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.
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 Lea Goodrem AM (born 9 November 1984) is an Australian singer, songwriter, television personality and actress. Goodrem signed a recording contract with Sony Music at the age of 15. Her debut studio album, Innocent Eyes (2003), topped the ARIA Albums Chart for 29 non-consecutive weeks. It is one of the highest-selling Australian albums and ...
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 ...
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were David Wheeler and Roger Needham of the Cambridge Computer Laboratory, and the algorithm was presented in an unpublished technical report in 1997 (Needham and Wheeler, 1997).
AArch64. Armv8-A platform with Cortex-A57 / A53 MPCore big.LITTLE CPU chip. AArch64 or ARM64 is the 64-bit architecture of the ARM architecture family. It was first introduced with the Armv8-A architecture, and had many extension updates.
Continuously variable slope delta modulation ( CVSD or CVSDM) is a voice coding method. It is a delta modulation with variable step size (i.e., special case of adaptive delta modulation ), first proposed by Greefkes and Riemens in 1970. CVSD encodes at 1 bit per sample, so that audio sampled at 16 kHz is encoded at 16 kbit/s.
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 ...
