摘要:
The disclosed embodiments provide a system that facilitates interaction between an electronic device and a remote display. The system includes a first application and an encoding apparatus on the electronic device, and a second application and a decoding apparatus on the remote display. The first application obtains graphical output for a display of the electronic device and a set of filtering parameters associated with the graphical output. Next, the encoding apparatus encodes the graphical output, and the first application transmits the graphical output and the filtering parameters to the remote display. Upon receiving the graphical output and the filtering parameters at the remote display, the decoding apparatus decodes the graphical output. The second application then uses the graphical output to drive the remote display and the filtering parameters to obscure a subset of the graphical output on the remote display.

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.
摘要:
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.

A hierarchical movie is provided. A hierarchical movie is a movie that contains one or more embedded movies. Embedded movies may themselves contain embedded movies. Each movie contains zero or more media sequences. Within a hierarchical movie, media sequences that should be edited together may be grouped together using embedded movies. The media sequences of a hierarchical movie may be sequenced during playback based on a different time coordinate system than the time coordinate system that governs any embedded movies. This allows a movie to contain both time-based and time-independent media sequences. Also, the relative timing of events in the movie may vary from performance to performance. The hierarchical movie structure allows movies to be used as user interface controls, and even as field-sensitive databases.

An apparatus for synchronizing data retrieval is described. The apparatus comprises a storage media storing data, a storage control device coupled to the storage media for retrieving the data from the storage media, memory coupled to the storage control device for storing the data; and a scheduling unit coupled to the memory for scheduling retrieval of the data from the storage media before a specified time. A storage media for storing computer instructions is also described. The storage media comprises a first plurality of processor executable instructions for instructing a computer system to schedule retrieval of data from a storage device before a specified time, a second plurality of processor executable instructions for instructing the computer system to retrieve the data from the storage device before the specified time has elapsed, a third plurality of processor executable instructions for instructing the computer system to store the data from the storage device into memory, and a fourth plurality of processor executable instructions for instructing the computer system to process the data from the memory. A method for synchronizing data retrieval in a data processing system is also described. The method comprises determining a specified time for retrieving the data from a storage media, scheduling retrieval of the data from the storage media before the specified time, retrieving the data from the storage media before the specified time has elapsed, and processing the data from the storage media.
摘要:
A method is provided through which information about media files embedded in web pages is obtained from a server and analyzed to determine if the media files are playable on a device. This information may be external to the media file or may be a portion of the media file itself. The determination of whether a media file is playable by a device is made based on information obtained from the server without downloading the entirety of the media file.
摘要:
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.
