Abstract: Systems and methods that receive a video stream comprising a sequence of plural compressed pictures, wherein the plural compressed pictures comprises a plurality of sets of compressed pictures, wherein each set in the plurality of sets has a respective picture interdependency characteristic, wherein the compressed pictures in the first set depend for decoding only on pictures from the first set.

Abstract: Systems and methods that provide a video stream, the video stream comprising a sequence of plural compressed pictures corresponding to a video program, the plural compressed pictures having plural sets of compressed pictures, each of the plural sets adhering to one or more picture interdependencies, properties, or a combination of the picture interdependencies and properties, and provide auxiliary information in the video stream, the auxiliary information comprising plural data fields, the plural data fields comprising a first data field corresponding to one of multiple possible coding scheme, the coding scheme comprising a set of tiers that uniquely define the one coding scheme, the plural data fields further comprising a second data field different from the first data field, the second data field comprising an indication of whether the one or more picture interdependencies, properties, or a combination of both corresponding to the set of tiers is valid for use in decoding.

Abstract: A JTAG port-sharing device that reduces the required number of hardware pins on an integrated circuit without limiting the integrated circuit testing to a particular debugging platform is provided. The JTAG port-sharing device eliminates the need to have individual hardware pins for each functional block that requires JTAG test interface and allows one set of hardware pins to be shared by a plurality of functional blocks. The JTAG port-sharing device is not limited by a particular debugging platform and allows the use of pre-owned and/or off-the-shelf testing software and/or JTAG debugger devices thereby leading to shorter development cycles and lower development costs.

Abstract: The present invention shows a system for the continuous echo analysis of a body of liquid, surrounded by walls of known dimension, for the presence of an object. Such a system comprises:a transmitting component capable of translating an electrical pulse into intermittent instigative pulses of sonic energy emitted into the body of liquid, wherein such pulses of sonic energy permeate the body of liquid, reflecting off the walls and any object within the body of liquid, and returning as a set of echo information;a receiving component capable of receiving such echo information and translating that echo information into a waveform equivalent of that echo information; and,an analysis component comprising a microprocessor-controlled electronic circuit capable of receiving each waveform and comparing that waveform against stored data on previous waveforms to provide an alarm activation signal when the variance exceeds a predetermined settling.
