In one embodiment, the method includes determining a secondary video stream to reproduce with a primary video stream based on management information stored in a memory. The secondary video stream represents the picture-in-picture presentation path with respect to a primary presentation path represented by a primary video stream. The management information includes identifying information identifying the secondary video stream to reproduce, and the management information includes display information indicating whether to display the secondary video stream. The determined secondary video stream is selectively reproduced based on the management information.
