    Abstract: This disclosure presents techniques for implementing a fast algorithm for implementing odd-type DCTs and DSTs. The techniques include the computation of an odd-type transform on any real-valued sequence of data (e.g., residual values in a video coding process or a block of pixel values of an image coding process) by mapping the odd-type transform to a discrete Fourier transform (DFT). The techniques include a mapping between the real-valued data sequence to an intermediate sequence to be used as an input to a DFT. Using this intermediate sequence, an odd-type transform may be achieved by calculating a DFT of odd size. Fast algorithms for a DFT may be then be used, and as such, the odd-type transform may be calculated in a fast manner

    Abstract: A video coding/decoding system, method and computer program product employ an integer transform matrix for transforming to/from transform coefficients and residual pixel data in moving pictures by a set of semi- orthonormal basis vectors. The basis vectors are derived from conventional DCT or KTL matrixes, but relaxes to some extent the requirements for orthogonality, norm equality and element size limitation. In this way improved coding efficiency and lower complexity compared to previously used integer transforms are possible.

An apparatus comprising an 8-point discrete cosine transform (DCT) hardware unit may implement these techniques to transform media data from a spatial domain to a frequency domain. The 8-point DCT hardware unit includes an even portion comprising factors A, B that are related to a first scaled factor (µ) in accordance with a first relationship. The 8-point DCT hardware unit also includes an odd portion comprising third, fourth, fifth and sixth internal factors (G, D, E, Z) that are related to a second scaled factor (?) in accordance with a second relationship. The first relationship relates the first scaled factor to the first and second internal factors. The second relationship relates the second scaled factor to the third internal factor and a fourth internal factor, as well as, the fifth internal factor and a sixth internal factor.

    Abstract: Die Erfindung bezieht sich auf Signale (beispielsweise Audiosignale), die völlig dem Zufallsprinzip zu unterliegen scheinen, für die jedoch allgemeingültige Aussagen zu treffen sind, etwa in Form von im Mittel zutreffender Parametrisierungen, die nur anhand kurzer Signalabschnitte ermittelt werden können. Anstelle etwa der Simulation eines Gaußschen Prozesses werden beispielsweise Projektionen - auf der reellen bzw. komplexen Zahlenebene gelegener - algebraischer Verknüpfungen dieser Signalabschnitte betrachtet und für diese verblüffend einfache algebraische Invarianten nachgewiesen. Diese Invarianten werden anschliessend als „tags" benutzt, um beispielsweise eine Auswahl gemäss ihrer Häufigkeit vorzunehmen. Im Mittel erweist sich vorliegendes System als effizienter als bislang bekannte Methodologien. Seine praktisch-gewerbliche Anwendung erstreckt sich auf nahezu die gesamte Signalverarbeitung. Im vorliegenden Dokument wird insbesondere auf die stochastische Betrachtung von Audiosignalen eingegangen, wie sie etwa aus dem Bereich Digital Audio Broadcasting bekannt ist.
