Title: RECORDING MEDIUM, REPRODUCING DEVICE, AND INTEGRATED CIRCUIT
Abstract:
A reading unit reads an extent block from a recording medium in a reproducing device. A switch unit extracts a main view stream and a sub view stream from the extent block. The respective streams are stored in different read buffers. A decoding unit reads the respective streams from the respective read buffers and decodes the read streams. The time (t) required for the decoding unit to decode all data blocks in one extent block is greater than or equal to the total of the following three times (t1, t2, t3): the time (t1) required for the reading unit to read data blocks other than a data block at the head of the one extent block; the time (t2) required from when the reading unit finishes reading the end of the one extent block until the reading unit starts to read the head of the next extent block; and the time (t3) required for the reading unit to read a data block at the head of the next extent block.
