Abstract
Data transmission apparatus and method thereof, and data reception apparatus and method thereof. Input data is encoded into a plurality of visual codes according to a visual code type. The visual code type includes a sequential type requiring sequential transmission and a nonsequential type not requiring sequential transmission. The sequential visual code includes start code, data code, and end code, and is displayed sequentially. The nonsequential visual code is displayed nonsequentially.
Claims13
A data transmission apparatus, comprising:
- an encoder configured to divide input data and encode the divided data into a plurality of visual code images based on whether a visual code transmission technique is a sequential transmission or a nonsequential transmission;
- and
- a display configured to display each of the plurality of visual code images during at least a minimum expression time based on the visual code transmission technique to enable the plurality of visual code images to be captured by a data reception apparatus.
A data transmission apparatus, comprising:
- an encoder configured to divide input data and encode the divided data into a plurality of visual code images according to a visual code type depending on a visual code transmission technique;
- and
- a display configured to display each of the plurality of visual code images during at least a minimum expression time to allow the plurality of visual code images to be captured by a data reception apparatus,
- wherein the visual code type comprises sequential visual code configured to perform sequential transmission, and nonsequential visual code configured to perform transmission which is not sequential, and
- wherein the encoder generates the visual codes to include a start code to identify a start of the encoded data, a data code to transmit data, and an end code to identify an end of the encoded data, and
- the respective sequential visual codes comprise type recognition information to identify them as a sequential type.
