  • Patent number: 7742926
    Abstract: Compression of audio signal data is described herein. In various embodiments, the compression of each unit of the audio signal data includes the employment of a distribution substantially representative of a subblock of residual data of the unit of audio signal data, to reduce the amount of data having to be transmitted to transmit the unit of audio signal data to a recipient.

  • Patent number: 7721314
    Abstract: A system and method automates a scheduled retrieval, storage, and access of media data. Media data is retrieved from an external source and downloaded to an end user media device storage for subsequent playback at the end user media device. Media data is accessible from the end user media device storage based upon criteria including a selection of the end user, rules regulating the media data, and whether a playback time of the media data is sufficient to retrieve additional media data. The system performs regularly scheduled dynamic controls to determine whether additional media data is required for continuous and uninterrupted access of the media data.

  • Patent number: 7721111
    Abstract: In accordance with one embodiment of the present invention, secure content objects are transcoded from an input format to an output format based upon identified capabilities of a receiving device. In one embodiment, a plurality of trusted processing components are identified to collectively transcode the secure content object from the identified input format to the determined output format. In one embodiment, each of the trusted processing components are authenticated prior to operating on the secure content object.

  • Patent number: 7636860
    Abstract: A number of digital content rendering modules are equipped such that selective subsets of the modules may be employed to render digital content of different media, and of different format types. The modules are organized into a hierarchy, with a selected one occupying a root position of the hierarchy, to exclusively receive the digital contents to be rendered, and that each module is further responsible for verifying the integrity of its immediate downstream modules, to collectively protect the digital contents being rendered. Additionally, in accordance with another aspect, a tamper resistant module is employed to recover digital contents provided in a protected state, obfuscating the recovery. Further, the modules may be of different application domains.

  • Patent number: 7606312
    Abstract: Streamlined prediction approaches are provided to predict pixel values of a 4×4 subblock of a macroblock of video data being encoded, under a number of prediction modes. Additionally, prediction approaches are provided to predict pixel values of a non-4×4 M×N subblock of a macroblock of video data being encoded, under a number of prediction modes, including 8×8, 8×4 and 4×8 subblocks. The invention may be practiced in an encoder and/or a decoder of a video apparatus.
