Drawings
The invention will be further described with reference to the accompanying drawings and examples, in which:
FIG. 1 is a flow chart of a method according to a first embodiment of the present invention;
fig. 2 is a block diagram of the first embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
First embodiment
As shown in fig. 1, a first embodiment of the present invention provides an information conversion method, including the steps of,
s1, selecting some sound elements in the sound information as sound elements carrying information, and making the selected sound elements carrying information correspond to N-system data one by one to establish a first mapping table, wherein N is an integer greater than 2.
The sound element may be an element such as frequency or sound color in sound, or an element such as note and beat in music. In this step, the N-ary system is selected according to the number of the selected information-carrying sound elements in the sound information, for example, if the sound information is a music composed of a seventh scale, the music includes a plurality of sound elements, such as notes, beats, etc., we select 7 consecutive notes of the mediant as the information-carrying sound elements, the selected information-carrying sound elements are notes 1, 2, 3, 4, 5, 6, 7, for convenience of definition and calculation storage, the 7-ary system can be selected to correspond to each note, and the notes 1, 2, 3, 4, 5, 6, 7 can respectively correspond to the 7-ary data 3, 0, 5, 6, 2, 1, 4. Meanwhile, other treble and bass notes and rests are placed as separators between notes carrying information to ensure that no confusion occurs when decoding sounds.
S2, each character in the character information is in one-to-one correspondence with the binary data, and a second mapping table is established;
characters are all in the form of binary codes when processed by a computer. This collection of commonly used english alphabets, numbers and commonly used character binary codes is the so-called ASCII code. The basic ASCII code has 128 most significant digits all 0, and the corresponding decimal numbers are 0-127. Characters on the keyboard, such as english letters, numbers and some common symbols, use basic ASCII code parts. For example, the ASCII code of the number "0" is 00110000 (i.e., decimal number 48) in binary number. The expanded ASCII codes have 128, the highest bits are all 1, and the corresponding decimal number is 128-255. Some tabs and other symbols use an extended ASCII code portion. In order to solve the problems of storage and display of Chinese characters, China establishes a national standard GB2312, and one Chinese character consists of two expanded ASCII codes according to the regulation of the GB 2312. The double-byte Chinese character code with high order 1 is the machine internal code of Chinese character, which is called internal code for short. For example, the code in Chinese "learning" is 1101000110100111 (i.e., 209 and 167) in binary and 53671(209 × 256+167) in decimal. For characters, the computer stores and processes its ASCII code, and for chinese characters, the computer stores and processes its internal code, i.e., two-bit ASCII code. For example, the character string "0 math 0" is stored in the computer at 00110000110100011010011100110000. Thus, for each Chinese character, there are two unique extended ASCII codes corresponding. Similarly, there is a unique ASCII code correspondence in computers for other languages, thus creating a one-to-one correspondence between textual information and binary numbers. Of course, we can establish a new one-to-one correspondence relationship according to the rule established by themselves, and details are not described herein.
S3; carrying out one-to-one correspondence on binary data and N-ary data in the second mapping table to establish a third mapping table;
the correspondence between binary and N-ary belongs to the prior art, and is not described herein again.
S4, converting the character information into binary data through the second mapping table, converting the binary data into N-system data through the third mapping table, and converting the N-system data into sound information through the first mapping table for storage.
The method comprises the steps of converting character information into binary data, enabling the character information to be transmitted remotely through equipment such as a computer, processing the character information into sound information by utilizing a mapping relation between sound and information content, for example, selecting N to 7, selecting notes 1, 2, 3, 4, 5, 6 and 7 to correspond to numbers 3, 0, 5, 6, 2, 1 and 4 in a 7-system, and selecting other high-pitch and low-pitch notes and rest characters as separators to be arranged among notes carrying information so as to ensure that confusion does not occur during sound decoding. When the character information is input into ' a ', the character information is converted into 01100001 binary system, then the character information is converted into corresponding 166 7 binary system, and then the corresponding 166 binary system is saved by using the musical note ' 644 ', and for the character input ' aa ', the character information can be represented by the musical note ' 5760576 ', and can also be represented by the musical note '
"means. In addition, the voice information is set as music, the entertainment of character information transmission can be increased, and therefore user experience can be improved.
S5, decoding the sound information, identifying the sound element carrying information in the sound information, converting the sound information into N-system data through a first mapping table, converting the N-system data into binary data through a third mapping table, and converting the binary data into character information expression through a second mapping table.
The embodiment of the invention can also store or display the sound information in a character mode by a reverse processing mode, namely, the sound element is converted into N-system data by identifying the sound element, such as musical notes of music, the N-system data is converted into binary data, and finally the binary data is converted into character information to be expressed.
Second embodiment
The second embodiment of the present invention provides an information conversion method, which is substantially the same as the first embodiment except that N ^ 2^ m is used in the second embodiment, and after the operations S1-S3 are performed, S4 is performed: the binary digits converted from the text are divided into a plurality of sections by taking m digits as a section, wherein the last section may be equal to m or less than m. The binary digits contained in all but the last section are converted to N ^ 2^ m. The number in other systems which can not appear in the N system is used as the initiation codon, the content of the last subsection is placed behind the initiation codon, the number of the initiation codon is the same as the number of the last subsection, and the number in the last subsection is expressed by the N system. And converting the N-system data into sound information through a first mapping table for storage.
For example, when N ^ 2^3 ^ 8, aa corresponds to a binary 0110000101100001, which we divide by 3 digits, i.e., "011", "000", "010", "110", "000", and "1", assuming that the start codon in the 8-ary is 8, the binary can be converted to 3026081. The binary number corresponding to "a" is 01100001, which we divide by 3 digits, i.e., "011", "000", "01", and assuming that the initiation codon in 8 is 8, the binary number can be converted to 30881. This arrangement prevents binary codes such as "01" and "1" from being confused during the conversion process. This embodiment provides better space savings with a significant reduction in separators. Moreover, 1-7 in octal can directly correspond to (1-7) in the seventh scale, 0 in octal can directly correspond to rest symbol, and the start codon 8 in octal can be replaced by other high pitch or low pitch musical notes, such as high pitch do, so that the conversion from text to music (or music to text) is more convenient.
Specifically, when m is 4, since each character corresponds to an integer multiple of 8 binary characters, the number of the last bar is also 4, so that the initiation codon is not set any more, and the binary number corresponding to each bar is directly expressed by a 16-ary number. For example, aa corresponds to binary 0110000101100001, which is divided by 4 digits as a measure, i.e., "0110", "0001", and the binary can be converted into 6161. And then the music can be converted into music according to the mapping table determined in the step S1. Thus, the initiation codon is saved, and the conversion process is more concise and efficient.
