  • Publication number: 20140086331
    Abstract: A device performs a hypothetical reference decoder (HRD) operation that determines conformance of a bitstream to a video coding standard or determines conformance of a video decoder to the video coding standard. As part of performing the HRD operation, the device determines a highest temporal identifier of a bitstream-subset associated with a selected operation point of the bitstream. Furthermore, as part of the HRD operation, the device determines, based on the highest temporal identifier, a particular syntax element from among an array of syntax elements. The device then uses the particular syntax element in the HRD operation.

  • Publication number: 20140079140
    Abstract: This disclosure describes techniques for selection of coded picture buffer (CPB) parameters used to define a CPB for a video coding device for clean random access (CRA) pictures and broken link access (BLA) pictures in a video bitstream. A video coding device receives a bitstream including one or more CRA pictures or BLA pictures, and also receives a message indicating whether to use an alternative set of CPB parameters for at least one of the CRA pictures or BLA pictures. The message may be received from an external means, such as a processing means included in a streaming server or network entity. The video coding device sets a variable defined to indicate the set of CPB parameters for a given one of the pictures based on the received message, and selects the set of CPB parameters for the given one of the pictures based on the variable for the picture.

  • Patent number: 8644757
    Abstract: Methods and systems for coordinating user terminals are disclosed. A user terminal may receive a user terminal identifier and a sensor identifier from a user terminal, determine a group topology based on the user terminal identifier and the sensor identifier to identify a spatial relationship relative to the user terminal, receive a media signal, and identify a subsection of the media signal. The user terminal also may generate subsection information to assign a subsection of the media signal to the user terminal corresponding to the spatial relationship, and may communicate the subsection information to the user terminal.

  • Publication number: 20140003531
    Abstract: This disclosure describes techniques that may enable a video coder to simultaneously implement multiple parallel processing mechanisms, including two or more of wavefront parallel processing (WPP), tiles, and entropy slices. This disclosure describes signaling techniques that are compatible both with coding standards that only allow one parallel processing mechanism to be implemented at a time, but that are also compatible with potential future coding standards that may allow for more than one parallel processing mechanism to be implemented simultaneously. This disclosure also describes restrictions that may enable WPP and tiles to be implemented simultaneously.
