Signal processing on information files so as to obtain characteristic point information sequences

摘要

An apparatus for recording a digital information signal in the form of an information file on a record carrier includes input apparatus for receiving the digital information signal, processing apparatus for processing the digital information signal into an information file, and writing apparatus for writing the information file on the record carrier in sections having a predetermined memory size. The apparatus further includes apparatus for generating characteristic point information (CPI) for inclusion in a CPI sequence. The characteristic point information identifies a characteristic point in the information file. The CPI sequence is formatted and CPI information for several CPI sequences is shared.
