The present invention provides an apparatus for transforming a terrestrial digital multimedia broadcasting (DMB) stream. The transformation apparatus includes a program specific information (PSI) extracting unit extracting PSI of a first stream and transmitting the first stream to a time code extracting unit a PSI analyzing unit analyzing the PSI of the first stream and acquiring construction information thereof; a PSI modifying unit for modifying the PSI information based on PSI modification information; the time code extracting unit for extracting time code information from the first stream based on stream information; a time code modifying unit for modifying a time code of a second stream based on the time code information; a stream erasing unit for erasing a stream piece of the first stream based on stream erasing information from the user; and a multiplexing unit for multiplexing the modified PSI, the modified first stream and the modified second stream. |
