    Abstract: A method and apparatus for receiving a broadcast service in a digital broadcasting system. The method includes receiving, by a reception unit, related information relevant to a common broadcast service being provided in common in at least two Internet Protocol (IP) platforms, from one of the at least two IP platforms; determining, by a mobility management block, whether a currently received broadcast service is the common broadcast service, based on the related information; and continuously receiving the common broadcast service from a remaining IP platform, except for the one of the at least two IP platforms, when the currently received broadcast service is the common broadcast service.

    Abstract: A method and an apparatus for processing a media file for an augmented reality service are provided. The method includes analyzing at least one media file including a marker track and a virtual object track to be used for providing the augmented reality service; generating image data needed for reproducing an image by extracting video data and/or audio data included in the media file; generating virtual object data for displaying a virtual object by extracting virtual object information included in the media file; and synthesizing the image data and the virtual object data based on the marker track to structure a final image and reproducing the final image on a screen.

    Abstract: A method and apparatus of processing data to support Augmented Reality (AR) are provided. In the method, an image file including at least a scene description stream, an object descriptor stream, and a visual stream including a real-world medium is received, the scene description stream including an AR node that represents information about at least one piece of AR content used to augment the real-world medium, information about an AR locator and an object descriptor Identifier (ID) is acquired from the AR node, the AR locator describing when the at least one piece of AR content appears and how the real-world medium is augmented with the at least one piece of AR content and the object indicator ID identifying an Object Descriptor (OD) that describes the at least one piece of AR content, and at least one elementary stream descriptor.
