Base32 is an encoding method based on the base-32 numeral system.It uses an alphabet of 32 digits, each of which represents a different combination of 5 bits (2 5).Since base32 is not very widely adopted, the question of notation—which characters to use to represent the 32 digits—is not as settled as in the case of more well-known numeral systems (such as hexadecimal), though RFCs and ...
Huffman tree generated from the exact frequencies of the text "this is an example of a huffman tree". Encoding the sentence with this code requires 135 (or 147) bits, as opposed to 288 (or 180) bits if 36 characters of 8 (or 5) bits were used (This assumes that the code tree structure is known to the decoder and thus does not need to be counted as part of the transmitted information).
Character encoding is the process of assigning numbers to graphical characters, especially the written characters of human language, allowing them to be stored, transmitted, and transformed using digital computers. [ 1] The numerical values that make up a character encoding are known as "code points" and collectively comprise a "code space", a ...
The sequence \uhhhh denotes the code point hhhh, interpreted as a hexadecimal number. The sequence \U hhhhhhhh denotes the code point hhhhhhhh , interpreted as a hexadecimal number. Code points located at U+10000 or higher must be denoted with the \U syntax, whereas lower code points may use \u or \U .
A six-bit character code is a character encoding designed for use on computers with word lengths a multiple of 6. Six bits can only encode 64 distinct characters, so these codes generally include only the upper-case letters, the numerals, some punctuation characters, and sometimes control characters. The 7-track magnetic tape format was ...
Range coding. Range coding (or range encoding) is an entropy coding method defined by G. Nigel N. Martin in a 1979 paper, [ 1] which effectively rediscovered the FIFO arithmetic code first introduced by Richard Clark Pasco in 1976. [ 2] Given a stream of symbols and their probabilities, a range coder produces a space-efficient stream of bits to ...
For example, "BAT" becomes "12 11 44". The 26 letters of the Latin/English alphabet do not fit in a 5 × 5 square, two letters must be combined (usually I and J as above, though C and K is an alternative). Alternatively, a 6 × 6 grid may be used to allow numerals or special characters to be included as well as letters.
Some ASN.1 compilers can produce code to encode or decode several encodings, e.g. packed, BER or XML. ASN.1 is a joint standard of the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) in ITU-T Study Group 17 and International Organization for Standardization / International Electrotechnical Commission (ISO ...
