Abstract
The system controller sequentially reads the interleaved units (ILVU) corresponding to all the angles to store them in the RAM as the track buffer. When the angle switching is instructed, the system controller reads the ILVU corresponding to the angle after switching, out of the angle block next to the angle block which the ILVU that was read at the moment of the switching instruction from the RAM and is a decoding object belongs to, and controls the reproduction. Further, when the angle switching is instructed, the system controller judges whether it is possible to replace the ILVU before the angle switching stored in the RAM by the ILVU after the angle switching, while maintaining a state of the reproduction image being not intermittent. When it is replaceable, the system controller reads the ILVU after the angle switching from a DVD to store it in the RAM, and thereby replaces the ILVU. Thus, the disk reproduction device achieves a quick angle switching in the multi-angle reproduction operation.
