xdelta .org. xdelta is a command line program for delta encoding, which generates the difference between two files. This is similar to diff and patch, but it is targeted for binary files and does not generate human readable output. It was first released in 1997. [3]
Delta modulation ( DM or Δ-modulation) is an analog-to-digital and digital-to-analog signal conversion technique used for transmission of voice information where quality is not of primary importance. DM is the simplest form of differential pulse-code modulation (DPCM) where the difference between successive samples is encoded into n-bit data ...
Delta encoding is a way of storing or transmitting data in the form of differences (deltas) between sequential data rather than complete files; more generally this is known as data differencing. Delta encoding is sometimes called delta compression, particularly where archival histories of changes are required (e.g., in revision control software.
XTEA. In cryptography, XTEA ( eXtended TEA) is a block cipher designed to correct weaknesses in TEA. The cipher 's designers were David Wheeler and Roger Needham of the Cambridge Computer Laboratory, and the algorithm was presented in an unpublished technical report in 1997 (Needham and Wheeler, 1997).
Delta purchased the aircraft at a steep discount: $19.6m each, well below their $33.2m production cost, which led Boeing to accuse the company of dumping the aircraft. Delta would later increase its order to a total of 145 A220 aircraft. For its wide-body fleet, Delta acquired 25 Airbus A330neo and 42 of the newly introduced Airbus A350 ...
On redistributing updates, Windows Server Update Services has supported delta updates since Windows Server 2003. FreeBSD. FreeBSD has supported delta updates using portsnap since November 2005. Given FreeBSD's traditional stance of focusing on source code updates, no method of delta binary updates currently exists. Google
Adaptive differential pulse-code modulation ( ADPCM) is a variant of differential pulse-code modulation (DPCM) that varies the size of the quantization step, to allow further reduction of the required data bandwidth for a given signal-to-noise ratio . Typically, the adaptation to signal statistics in ADPCM consists simply of an adaptive scale ...
Delta-sigma ( ΔΣ; or sigma-delta, ΣΔ) modulation is an oversampling method for encoding signals into low bit depth digital signals at a very high sample-frequency as part of the process of delta-sigma analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). Delta-sigma modulation achieves high quality by utilizing a ...
