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: According to one embodiment, a media system communicates with an aggregate device that includes multiple media output devices. When providing media data for presentation, the system adjusts for device clock drift by resampling the media data provided to a media output device based at least in part on a device clock rate difference between a device clock of one of the media output devices and a device clock of another of the media output devices.
Abstract translation: 根据一个实施例，媒体系统与包括多个媒体输出设备的聚合设备进行通信。 当提供用于呈现的媒体数据时，系统通过至少部分地基于媒体输出设备之一的设备时钟与设备之间的设备时钟速率差重新采样提供给媒体输出设备的媒体数据来调整设备时钟漂移 另一个媒体输出设备的时钟。

Abstract: Systems and methods for switching between encoded media streams are disclosed. A system may be configured to receive at least two media streams of differing qualities that are associated with an identical media asset. The system can seamlessly switch between a first media stream and a second media stream using an algorithm that can determine which frames of a second stream must be discarded to sync the second stream with the first media stream. The two media streams can then be cross faded to switch from the first media stream to the second media stream.
