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.
