Patent ID: 8493912

Claim:
A method of transmitting a signal, the method comprising: converting a service stream to a physical layer pipe (PLP), the service stream for delivering a service; building a time-frequency slicing (TFS) signal frame, the TFS signal frame including the PLP and layer-1 information; modulating the TFS signal frame according to an orthogonal frequency division multiplexing (OFDM) scheme in order to generate a modulated signal; and transmitting the modulated signal via at least one radio frequency (RF) band signal, wherein the layer-1 information includes an index of a current RF channel within the TFS signal frame and an identifier of an RF channel that includes the PLP in a first TFS signal frame of a super frame of TFS structure, wherein the identifier of the RF channel is included in a configurable part of the layer-1 information, wherein the configurable part is changed in a unit of the super frame, wherein the TFS signal frame includes signal frame identification information that comprises an effective portion, a cyclic prefix obtained by frequency-shifting a first portion of the effective portion, and a cyclic suffix obtained by frequency-shifting a second portion of the effective portion, and wherein the first portion is a foremost part of the effective portion and the second portion is a rearmost part of the effective portion.
