Abstract: A method of decoding an enhanced video stream composed of base layer video access units and enhancement layer video access units, each access unit comprising a plurality of syntax structures, includes passing the syntax structures of the base layer access units to a base layer buffer, passing syntax structures of the enhancement layer access units to an enhancement layer buffer, outputting the syntax structures passed to the base layer buffer in a predetermined sequence, outputting the syntax structures passed to the enhancement layer buffer in a predetermined sequence, and recombining the sequences of syntax structures output by the base layer buffer and the enhancement layer buffer respectively to form a complete enhanced access unit, composed of base layer syntax structures and enhancement layer syntax structures in a predetermined sequence.

Abstract: A system is provided for determining a collocated reference picture to enable encoding and decoding of a current picture for high efficiency video coding (HEVC). The collocated picture is identified by accessing syntax that can include an index for a list0 and a list1, a reference picture set number indicating the number of pictures in list0 and list1, and a flag indicating if the collocated picture is in list0 or list1. The system can further use slice type to determine if both list0 and list1 should be accessed.

Abstract: A call processing module includes a first network interface configured to communicate over a packet-switched network and a second network interface configured to communicate with a local subscriber over a broadband access network employing RF modulation. A call manager is provided which includes a database associating a local subscriber telephone number with an address of a client device associated with the local subscriber for a plurality of subscribers authorized to receive telephony service. A frequency handler is provided for allocating to the client device a receive frequency and a transmit frequency to be used by the client device over the broadband access network during a telephony call.

Abstract: A system is provided for creating level parameter updating codewords for transform coefficients used for relating transform units (TUs) that divide up coding units (CUs) in a High Efficiency Video Coding (HEVC) system. The system provides binarization of the codewords and removes unnecessary operations to reduce system complexity and increase compression performance. The system generates transform coefficients that relate the TUs and begins by providing a parameter variable (cRiceParam) set to an initial value of zero. The parameter variable is then converted into a binary codeword based on the current value of the parameter variable and the value of a symbol and then updated with a new current value after each symbol has been converted. Updating can be provided with reference to table values or the values can be provided from combination logic.

Abstract: In one embodiment, method for decoding a video bitstream comprises: (a) receiving a video bitstream; (b) deriving processed video data from the bitstream; (c) partitioning the processed video data into blocks, wherein each of the blocks is equal to or smaller than a picture; (d) deriving an SAO type from the video bitstream for each of the blocks, wherein the SAO type is selected from the group consisting of one or more edge offset (EO) types and a single merged band offset (BO) type; (e) determining an SAO sub-class associated with the SAO type for each of the pixels in each of the blocks; (f) deriving intensity offset from the video bitstream for the sub-class associated with the SAO type; and (g) applying SAO compensation to each of the pixels in a processed video block, wherein the SAO compensation is based on the intensity offset of step (f).

Abstract: In one embodiment, a method determines a scaled motion vector for a first block. A motion vector for a second block is determined where the motion vector is on a non-uniform motion vector grid. The method then maps the motion vector for the second block to a higher accuracy uniform motion vector grid that is of a higher accuracy than the non-uniform motion vector grid and scales the motion vector for the second block on the higher accuracy motion vector grid. The scaled motion vector is mapped on the higher accuracy motion vector grid to the non-uniform motion vector grid. The scaled motion vector on the non-uniform motion vector grid is associated with the first block for a temporal prediction process.

Abstract: According to the invention, a method for securing a plaintext object within a content receiver is disclosed. In one step, a secure portion of a secure object and a plaintext remainder of the secure object are received. Which portion of the secure object is the secure portion is determined. The secure portion is decrypted to provide a plaintext portion. The plaintext object that comprises the plaintext portion and the plaintext remainder is formed. The plaintext object is stored including authentication and authorization.

Abstract: A portable electronic device has a wireless receiver configured to receive wireless content, a communication interface configured to interface to a docking station having at least one connected media presentation host device, and content reproduction circuitry. The content reproduction circuitry is configured to determine a format required by the media presentation host device and stream the content to the host device through the communication interface in the required format.

Abstract: A method and apparatus for image processing a lens-distorted image (e.g., a fisheye image) is provided. The method includes partitioning coordinate points in a selected output image into tiles. The output image is an undistorted rendition of a subset of the lens-distorted image. Coordinate points on a border of the tiles in the output image are selected. For each tile, coordinate points in the lens-distorted image corresponding to each selected coordinate point in the output image are calculated. In addition, for each tile, a bounding box on the lens-distorted image is selected. The bounding box includes the calculated coordinates in the lens-distorted image. The bounding boxes are expanded so that they encompass all coordinate points in the lens-distorted image that map to all coordinate points in their respective corresponding tiles. Output pixel values are generated for each tile from pixel values in their corresponding expanded bounding boxes.

Abstract: A method and apparatus is provided for annotating video content with metadata generated using speech recognition technology. The method begins by rendering video content on a display device. A segment of speech is received from a user such that the speech segment annotates a portion of the video content currently being rendered. The speech segment is converted to a text-segment and the text-segment is associated with the rendered portion of the video content. The text segment is stored in a selectively retrievable manner so that it is associated with the rendered portion of the video content.
