Abstract: Provided are a three-dimensional (3D) stereoscopic digital broadcasting transmitting/receiving apparatus and method using 3D stereoscopic video additional data. The apparatus and method is compatible with a two-dimensional (2D) digital broadcasting system by defining and processing 3D stereoscopic video additional data, such as another 3D video, disparity information, and depth information, as an additional stream added to a 2D video transport stream, which is different from the conventional method that provides a 3D stereoscopic digital broadcasting system by using video of another viewpoint. The 3D stereoscopic digital broadcast transmitting apparatus includes: a video acquiring unit; an audio data acquiring unit, an encoding unit, a program specific information (PSI) generating unit, a packetizing unit, a transport stream (TS) generating unit, a multiplexing unit, and a modulating unit.

Abstract: Provided is a resource management apparatus for a data broadcast receiving device that can make an application use resources efficiently by categorizing one or more resources into an essential group and an optional group and managing and distributing them on a group basis, and clearly control and distribute resources requested essentially or optionally by a predetermined application based on a policy, and a method thereof . The apparatus includes a resource request receiving unit for receiving the request for resources required by an application on a group basis; and a resource distributing unit for distributing the resources corresponding to the group unit to the application.
