The number of barcode frames varies according to the size of the data.

The above-described barcode frame is obtained by dividing the original data into a predetermined size by dividing the original data into bar codes, which can be achieved as a 2D barcode frame or a color 2D barcode frame, which is expressed in one still image, that is, one barcode frame. One symbol can represent 500 characters, and the size of the symbol can range from 1 cubic millimeter to 14 cubic inches.

In addition, a bar code frame requires a data restoration code for restoring to one original data after being decoded by a bar code decoding program. The bar code frame is achieved by a connection code consisting of several bits. In the frame nf, a start code and end code, which are special connection codes indicating the start barcode frame 1f and the last barcode frame nf, are added. In addition, it may be possible to include a decompression algorithm such as a Huffman coding or an arithmetic coding and an error detection algorithm such as a parity bit when applying one barcode frame.

For example, one bar code frame stores 20 Kbytes of data except the bar code frame connection code, and a bar code video produced to be played back at 30 frames per second can contain data of 0.6 Mbytes per second or 36 Mbytes per minute.

4 is a flowchart of a method for producing a 2D barcode video according to the present invention, which is performed in a computer storing a large amount of data to be produced as a 2D barcode video.

First, in step S11, original data to be produced, that is, large data such as mp3 or more of 5 Mbytes or more, is separated into pieces at predetermined intervals, that is, tens of Kbytes.

In the next step S13, a connection code is added to each of the separated pieces, and in step S15, each piece to which the connection code is added is converted into a barcode frame.

Subsequently, in step S17, each barcode frame is bundled at predetermined time intervals to produce one barcode video file.

The barcode video thus produced may be reproduced through a video playback medium such as a computer or a television.

On the other hand, according to the above-described method, by recording the produced barcode video with a mobile communication terminal equipped with a video recording function, it is possible to easily store a large amount of data to the mobile communication terminal. At the same time, shooting should stop. However, since this is difficult in reality, complete data transfer is possible by starting shooting before barcode video playback and stopping shooting after barcode video playback is completed. At this time, the barcode frames recorded from the start of recording to the start of barcode video playback and the frames recorded from the completion of barcode video to the time of recording stop are unnecessary frames for restoring the original data. This is achieved by checking the connection code of the frame nf. When the number of playback frames of the 2D barcode video to be reproduced is smaller than the number of frames taken by the mobile communication terminal, the same code is applied to the data when restoring the data.
