Abstract: A picture defined in video data is partitioned into blocks that include a luminance (luma) transform block and a chrominance (chroma) transform block. One or more constraints pertaining to the picture are determined from high-level syntax elements and transform skipping of one of both of the luma transform block and the chroma transform block is disallowed if the constraints are not met. The video data are encoded in a bitstream along with an indication that the transform of the luma transform block or the chroma transform block is skipped in response to the transform being skipped.

Abstract: A system includes motion vector prediction circuitry that generates motion vectors for pixel groups and pixel subgroups within the pixel groups. For a current pixel group within the currently processed picture, the motion vector prediction circuitry selects a target reference picture. Without first translating the current pixel group in accord with an offset vector, the motion vector prediction circuitry initiates generation of a default motion vector for the current pixel group. Responsive to the selected target reference picture, the motion vector prediction circuitry generates the offset vector. The motion vector prediction circuitry translates the current pixel group in accord with offset vector and determines motion vectors for pixel subgroups of the current pixel group based on the translated position of the current pixel group.

Abstract: A method of decoding video data includes determining, by a video decoder, a neighboring block in a current frame is inter coded. The method includes, in response to determining the neighboring block is inter coded, determining, by the video decoder, a template for a current block in the current frame based on a partial reconstruction of the neighboring block. The method includes determining, by the video decoder, a reference block in a reference frame corresponding to the template for the current block and determining, by the video decoder, motion vector information for the current frame based on the reference block and the template. The method includes generating, by the video decoder, a predictive block for the current block of video data based on the motion vector information and decoding, by the video decoder, the current block of video data based on the predictive block.

Abstract: A server device obtains, from a primary device associated with a first vehicle, event data concerning an event, video data concerning the event, and/or location data concerning a location of the first vehicle. The server device processes the event data to determine a type of the event, and determines, based on the type of the event and the location data, a proximity zone around the location of the first vehicle. The server device determines additional devices within the proximity zone, where each additional device is associated with a different vehicle. The server device sends, to the additional devices, a message requesting additional video data concerning the event, and obtains the additional video data from at least one additional device. The server device performs, based on relevant event information based on the event data, the video data, and the additional video data, an action concerning the event.

Abstract: The quantization parameters (QP) for Chroma are extended up to and more preferably to the same range as Luma QP (e.g., 0 to 51). Previous, values of Chroma QP only extended up to 39. Techniques are provided for determining extended Chroma QP values (e.g., for Cr and Cb) based on the Luma QP and picture level chroma offsets. In one preferred embodiment, slice level offsets are added making the method particularly well-suited for slice level parallel processing. The extension of Chroma QP enhances functionality, flexibility and friendliness of the High Efficiency Video Coding (HEVC) standard for various applications.

Abstract: A video encoding method includes deriving entry point information specifying an entry point of a substream for a picture. The entry point information includes an offset syntax element when the number of the offset syntax elements is larger than 0, where the offset syntax element represents an entry point offset between two entry points. The entry point information includes a length syntax element when the number of the offset syntax elements is larger than 0, where the length syntax element represents a bits length for the offset syntax element. The offset syntax element represents the number of bytes between the two entry points. A value of the length syntax element plus one corresponds to the bits length of the offset syntax element. A value of the number syntax element corresponds to the number of offset syntax elements in the slice header.

Abstract: The present disclosure provides an automatic correction method and device for a structured-light 3D depth camera. When the optical axis of a laser encoded pattern projector and the optical axis of an image reception sensor change, an offset of an input encoded image relative to an image block in a reference encoded image is acquired, and then the position of the reference encoded image is oppositely adjusted upwards or downwards according to an offset change to form a self-feedback regulation closed-loop system between the center of the input encoded image and the center of the reference encoded image, so that the optimal matching relation can always be figured out when the optical axes of the input encoded image and the reference encoded image change drastically. Furthermore, depth calculation can be carried out according to the corrected offset.
