Abstract

A device may receive a request, associated with media content, that includes a first segment identifier of a first set of segment identifiers that identify a set of remote locations, external from a local area network, from which a first set of segments of the media content are accessible. The device may determine, based on the first segment identifier and redirect information, a second segment identifier of a second set of segment identifiers that identify a set of local locations, internal to the local area network, from which a second set of segments of media content are accessible. The second set of segments may correspond to the first set of segments. The redirect information may indicate that the second segment identifier corresponds to the first segment identifier. The device may request a segment of the media content using the second segment identifier.

6. The device of claim 5, where the one or more processors are further to:

request the remote key using the remote key identifier.

7. The device of claim 1, where each remote segment identified, of the set of remote segment identifiers, identifies a remote location of the set of remote locations associated with a wide area network.

8. A non-transitory computer-readable medium storing instructions, the instructions comprising:

one or more instructions that, when executed by one or more processors, cause the one or more processors to;

receive a request, associated with media content, that includes a first segment identifier of a first set of segment identifiers that identify a set of remote locations, external from a local area network, from which a first set of segments of the media content are accessible,

the request including a remote key identifier associated with the first set of segment identifiers;

map the first segment identifier to a second segment identifier, of a second set of segment identifiers,

the second set of segment identifiers being associated with a local key identifier,

the first segment identifier, of the first set of segment identifiers, to map to the second segment identifier, of the second set of segment identifiers;

determine, based on mapping the first segment identifier to the second segment identifier and based on redirect information, the second segment identifier of the second set of segment identifiers that identify a set of local locations, internal to the local area network, from which a second set of segments of the media content are accessible,

the second set of segments corresponding to the first set of segments, and

the redirect information indicating that the second segment identifier corresponds to the first segment identifier;

determine the local key identifier based on the remote key identifier and the redirect information;

request a segment of the media content using the second segment identifier;

request a local key using the local key identifier,

the local key to encrypt of the segment of the media content and authenticate communication; and

provide the segment of the media content to a media client.

9. The non-transitory computer-readable medium of claim 8, where the first set of segment identifiers are used to identify one or more devices external from the local area network;
