Abstract

An apparatus for receiving service guide fragments is discussed. The apparatus includes a receiver to receive service guide fragments, the service guide fragments including a content fragment describing content data in broadcast services, the content fragment including a content element, the content element including an identification attribute of the content fragment, and a version attribute of the content fragment, the content fragment further including a PrivateExt element which is used for content level extensions, the PrivateExt element including a component element describing components in the content data, the component element including an audio component element, a video component element, and a closed caption component element, the audio component element describing a role of an audio component in the content data, the video component element describing a role of a video component in the content data, and the closed caption component element describing a role of a closed caption component in the content data; and a decoder to decode the service guide fragments, and a displayer to display service guide information on a screen. Further, the service guide information is represented based on timeline information, channel information for the broadcast services, and program information for the content data, and the channel information is displayed with capability information.

Claims

1. An apparatus for receiving service guide fragments, the apparatus comprising:

a receiver to receive service guide fragments,

the service guide fragments including a content fragment describing content data in broadcast services,
