Abstract

Tools are provided for distributing access-restricted content in an internet protocol television ('IPTV') environment based on portable entitlement keys. Such tools can include a decoder, an encoder, and a network entitlement handler. The decoder may be configured to receive a key associated with entitlement information, and transmit the entitlement information over a network. The encoder may be configured to receive content from content providers, and to encode the content to create IP-compatible content, with access restrictions based on entitlement. The network entitlement handler may be configured to receive a request for requested content from the decoder; receive the access-restricted content (including the requested content) from the encoder; and transmit the requested content over the network to the decoder using IP, when the decoder is entitled to receive the requested content.
