An apparatus and a method of arbitrarily adjusting the output time of caption information included in a received multimedia transport stream for broadcasting, by user input. The method includes: receiving an input of a time value for adjusting the output time of caption information, from a user through a user interface; by demultiplexing the multimedia transport stream, dividing the transport stream into video, audio, and data packets, decoding each packet, and storing the decoded packets in buffers corresponding to a type of each packet; resetting the output time of the caption information by adding the input time value to or subtracting the input time value from the output time included in the video or audio packet; and according to the output time of the reset caption information, blending the data stored in the buffer with the video information and presenting the blended information on the screen.

Method of controlling ouput time and output priority of caption information and apparatus thereof

An image segmentation method including: selecting a region of interest including an object whose image is to be segmented; detecting the edge of the object; repeatedly performing, until a specified precision is obtained, a process in which by using a layered mesh structure based on the detected edge, a mesh boundary of the object is detected, a mesh size is reduced by one layer, and then by using areas adjacent to the detected mesh boundary, correcting the mesh boundary; and generating a mask to fill a inside area of the correcting mesh boundary and masking the object.
