Abstract
A system and method for transmitting visual data by displaying a synchronization video that includes synchronization code sequences on a first device, capturing the synchronization video using a video camera of a second device, parsing and decoding the synchronization code sequences on the second device, displaying an indication of which of the synchronization code sequences are compatible for visual data transmission on the second device, receiving a selected synchronization code sequence of the synchronization code sequences on the first device, and displaying a data code sequence corresponding to the selected synchronization code sequence on the first device, wherein the data code sequence includes encoded data, and capturing and decoding the data code sequence on the second device.
