  • Patent number: 8428149
    Abstract: A structure outputting a decoded video stream includes a processing block and a range modification circuit. The processing block decodes an input stream to generate and store a decoded stream in a decoded picture buffer, wherein the decoded stream comprises a luminance component and a chrominance component a decoded stream. The range modification circuit receives the decoded stream, and modifies, if required, a luminance range of the luminance component and a chrominance range of the chrominance component. The range modification circuit further outputs a video stream. The video stream comprises the modified luminance component when the luminance modification signal is true, and the video stream comprises the luminance component when the luminance modification is false. Similarly, the video stream comprises the modified chrominance component when the chrominance modification signal is true, and the video stream comprises the chrominance component when the chrominance modification signal is false.

  • Patent number: 8375113
    Abstract: Technology is disclosed for controlling access to data store information among multiple entities. A corresponding wrapper is created for information that may be subject to simultaneous access attempts. The wrapper includes an attribute that identifies the accessibility of the information—indicating whether the information is locked from further access, shareable among multiple entities, or not restricted at all. Before accessing information in the data store, an entity looks at the wrapper associated with the information to determine the type of access allowed, if any. An Identity, Access, or integrated Identity/Access System may maintain the wrappers as objects in the data store, with each wrapper object controlling another object containing information. Wrappers can be utilized when multiple provisioning applications are employed to provision resources. Each user and their corresponding resources are represented as objects with corresponding wrappers.

  • Patent number: 8372719
    Abstract: A method of removing a hard mask during fabrication of semiconductor devices is provided. A protective layer, such as a bottom anti-reflective coating (BARC) layer or other dielectric layer, is formed over structures formed on a substrate, wherein spacers are formed alongside the structures. In an embodiment, the structures are gate electrodes having a hard mask formed thereon and the spacers are spacers formed alongside the gate electrodes. A photoresist layer is formed over the protective layer, and the photoresist layer may be patterned to remove a portion of the photoresist layer over portions of the protective layer. Thereafter, an etch-back process is performed, such that the protective layer adjacent to the spacers remains to substantially protect the spacers. The hard mask is then removed while the protective layer protects the spacers.
