Abstract

Aspects of the subject disclosure may include, for example, a local server coupled to a plurality of client devices. The local server may receive encrypted content from one or more content sources and provide the content to the client devices. The local server and client devices may be part of a multi-client environment such as a hotel or conference center. The local server does not decrypt and re-encrypt content, thereby allowing the use of low cost equipment. Other embodiments are disclosed.

Claims20

Dependent claims

A device, comprising:

a local server including a processor;
and
a memory that stores executable instructions that, when executed by the local server, facilitate performance of operations, the operations comprising:
receiving a first request for first encrypted media content associated with a first broadcast channel from each of a first plurality of client devices;
receiving the first encrypted media content from a first content source intended for the first plurality of client devices, wherein the first content source broadcasts the first encrypted media content to a group of network devices, wherein the first content source comprises a satellite system, wherein the group of network devices comprises the local server;
receiving a second request for a second encrypted media content associated with a second broadcast channel from each of a second plurality of client devices;
receiving the second encrypted media content from a second content source intended for the second plurality of client devices, wherein the second content source broadcasts the second encrypted media content to the group of network devices, wherein the second content source comprises a broadband content source, wherein the group of network devices comprises a local server;
caching the first encrypted media content in a media content storage device resulting in cached first encrypted media content;
caching the second encrypted media content in the media content storage device resulting in cached second encrypted media content;
receiving a third request for at least one first decryption key associated with the first encrypted media content from at least one of the first plurality of client devices;
receiving a fourth request for at least one second decryption key associated with the second encrypted media content from at least one of the second plurality of client devices;
providing the at least one first decryption key to the at least one of the first plurality of client devices;
providing the at least one second decryption key to the at least one of the second plurality of client devices;
accessing the cached first encrypted media content from the media content storage device;
accessing the cached second encrypted media content from the media content storage device;
multicasting the cached first encrypted media content to the first plurality of client devices;
and
multicasting the cached second encrypted media content to the second plurality of client devices.

A non-transitory, machine-readable medium, comprising executable instructions that, when executed by a local server including a processor, facilitate performance of operations, the operations comprising:

receiving, at a local server, a first request for first encrypted media content associated with a first broadcast channel from each of a first plurality of client devices;
receiving, at the local server, first encrypted media content from a first content source intended for the first plurality of client devices, wherein the first content source broadcasts the first encrypted media content to a group of network devices, wherein the first content source comprises a satellite system, wherein the group of network devices comprises the local server;
receiving, at the local server, a second request for second encrypted media content associated with a second broadcast channel from each of a second plurality of client devices;
receiving, at the local server, the second encrypted media content from a second content source intended for the second plurality of client devices, wherein the second content source broadcasts the second encrypted media content to the group of network devices, wherein the second content source comprises a broadband content source;
caching, by the local server, the first encrypted media content in a media content storage device resulting in cached first encrypted media content;
caching, by the local server, the second encrypted media content in the media content storage device resulting in cached second encrypted media content;
receiving, at the local server, a third request for at least one first decryption key associated with the first encrypted media content from at least one of the first plurality of client devices;
receiving, at the local server, a fourth request for at least one second decryption key associated with the second encrypted media content from at least one of the second plurality of client devices;
providing, by the local server, the at least one first decryption key to the at least one of the first plurality of client devices;
providing, by the local server, the at least one second decryption key to the at least one of the second plurality of client devices;
accessing, by the local server, the cached first encrypted media content from the media content storage device;
accessing, by the local server, the cached second encrypted from the media content storage device;
multicasting, by the local server, the cached first encrypted media content to the first plurality of client devices;
and
multicasting, by the local server, the cached second encrypted media content to the second plurality of client devices.

receiving, by the local server, a fourth request for at least one second decryption key associated with the second encrypted media content from at least one of the second plurality of client devices;
providing, by the local server, the at least one first decryption key to the at least one of the first plurality of client devices;
providing, by the local server, the at least one second decryption key to the at least one of the second plurality of client devices;
accessing, by the local server, the cached first encrypted media content from the media content storage device;
accessing, by the local server, the cached second encrypted media content from the media content storage device;
multicasting, by the local server, the cached first encrypted media content to the first plurality of client devices;
and
multicasting, by the local server, the second encrypted media content to the second plurality of client devices.
