    Abstract: A method of operating a media player is provided. In one embodiment the method includes receiving a plurality of initially configured video settings for viewing a video segment on the media player for a desired playback duration. The method further includes determining power required to play the video segment based on the initial video settings and playing the video segment if the required power matches or is less than total power available to the media player. In another embodiment, the method may further include, if the required power exceeds the total power available to the media player, adjusting one or more of the initial video settings, either automatically or by user inputs, to reduce the power required to play the requested video segment for the desired playback duration.

    Abstract: A digital rights management (“DRM”) system is described that seeks to restrict the use and execution of certain computer program code to those hardware systems or platforms authorized by the provider of the protected software. To this end, certain computer programs (or portions thereof) are provided to authorized users in an encrypted format. When a “protected” program is to be executed, it is retrieved and stored in its encrypted format in operating system memory where it is accessible to operating system level routines (e.g., a file read operation). It is also decrypted and placed in another memory such that only the process executing the protected program has ready access to it.

    Abstract translation: 描述了一种数字版权管理（“DRM”）系统，其旨在将某些计算机程序代码的使用和执行限制于由受保护软件提供商授权的那些硬件系统或平台。 为此，某些计算机程序（或其部分）以加密格式提供给授权用户。 当要执行“受保护的”程序时，它被检索并以其加密格式存储在操作系统存储器中，在操作系统存储器中可操作系统级例程（例如，文件读取操作）。 它也被解密并放置在另一个存储器中，使得只有执行受保护程序的进程才能对其进行访问。

    Abstract: Exemplary embodiments of methods and apparatuses to manage a power of a system that leverage intermediate power margins are described. One or more subsystems of the system are operated at one or more performance points. A power consumed by the one or more subsystems at each of the one or more performance points is measured. An operational power of the one or more subsystems at the one or more performance points is determined. The one or more subsystems are operated at well-known conditions at the one or more performance points. The operational power may be adjusted based on data associated with the one or more subsystems. The operational power is provided to a power lookup table. The power is distributed among the one or more subsystems based on the operational power.

    Abstract: Methods and apparatuses for dynamically budgeting power usage in a data processing system. In one aspect, a data processing system, includes: one or more first components capable of being dynamically throttled to a plurality of different performance level settings; one or more second components; and one or more power usage sensors.

    Abstract: A method and system is disclosed for passing data processed by a DMA controller through a transmission filter. The method includes the DMA controller accessing data for transfer between an origination location in the system and a destination location in the system. The accessed data is passed through the DMA controller before being sent to the destination location. While the data is being passed through the DMA controller, it is passed through a transmission filter for processing. This processing may include the addition or removal of transmission protocol headers and footers, and determination of the destination of the data. This processing may also include hash-based packet classification and checksum generation and checking. Upon completion of the processing, the data is sent directly to a prescribed destination location, typically either a memory circuit or an I/O device.
