Protected information stream allocation using a virtualized platform

摘要

A protected stream manager includes one or more subsystems to receive a content stream in a virtual environment, obfuscate the content stream, and prioritize use of a processor to process the content stream.

主权项

1. A protected content securing system, comprising:
at least one processor; a memory; at least one hardware device that is coupled to the at least one processor and the memory, wherein the at least one hardware device is coupled to at least one virtual machine device including a plurality of virtual machines; a hypervisor located on the at least one hardware device, wherein the hypervisor includes a protected stream manager that is configured to:
receive multiple protected video content streams including a first protected television video content stream from a first virtual machine and a second protected stored video content stream from a second virtual machine;allocate a first portion of the memory for the first protected television video content stream and sequester a first data path for the first protected television video content stream to the first portion of the memory that prevents unauthorized systems from accessing the first protected television content stream on the first data path;allocate a second portion of the memory for the second protected stored video content stream and sequester a second data path for the second protected stored video content stream to the second portion of the memory that prevents unauthorized systems from accessing the second protected stored video content stream on the second data path;allocate a plurality of resources of the at least one processor for each of the first protected television video content stream and the second protected stored video content stream; andmanage the use of the plurality of resources of the at least one processor between the first virtual machine and the second virtual machine, allowing the first virtual machine to render the first protected television video content stream and the second virtual machine to render the second protected stored video content stream to play the multiple protected video content streams.
