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] |
Palette (computing)
In computer graphics, a palette is the set of available colors from which an image can be made. In some systems, the palette is fixed by the hardware design, and in others it is dynamic, typically implemented via a color lookup table (CLUT), a correspondence table in which selected colors from a certain color space's color reproduction range are assigned an index, by which they can be referenced. By referencing the colors via an index, which takes less information than needed to describe the actual colors in the color space, this technique aims to reduce data usage, including processing, transfer bandwidth, RAM usage, and storage. Images in which colors are indicated by references to a CLUT are called indexed color images. Description As of 2019, the most common image colorspace in graphics cards is the RGB color model with 8 bits per pixel color depth. Using this technique, 8 bits per pixel are used to describe the luminance level in each of the RGB channels, therefore 24 b ...

Sega Saturn
The is a home video game console developed by Sega and released on November 22, 1994, in Japan, May 11, 1995, in North America, and July 8, 1995, in Europe. Part of the fifth generation of video game consoles, it was the successor to the successful Sega Genesis. The Saturn has a dual- CPU architecture and eight processors. Its games are in CD-ROM format, and its game library contains several ports of arcade games as well as original games. Development of the Saturn began in 1992, the same year Sega's groundbreaking 3D Model 1 arcade hardware debuted. The Saturn was designed around a new CPU from the Japanese electronics company Hitachi. Sega added another video display processor in early 1994 to better compete with Sony's forthcoming PlayStation. The Saturn was initially successful in Japan but failed to sell in large numbers in the United States, where it was hindered by a surprise May 1995 launch, four months before its scheduled release date. After the debut of the Ninte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sega CD
The Sega CD, released as the in most regions outside North America and Brazil, is a CD-ROM accessory for the Sega Genesis produced by Sega as part of the fourth generation of video game consoles. It was released on December 12, 1991, in Japan, October 15, 1992, in North America, and April 2, 1993, in Europe. The Sega CD plays CD games and adds hardware functionality such as a faster CPU and graphic enhancements such as sprite scaling and rotation. It can also play audio CDs and CD+G discs. Sega sought to match the capabilities of the competing PC Engine CD-ROM² System, and added an additional CPU and custom graphics chip. They partnered with JVC to design the Sega CD. Fearful of leaks, Sega refused to consult with Sega of America until the project was complete; Sega of America assembled parts from dummy units to obtain a functioning unit. The Sega CD was redesigned several times by Sega and licensed third-party developers. The main benefit of CD technology at the time w ...

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 ...

PC-FX
The is a 32-bit home video game console developed by NEC and Hudson Soft. It was released in 1994 and discontinued in February 1998, as NEC's final home video game console. Based on the NEC V810 CPU and CD-ROM, it was intended as the successor to the PC Engine (known oherseas as the TurboGrafx-16). Unlike its predecessor, the PC-FX was only released in Japan. Its form factor is like that of a tower PC, intended to be similarly upgradeable. The PC-FX was uncompetitive with its fifth generation peers due to lack of a 3D polygon-based graphics chip, high price, and limited developer support and is considered a commercial failure. History In 1987, NEC partnered with game publisher Hudson Soft to create the PC Engine, released internationally as the TurboGrafx-16. The PC Engine was successful in Japan, but the TG-16 struggled in overseas markets. The success of the PC Engine created a strong relationship between NEC and Hudson, who began work on a true successor (as opposed to t ...

Turbo Duo
The TurboDuo is a fourth-generation video game console developed by NEC Home Electronics and Hudson Soft for the North American market. The TurboDuo was test-marketed in Los Angeles in October 1992, before a nationwide rollout in May 1993. It is the North American version of the Japanese PC Engine Duo game console which was released in September 1991. In the United States, the TurboDuo was marketed by Turbo Technologies, Inc. (or TTI) of Los Angeles, a joint venture of NEC Home Electronics and Hudson Soft. It was established to market NEC consoles in North America after NEC Home Electronics USA failed to effectively market the platform. The TurboDuo integrates the capabilities of the TurboGrafx-16 and its CD-ROM drive (the TurboGrafx-CD) into a single, redesigned unit with an updated BIOS and 192 KB of additional RAM. TTI also offered the Super System Card via mail order, which provided the original TurboGrafx-CD with the 192 KB RAM upgrade. The RAM increase and BIOS update aff ...

Compact Disc
The compact disc (CD) is a Digital media, digital optical disc data storage format that was co-developed by Philips and Sony to store and play digital audio recordings. In August 1982, the first compact disc was manufactured. It was then released in October 1982 in Japan and branded as ''Compact Disc Digital Audio, Digital Audio Compact Disc''. The format was later adapted (as CD-ROM) for general-purpose data storage. Several other formats were further derived, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video CD (VCD), Super Video CD (SVCD), Photo CD, Picture CD, Compact Disc-Interactive (CD-i) and Enhanced Music CD. Standard CDs have a diameter of and are designed to hold up to 74 minutes of uncompressed stereo digital audio or about 650 mebibyte, MiB of data. Capacity is routinely extended to 80 minutes and 700 mebibyte, MiB by arranging data more closely on the same sized disc. The Mini CD has various diameters ranging from ; t ...
