Abstract
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.
Claims15
A method for writing data to a bar code symbol having limited capacity comprising:
- receiving a data file encoding a human perceivable signal;
- reducing the size of the data file;
- and
- bitmapping a 2D bar code symbol to include the reduced size data file.
A method for writing data to a bar code symbol having limited capacity comprising:
- receiving a data file;
- and
- optimizing at least one encoding parameter to fit at least a portion of the data file into a bar code symbol;
- wherein optimizing at least one encoding parameter includes selecting the at least one encoding parameter to fit a fixed symbol size.
A system configured to output a bar code symbol carrying audio data comprising:
- a memory configured to receive an audio data file;
- and
- a processor configured to optimize at least one encoding parameter to fit at least a portion of the audio data file into a bar code symbol;
- wherein optimizing at least one encoding parameter includes selecting the at least one encoding parameter to fit a fixed symbol size.
