Abstract

Disclosed is a method and device for transmitting media data in a digital broadcasting system for allocating media data to a superframe, and transmitting a superframe in which a time length of media data corresponds to a time length of the superframe.

First claim

What is claimed is:

1 . A method for transmitting media data in a digital broadcasting system, comprising:
allocating the media data to a superframe; and transmitting the superframe to which the media data are allocated, wherein a time length of the superframe corresponds to a time length of the media data.

2 . The method of claim 1 , wherein
the superframe includes a future extension frame (FEF) on which the media data are not loaded, and at least one transmission frame on which the media data are loaded.

3 . The method of claim 2 , wherein
a summation of a time length of the at least one transmission frame and a time length of the FEF corresponds to a time length of the media data.

4 . The method of claim 1 , wherein
the superframe includes two transmission frames, and the media data are video data of 30 frames per second (fps).

5 . The method of claim 1 , wherein
the superframe includes three transmission frames, and the media data are video data of 60 frames per second (fps).

6 . The method of claim 1 , wherein
the allocating includes: dividing the media data into a plurality of partial media data; allocating the plurality of partial media data to a plurality of transmission frames included in the superframe based upon a time length of one of the plurality of partial media data; and configuring the plurality of transmission frames and a future extension frame (FEF) as a superframe.

7 . A device for transmitting media data in a digital broadcasting system, comprising:
a frame configurer for allocating the media data to a superframe; and a transmitter for transmitting the superframe to which the media data are allocated, wherein a time length of the superframe corresponds to a time length of the media data.

8 . The device of claim 7 , wherein
the superframe includes a future extension frame (FEF) on which the media data are not loaded, and at least one transmission frame on which the media data are loaded.

9 . The device of claim 8 , wherein
a summation of a time length of the at least one transmission frame and a time length of the FEF corresponds to a time length of the media data.

10 . The device of claim 7 , wherein
the superframe includes two transmission frames, and the media data are video data of thirty frames per second (fps).

11 . The device of claim 7 , wherein
the superframe includes three transmission frames, and the media data are video data of sixty frames per second (fps).

12 . The device of claim 7 , further comprising
a media transmitter for dividing the media data into a plurality of partial media data, wherein the frame configurer allocates the plurality of partial media data to a plurality of transmission frames included in the superframe based upon a time length of one of the plurality of partial media data, and configures the plurality of transmission frames and a future extension frame (FEF) as a superframe.

13 . A device for transmitting media data, comprising:
at least one processor; a memory; and a radio frequency (RF) unit, wherein the at least one processor performs at least one program included in the memory to allocate the media data to a superframe and transmit the superframe to which the media data are allocated, and a time length of the superframe corresponds to a time length of the media data.

14 . The device of claim 13 , wherein
the superframe includes a future extension frame (FEF) on which the media data are not loaded, and at least one transmission frame on which the media data are loaded.

15 . The device of claim 14 , wherein
a summation of a time length of the at least one transmission frame and a time length of the FEF corresponds to a time length of the media data.

16 . The device of claim 13 , wherein
the superframe includes two transmission frames, and the media data are video data of thirty frames per second (fps).

17 . The device of claim 13 , wherein
the superframe includes three transmission frame, and the media data are video data of sixty frames per second (fps).

18 . The device of claim 13 , wherein,
when performing the allocation, the at least one processor divides the media data into a plurality of partial media data, allocates the plurality of partial media data to a plurality of transmission frames included in the superframe based upon a time length of one of the plurality of partial media data, and configures the plurality of transmission frames and a future extension frame (FEF) as a superframe.
