 different colors) on hardware intended to permit simultaneous display of only a much smaller number of different colors (e.g., only 56 different colors simultaneously).
