Abstract
Provided are a method and apparatus for reproducing a digital broadcast having different compression formats and a method of recording the digital broadcast so that the digital broadcast may be consistently stored and reproduced regardless of a compression format of the digital broadcast. The method of reproducing a digital broadcast includes receiving a transport stream of the digital broadcast which is provided in a compression format; extracting an original stream of a desired program by demultiplexing the transport stream and extracting metadata from the original stream for reproducing or performing trick-play functions on the original stream; separately storing the original stream and the metadata; and decoding the original stream in accordance with the compression format and displaying the original stream. The method and apparatus allows a user to consistently perform functions on the digital broadcast regardless of a compression format of the digital broadcast.
