Abstract
When a disc loaded on a player is a hybrid next generation DVD, determination is made on whether the connected TV device is adaptable for the HD mode. Such determination is performed by whether or not the copyright protecting function of the connected TV device satisfies a condition set in advance. When adaptable for the HD mode, reproduction prioritizing the HDDVD layer is performed. When not adaptable for the HD mode, reproduction prioritizing the DVD layer is performed. Thus, the video content of HD mode recorded on the HDDVD layer is protected against leakage to the outside via the connected TV device by reproducing the DVD layer in preference in the case the copyright protecting function of the TV device is not sufficient.
