Abstract

Subscribers to a television-delivery service can send and receive messages within a television-viewing environment. A subscriber can create a message, attach content from the television environment, and send the message to a friend, all without leaving the television environment. A television producer controls its rights to the content by allowing subscribers to select and send some content while preventing other content from being incorporated in a message. Rights can be checked at the sender site, at the recipient site, and in between by a message-transport service. In some situations, the recipient may not have sufficient rights to view the entire message. Specifically, the recipient's subscription level may not allow access to some of the message content that was pulled from the sender's television-delivery service. In this case, the recipient may take corrective action or may view the message with the restricted content replaced with alternative content.
