Colors Of Noise
In audio engineering, electronics, physics, and many other fields, the color of noise or noise spectrum refers to the power spectrum of a noise signal (a signal produced by a stochastic process). Different colors of noise have significantly different properties. For example, as audio signals they will sound different to human ears, and as images they will have a visibly different texture. Therefore, each application typically requires noise of a specific color. This sense of 'color' for noise signals is similar to the concept of timbre in music (which is also called "tone color"; however, the latter is almost always used for sound, and may consider detailed features of the spectrum). The practice of naming kinds of noise after colors started with white noise, a signal whose spectrum has equal power within any equal interval of frequencies. That name was given by analogy with white light, which was (incorrectly) assumed to have such a flat power spectrum over the visible ...

JPEG
JPEG ( , short for Joint Photographic Experts Group and sometimes retroactively referred to as JPEG 1) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable trade off between storage size and image quality. JPEG typically achieves 10:1 compression with noticeable, but widely agreed to be acceptable perceptible loss in image quality. Since its introduction in 1992, JPEG has been the most widely used image compression standard in the world, and the most widely used digital image format, with several billion JPEG images produced every day as of 2015. The Joint Photographic Experts Group created the standard in 1992, based on the discrete cosine transform (DCT) algorithm. JPEG was largely responsible for the proliferation of digital images and digital photos across the Internet and later social media. JPEG compression is used in a number of ...

C-Cube
C-Cube Microsystems, Inc., was an early company in video compression technology as well as the implementation of that technology into semiconductor integrated circuits and systems. C-Cube was the first company to deliver on the market opportunity presented by the conversion of image and video data from analog to digital formats enabling markets such as VideoCD, DVD, DirecTV, digital cable, and non-linear editing systems. History C-Cube was founded on August 8, 1988 by Edmund Sun from Weitek and Alexandre Balkanski. Early funding came from VC firms Hambrecht & Quist and JAFCO America Ventures as well as Japanese farm equipment manufacturer Kubota Ltd. Image and video technology was just beginning to make the transition from analog (VHS, Betamax, etc.) to new digital-base formats. The key issue was the amount of bandwidth required to transmit or store the digital content. Digital video compression was a key enabling technology that made digital video practical.

Pentium
Pentium is a series of x86 architecture-compatible microprocessors produced by Intel from 1993 to 2023. The Pentium (original), original Pentium was Intel's fifth generation processor, succeeding the i486; Pentium was Intel's flagship processor line for over a decade until the introduction of the Intel Core line in 2006. Pentium-branded processors released from 2009 onwards were considered entry-level products positioned above the low-end Intel Atom, Atom and Celeron series, but below the faster Core lineup and workstation/server Xeon series. The later Pentiums, which have little more than their name in common with earlier Pentiums, were based on both the architecture used in Atom and that of Core processors. In the case of Atom architectures, Pentiums were the highest performance implementations of the architecture. Pentium processors with Core architectures prior to 2017 were distinguished from the faster, higher-end i-series processors by lower clock rates and disabling ...

DEC Alpha
Alpha (original name Alpha AXP) is a 64-bit reduced instruction set computer (RISC) instruction set architecture (ISA) developed by Digital Equipment Corporation (DEC). Alpha was designed to replace 32-bit VAX complex instruction set computers (CISC) and to be a highly competitive RISC processor for Unix workstations and similar markets. Alpha was implemented in a series of microprocessors originally developed and fabricated by DEC. These microprocessors were most prominently used in a variety of DEC workstations and servers, which eventually formed the basis for almost all of their mid-to-upper-scale lineup. Several third-party vendors also produced Alpha systems, including PC form factor motherboards. Operating systems that support Alpha included OpenVMS (formerly named OpenVMS AXP), Tru64 UNIX (formerly named DEC OSF/1 AXP and Digital UNIX), Windows NT (discontinued after NT 4.0; and prerelease Windows 2000 RC2), Linux (Debian, SUSE, Gentoo and Red Hat), BSD UNIX (NetBS ...

Multimedia
Multimedia is a form of communication that uses a combination of different content forms, such as Text (literary theory), writing, Sound, audio, images, animations, or video, into a single presentation. This is in contrast to traditional mass media, such as printed material or audio recordings, which only feature one form of media content. Popular examples of multimedia include video podcasts, audio slideshows, and animated videos. Creating multimedia content involves the application of the principles of effective interactive communication. The five main building blocks of multimedia are text, image, audio, video, and animation. Multimedia encompasses various types of content, each serving different purposes: * Text - Fundamental to multimedia, providing context and information. * Audio - Includes music, sound effects, and voiceovers that enhance the experience. Recent developments include spatial audio and advanced sound design. * Ima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TURBOchannel
TURBOchannel is an open computer bus developed by DEC by during the late 1980s and early 1990s. Although it is open for any vendor to implement in their own systems, it was mostly used in Digital's own systems such as the MIPS-based DECstation and DECsystem systems, in the VAXstation 4000, and in the Alpha-based DEC 3000 AXP. Digital abandoned the use of TURBOchannel in favor of the EISA and PCI buses in late 1994, with the introduction of their AlphaStation and AlphaServer systems. History TURBOchannel was developed in the late 1980s by Digital and was continuously revised through the early 1990s by the TURBOchannel Industry Group, an industry group set up by Digital to develop promote the bus. TURBOchannel has been an open bus from the beginning, the specification was publicly available at an initial purchase cost for the reproduction of material for third-party implementation, as were the mechanical specifications, for both implementation in both systems and in opti ...

Ultrix
Ultrix (officially all-caps ULTRIX) is the brand name of Digital Equipment Corporation's (DEC) discontinued native Unix operating systems for the PDP-11, VAX, MicroVAX and DECstations. History The initial development of Unix occurred on DEC equipment, notably DEC PDP-7 and PDP-11 (Programmable Data Processor) systems. Later DEC computers, such as their VAX, also offered Unix. The first port to VAX, UNIX/32V, was finished in 1978, not long after the October 1977 announcement of the VAX, for which – at that time – DEC only supplied its own proprietary operating system, VMS. DEC's Unix Engineering Group (UEG) was started by Bill Munson with Jerry Brenner and Fred Canter, both from DEC's Customer Service Engineering group, Bill Shannon (from Case Western Reserve University), and Armando Stettner (from Bell Labs). Other later members of UEG included Joel Magid, Bill Doll, and Jim Barclay recruited from DEC's marketing and product management groups. Under Canter's directio ...
