Patent number: 8522339Abstract: Hardware of a playback apparatus includes a drive and a decoder, and firmware of the playback apparatus accesses a BD-ROM loaded on a drive, 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 in advance. The benchmark score shows a turn-around time from when a processing request is made to the hardware via the firmware to when a response returns. Such a benchmark score is written into an application data area in the local storage when the firmware is initially executed.Type: GrantFiled: February 29, 2008Date of Patent: August 27, 2013Assignee: Panasonic CorporationInventor: Hidetaka Ohto
