摘要： A data processing system is provided for executing multimedia applications which interface with multimedia end devices that consume or produce at least one of (a) real-time and (b) asynchronous streamed data. The data processing system includes a central processing unit for data processing operations including execution of the multimedia application, a digital signal processor for processing data including the streamed data, and a plurality of modular components which cooperate to provide a substantially open architecture. The plurality of modular components include a plurality of modular multimedia software tasks which are executable by the digital signal processor and which may be called by the multimedia application for execution in the digital signal processor, as well as a plurality of data communication modules for linking selected ones of the plurality of modular multimedia software tasks with selected others of the plurality of modular multimedia software tasks, and for linking selected multimedia end devices with selected ones of the plurality of modular multimedia software tasks. Each of the plurality of data communication modules allows continuous, real-time and unidirectional communication of streamed data. The enhanced connectivity of the modular approach for the multimedia data processing system allows additional modular multimedia software tasks to be added to the plurality of modular multimedia software tasks and selectively linked to selected ones of the plurality of modular multimedia software tasks and selected ones of the multimedia end devices.

摘要： Disclosed are apparatus and methods for synchronized presentation of analog and digital data by applying a common synchronization scheme to both types of data. Digital data is "streamed" by transferring the data in blocks from a source to a series of memory buffers, where it accumulates for subsequent transfer to an output device driver. The control module responsible for data streaming periodically reports a temporal location within the presentation represented by the data. A supervisory module designates one of the control modules a "master", and periodically compares the values reported by the various other control modules against that reported by the master. If a comparison exceeds a threshold tolerance value associated with each control module, a sync pulse is delivered to that control module, causing it to correct the synchronization mismatch. This approach is applied to analog sources through the use of control modules that behave in a manner consistent with the digital control modules, but which are capable of directing the operation of analog devices and re-establishing their synchronization with other data sources despite limited modes of device control. Specifically, the control modules that handle analog information also periodically report a presentation location based solely on temporal information, react to sync pulses by altering the playback rate of the analog devices they control within user-tolerable limits, and can act as master control modules.
摘要翻译：公开了通过对两种类型的数据应用公共同步方案来同步呈现模拟和数字数据的装置和方法。通过将块中的数据从源传送到一系列存储器缓冲器，数字数据被“流式传输”，其中它累积用于随后传送到输出设备驱动器。负责数据流的控制模块周期性地报告由数据表示的呈现内的时间位置。监控模块将控制模块中的一个指定为“主站”，并且周期性地将由各种其他控制模块报告的值与主站报告的值进行比较。如果比较超过与每个控制模块相关联的阈值容限值，则将同步脉冲传送到该控制模块，从而使其纠正同步失配。这种方法通过使用以与数字控制模块一致的方式运行的控制模块应用于模拟源，但是哪些能够指导模拟设备的操作并且重新建立与其他数据源的同步，尽管有限的模式设备控制。具体地说，处理模拟信息的控制模块也仅基于时间信息周期性地报告呈现位置，通过改变在用户可容忍的范围内控制的模拟设备的重放速率来对同步脉冲作出反应，并且可以作为主控模块。

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.

摘要： 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.
