a preamble symbol inserter configured to insert at least one preamble symbol in each of the plurality of frames, and insert, in a preamble symbol of a frame, location information about at least one frame, among the plurality of frames, which includes a same kind of data as a kind of data included in the frame; and
a transmitter configured to transmit the plurality of frames in each of which the preamble symbol is inserted,
wherein the location information includes at least one of number information and length information about at least one frame which exists between the frame and another frame separated from the frame by the shortest distance among a plurality of subsequent frames, subsequent to the frame, in which the same kind of data is included, and
wherein the same kind of data comprises a same PLP (Physical Layer Pipe).
2. The transmitting apparatus as claimed in claim 1 , wherein the one or more kinds of the data comprises at least one of a first kind of data for a fixed terminal and a second kind of data for a mobile terminal.
3. The transmitting apparatus as claimed in claim 2 , wherein the preamble symbol includes an indicator field which indicates whether the data included in the frame is for a fixed terminal or a mobile terminal.
4. A receiving apparatus, comprising:
a receiver configured to receive a plurality of frames in each of which at least one preamble symbol is inserted and one or more kinds of data are included;
a signaling processor configured to detect, from a preamble symbol of a frame, location information about at least one frame, among the plurality of frames, which includes a same kind of data as a kind of data included in the frame; and
a signal processor configured to selectively process the frame and the at least one frame which includes the same kind of data, based on the location information,
wherein the location information includes at least one of number information and length information about at least one frame which exists between the frame and another frame separated from the frame by the shortest distance among a plurality of subsequent frames, subsequent to the frame, in which the same kind of data is included, and
wherein the same kind of data comprises a same PLP (Physical Layer Pipe).
5. The receiving apparatus as claimed in claim 4 , wherein the signal processor calculates a time corresponding to the shortest distance based on the at least one of the number information and the length information.
6. The receiving apparatus as claimed in claim 5 , wherein the signal processor maintains a stand-by state during the calculated time, and operates in a normal state when the other frame separated from the frame by the shortest distance is processed after the calculated time elapses.
7. The receiving apparatus as claimed in claim 4 , wherein the one or more kinds of the data comprises at least one of a first kind of data for a fixed terminal and a second kind of data for a mobile terminal.
8. The receiving apparatus as claimed in claim 7 , wherein a preamble symbol inserted in the other frame includes an indicator filter which indicates whether data included in the other frame is for a fixed terminal or a mobile terminal.
9. A controlling method of a transmitting apparatus, comprising:
generating a plurality of frames which include one or more kinds of data;
inserting at least one preamble symbol in each of the plurality of frames;
inserting, in a preamble symbol of a frame, location information about at least one frame, among the plurality of frames, which includes a same kind of data as a kind of data included in the frame; and
transmitting the plurality of frames in each of which the preamble symbol is inserted,
wherein the location information includes at least one of number information and length information about at least one frame which exists between the frame and another frame separated from the frame by the shortest distance among a plurality of subsequent frames, subsequent to the frame, in which the same kind of data is included, and
wherein the same kind of data comprises a same PLP (Physical Layer Pipe).
10. The method as claimed in claim 9 , wherein the one or more kinds of data comprises at least one of a first kind of data for a fixed terminal and a second kind of data for a mobile terminal.
11. The method as claimed in claim 10 , wherein the preamble symbol includes an indicator field which indicates whether the data included in the frame is for a fixed terminal or a mobile terminal.
12. A controlling method of a receiving apparatus, comprising:
receiving a plurality of frames in each of which a preamble symbol is inserted and one or more kinds of data are included;
detecting, from a preamble symbol of a frame, location information about at least one frame, among the plurality of frames, which includes a same kind of data as a kind of data included in the frame; and
selectively processing the frame and the at least one frame which includes the same kind of data, based on the location information,
wherein the location information includes at least one of number information and length information about at least one frame which exists between the frame and another frame separated from the frame by the shortest distance among a plurality of subsequent frames, subsequent to the frame, in which the same kind of data is included, and
wherein the same kind of data comprises a same PLP (Physical Layer Pipe).
13. The method as claimed in claim 12 , wherein the selectively processing comprises calculating a time corresponding to the shortest distance based on the at least one of the number information and the length information.
14. The method as claimed in claim 13 , wherein the selectively processing comprises maintaining the receiving apparatus in a stand-by state during the calculated time, and operating the receiving apparatus in a normal state when the other frame separated from the frame by the shortest distance is processed after the calculated time elapses.
15. The method as claimed in claim 12 , wherein the one or more kinds of the data comprises at least one of a first kind of data for a fixed terminal and a second kind of data for a mobile terminal.
16. The method as claimed in claim 15 , wherein a preamble symbol inserted in the other frame includes an indicator field which indicates whether data included in the other frame is for a fixed terminal or a mobile terminal.
