Abstract:
A 3D position input method, an apparatus thereof are provided to perform the 3D position input by using a 2D input device. It is determined whether a control signal for moving a pointer which is placed at a point on a 2D coordinate surface is a 3D moving signal for moving the pointer into the 3D space(S610). It is determined whether the control signal corresponds to the movement of the pointer according to a predetermined path(S612). It is determined whether the control signal corresponds to the movement of the pointer within a threshold range(S614). The pointer is selectively moved to the point in the 3D space(S620).

A method and an apparatus for generating a stereoscopic image data stream for partial data interval reproduction of an stereoscopic image and a method and an apparatus for reproducing partial data of a stereoscopic image are provided to generate a stereoscopic image data stream including a parameter about a stereoscopic image in order to automatically select a single time image to be reproduced. A mono scopic image data interval determining unit(510) determines mono scopic image data intervals among image data intervals of a stereoscopic image data stream. A CTS(Composition Time Stamp) extracting unit(520) extracts a CTS of the mono scopic image data intervals. A collision monoscopic image data extracting unit(530) extracts mono scopic image data from the mono scopic image data interval of a main stream among collision image data intervals.
