Abstract:
1. A method of reproducing a digital broadcast performed by an apparatus supporting a plurality of compression formats, the method comprising: receiving a transport stream of the digital broadcast which is provided in one of the plurality of compression formats; 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, wherein the metadata includes information on at least one of a header, an intra picture, a reference picture, and a non-reference picture, wherein the extracting the metadata from the original stream comprises checking whether the transport stream is in a first compression format of the plurality of compression formats or in a second compression format of the plurality of compression formats, and if the transport stream is in the first compression format, the intra picture is a first type of intra picture, the reference picture is a first type of reference picture, and the non-reference picture is a first type of non-reference picture, and if the transport stream is in the second compression format, the intra picture is a second type of intra picture, the reference picture is a second type of reference picture, and the non-reference picture is a second type of non-reference picture.
