Abstract: In one embodiment, the recording medium includes a data area storing moving picture data, and a navigation area storing navigation information for managing reproduction of the moving picture data. The navigation information includes a metadata indicator indicating whether metadata associated with the moving picture data exists. The metadata is additional information describing content of the moving picture data, and the navigation information includes linking information identifying metadata associated with the moving picture data if the metadata indicator indicates metadata associated with the moving picture data exists. The navigation area may also store a content reference that references the moving picture data associated with the metadata.

Abstract: A plasma display panel employs a voltage circuit having an input and an output, the voltage circuit configured for supplying a negative voltage for an electrode. The plasma display panel also employs a power supply that has a positive terminal and a negative terminal, where the negative terminal is connected to the input of the voltage circuit. The power supply is otherwise configured relative to the voltage circuit such that the voltage difference between the output and the input of the voltage circuit is fixed as a function of the power supply. By fixing this voltage difference, parasitic capacitance is minimized, power consumption and calorific value are reduced, and the plasma display panel operates in a more stable manner.
