Abstract

PURPOSE:To shorten a data transmitting time, and to save a cost by transmitting pattern data through binary to hexadecimal conversion, at the time of transmitting data expressed by 0 and 1 to the other party by a character form. CONSTITUTION:Transmission data are, for example, 24 digit data, that is 24 bite data, and when the data are transmitted in the original form, 24X8 bit data amounts are obtained. At that time, the transmission data are divided into 8 digit units, and the divided 8 digits are divided into 4 digit units. Then, the data expressed by 0 and 1 of each 4 digit are converted from binary data into hexadecimal data, and converted into each 1 digit. That is, the 24 digit data are condensed into the 6 digit information. Thus, the binary pattern data expressed by 0 and 1 on transmission are hexadecimal converted, so that the number of digits of a bit can be decreased so as to be 1/4 times. Then, a step at a transmission side is inverse-transformed at a reception side, so that reception data can be decoded.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a data condensing method, in particular 0,
The present invention relates to a data condensing method when a large amount of data represented by 1 is transmitted to a partner node in a character format.

[0002]

2. Description of the Related Art Generally, when transmitting 1000 bytes of 0,1 representation data to a node that receives data in character format, 1000 bytes of information will be transmitted during the transmission.

As described above, according to the conventional data transmission method, even when the content of the data is simple information such as 0 or 1, the data on the transmission line flows in proportion to the number of data, so that a large amount of data is transmitted. In this case, there is a problem that the transmission time of data becomes long and the transmission cost becomes large.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention has been made to solve the above-mentioned problems of the prior art. The purpose of the present invention is to reduce the data transmission time and reduce the cost. It is to provide a method of condensing data.

[0005]

According to the present invention, there is provided a method of condensing transmission data when transmitting data represented by 0 and 1 in a character format to a destination, wherein the data is divided into four digits. And a step of converting the data for each one segment into hexadecimal notation, and transmitting the converted data.

[0006]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing stepwise an example of a data condensing method according to an embodiment of the present invention. (A) is an example of data to be transmitted, and this example shows a case of 24-digit data. Each digit is data of 0, 1 representation, and each digit is assumed to consist of 1 byte (8 bits).

Therefore, the transmission data of (a) is data of 24 digits, that is, 24 bytes, and if it is transmitted in the same format, the data amount is 24 × 8 bits.

Therefore, in the present invention, as shown in FIG.
Divide each digit into 8 digits and divide each 8 digits into 2 4 digits
Divide into two. Then, each of these 4-digit 0, 1 expressions is converted from binary to hexadecimal to be each 1-digit as shown in (c).

When the 24-digit data shown in (a) is converted to this method, it is condensed into 6-digit information as shown in FIG. In this way, by converting the binary pattern data represented by 0 and 1 on the transmission into hexadecimal, the number of bits can be reduced to 1/4.

On the receiving side, as shown in FIG.
By performing the inverse conversion process in step (c), the received data can be decrypted.

The above embodiment is merely an example for the purpose of explanation, and it goes without saying that various modifications can be made.

[0013]

As described above, according to the present invention, since binary pattern data is converted into hexadecimal and transmitted, the number of bit digits can be reduced and the transmission time during online is shortened. There is an effect that the cost can be reduced.
