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).

Abstract:
PURPOSE: A synchronization method for implementing a 3D service in ATSC-M/H is provided to adjust synchronism between a TS(transmission stream)-M stream and an M/H stream. CONSTITUTION: A TS inputted to a dual stream through a receiver is separated into a TS-M stream and a M/H stream through an inverse multiplexer. Each of timing models is analyzed to adjust synchronism between streams including two different timing models and to find reference information shared between the timing models. Synchronization between heterogeneous streams is performed based on PTS(Presentation Time Stamp) information generated through a wall-clock. A 3D image is formed through the synchronization by using the heterogeneous streams having the same time synchronism.

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.
