Abstract

The present invention provides a method for transmitting a broadcast signal. A method for transmitting a broadcast signal, according to one embodiment of the present invention, comprises the steps of: generating service guide information, which includes information for accessing a broadcast service, and content data, wherein the service guide information includes a service fragment which displays information related to the content data, and wherein the content fragment includes a component element which displays information related to a component included in the content data; encoding the service guide information and the content data which have been generated; and transmitting the service guide information and the content data which have been encoded.

Claims

1. A method for transmitting service guide fragments, the method comprising:

generating service guide fragments which are used to announce information regarding broadcast services,

wherein one of the service guide fragments is a content fragment describing content data in the broadcast services,

wherein the content fragment includes a content element, the content element including an identification attribute of the content fragment, and a version attribute of the content fragment,

wherein the content fragment further includes a PrivateExt element which is used for content level extensions,

wherein the PrivateExt element includes a component element describing components in the content data,

wherein the component element includes an audio component element, a video component element, and a closed caption component element,

wherein the audio component element describes a role of an audio component in the content data,

wherein the video component element describes a role of a video component in the content data, and

wherein the closed caption component element describes a role of a closed caption component in the content data; and

transmitting the service guide fragments.

2. The method of claim 1, wherein the component element further includes an application element describing a role for an application component in the content data.

3. The method of claim 1, wherein the role for the video component element represents one of a primary video, an alternative camera view, an other alternative video component, a sign language inset, a follow subject video, a three dimensional (3D) video left view, a 3D video right view, 3D video depth information, a part of video array <

x, y>

of <

m, n>

, and a follow subject metadata.

4. The method of claim 1, wherein the role for the audio component element represents one of music, dialog, effects, visually impaired, hearing impaired, and commentary.

5. The method of claim 1, wherein the role of the closed caption component elements represents one of normal and easy reader.

6. An apparatus for transmitting service guide fragments, the apparatus comprising:

a generation unit to generate service guide fragments which are used to announce information regarding broadcast services,

wherein one of the service guide fragments is a content fragment describing content data in the broadcast services,

wherein the content fragment includes a content element, the content element including an identification attribute of the content fragment, and a version attribute of the content fragment,

wherein the content fragment further includes a PrivateExt element which is used for content level extensions,

wherein the PrivateExt element includes a component element describing components in the content data,

wherein the component element includes an audio component element, a video component element, and a closed caption component element,

wherein the audio component element describes a role of an audio component in the content data,

wherein the video component element describes a role of a video component in the content data, and

wherein the closed caption component element describes a role of a closed caption component in the content data; and

a transmitter to transmit the service guide fragments.

7. The apparatus of claim 6, wherein the role for the video component element represents one of a primary video, an alternative camera view, an other alternative video component, a sign language inset, a follow subject video, a three dimensional (3D) video left view, a 3D video right view, 3D video depth information, a part of video array <

x, y>

of <

m, n>

, and a follow subject metadata,

wherein the role for the audio component element represents one of music, dialog, effects, visually impaired, hearing impaired, and commentary, and

wherein the role of the closed caption component element represents one of normal and easy reader.

8. The apparatus of claim 6, wherein the component element further includes an application element describing a role for an application component in the content data.
