Document Type and Number:
WIPO Patent Application WO/2017/068971
Kind Code:
A1
Abstract:
Data playback is performed in a mode determined on the basis of disk type information, which is recording data for a disk. A reading rate corresponding to the physical format of a disk and a reading rate corresponding to the disk type are compared, and when the rates are inconsistent, data read from the disk at the physical-format-corresponding rate is stored in a buffer, and data outputted from the buffer at the disk-type-corresponding rate is utilized to perform a playback process. When the physical format is BD-R or BD-RE and a logic format corresponds to BDMV-UHD, emulation playback is performed, which accompanies rate conversion that utilizes the buffer.
