A recorder player (100) has a first encoder (4) for encoding broadcast video signals at a first image quality, a second encoder (14) for encoding the same video signals as those encoded by the first encoder (4) at a second image quality, which is lower than the first image quality, and a recording and reproducing unit (6) for recording and reproducing data which is encoded by the first encoder (4) and backup data which is encoded by the second encoder (14).
