  • Patent number: 12250386
    Abstract: This disclosure provides methods, devices, and systems for video compression. The present implementations more specifically relate to video compression techniques that account for spatial-temporal changes in pixel values. In some aspects, an encoder may determine a change importance factor (CIF) for each image tile of a current image to be encoded. The encoder may calculate the CIF for an image tile of the current image (the “current image tile”) based on a degree of variation among the pixel values in the current image tile, a degree of change between the current image tile and a respective image tile of a previously-encoded image (the “previous image tile”), and a degree of variation among the pixel values in the previous image tile. In some implementations, the encoder may determine whether to transmit each of the current image tiles to a receiving device based on the CIF associated with the respective image tile.

  • Patent number: 12244800
    Abstract: To encode a picture, a coding tree unit (CTU) in the picture is partitioned by a quadtree structure, and the quadtree leaf nodes can be further partitioned by a multi-type tree (MTT) structure. To increase the set of reachable coding tree nodes and leaves, we propose to increase the maximum allowed MTT hierarchy depth to be twice the difference between the CTU size and the minimum allowed size for a CU. The maximum allowed MTT hierarchy depth can be specified for all QT levels in order to provide more flexibility in the split tree. Alternatively, only two levels of maximum allowed MTT depth are signaled: one when QT splits are allowed, and another one when no more QT splits are allowed. In addition, an upper bound can be set for the minimum allowed coding block size, based on the coding tree unit size or the maximum allowed transform size.

  • Patent number: 12067151
    Abstract: A computer with data (the “source”) establishes communication channels to other computers with available computing resources (the “workers”). The computers exchange information to negotiate alternative sets of encryption techniques and security settings. The source calculates a response by negotiating a data reduction scheme that is applied to form heterogeneous data payloads. Some of the data are encrypted using a fully homomorphic encryption algorithm to form a multi-segment response, whereas other data are encrypted using an encryption algorithm other than fully homomorphic encryption. Security-relevant parameters of the invoked encryption schemes are varied to achieve a negotiated optimal data reduction scheme. Candidate reduction schemes to apply to the user data are negotiated based on then-current communication bandwidth availability and/or computer processing resources at the source and/or at the workers.
