Method and system for transmission of information

A method for capturing and decoding visually transmitted and repeatedly updated information, the method comprising:

• repeatedly performing the following set of actions:
• capturing, by a digital image sensor, an image of a display including at least two information carrying patterns of different color,
• extracting from the captured image the information carrying pattern of a first color,
• decoding information from the extracted information carrying pattern of the first color,
• extracting from the captured image the information carrying pattern of a second color, and
• decoding information from the extracted information carrying pattern of the second color.

A system including an image capturing device and a display device, wherein the display device is arranged to display repeatedly updated information by repeatedly performing the following set of actions:

• receiving a first set of information to transmit, wherein the first set of information is an update of a previously received set of information,
• generating an information carrying first pattern representing the first set of information,
• displaying the information carrying first pattern in a first color,
• receiving a second set of information to transmit, wherein the second set of information is an update of the first set of information,
• generating an information carrying second pattern representing the second set of information,
• displaying the information carrying second pattern in a second color, wherein the second color differs from the first color, and
• wherein one of the information carrying patterns is statically displayed when another one of the information carrying patterns is updated;
• and
• wherein the image capturing device is arranged to capture and decode the displayed and repeatedly updated information by repeatedly performing the following set of actions:
• capturing, by a digital image sensor, an image of a display including at least two information carrying patterns of different color,
• extracting from the captured image the information carrying pattern of a first color,
• decoding information from the extracted information carrying pattern of the first color,
• extracting from the captured image the information carrying pattern of a second color, and
• decoding information from the extracted information carrying pattern of the second color.
