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.

Claims

1. A device, comprising:

one or more processors to;

receive first mapping information associated with a set of remote segment identifiers that identify a set of remote locations, external from a local area network, from which a first set of segments of media content are accessible;

the second set of segments corresponding to the first set of segments;

store redirect information that associates the first mapping information and the second mapping information;

receive a request, associated with the media content, that includes a remote segment identifier of the set of remote segment identifiers;

determine a local segment identifier, of the set of local segment identifiers, based on the remote segment identifier and the redirect information,

the local segment identifier mapping to the remote segment identifier; and

request a segment of the media content using the local segment identifier.

2. The device of claim 1, where the set of remote segment identifiers are used to identify a first device external from the local area network;

and

where the set of local segment identifiers are used to identify a second device internal to the local area network.

3. The device of claim 1, where the first mapping information includes a first set of uniform resource identifiers corresponding to the set of remote segment identifiers;

and

where the second mapping information includes a second set of uniform resource identifiers corresponding to the set of local segment identifiers,

the second set of uniform resource identifiers being different from the first set of uniform resource identifiers.

4. The device of claim 1, where the first mapping information includes a first set of uniform resource identifier portions corresponding to the set of remote segment identifiers;

and

where the second mapping information includes a second set of uniform resource identifier portions corresponding to the set of local segment identifiers,

the second set of uniform resource identifier portions being different from the first set of uniform resource identifier portions.

5. The device of claim 1, where the first mapping information includes a remote key identifier associated with the set of remote segment identifiers,

the remote key identifier identifying a remote location where a remote key is stored;

and

where the second mapping information includes a local key identifier associated with the set of local segment identifiers,

the local key identifier identifying a local location where a local key is stored.

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

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

request the remote key using the remote key identifier.

7. The device of claim 1, where the one or more processors are to:

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

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;

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 the media content are accessible,

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

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

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

and

where the second set of segment identifiers are used to identify one or more devices internal to the local area network.

10. The non-transitory computer-readable medium of claim 8, where the one or more instructions, when executed by the one or more processors, further cause the one or more processors to:

determine a key identifier, associated with the second segment identifier, based on the redirect information,

the key identifier identifying a remote location from which a security key, associated with the segment of the media content, is accessible; and

obtain the security key using the key identifier; and

where the one or more instructions, that cause the one or more processors to request the segment of the media content, cause the one or more processors to;

request the segment of the media content using the security key.

11. The non-transitory computer-readable medium of claim 8, where the one or more instructions, when executed by the one or more processors, cause the one or more processors to:

receive first mapping information associated with the first set of segment identifiers;

receive second mapping information associated with the second set of segment identifiers; and

store the redirect information based on the first mapping information and the second mapping information,

the redirect information being used to map the first set of segment identifiers and the second set of segment identifiers based on the first mapping information and the second mapping information.

12. The non-transitory computer-readable medium of claim 11, where the one or more instructions, that cause the one or more processors to receive the first mapping information, cause the one or more processors to:

receive the first mapping information from the media client.

13. The non-transitory computer-readable medium of claim 11, where the one or more instructions, that cause the one or more processors to receive the second mapping information, cause the one or more processors to:

receive the second mapping information from a device other than the media client.

14. A method, comprising:

receiving, by a device, first mapping information associated with a set of remote segment identifiers that identify a set of remote locations, external from a local area network to which the device is connected, from which a first set of segments of media content are accessible;

receiving, by the device, second mapping information associated with a set of local 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,
