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.

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.

Abstract: An operating system of a device receives, from an application executing on that device, data that identifies a category of hardware resources that the application needs to use in order to function. That category is mapped to a specified set of hardware resources of the device. The operating system also receives, from the application, data that identifies a mode. The mode corresponds to an intended use of a set of hardware resources and is mapped to a group of hardware resource settings that are consistent with the intended use. The operating system allocates, to the application, a particular set of hardware resources that are mapped to the category. The operating system configures one or more hardware resources in the particular set of hardware resources in conformity with a particular group of settings that are mapped to the mode.

Abstract: Systems, methods, devices that 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 are provided. In one aspect, the invention includes a media processing system having a first process for processing media based, at least in part, on first timing information derived from a first timing source and a second timing source. The system may also include a second process for processing the media based, at least in part, on second timing information derived from the first timing source. The first process may send one or more timing synchronization messages, generated based at least in part on the first timing source and the second timing source, to the second process to synchronize the second timing information with the first timing information.

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.

Abstract: Services for a personal electronic device are provided through which a form of background processing or multitasking is supported. The disclosed services permit user applications to take advantage of background processing without significant negative consequences to a user's experience of the foreground process or the personal electronic device's power resources. To effect the disclosed multitasking, one or more of a number of operational restrictions may be enforced. A consequence of such restrictions may be that a process will not be able to do in the background state, what it may be able to do if it were in the foreground state. By way of example, network-based applications may be suspended until a message is received for them. At that time, the suspended application may be moved into the background state where it is permitted to respond to the message. In a similar fashion, audio application may be permitted to execute in background until suspended by user action.

The disclosed services permit user applications to take advantage of background processing without significant negative consequences to a user's experience of the foreground process or the personal electronic device's power resources. To effect the disclosed multitasking, one or more operational restrictions may be enforced. A consequence of such restrictions, a process may not be able to do in the background state, what it may be able to do if it were in the foreground state. In one embodiment, while a background task may be permitted to complete a first task, it may not be permitted start a new task—being suspended after completion of the first task. Implementation of the disclosed services may be substantially transparent to the executing user applications.

The disclosed services permit user applications to take advantage of background processing without significant negative consequences to a user's experience of the foreground process or the personal electronic device's power resources. To effect the disclosed multitasking, one or more of a number of operational restrictions may be enforced. By way of example, an application that may normally be placed into the background state may instead be terminated if it controls a lock on a shared system resource.
