CHANNEL SWITCHING METHOD AND CHANNEL RECEPTION METHOD TO INCREASE SPECTRUM USE EFFICIENCY, AND CHANNEL SWITCHING APPARATUS AND CHANNEL RECEPTION APPARATUS USING THE SAME

摘要

Provided is a channel switching method and channel reception method to enhance spectrum use efficiency and a channel switching apparatus and channel reception apparatus using the same. The channel switching method may include extracting, based on received information associated with a virtual channel currently viewed by a user, broadcasting data on a corresponding virtual channel in a physical channel, determining communication data to be added to an idle frequency band in the physical channel including the extracted broadcasting data, and transmitting a transmission data stream generated based on communication data and broadcasting data included in the physical channel, wherein the physical channel comprises broadcasting data on a plurality of virtual channels and uses a predetermined frequency band.
