Benefits of technology
The device reduces the likelihood of unnecessary user operations by determining network readiness before playback, ensuring smooth operation even when network connectivity is compromised, and preventing playback disruptions due to network issues.
Problems solved by technology
However, it is not disclosed about how to deal with such cases when the network cannot be used (for example, “disconnection of the network cable”, “no destination content in the network”, and “an extremely slow communication speed due to heavy traffic on the network circuits”).
In addition, in the technique, such cases when a network circuit itself does not effectively function—for example, when the network cable is disconnected or when no setting operations are performed for the network connection—are not taken into consideration.

embodiment 1
[0088]In Embodiment 1, a playback device 100 will be explained, in which, when the playback device cannot use a network circuit but plays back an optical disk including a program having a function to connect to the network, the device notifies in advance its users that network contents cannot be used, so that the device can prevent them from operating actually unnecessary operations.
[0089]Note that hereinafter, “being unable to use network contents” means a condition that “network circuits cannot be used normally”, for example, a condition that the network cable is broken, a condition that the network configuration of the playback device itself is not appropriately performed, a condition that the network load is extremely high, and a condition that there exists no destination content.
[0090]FIG. 1 is a block diagram representing a system configuration of Embodiment 1 according to the present invention. In the figure, a system control unit 101 integrally controls the entire playback d...

To play back an optical disk requiring network connection, a playback device is provided, which has a function by which the network condition is evaluated before playing back a title. The playback device plays back the optical disk including programs connecting through the network to data-supplying sources; the playback device determines whether or not the network circuit is available; and when the network connection is not available depending on a network connection status or its memory amount, the playback device plays back with a non-network-ready mode.
Description
TECHNICAL FIELD[0001]This application is a Divisional of co-pending application Ser. No. 12 / 226,685, filed on Oct. 24, 2008, the entire contents of which are hereby incorporated by reference and for which priority is claimed under 35 U.S.C. §120.[0002]The present invention relates to playback devices that play back information recorded on an optical recording medium; it especially relates to a playback device for an optical recording medium on which a program realizing an interactive function is recorded to be executed in order that online network contents (data) can be downloaded.BACKGROUND ART[0003]DVD standards have been known for devices that play back stream information recorded on optical disks. On the other hand, the devices that meet with the standards for next-generation optical disks such as BD (Blu-ray Disc standards) and HD-DVD standards cannot only play back stream information thereon, but also execute programs recorded on the optical disks. The programs are recorded to...
