  • Publication number: 20190182502
    Abstract: Aspects of the disclosure provide methods and a decoder device for video decoding. In some embodiments, the decoder device for video decoding includes processing circuitry. The processing circuitry selects a motion vector of a neighboring sub-block that is a neighbor of a current block under reconstruction. The current block is in a coded picture that is a part of a coded video bitstream. The processing circuitry determines, from the motion vector, motion vector predictors for a plurality of sub-blocks included in the current block. The neighboring sub-block and the plurality of sub-blocks are in a first one of a single row and a single column of the coded picture.

  • Publication number: 20190182496
    Abstract: Aspects of the disclosure provide methods and apparatuses for video decoding. In some embodiments, an apparatus for video decoding includes processing circuitry. The processing circuitry decodes prediction information for a block in a current coded picture that is a part of a coded video sequence. The prediction information is indicative of a merge submode. Then, the processing circuitry constructs, in response to the merge submode, a candidate list of candidate motion vector predictors for the block. The candidate list includes one or more first candidates that are corner neighbors of the block and at least one second candidate that is a side neighbor of the block. Then, the processing circuitry reconstructs the block according to motion information associated with the second candidate.

  • Publication number: 20180322880
    Abstract: Methods, apparatus, and computer readable media are described related to automated assistants that proactively incorporate, into human-to-computer dialog sessions, unsolicited content of potential interest to a user. In various implementations, based on content of an existing human-to-computer dialog session between a user and an automated assistant, an entity mentioned by the user or automated assistant may be identified. Fact(s)s related to the entity or to another entity that is related to the entity may be identified based on entity data contained in database(s). For each of the fact(s), a corresponding measure of potential interest to the user may be determined. Unsolicited natural language content may then be generated that includes one or more of the facts selected based on the corresponding measure(s) of potential interest. The automated assistant may then incorporate the unsolicited content into the existing human-to-computer dialog session or a subsequent human-to-computer dialog session.

  • Patent number: 9787979
    Abstract: Techniques to determine a level id in a layered bitstream are disclosed, such that the same level id can be used for all layers of a scalable bitstream. Also disclosed are techniques to signal level ids for sub bitstreams that can be indicative of lower computational requirements than the level id used for the layered bitstream.

  • Patent number: 9313486
    Abstract: Disclosed are techniques for encoding and decoding layered video where the non-temporal enhancement layers and their respective temporal enhancement layers, comply with a scalable video coding standard or technology, and the base layer and its respective temporal enhancement layers does not comply with the same scalable video coding standard or technology. A Video Parameter Set that comprises information about the relationship of layers includes a syntax element indicative of the derivation mechanism for a temporal layer associated with a NAL unit coded in a first coding technology, for example HEVC. For one value of the syntax element, the derivation mechanism is to set the temporal layer of the base layer NAL unit to the value coded in the header of the encapsulating NAL unit, which can be an HEVC NAL unit. For another value, the derivation mechanism is to imply the value of temporal base layer for the first NAL unit.

  • Patent number: 9141864
    Abstract: The present invention provides techniques for directing the gaze of a subject whose image is captured by a camera, including the direction in which the subject looks, or the distance between the subject and the camera, in such a way that a visually appealing image can be captured by the camera, where a media professional (e.g., an interviewer or a director) or other person knowledgeable in media best practices is non co-located with the subject. The techniques enable the media professional to provide visual hints both manually and automatically to the remotely located subject.

  • Patent number: 9106929
    Abstract: The disclosed subject matter provides techniques for coding overlays in a scalable bitstream environment. H.265's Video Parameter Set (VPS) may be augmented to include syntax elements indicative of a type of an auxiliary picture, which can, for example, be an overlay picture, an overlay layout, an alpha picture (which controls semi-transparency of pictures), and so on. A Supplementary Enhancement Information (SEI-) message may be used to describe the overlay layout and associate the aux type layers.
