  • Data-driven media management within an electronic device
    Publication number: 20090005891
    Abstract: A method and apparatus for intelligently routing and managing audio signals within an electronic device is disclosed. The routing is responsive to a set of logical and physical policies which are stored in data tables which can be updated as needed.

  • CAPTURING MEDIA IN SYNCHRONIZED FASHION
    Publication number: 20080304573
    Abstract: Techniques for synchronizing audio and video content for presentation to a user at a same rate are provided. Streams of content from two or more sources of media, each media source having an associated clock, are synchronized by a synchronizing component and processor with respect to a master clock. As well, techniques are provided for ensuring that output devices are synchronized at preview startup. That is, such techniques ensure that the output devices start playing the media at the same time as well as at the same rate.

  • Time synchronization of multiple time-based data streams with independent clocks
    Publication number: 20080168294
    Abstract: Techniques are described for synchronizing multiple time-based data streams with independent clocks wherein relationships between clock rates of timing devices associated with the time-based data streams are determined, and based on these relationships, times in at least one of the time-based data streams may be translated to times in any of the other time-based data streams despite the data streams having independent clocks.

  • Time synchronization of media playback in multiple processes
    Publication number: 20080168470
    Abstract: Systems, methods, devices enable the efficient synchronization of timing information from first time-based process to a second time-based process using periodic or event-driven synchronization messages.
