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:
dividing the media data into at least one partial media data;
allocating the at least one partial media data to at least one transmission frame included in a superframe;
configuring the at least one transmission frame and a future extension frame (FEF) as the superframe, so that a summation of a time length of the at least one transmission frame and a time length of the FEF corresponds to the time length of the media data; and
transmitting the superframe to which the media data are allocated,
wherein the media data are not loaded on the FEF and the media data are loaded on the at least one transmission frame.

2. 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).

3. 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).

4. A device for transmitting media data in a digital broadcasting system, comprising:
a frame configurer for dividing the media data into at least one partial media data, allocating the at least one partial media data to at least one transmission frame included in a superframe, and configuring the at least one transmission frame and a future extension frame (FEF) as the superframe, so that a summation of a time length of the at least one transmission frame and a time length of the FEF corresponds to the time length of the media data; and
a transmitter for transmitting the superframe to which the media data are allocated, wherein the media data are not loaded on the FEF and the media data are loaded on the at least one transmission frame.

5. The device of claim 4 , wherein the superframe includes two transmission frames, and the media data are video data of thirty frames per second (fps).

6. The device of claim 4 , wherein the superframe includes three transmission frames, and the media data are video data of sixty frames per second (fps).

7. 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:
divide the media data into at least one partial media data;
allocate the at least one partial media data to at least one transmission frame included in a superframe;
configure the at least one transmission frame and a future extension frame (FEF) as the superframe, so that a summation of a time length of the at least one transmission frame and a time length of the FEF corresponds to the time length of the media data; and
transmit the superframe to which the media data are allocated, wherein the media data are not loaded on the FEF and the media data are loaded on the at least one transmission frame.

8. 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).

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