Abstract

A method of retrieving audio data using a coded medium is provided in which first and second coded data printed on the coded medium is sensed using an image sensor, the first coded data being printed in a linear pattern and encoding a medium identifier linked to the audio data and the second coded data being printed in a two-dimensional pattern and encoding the medium identifier and data on a two-dimensional coordinate grid, the medium identifier is determined from the sensed first and second coded data using a processor in communication with the image sensor, and the audio data is retrieved using the determined medium identifier and the processor.

Claims

1. A method of retrieving audio data using a coded medium, comprising the steps of:

sensing first and second coded data printed on the coded medium using an image sensor, the first coded data being printed in a linear pattern and encoding a medium identifier linked to the audio data, the second coded data being printed in a two-dimensional pattern and encoding the medium identifier and data on a two-dimensional coordinate grid;

determining the medium identifier from the sensed first and second coded data using a processor in communication with the image sensor; and

retrieving, using the processor, the audio data using the determined medium identifier.

2. The method as claimed in claim 1, wherein the image sensor is used to link the audio data to the medium identifier.

3. The method as claimed in claim 1, wherein the second coded data further encodes a digital signature associated with the medium identifier, the method including:

determining, by sensing at least some of the second coded data using the image sensor, the digital signature; and

retrieving, if the digital signature is authentic, the audio data.

4. The method as claimed in claim 3, wherein the digital signature includes at least one of:

a random number;

a secret-key digital signature; and

a public-key digital signature.

5. The method as claimed in claim 1, wherein the audio data is associated with a region of the coded medium, the method including:

sensing, using the image sensor, the second coded data;

determining a position of the image sensor relative to the coded medium from the two-dimensional coordinate grid information encoded by the sensed second coded data; and

retrieving, if the determined position is within the region, the audio data.

6. The method according to claim 1, wherein the first coded data is printed on one face of the coded medium and the second coded data is printed on an opposite face of the coded medium.

7. The method as claimed in claim 1, wherein:

the image sensor is incorporated in a media feed path of a mobile telecommunications device; and

the sensing step is performed when the coded surface is presented in the media feed path of the mobile telecommunications device.

8. The method as claimed in claim 7, wherein the media feed path includes a printer of the mobile telecommunications device.

9. The method as claimed in claim 1, wherein the printer prints at least some of the first and second coded data on the coded medium.
