METHODS AND SYSTEMS FOR PROVIDING INFORMATION TO SET-TOP BOXES HAVING SET-TOP BOX IDENTIFIERS USING FREQUENCY SHIFT KEYING MODULATION

摘要

A set-top box is provided wherein an Identifier (ID) associated with the set-top box can be used to request information from a personal computer which provides the requested information to the set-top box. In particular, in a system that includes multiple set-top boxes, the ID can be used to determine which set-top box made a request and to determine which set-top box is the intended recipient of the requested information accessed by the system. The information can be provided over a cable which is used to connect a television signal. In particular, the information can be transferred using frequency shift keying modulation.
