Method and apparatus for using a limited capacity portable data carrier

摘要

A method for reading and using partial data from a portable data carrier includes reading data from a portable data carrier, determining if any data is missing, and if any data is missing, restructuring the data for use, such as for running an audio decoder and expander. A method for writing data to a portable data carrier having limited capacity includes receiving a data file and optimizing at least one encoding parameter to fit at least a portion of the data file into the portable data carrier.
