<p>Hardware of a playback apparatus 102 includes a drive 1 and a decoder, and firmware 22 of the playback apparatus 102 accesses a BD-ROM loaded on a drive 1, according to a BD-J application, to bring the decoder into AV playback operations. The drive unit constitutes a local storage. A benchmark score is built in the firmware 22 in advance. The benchmark score shows a turn-around time from when a processing request is made to the hardware via the firmware 22 to when a response returns. Such a benchmark score is written into an application data area in the local storage when the firmware 122 is initially executed.</p> |
