    Abstract: A Class-D audio amplifier includes a triangular wave generator, a wave reshaping device and a pulse-width modulator. The triangular wave generator generates a first triangular wave. The wave reshaping device generates a second triangular wave by reshaping the first triangular wave. The pulse-width modulator modulates a pair of differential audio input waves with the second triangular wave instead of the first triangular wave to reduce a switching loss of the Class-D audio amplifier.

  • Publication number: 20250193451
    Abstract: A video coder receives data for a block of pixels to be encoded or decoded as a current block of a current picture of a video. The video coder receives a set of transform coefficients of the current block. The video coder identifies multiple transform hypotheses. Each hypothesis includes two or more predicted transform parameters. The video coder computes a cost for each hypothesis by performing inverse transform on the transform coefficients of the current block according to the predicted transform parameters of the hypothesis. The video coder signals or receives a codeword that identifies a first transform mode of a first transform parameter. The codeword is assigned to the first transform mode based on the calculated costs of the multiple transform hypotheses. The video coder encodes or decodes the current block by reconstructing the current block according to the identified first transform mode.

  • Publication number: 20250193394
    Abstract: A method for signaling arbitrary partition boundaries is provided. A video coder derives a partitioning structure for splitting the current block by identifying a partitioning position having a lowest cost. The video coder splits the current block into first and second partitions according to the identified partitioning position. The video coder encodes or decodes the first and second partitions of the current block. The first and second partitions may be associated with first and second templates that are constructed based on reconstructed pixels neighboring the current block. The video coder may identify the partitioning position by computing a first cost based on the first template and a second cost based on the second template and optimizing the partitioning position to minimize a sum of the first and second costs.
