Philips CD-I
The Compact Disc-Interactive (CD-I, later CD-i) is a digital optical disc data storage format that was mostly developed and marketed by Dutch company Philips. It was created as an extension of CDDA and CD-ROM and specified in the '' 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 Microware for use by other manufacturers, notably Sony who released profes ...

Discman
Discman was Sony's brand name for portable CD players. The first Discman, the Sony D-50 or D-5 (depending on region), was launched in 1984. The brand name changed to CD Walkman, initially for Japanese lineups launched between October 1997 and March 1998, and then entirely in 2000. Discman and CD Walkman players are no longer produced. Background Prior to the development of the Compact Disc, cassette tapes were the dominant form of audio storage in the then-fledgling portable audio industry. In 1979 Sony introduced the Walkman in Japan. When Sony realized the potential of the CD, the Walkman was promoted to mainstream buyers. Original development Sony improved the design of the CDP-101 CD player which was launched in 1982, reducing the power consumption and the number of parts needed and making it smaller. The cost was reduced to between 50,000 and 60,000 yen, in what was called the "CD CD Project", which stood for 'Compact Disc Cost Down' Project. By August 1983 the comp ...

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] |
CD+G
CD+G (also known as CD-G, CD+Graphics and TV-Graphics) is an extension of the compact disc standard that can present low-resolution graphics alongside the audio data on the disc when played on a compatible device. CD+G discs are often used for karaoke machines, which use this functionality to present on-screen lyrics for the song contained on the disc. The CD+G specifications were published by Philips and Sony as an extension of the Red Book (CD standard) specifications. The first CD to be released with CD+G graphics was '' Eat or Be Eaten'' by Firesign Theatre in 1985. The CD+EG is a similar format that allows for better graphics, but has very rarely been implemented in releases. Design The CD+G format takes advantage of the six Compact Disc subcode channels R through W (which are unused in standard Compact Disc Digital Audio), to provide 6 extra bits in CD+G for graphics information per 24 bytes of audio data. When a disc is read at normal speed, these six channels provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Audio CD
Compact Disc Digital Audio (CDDA or CD-DA), also known as Digital Audio Compact Disc or simply as Audio CD, is the standard format for audio compact discs. The standard is defined in the ''Red Book'', one of a series of Rainbow Books (named for their binding colors) that contain the technical specifications for all CD formats. The first commercially available audio CD player, the Sony CDP-101, was released October 1982 in Japan. The format gained worldwide acceptance in 1983–84, selling more than a million CD players in those two years, to play 22.5 million discs. Beginning in the 2000s, CDs were increasingly being replaced by other forms of digital storage and distribution, with the result that by 2010 the number of audio CDs being sold in the U.S. had dropped about 50% from their peak; however, they remained one of the primary distribution methods for the music industry. In the 2010s, revenues from digital music services, such as iTunes, Spotify, and YouTube, match ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Authoring System
An authoring system is a program that has pre-programmed elements for the development of interactive multimedia software titles. Authoring systems can be defined as software that allows its user to create multimedia applications for manipulating multimedia objects. In the development of educational software, an authoring system is a program that allows a non-programmer, usually an instructional designer or technologist, to easily create software with programming features. The programming features are built in but hidden behind buttons and other tools, so the author does not need to know how to program. Generally authoring systems provide many graphics, much interaction, and other tools educational software needs. The three main components of an authoring system are: content organization, control of content delivery, and type(s) of assessment. Content Organization allows the user to structure and sequence the instructional content and media. Control of content delivery refers to the ...

Game Console
A video game console is an electronic device that outputs a video signal or image to display a video game that can be played with a game controller. These may be home consoles, which are generally placed in a permanent location connected to a television or other display devices and controlled with a separate game controller, or handheld consoles, which include their own display unit and controller functions built into the unit and which can be played anywhere. Hybrid consoles combine elements of both home and handheld consoles. Video game consoles are a specialized form of a home computer geared towards video game playing, designed with affordability and accessibility to the general public in mind, but lacking in raw computing power and customization. Simplicity is achieved in part through the use of game cartridges or other simplified methods of distribution, easing the effort of launching a game. However, this leads to ubiquitous proprietary formats that creates competition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CD Player
A CD player is an electronic device that plays audio compact discs, which are a digital optical disc data storage format. CD players were first sold to consumers in 1982. CDs typically contain recordings of audio material such as music or audiobooks. CD players may be part of home stereo systems, car audio systems, personal computers, or portable CD players such as CD boomboxes. Most CD players produce an output signal via a headphone jack or RCA jacks. To use a CD player in a home stereo system, the user connects an RCA cable from the RCA jacks to a hi-fi (or other amplifier) and loudspeakers for listening to music. To listen to music using a CD player with a headphone output jack, the user plugs headphones or earphones into the headphone jack. Modern units can play audio formats other than the original CD PCM audio coding, such as MP3, AAC and WMA. DJs playing dance music at clubs often use specialized players with an adjustable playback speed to alter the pitch and t ...

Newspapers
A newspaper is a periodical publication containing written information about current events and is often typed in black ink with a white or gray background. Newspapers can cover a wide variety of fields such as politics, business, sports and art, and often include materials such as opinion columns, weather forecasts, reviews of local services, obituaries, birth notices, crosswords, editorial cartoons, comic strips, and advice columns. Most newspapers are businesses, and they pay their expenses with a mixture of subscription revenue, newsstand sales, and advertising revenue. The journalism organizations that publish newspapers are themselves often metonymically called newspapers. Newspapers have traditionally been published in print (usually on cheap, low-grade paper called newsprint). However, today most newspapers are also published on websites as online newspapers, and some have even abandoned their print versions entirely. Newspapers developed in the 17th ...

Online Console Gaming
Online console gaming involves connecting a console to a network over the Internet for services. Through this connection, it provides users the ability to play games with other users online, in addition to other online services. The three most common networks now are Microsoft's Xbox network, Sony's PlayStation Network, and Nintendo's Nintendo Switch Online and Nintendo Network. These networks feature cross platform capabilities which allows users to use a single account. However, the services provided by both are still limited to the console connected (e.g. an Xbox One cannot download an Xbox 360 game, unless the game is part of the Xbox 360 to Xbox One backwards compatibility program). Additional services provided by these networks include the capability of buying additional games, online chatting, downloadable content, and game demos. Early attempts The earliest experiments relating to online connectivity on game consoles were done as far back as the early 1980s. For some con ...

Internet
The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a '' network of networks'' that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1970s to enable resource shari ...

Edutainment
Educational entertainment (also referred to as edutainment) is media designed to educate through entertainment. The term was used as early as 1954 by Walt Disney. Most often it includes content intended to teach but has incidental entertainment value. It has been used by academia, corporations, governments, and other entities in various countries to disseminate information in classrooms and/or via television, radio, and other media to influence viewers' opinions and behaviors. History Concept Interest in combining education with entertainment, especially in order to make learning more enjoyable, has existed for hundreds of years, with the Renaissance and Enlightenment being movements in which this combination was presented to students.. Komenský in particular is affiliated with the "school as play" concept, which proposes pedagogy with dramatic or delightful elements. ''Poor Richard's Almanack'' demonstrates early implementation of edutainment, with Benjamin Franklin co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
