摘要

A minimum buffer data amount and a minimum reproduction delay time are found from a line approximation graphic form approximating a media read line and used as a basis for determining whether or not data can be reproduced in a real-time manner from a recording medium at a requested reproduction rate. The media read line is a line expressing the change in cumulative amount of data read out from the recording medium. The minimum buffer data amount is the minimum of the amount of data stored in a buffer as data required in reproduction of the data in a real-time manner at the requested reproduction rate. The minimum reproduction delay time is the minimum of a reproduction delay time from the start of an operation to read out the data from the recording medium to the start of an operation to reproduce the data.
