Abstract

Disclosed is an apparatus and method for data transmission/reception for transmitting/receiving data, which can transmit and receive data by using a transmitter (display device) capable of receiving and displaying digital data, and a receiver capable of receiving digital data by photographing the digital data. The apparatus includes a transmitter for receiving and displaying digital data; and a receiver for photographing and receiving the digital data displayed in the transmitter, and restoring the received digital data, thereby restoring corresponding data information. The method includes receiving and displaying digital data by a transmitter; and photographing and receiving the digital data displayed in the transmitter, and restoring the received digital data and displaying a corresponding data by a receiver.

Claims
