摘要:
A personal computer based, multimedia, data processing system includes a software solution to the problem of synchronizing two or more data streams which output data to two or more multimedia output devices. One stream is a master and each other stream is a slave. The master stream generates sync pulses that can be handled in two different synchronization methods, master-slave independent synchronization or master-driven slave synchronization. Sync pulses are generated with a predetermined granularity, and synchronization is achieved when a slave stream is out of tolerance. Adaptive resynchronization may be used to speed up or slow down a slave stream.

A multimedia data processing system includes a memory for storing multimedia application programs and a multitasking operating system. Extensions to the operating system control data streaming from source devices to target devices to provide real-time, continuous streaming. The extensions provide central buffer management with a user buffer option, bi-level priority support for data stream handlers, support for interleaved streams, and data stream event detection and notification.

A data stream is created for moving data from a source to a target in accordance with a stream protocol defined by controlling stream protocol control blocks (SPCBs) created from a predefined source SPCB and a predefined target SPCB. The controlling SPCBs include information establishing a plurality of data buffers that are used to efficiently stream or transfer data on a real-time basis. The controlling SPCBs are formed by a process of negotiation in which differences between the source and target SPCBs are reconciled in accordance with rules of negotiation. Once the data stream is created, it is then started by the application program and data is streamed until an end of stream is reached.

The invention provides a system and method of enhancing efficiency in a data processing system having a processor, a memory, and a multitasking operating system for managing the processor and the memory. A normal and an expedited scheduling path are provided for scheduling tasks on the processor. The tasks are each assigned a priority for execution on the processor. A queue is provided for the placement of tasks ready for execution. Upon entry into the ready-to-run queue, the execution priority of the new task is compared to the execution priority of the executing task. Responsive to the new task holding a higher execution priority or to absence of an executing task, the expedited scheduling path is invoked. Otherwise the normal scheduling path is invoked.

Producing, by a digital media production hub from users' digital expressions of preferences, information describing a user community's preference for replacing the modifiable part of the digital media product with a replacement part; receiving, in the digital media production hub from a media product owner, the digital media product and a digital grant of rights to modify and distribute the digital media product; receiving, by the digital media production hub from a media parts provider, at least one replacement part, a digital grant of rights to use the replacement part to modify the digital media product, and a digital grant of rights to distribute the replacement part with the digital media product; and replacing, by the digital media production hub in accordance with the information describing the user community preference and the digital grants of rights, the modifiable part with the replacement part.
摘要:
A method of scheduling a request for a plurality of Web services can include providing service activation rules. Each service activation rule can specify a trigger condition and a state condition for causing a watcher to invoke a particular Web service. The method also can include receiving an event indicating a change in a common memory, wherein each event specifies trigger information, comparing the trigger conditions of the service activation rules with the trigger information of the event, adding the service activation rules that match the event to a trigger list, and comparing the state conditions of service activation rules in the trigger list with a state of the common memory. The service activation rules of the trigger list that match the state of the common memory can be selected thereby causing the invocation of at least one watcher and corresponding Web service.

A method, system and apparatus for service management. In accordance with the present invention, a service management method can include the steps of receiving a telephone call from a service subscriber over a PSTN and identifying the service subscriber through identifying information received externally to the received telephone call. Importantly, a service term for a subscription associated with the service subscriber can be modified only if payment can be resolved on behalf of the service subscriber.
摘要:
The present invention can include a method of call processing using a distributed voice browser including allocating a plurality of service processors configured to interpret parsed voice markup language data and allocating a plurality of voice markup language parsers configured to retrieve and parse voice markup language data representing a telephony service. The plurality of service processors and the plurality of markup language parsers can be registered with one or more session managers. Accordingly, components of received telephony service requests can be distributed to the voice markup language parsers and the parsed voice markup language data can be distributed to the service processors.
摘要:
A voice browser configured to process voice markup language documents can include a voice processing application and an integrated communications interface for interacting with a voice processing system. The voice browser can be configured to load the voice processing application independently of a received telephone call. The integrated communications interface can include at least one of an integrated transaction capabilities application part component for receiving a transaction capabilities application part query and an integrated ISUP component for receiving a telephony control signal.
