Abstract
A recording apparatus includes an MPEG encoder, and compressed data from the MPEG encoder and data of an index (a transfer rate and a necessary memory capacity for the transfer rate, or a transfer rate and a rate difference characteristic) are multiplexed and recorded on an optical disc. In a reproducing apparatus, a bit stream read from the optical disc is converted into variable bit rate data by a CD decoder and a CD-ROM decoder. The variable bit rate data is once stored in a system buffer, and then, supplied to an MPEG decoder from the system buffer. The index is extracted by a microcomputer which determines whether or not it is possible to reproduce the optical disc through comparison of the necessary memory capacity and a capacity of the system buffer. If not reproduced, the optical disc is ejected. In a case of simple reproduction, data stored in an output buffer is repeatedly outputted during a time that an operation of the MPEG decoder is suspended.
