Abstract

An apparatus and method for transmitting a broadcast signal, an apparatus and method of reproducing a broadcast signal, and a broadcast signal data structure, are discussed. According to an embodiment, the method of transmitting the broadcast signal includes generating image modification control information for at least one image; and transmitting the image and the image modification control information as broadcast data.

Claims

1. In a broadcast receiver configured to receive a broadcast data, a method of reproducing the broadcast data, comprising:

receiving, by the broadcast receiver, the broadcast data including an image group of images, an image transition effect table, and image reproduction control information from a broadcast transmitter,

wherein the image reproduction control information comprises;

image scene change control information for arranging the images in a specific sequence,

dimension information for the received image group, the dimension information indicating whether a reproduction dimension of the images in the image group is a 3-D reproduction dimension or a 2-D reproduction dimension,

when the received image group is indicated as having a 3-D reproduction dimension, image information for each received image in the received image group, the image information indicating whether a corresponding image is a left image or a right image of a 3-D image, and

additional information for modifying a form, a color, a brightness, an opacity, or a motion of the received images;

modifying, by the broadcast receiver, the received images based on the corresponding dimension information and the additional information;

storing the modified images in a 2-D form, a 3-D form, a 2-D group form, or a 3-D group form according to the image reproduction dimension;

arranging, by the broadcast receiver, the stored images in the specific sequence by using the image transition effect table and the image scene change control information; and

outputting, by the broadcast receiver, the arranged images.

2. The method of claim 1, wherein the image scene change control information includes interval change information for changing intervals between the images.

3. The method of claim 1, wherein, when the dimension information indicates that the reproduction dimension of the received images is 2-D, the modified images are output as 2-D images.

11. The method of claim 1, wherein the image reproduction control information further includes:

information indicating a count of the received images included in the image group,

information indicating a serial number of the received images included in the image group,

information indicating a reproduction interval between a plurality of image groups, and

information indicating a group serial number of the image group.

4. An apparatus for reproducing broadcast data, comprising:

a receiving unit configured to receive the broadcast data including an image group of images, an image transition effect table, and image reproduction control information from a broadcast transmitter,

wherein the image reproduction control information comprises;

image scene change control information for arranging the images in a specific sequence,

dimension information for the received image group, the dimension information indicating whether a reproduction dimension of the images in the image group is a 3-D reproduction dimension or a 2-D reproduction dimension,

when the received image group is indicated as having a 3-D reproduction dimension, image information for each received image in the received image group, the image information indicating whether a corresponding image is a left image or a right image of a 3-D image, and

additional information for modifying a form, a color, a brightness, an opacity, or a motion of the received images;

a control unit configured to modify the received images based on the corresponding dimension information and the additional information, and to arrange the stored images in the specific sequence by using the image transition effect table and the image scene change control information;

a memory unit configured to store the image group and the image reproduction control information,

wherein the memory unit stores the modified images in a 2-D form, a 3-D form, a 2-D group form, or a 3-D group form according to the image reproduction dimension; and

a display unit configured to output the arranged images.

5. The apparatus of claim 4, wherein the image scene change control information includes interval change information for changing intervals between the received images.

6. The apparatus of claim 4, wherein, when the dimension information indicates that the reproduction dimension of the received images is 2-D, the modified images are output as 2-D images.

7. The apparatus of claim 5, wherein the control unit operates an image transition effect table corresponding to scene change control information included in the image reproduction control information.

8. The apparatus of claim 7, wherein the control unit updates the image transition effect table using the received broadcast data.

9. The apparatus of claim 6, further comprising:

a switching panel for performing a 3-D display or a 2-D display,

wherein the switching panel is turned off if the dimension information indicates that the reproduction dimension of a received image is 2-D, and

wherein the switching panel is turned on to disperse an incident angle if the dimension information indicates that the reproduction dimension of a received image is 3-D.

10. The apparatus of claim 4, wherein the apparatus is a TV or a mobile communication terminal.

12. The apparatus of claim 4, wherein the image reproduction information further includes:

information indicating a count of the received images included in the image group,

information indicating a serial number of the received images included in the image group,

information indicating a reproduction interval between a plurality of image groups, and

information indicating a group serial number of the image group.
