Patent number: 12225198Abstract: A block-based decoder is configured to partition a picture of more than one color component and of a color sampling format, according to which each color component is equally sampled, into blocks using a partitioning scheme in which the picture is equally partitioned with respect to each color component. A first color component is decoded in units of the blocks with selecting, for each of intra-predicted first color component blocks, one out of a first set of intra-prediction modes. The first set comprises matrix-based intra prediction modes according to each of which a block inner is predicted by deriving a sample value vector out of neighboring reference samples, computing a matrix-vector product between the sample value vector and a prediction matrix associated with the respective matrix-based intra prediction mode to obtain a prediction vector, and predicting samples in the block inner on the basis of the prediction vector.Type: GrantFiled: April 1, 2021Date of Patent: February 11, 2025Assignee: Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V.Inventors: Jonathan Pfaff, Tobias Hinz, Philipp Helle, Philipp Merkle, Björn Stallenberger, Michael Schäfer, Benjamin Bross, Heiko Schwarz, Detlev Marpe, Thomas Wiegand

Publication number: 20240430922Abstract: Short-term fading can be addressed through channel hopping mechanisms in the time scale of few milliseconds. Existing do not address short-term fading. For example, Wi-Fi channel change mechanisms take several 100 ms to perform a channel change. Short-term fading lasts around 80 ms and those methods would not detect or solve issues with missing packets at this speed. The present disclosure proposes a novel method where, a computer and all other devices, e.g., a game console and game controllers, switch channels every 8 to 16 ms through a pre-agreed upon channel sequence. Thus, even if one of the channels is undergoing a deep fade, the controllers/console will be able to leverage other channels to minimize packet loss rates.Type: ApplicationFiled: June 23, 2023Publication date: December 26, 2024Inventors: Krishna Kant CHINTALAPUDI, Joseph Michael Schaefer, Gopala Sri Hari Narlanka, Hao Yin
