  • Patent number: 9942566
    Abstract: A method and apparatus of predictive Intra coding of a block are disclosed. In one embodiment according to the present invention, a set of Intra prediction modes is determined, and predictive Intra coding is applied to a prediction unit (PU) of an image based on one or more neighboring PUs according to a current Intra prediction mode. The current Intra prediction mode is selected from the set of Intra prediction modes and the current Intra prediction mode is predicted using most probable modes (MPMs) and remaining modes. A number of the remaining modes is kept as a power of 2. For example, the 32 remaining modes can be represented using 5-bit fixed length codes.

  • Patent number: 9936224
    Abstract: A method and apparatus of predictive Intra coding of a block are disclosed. In one embodiment according to the present invention, a same set of Intra prediction modes is used for PUs corresponding to different block sizes including a 4×4 block size and at least one other block size. In another embodiment of the present invention, the number of Intra prediction modes in the set is reduced by removing at least one Intra prediction mode from the set. For example, when the set of 35 Intra prediction modes is used, intraPredMode corresponding to 18, 34, or 26 can be removed. The current Intra prediction mode can be coded predictively based on said one or more neighboring PUs, wherein the current Intra prediction mode is predicted using 2 most probable modes (MPMs) and 32 remaining modes. The 32 remaining modes can be represented using 5-bit fixed length codes.

  • Patent number: 9930371
    Abstract: An entropy decoder is configured to, for horizontal and vertical components of motion vector differences, derive a truncated unary code from the data stream using context-adaptive binary entropy decoding with exactly one context per bin position of the truncated unary code, which is common for horizontal and vertical components of the motion vector differences, and an Exp-Golomb code using a constant equi-probability bypass mode to obtain the binarizations of the motion vector differences. A desymbolizer is configured to debinarize the binarizations of the motion vector difference syntax elements to obtain integer values of the horizontal and vertical components of the motion vector differences. A reconstructor is configured to reconstruct a video based on the integer values of the horizontal and vertical components of the motion vector differences.

  • Patent number: 9918068
    Abstract: A method and apparatus for texture image compression in a 3D video coding system are disclosed. Embodiments according to the present invention derive depth information related to a depth map associated with a texture image and then process the texture image based on the depth information derived. The invention can be applied to the encoder side as well as the decoder side. The encoding order or decoding order for the depth maps and the texture images can be based on block-wise interleaving or picture-wise interleaving. One aspect of the present invent is related to partitioning of the texture image based on depth information of the depth map.

  • Patent number: 9877044
    Abstract: To reduce noise or the like generated at a boundary of tiles introduced in a video coding method. In a motion vector detection unit, a first tile video signal and a second tile video signal included in one picture are supplied to a first detection unit and a second detection unit, and a reference image is supplied from a frame memory to the first detection unit and the second detection unit. The first detection unit performs processing, by inter prediction, on the video signal positioned on or in the vicinity of a tile boundary between a first tile and another tile among many video signals included in the first tile. In this processing, the first detection unit generates a motion vector so as to preferentially refer to the reference image included in another tile different from the first tile among the reference images read out from the frame memory.

  • Patent number: 9870506
    Abstract: Techniques disclosed herein utilize a vision sensor that integrates a special-purpose camera with dedicated computer vision (CV) computation hardware and a dedicated low-power microprocessor for the purposes of detecting, tracking, recognizing, and/or analyzing subjects, objects, and scenes in the view of the camera. The vision sensor processes the information retrieved from the camera using the included low-power microprocessor and sends “events” (or indications that one or more reference occurrences have occurred, and, possibly, associated data) for the main processor only when needed or as defined and configured by the application. This allows the general-purpose microprocessor (which is typically relatively high-speed and high-power to support a variety of applications) to stay in a low-power (e.g., sleep mode) most of the time as conventional, while becoming active only when events are received from the vision sensor.

  • Patent number: 9866831
    Abstract: A method for encoding video is disclosed. The method comprises the steps of receiving information representative of pixels in a current digital image frame of a video to be encoded, calculating a group value for each group of neighboring pixels based on the received information, accumulating group values of corresponding groups of pixels in a first sequence of frames to form a first accumulation of accumulated group values, accumulating group values of corresponding groups of pixels in a second sequence of frames to form a second accumulation of accumulated group values, wherein the second sequence includes frames captured over a longer period of time than the first sequence, comparing accumulated group values of the first accumulation with accumulated group values of the second accumulation, calculating a global change value based on the comparison, setting a GOP length based on the global change value; and encoding the current image frame as an intra-frame or inter-frame based on the GOP length.

  • Patent number: 9858334
    Abstract: A distributed database management system provides a central database resident on a server that contains database objects. Objects, e.g., program guide data, to be replicated are gathered together into distribution packages called “slices,” that are transmitted to client devices. A slice is a subset of the central database which is relevant to clients within a specific domain, such as a geographic region, or under the footprint of a satellite transmitter. The viewer selects television programs and Web content from displayed sections of the program guide data which are recorded to a storage device. The program guide data are used to determine when to start and end recordings. Client devices periodically connect to the server using a phone line and upload information of interest which is combined with information uploaded from other client devices for statistical, operational, or viewing models.
