Recorded medium reproducing device and method, data output controlling method, data outputting method, error detecting method, and data outputting reproducing method

摘要

A reproducing method for a record medium, the reproducing method comprising the steps of performing a demodulating process for data that has been read from a record medium on which data of a content has been recorded, at least management information and additional information being embedded to the data of the content, the management information being with respect to a copy management, the additional information containing at least one of error detection code and error correction code added to the management information, detecting the additional information from an output signal of which the demodulation process has been performed, performing an error detecting process corresponding to one of the error detection code and the error correction code of the detected additional information, and controlling an output operation for an output signal of which the demodulating process has been performed for the data of the content that has been read from the record medium corresponding to the management information when no error takes place in the error detecting process.
