description An information reproducing apparatus reproduces one type of information (for example, video information) in synchronous with a plurality of channels of other type of information (for example, audio information) with high copyright protection, and includes a decryption section that decrypts multiplexed stream reproduced from a recording medium, a stream analyzer that analyzes the multiplexed stream which is decrypted to detect first information (video information) contained in the multiplexed stream, a stream conversion section that alters the first information contained in the multiplexed stream which is decrypted, based on an analysis result by the analyzer. The multiplexed stream with altered video information is distributed to second to n-th stream decoders (for example, for achieving a multilingual system).
