The video data comprises at least a high resolution video data and a corresponding low resolution video data. A second reproducer is also provided for reproducing a texture image data and a key data for keying the reproduced video data from a second recording medium in which the texture image data and the key data are recorded in accordance with the same recording format as the data recording format. The texture image data comprises at least a high resolution texture image data and an associated low resolution texture image data. The key data comprises at least a high resolution key data and an associated low resolution key data. A synthesizer for synthesizing the high resolution video data and the high resolution texture image data based on the high resolution key data and for synthesizing the low resolution video data and the low resolution texture image data based on the low resolution key data.
