Abstract

A method and apparatus for transmitting data comprising a plurality of data streams in a broadcasting system are provided. The method includes dividing a frame into a plurality of physical layer zones; allocating the plurality of data streams to at least one of the plurality of physical layer zones; allocating signaling information associated with the plurality of physical layers to at least one of the plurality of physical layer zones; and transmitting the frame to which the signaling information is allocated.

Claims

1. A method of transmitting data comprising a plurality of data streams in a broadcasting system, the method comprising:

dividing a frame into a plurality of physical layer zones;

allocating the plurality of data streams to at least one of the plurality of physical layer zones;

allocating signaling information associated with the plurality of physical layers to at least one of the plurality of physical layer zones; and

transmitting the frame to which the signaling information is allocated.

2. The method of claim 1, wherein the signaling information comprises at least one of locations of the physical layer zones, characteristics of the physical layer zones, and allocation information of the data streams with respect to the physical layer zones.

3. The method of claim 2, wherein the characteristic of the physical layer zone comprises at least one of the number of sub-carriers of respective Orthogonal Frequency Division Multiplexing (OFDM) symbols, a length of a guard period between the OFDM symbols, a ratio of pilot sub-carriers to payload sub-carriers, and a multiple antenna transmission scheme.

4. The method of claim 2, wherein at least one first physical layer zone characteristic among the characteristics of the physical layer zones is applied uniformly within symbols of the respective physical layer zone and is applied differently between different physical layer zones.

5. The method of claim 1, wherein the signaling information is allocated to a front part of a first arranged physical layer zone in the frame.

6. An apparatus for transmitting data comprising a plurality of data streams in a broadcasting system, the apparatus comprising:

a scheduler for dividing a frame into a plurality of physical layer zones, allocating the plurality of data streams to at least one of the plurality of physical layer zones, and allocating signaling information associated with the plurality of physical layers to at least one of the plurality of physical layer zones; and

a transmitter for transmitting the frame to which the signaling information is allocated.

7. The apparatus of claim 6, wherein the signaling information comprises at least one of locations of the physical layer zones, characteristics of the physical layer zones, and allocation information of the data streams with respect to the physical layer zones.

8.
