Abstract: Disclosed are methods and apparatus for composing and communicating Digital Composition Coded Multisensory Messages (DCC MSMs). The present invention also relates to the design, composition, creation, and communication of the multisensory messages. Multisensory messages, while rich in content and meaning, are to be composable from a great variety of platforms, from cell phones to mainframes.

Abstract: A reconstruction system for digital signals processed by the laplacian pyramid including a master lifting-based parameterization reconstruction scheme. The system also involves the design of low-complexity FIR linear-phase integer-coefficient filtering operators for lapacian pyramid decimation and interpolation stages that deliver a minimum mean-squared error reconstruction.

Abstract: A system and method are provided for a highly compact apparatus, instantiated in software firmware, or in a hardware circuit board, whose purpose is multimedia encoder processing; a secondary apparatus, whether instantiated in software, firmware, or hardware, residing in either the same or an external system, for the purpose of providing a graphical user interface, a resource for data packaging, or for streaming; and a third apparatus, also in software, firmware or hardware, for receiving, decoding and displaying the received signal.

Abstract: A transform-based image compression framework called local zerotree (LZT) coding partitions the transform coefficients into small groups, each of which is encoded independently using popular zerotree algorithms. The LZT coder achieves similar coding performances as current state-of-the-art embedded coders. The advantage of this coding method is fourfold: (i) because of the reduction of memory buffering, LZT reduces the complexity of the codec implementation and increase the speed of the zerotree algorithm significantly, especially in hardware; (ii) LZT processes large images under limited memory constraint; (iii) LZT supports parallel processing mode as long as the transform in use has that capability; and (iv) LZT facilitates the coding/decoding of regions of interest. The penalty in coding performance is minute compared to global zerotree predecessors in that there are only a few extra bytes of side information.
