Red Book (CD Standard)
The Rainbow Books are a collection of CD format specifications. ''Red Book'' (1980) *CD-DA (''Digital Audio'') – standardized as IEC 60908 **CD-Text—a 1996 extension to CD-DA ** CD-MIDI—part of the original red-book standard **CD+G (''plus Graphics'') – karaoke *** CD+EG / CD+XG (''plus Extended Graphics'') – an extension of CD+G ''Yellow Book'' (1983) *CD-ROM (''Read-Only Memory'') – standardized as ISO/IEC 10149 in 1988 and ECMA-130 in 1989 **CD-ROM XA (''eXtended Architecture'') – a 1991 extension of CD-ROM ''Green Book'' (1986) *CD-i (''Interactive'') ''Orange Book'' (1990) Orange is a reference to the fact that red and yellow mix to orange. This correlates with the fact that CD-R and CD-RW are capable of audio ("Red") and data ("Yellow"); although other colors (other CD standards) that do not mix are capable of being burned onto the physical medium. ''Orange Book'' also introduced the standard for multisession writing. *CD-MO (''Magneto-Optical'') ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Security
Computer security, cybersecurity (cyber security), or information technology security (IT security) is the protection of computer systems and networks from attack by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide. The field has become of significance due to the expanded reliance on computer systems, the Internet, and wireless network standards such as Bluetooth and Wi-Fi, and due to the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity is one of the most significant challenges of the contemporary world, due to both the complexity of information systems and the societies they support. Security is of especially high importance for systems that govern large-scale systems with far-reaching physical effects, such as power distribution, ...

Photo CD
Photo CD is a system designed by Kodak for digitizing and saving photos onto a CD. Launched in 1991, the discs were designed to hold nearly 100 high quality images, scanned prints and slides using special proprietary encoding. Photo CDs are defined in the Beige Book and conform to the CD-ROM XA and CD-i Bridge specifications as well. They were intended to play on CD-i players, Photo CD players ( Apple's PowerCD for example), and any computer with a suitable software ( LaserSoft Imaging's SilverFast DC or HDR for example). The system failed to gain mass usage among consumers partly due to its proprietary nature, the rapidly decreasing scanner prices, and the lack of CD-ROM drives in most home personal computers of the day. Furthermore, Photo CD relied on CRT-based TV sets for home use. However, these were designed for moving pictures. Their typical flicker became an issue when watching still photographs. The Photo CD system gained a fair level of acceptance among professional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ThinkQuest
ThinkQuest was an educational website, created 1996 and intended for primary and secondary schools. Beginning 2002 it was owned by the Oracle Education Foundation and was known as Oracle ThinkQuest. History ThinkQuest was created in 1996 by Allan H. Weis as part of his nonprofit Advanced Network and Services. The website and competition were acquired by the Oracle Education Foundation in 2002. Prior to being acquired by the Oracle Education Foundation, April Wennerstrom (née Buther) led the international training and evaluation program for the competition and worked with a cadre of international educators and judges to identify scholarship recipients. During its time under ANS' leadership, the organization gave over $1.5 million dollars annually for scholarships and support for the student-created sites and program participants spanned over 75 countries and six continents. As of July 1, 2013, the ThinkQuest initiative was discontinued.http://www.thinkquest.org/en/ -- or, the arc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orange-Book-Standard
''Orange-Book-Standard'' (Az. KZR 39/06) is a decision issued on May 6, 2009 by the Federal Court of Justice of Germany (german: Bundesgerichtshof, BGH) on the interaction between patent law and technical standards, and more generally between intellectual property law and competition law. The Court held that a defendant, accused of patent infringement and who was not able to obtain a license from the patentee, may defend himself, under certain conditions, by invoking an abuse of a dominant market position. The name "Orange-Book-Standard" comes from the Orange Book that contained the format specifications for CD-Rs, the technology at issue in the case that led to the Orange-Book-Standard decision.Mark Schweizer"Dutch see Orange Book differently; Philips prevails again" IPKat, March 18, 2010.

ISO 9660
ISO 9660 (also known as ECMA-119) is a file system for optical disc media. Being sold by the International Organization for Standardization (ISO) the file system is considered an international technical standard. Since the specification is available for anybody to purchase, implementations have been written for many operating systems. ISO 9660 traces its roots to the ''High Sierra Format'', which arranged file information in a dense, sequential layout to minimize nonsequential access by using a hierarchical (eight levels of directories deep) tree file system arrangement, similar to UNIX and FAT. To facilitate cross platform compatibility, it defined a minimal set of common file attributes (directory or ordinary file and time of recording) and name attributes (name, extension, and version), and used a separate system use area where future optional extensions for each file may be specified. High Sierra was adopted in December 1986 (with changes) as an international standard by E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double-density Compact Disc
The double-density compact disc (DDCD) is an optical disc technology developed by Sony using the same laser wavelength as a compact disc, namely 780 nm. The format is defined by the ''Purple Book'' standard document. Unlike the compact-disc technology it is based on, DDCD was designed exclusively for data with no audio capabilities. For a 12 cm disc, it doubles the original 650 MB to 1.3 GB capacity of a CD on recordable (DDCD-R) and rewritable (DDCD-RW) discs by narrowing the track pitch from 1.6 to 1.1 micrometers, and shortening the minimum pit length from 0.833 to 0.623 micrometers. The DDCD was also available in read-only format (DDCD-ROM). The specification allowed for both 12 cm and 8 cm discs, although it appears no 8 cm media was ever released. The technology, released years after rewritable DVD technology, failed to acquire significant market share. The only DDCD recorder introduced was the Sony CRX200E. While the initial launch price of the drive and the disc ($249 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Super Audio CD
Super Audio CD (SACD) is an optical disc format for audio storage introduced in 1999. It was developed jointly by Sony and Philips Electronics and intended to be the successor to the Compact Disc (CD) format. The SACD format allows multiple audio channels (i.e. surround sound or multichannel sound). It also provides a higher bit rate and longer playing time than a conventional CD. An SACD is designed to be played on an SACD player. A ''hybrid SACD'' contains a Compact Disc Digital Audio (CDDA) layer and can also be played on a standard CD player. History The Super Audio CD format was introduced in 1999, and is defined by the ''Scarlet Book'' standard document. Philips and Crest Digital partnered in May 2002 to develop and install the first SACD hybrid disc production line in the United States, with a production capacity of up to three million discs per year. SACD did not achieve the level of growth that compact discs enjoyed in the 1980s, and was not accepted by the mainstr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Book (CD Standard)
The Blue Book is a compact disc standard developed in 1995 by Philips and Sony. It defines the Enhanced Music CD format (E-CD, also known as CD-Extra, CD-Plus and CD+), which combines audio tracks and data tracks on the same disc. The format was created as a way to solve the problem of mixed mode CDs, which were not properly supported by many CD players. E-CDs are created through the ''stamped multisession'' technology, which creates two sessions on a disc. The first session of an E-CD contains audio tracks according to the Red Book. As a consequence, existing compact disc players can play back this first session as an audio disc. The second session contains CD-ROM data files with content often related to the audio tracks in the first session. The second session will only be used by computer systems equipped with a CD-ROM drive, or by special “Enhanced CD players”. The second session of a E-CD contains one track in CD-ROM XA Mode 2, Form 1 format. It must contain certain s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Super Video CD
Super Video CD (Super Video Compact Disc or SVCD) is a digital format for storing video on standard compact discs. SVCD was intended as a successor to Video CD and an alternative to DVD-Video, and falls somewhere between both in terms of technical capability and picture quality. Technical specifications Structure Similar to VCDs, SVCDs comply with the CD-i Bridge format, and are authored (or "burned") using the CD-ROM XA format. The first track is in CD-ROM XA Mode 2, Form 1, and contains metadata about the disc. The other tracks are in Mode 2, Form 2, and contain audio and video multiplexed in a MPEG program stream (MPEG-PS) container. This allows roughly 800 megabytes of data to be stored on one 80 minute CD (versus 700 megabytes when using Mode 1). One CD can hold up to 35 minutes of full quality SVCD-format video and audio. Video * Compression: MPEG-2 * Resolution: 2/3 D1 ** analog NTSC compatible: 480x480 (480i) ** analog PAL/SECAM compatible: 480x576 (576i) * Aspe ...

Video CD
Video CD (abbreviated as VCD, and also known as Compact Disc Digital Video) is a home video format and the first format for distributing films on standard optical discs. The format was widely adopted in Southeast Asia, Central Asia and the Middle East, superseding the VHS and Betamax systems in the regions until DVD-Video finally became affordable in the first decade of the 21st century. The format is a standard digital data format for storing video on a compact disc. VCDs are playable in dedicated VCD players and widely playable in most DVD players, personal computers and some video game consoles. However, they are less playable in most Blu-ray Disc players, vehicle audio with DVD/Blu-ray support and video game consoles such as the Sony PlayStation and Xbox due to lack of backward compatibility for the older MPEG-1 format, inability to read MPEG-1 in .dat files alongside MPEG-1 in standard MPEG-1, AVI, and Matroska files, or inability to read CD-ROM XA discs.

Green Book (CD Standard)
The Compact Disc-Interactive (CD-I, later CD-i) is a Digital media, digital optical disc data storage device, data storage format that was mostly developed and marketed by Dutch company Philips. It was created as an extension of Compact Disc Digital Audio, CDDA and CD-ROM and specified in the ''Rainbow Books, Green Book'', co-developed by Philips and Sony, to combine audio, text and graphics. The two companies initially expected to impact the education/training, point of sale, and home entertainment industries, but CD-i eventually became best known for its video games. CD-i media physically have the same dimensions as CD, but with up to of digital data storage, including up to 72 minutes of full motion video. CD-i players were usually standalone boxes that connect to a standard television; some less common setups included integrated CD-i television sets and expansion modules for personal computers. Most players were created by Philips; the format was licensed by Philips and Mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
