Abstract:
PURPOSE: A content providing device for connecting content streaming in a fusion type 3DTV, a method thereof, a content reproduction device thereof, and a method thereof are provided to connect the content streaming related to a reference image for the fusion type 3DTV and the content streaming related to an additional image. CONSTITUTION: A content stream generation unit(303) generates first content stream corresponding to a reference image and second content stream corresponding to an additional image. A descriptor generation unit(304) generates a descriptor related to the first content stream and the second content stream. A data transmission unit(305) transmits the first content stream, the second content stream, and the descriptor to a content reproduction device(302).

Abstract:
PURPOSE: An image providing device, a method, an image reproduction device, and a method are provided to more efficiently restore a right image of low resolution than a left image of high resolution. CONSTITUTION: An image identifying unit(201) identifies a reference image of high resolution and an additional image of low resolution. A restoration mode determination unit(202) determines a restoration mode of the additional image of the low resolution. A data transmission unit(203) transmits additional information including the reference image of the high resolution, the additional image of the low resolution, and the restoration mode.

PURPOSE: A content reproducing device, a method, a content providing device, and a method for synchronizing left/right streams in a fixed and moved fusion type of a 3D TV are provided to synchronize a left image and a right image in a 3D TV broadcast. CONSTITUTION: A synchronization information generation unit(203) generates time stamp pair to synchronization information. The time stamp pair includes a time stamp corresponding to an access unit of a left image and a time stamp corresponding to an access unit of a right image. A synchronization information multiplexing unit(204) multiplexes the synchronization information to signaling information.

Abstract:
PURPOSE: A content providing device, a method, a content reproducing device, and a method for synchronizing left and right streams in a fixed and moved fusion type of a 3D TV are provided to perform demultiplexing restoration of synchronization information, thereby performing audio synchronization and video synchronization between timing models of a left image and a right image. CONSTITUTION: A content providing device generates synchronization information for coinciding reproduction time between access units of a left image and a right image(801). The content providing device transmits a main content stream of the left image and an additional content stream of the right image to a content reproducing device. The content providing device multiplexes the synchronization information by inserting the synchronization information to the main content stream or signaling information of the additional content stream(802).
