Protected media pipeline

摘要

A system for processing a media content comprising an application space, a media control mechanism operating in the application space, the media control mechanism controlling the operation of the system, a user interface adapted to provide input to the media control mechanism, a protected space distinct from the application space, and a protected media pipeline operating in the protected space, the protected media pipeline coupled to the media control mechanism, the protected media pipeline adapted to access the media content, process the media content, and output the media content.

主权项

1. A system comprising a computing device and at least one software module that are together configured for processing media content, the system comprising:
a media source having an input and an output, the media source configured for operating in a protected space provided within the computing device, the input of the media source coupled to a first secure connection over which the media content is received via the media source into the protected space; a plurality of transform mechanisms having an input and an output and configured for operating in the protected space provided within the computing device, the input of the plurality of transform mechanisms coupled to the output of the media source, where the plurality of transform mechanisms are configured for processing the media content; a media sink having an input and an output, the media sink configured for operating in the protected space provided within the computing device, the input of the media sink coupled to the output of the plurality of transform mechanisms, the output of the media sink coupled to a second secure connection over which the processed media content is transferred via the media source out of the protected space, where the media source, the plurality of transform mechanisms, and the media sink are separate from each other and together form a protected media pipeline that includes an output and an input and that is configured for processing the media content within the protected space of the computing device.
