METHOD AND APPARATUS FOR PROVIDING CONTROL CHANNEL COMMUNICATIONS FOR AN INFORMATION DISTRIBUTION SYSTEM |
摘要 |
In an information distribution system (100), a control channel modem (114) provides independent communications channels for bi-directional message traffic between a service provider (102) and a set-to p terminal (118) located within a subscriber's home. The modem (114) transmits messages, control information and status information between the service provider (102) and the subscriber's set-top terminal (118) using an independent channel (downstream path) that is different from the channel (upstream path) used for sending requested information such as movies from the service provider (102) to the subscriber 's home (108).
