Title: Transcoding apparatus, method and medium

Abstract: A transcoder is provided for converting copyright information. The transcoder includes a separator configured to extract a video transport stream packet including a first video stream having copyright information, a non-video transport stream packet, and timing information from a first transport stream. A memory stores the timing information. The conversion unit generates a second video stream from the first video stream by converting the copyright information. A multiplexer multiplexes a video transport stream packet including the second video stream and the non-video transport stream packet based on the stored timing information to generate a second transport stream.
