摘要： A method to dynamically reconfigure multimedia streaming processing modules using interfaces that allow applications and modules to seamlessly change the configuration of streaming modules. Reconfigurations are initiated by a processing module in a stream or by an application by sending a notification packet through the processing modules in the portion of the stream being changed that informs that modules that a change is being made and the modules to complete processing of its data. Modules affected by the change are stopped once the notification packet is received by all processing modules in the stream being changed and modules are then added, removed, or replaced and the portion of the stream being changed resumes processing the data stream. The modules at the beginning of the portion being changed can resume operation as soon as they are reconnected to other modules.

摘要翻译： 一种使用允许应用程序和模块无缝更改流模块配置的接口动态重新配置多媒体流处理模块的方法。 重新配置由流中的处理模块或应用程序通过在被改变的流的部分中的处理模块发送通知分组来发起，该部分通知模块正在进行改变，并且模块完成其数据的处理 。 一旦通过改变的流中的所有处理模块接收到通知分组，然后添加，删除或替换模块，并且更改的流的部分恢复处理数据流，则会影响受更改影响的模块。 在更改部分开头的模块可以在重新连接到其他模块后立即恢复运行。

摘要： A flexible interface that enables an application to communicate directly with processing modules to easily control the processing of streaming data. The interface provides basic commands for applications to use to communicate with processing modules and provides the flexibility to adapt to changing standards. The interface enables an application to set the type of input and output data formats of a processing module and control when the processing module processes input data and generates output data. The processing modules enumerate its capabilities by category, by media type, or by both category and media type. Processing modules are registered by class ID, category, whether the application needs a key, the number and types of input data types, and the number and type of output data types to register.

摘要： A set of interfaces and data structures (i.e., a demultiplexer API) for representing a demultiplexer of multimedia data is presented. The data structure utilizes a number of fields, each containing an element of a command. In one embodiment, at least seven commands are formed for proper operation of the demultiplexer, including Initialize, SetPresentationDescriptor, GetPresentationDescriptor, GetPendingPresentationDescriptor, ProcessInput, ProcessOutput, and Flush commands. The demultiplexer API allows the consumer to use muxed stream data such as DV in a uniform manner to generate elementary stream data such as audio and video (compressed or uncompressed) and allows demultiplexers to be used as an independent component.

摘要： A method facilitating media processing is presented comprising generating a prediction of a region of encoded media content, receiving an indication of a quantity of remaining residual samples, on a per-region basis, and adding a first of such samples to the prediction to generate a modified prediction, and subtracting a second of such samples from the modified prediction, if so indicated.

摘要： Resource management architectures implemented in computer systems to manage resources are described. In one embodiment, a general architecture includes a resource manager and multiple resource providers that support one or more resource consumers such as a system component or application. Each provider is associated with a resource and acts as the manager for the resource when interfacing with the resource manager. The resource manager arbitrates access to the resources provided by the resource providers on behalf of the consumers. A policy manager sets various policies that are used by the resource manager to allocate resources. One policy is a priority-based policy that distinguishes among which applications and/or users have priority over others to use the resources. A resource consumer creates an “activity” at the resource manager and builds one or more “configurations” that describe various sets of preferred resources required to perform the activity. Each resource consumer can specify one or more configurations for each activity. If multiple configurations are specified, the resource consumer can rank them according to preference. This allows the resource consumers to be dynamically changed from one configuration to another as operating conditions change.

摘要： The modification of timestamps of streams of data packets for seamless branching is disclosed. In one aspect of the invention, a computerized system has a plurality of multimedia play devices, and a multimedia read device. Each play device receives and plays data intended for that device. The multimedia read device reads a stream of packets of data, decodes the packets into data, and sends the data to a corresponding play device at appropriate times. The appropriate time is based on relative timestamps accounting for accumulated time gaps resulting from branches within the stream. The invention has applications including digital video disc (DVD) playback.
