Abstract: A method of encoding data includes determining a magnitude of change between a first value associated with first data and a second value associated with second data based on a comparison of the first value and the second value. The first value is encoded into a first set of bits having a first number of bits. The method includes determining, based on the comparison of the first value and the second value, a second number of bits (that is less than the first number of bits) to be used to encode the magnitude of change. The method includes encoding the magnitude of change into a second set of bits having the second number of bits. The method further includes sending the second set of bits and a first indicator, with the first indicator indicating that the magnitude of change is encoded into the second number of bits.

Abstract: A pair of adjacent characters in a plain ASCII data stream is examined for a condition that the pair contains a consonant followed by one of a set of characters, or a vowel followed by one of the set of characters. The set of characters is selected only from vowels and the space character. If the condition is satisfied, the pair is encoded as a corresponding extended ASCII code. If the condition is not satisfied, the first character of the pair is emitted as a corresponding plain ASCII code, and a next pair is formed with the second character of the (previous) pair as the first character and a next character of the plain ASCII stream as the second character. The next pair as well as further pairs are examined for the condition and correspondingly processed. Compression of the plain ASCII data stream is thereby achieved.

Abstract: A sorting decoder captures the rank-order of a set of input analogue signals in the digital domain using simple logic components such as self-timed first state elements, without requiring conventional analogue-to-digital signal converters. The analogue signals are each compared against a monotonic dynamic reference and the resulting comparisons are snapshot by a self-timed first state element for each input signal, or the last member of a sorted collection of input signals, at the time when it reaches the reference signal, so that a different snapshot representing the signal value ranking relative to the other signal values is produced for each input signal. The resulting rank-order estimation snapshots are binary signals that can then be further processed by a simple sorting logic circuit based on elementary logic components.

Abstract: Disclosed are a context-based arithmetic encoding apparatus and method and a context-based arithmetic decoding apparatus and method. The context-based arithmetic decoding apparatus may determine a context of a current N-tuple to be decoded, determine a Most Significant Bit (MSB) context corresponding to an MSB symbol of the current N-tuple, and determine a probability model using the context of the N-tuple and the MSB context. Subsequently, the context-based arithmetic decoding apparatus may perform a decoding on an MSB based on the determined probability model, and perform a decoding on a Least Significant Bit (LSB) based on a bit depth of the LSB derived from a process of decoding on an escape code.
