1. A display apparatus comprising:
a signal receiver which receives a signal containing video data for displaying a series of frames; a first data extractor which extracts first caption data from the signal; a data acquirer which acquires second caption data based on the extracted first caption data; a second data extractor which extracts the video data from the signal; a buffering section which buffers the extracted video data; a synchronizer which synchronizes the acquired second caption data with a frame corresponding to relevant caption data among frames of the buffered video data; and a display which displays the frame synchronized with the second caption data, wherein the data acquirer comprises a communicator which transmits the first caption data to a server, connected to the display apparatus through a network, and receives the second caption data from the server.
