Abstract:
1. A playback device for playing back an optical recording medium in which a stream and a program connecting to a data-supplying source corresponding to the stream through a network are recorded, and two playback paths are provided: a first path corresponding to a network corresponding mode in which the data of the stream is played back referring to the data supplied from the data-supplying source, and a second path corresponding to a network non-corresponding mode in which the data of the stream is played back without referring to the data supplied from the data-supplying source, the playback device comprising: a network-circuit-information acquiring unit that reads out, before playing back data of the stream recorded on the optical recording medium, information on the program corresponding to the stream and then outputs on the basis of the read-out information a connection condition signal concerning connection condition through the network between the playback device and the data-supplying source corresponding to the stream; a system control unit that outputs a determination signal representing whether or not to connect to the data-supplying source through the network on the basis of the connection condition signal; and a data playback unit that plays back the data of the stream using the first playback path of the network corresponding mode when the determination signal indicates that the data-supplying source is connected through the network, and using the second playback path of the network non-corresponding mode when the signal indicates that the data-supplying source is not connected through the network.
