Secure license enforcement for expandable peripherals on IoT (sleepi) devices

A system for media play management, the system comprising:

• a trusted execution environment;
• one or more processors;
• and
• memory including instructions which, when executed by the one or more processors, cause the one or more processors to:
• detect a trigger while a media file is playing using a first play characteristic, the trigger indicating a change from the first play characteristic to a second play characteristic, the first play characteristic associated with a first license and a first streaming media file format;
• cause a first indication of a first portion of the media file having been played based on the first license to be transmitted;
• in response to detecting the trigger, instruct the trusted execution environment to:
• transmit an indication of supported display topologies to a content provider of the media file, and
• request the media file in a second streaming media file format from the content provider, the second streaming media file format compatible with at least one of the supported display topologies;
• upon receiving the media file in the second streaming media file format, play, in the trusted execution environment, a second portion of the media file on the local device based on a second license for the second streaming media file format;
• and
• cause a second indication of the second portion of the media file having been played based on the second license to be transmitted.

A computer readable storage device or storage disc comprising computer readable code which, when executed, causes one or more computer processors to at least:

• in response to a request to stream a media file under a second license from a remote device currently streaming the media file under a first license, provision the second license for the media file based on the request, the first and second licenses associated with first and second file formats, respectively;
• provide the media file to the remote device in the second file format associated with the second license;
• obtain from a trusted execution environment, one or more indications of a first portion of the media file streamed under the first license and a second portion of the media file streamed under the second license;
• and
• generate a bill that includes charges for the first portion of the media file streamed under the first license and for the second portion of the media file streamed under the second license.

A system for media play management, the system comprising:

• one or more processors;
• and
• memory including instructions which, when executed, cause at least some of the one or more processors to:
• in response to a request to stream a media file under a second license, received from a remote device currently streaming the media file under a first license, provision the second license for the media file, the first and second licenses associated with first and second file formats, respectively;
• stream the media file to the remote device in the second file format associated with the second license;
• obtain from a trusted execution environment, one or more indications of a first portion of the media file streamed under the first license and a second portion of the media file streamed under the second license;
• and
• generate a bill that includes first charges for the first portion of the media file streamed under the first license and second charges for the second portion of the media file streamed under the second license.

A method for media play management, comprising:

• in response to a request to stream a media file under a second license from a remote device currently streaming the media file in a first format under a first license, provisioning, by executing an instruction with at least one processor, the second license for the media file based on the request;
• obtaining from a trusted execution environment, by executing an instruction with at least one processor, one or more indications of a first portion of the media file streamed under the first license and a second portion of the media file streamed under the second license;
• and
• generating, by executing an instruction with at least one processor, a bill having a first charge for the streaming of the first portion of the media file under the first license and having a second charge for the streaming of the second portion of the media file under the second license.
