<p>A set-top box of a first subscriber facilitates the creation of a first message to alert a second subscriber to a live broadcast going on. The first message is sent to a server on the Internet. The server creates a second message based on the first message and sends it to the set-top box of the second subscriber. The set-top box of the second subscriber alerts the latter to the second message. Upon opening the second message, the second subscriber can interact with interactive features contained in the second message so as to facilitate the tuning in on the live broadcast indicated by the first subscriber.</p> |
