  • Patent number: 11212532
    Abstract: A Frame Rate Up-Conversion (FRUC) derivation process, based on frame rate up-conversion techniques, is developed in the reference software JEM (Joint Exploration Model) by the Joint Video Exploration Team (JVET). In one embodiment, a modified FRUC derivation process improves the performances of the current FRUC tool is provided. For example, some candidates of a bi-predictive pair may be discarded initially, which would save signification processing time. The discarding decision may depend on various criteria such as, e.g., a ratio between matching costs of a bi-predictive pair from two reference picture lists, a difference between the matching costs of a bi-predictive pair normalized by their respective template areas.

  • Patent number: 11190749
    Abstract: Stereoscopic images are subsampled and placed in a “checkerboard” pattern in an image. The image is encoded in a monoscopic video format. The monoscopic video is transmitted to a device where the “checkerboard” is decoded. Portions of the checkerboard (e.g., “black” portions) are used to reconstruct one of the stereoscopic images and the other portion of the checkerboard (e.g., “white” portions) are used to reconstruct the other image. The subsamples are, for example, taken from the image in a location coincident to the checkerboard position in which the subsamples are encoded.

  • Patent number: 11184630
    Abstract: Aspects of the disclosure provide a method and an apparatus for video decoding. Processing circuitry of the apparatus decodes prediction information of a current block from a coded video bitstream. The prediction information indicates an inter prediction mode. The processing circuitry calculates at least one hash value based on motion information of a previously decoded block and determines whether the motion information is different from one or more motion information candidates in a candidate list for the current block based on the at least one hash value of the previously decoded block and at least one hash value of each of the one or more motion information candidates. The processing circuitry adds the motion information to the candidate list when the motion information is different from the one or more motion information candidates and reconstructs at least one sample of the current block based on the candidate list.

  • Patent number: 11134259
    Abstract: Video coding systems and methods are described using an enhanced motion compensated picture. In exemplary embodiments, an enhanced motion compensated picture is generated by applying at least one high-pass filter to the motion compensated picture and adding the output of the filter to the motion compensated picture. Coefficients of the high-pass filter are selected by comparing the enhanced motion compensated picture to an original picture. The selected coefficients may be quantized and entropy coded into a bit stream. The high-pass filter may be a cross-plane filter, in which a luma component, which may be an enhanced luma component, is high-pass filtered and the output of the filter is added to at least one of the chroma components to generate an enhanced chroma component.

  • Patent number: 11102510
    Abstract: An improved method of performing intra prediction for encoding or decoding uses interpolation such that substitute samples are found for samples to be used in the interpolation calculation that lie outside a normal reference range. The substitute samples can be repeated end samples from the bottom of a reference portion to the left of the target block, or right samples of a reference portion above the target block. An encoder can signal to a decoder whether to use intra prediction or interpolation prediction.

  • Patent number: 11057649
    Abstract: In certain embodiments, streaming of a live video to trigger-associated recipients in response to triggers in an environment may be facilitated. In some embodiments, one or more triggers may be detected in an environment, and one or more actions associated with the detected triggers may be performed. As an example, where such associated actions include streaming a live video of the environment to one or more recipients, the recipients may be selected as candidates to receive the live video stream based on the recipients being part of a recipient list associated with a detected trigger. In some embodiments, although a first recipient of the recipient list may initially be selected to receive the live video stream, the live video may be streamed to a second recipient of the recipient list based on the first recipient being unavailable to receive the live video stream.
