Method and apparatus for processing contents using TV channel in home network

A method and an apparatus for processing contents are provided to allow users to easily reproduce desired files through switching of channels by allocating network contents to empty channels to which broadcast signals are not allocated. The first and the second channel information are respectively stored(420). The first channel information relates to empty channels to which broadcast signals are allocated, and the second channel information relates to channels to which broadcast signals are not allocated. A request for a content list is transmitted to server devices connected to a home network(430). The content list is received from the server devices(440). The received content list is mapped to the empty channels(450). When one of empty channels to which the content list is mapped is selected, contents corresponding to the selected channel are reproduced(488).
