A method for receiving a broadcast signal includes receiving the broadcast signal; frequency deinterleaving data in the broadcast signal based on an address generator the address generator including a sequence generator generating a sequence, a symbol offset generator generating a symbol offset, after applying the symbol offset to the sequence, the sequence to which the symbol offset is applied is checked whether an address of the sequence is within a range for the frequency deinterleaving, the address within the range is used for the frequency deinterleaving; decoding the frequency deinterleaved data of a signal frame in the broadcast signal, the decoded signal frame including one or more components included in a content and content information describing the content, the content information including component information including role information for at least one of an audio component, a video component, a closed caption component or an application component of the one or more components; and displaying information related to the content based on the role information of the one or more components of the content in the decoded broadcast signal.
