CD-i Ready
CD-i Ready is a compact disc format for mixing audio and data content on a CD. It was developed by Phillips in 1991, based on the CD-i format. The CD-i Ready format uses a certain technique to get audio CD players to skim over the CD-i software and data. CD-i Ready places software and data in the pregap of track 1 (index 0). ''Philips Interactive Media Systems'' - October 1991 Technical specification of the 'CD-i Ready' type disc. CD-i Ready is an Audio-CD with CD-i data located in the pre-gap before track 1.

Compact Disc
The compact disc (CD) is a Digital media, digital optical disc data storage format co-developed by Philips and Sony to store and play digital audio recordings. It employs the Compact Disc Digital Audio (CD-DA) standard and was capable of holding of uncompressed stereo audio. First released in Japan in October 1982, the CD was the second optical disc format to reach the market, following the larger LaserDisc (LD). In later years, the technology was adapted for computer data storage as CD-ROM and subsequently expanded into various writable and multimedia formats. , over 200 billion CDs (including audio CDs, CD-ROMs, and CD-Rs) had been sold worldwide. Standard CDs have a diameter of and typically hold up to 74 minutes of audio or approximately of data. This was later regularly extended to 80 minutes or by reducing the spacing between data tracks, with some discs unofficially reaching up to 99 minutes or which falls outside established specifications. Smaller variants, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philips CD-i
The Compact Disc-Interactive (CD-I, later CD-i) is a digital optical disc data storage format as well as a hardware platform, co-developed and marketed by Dutch company Philips and Japanese company Sony. It was created as an extension of CDDA and CD-ROM and specified in the '' Green Book'' specifications, 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 the CD-i is largely remembered today 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 us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Book (audio CD Standard)
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'' technical specifications, which is why the format is also dubbed ''"Redbook audio"'' in some contexts. CDDA utilizes pulse-code modulation (PCM) and uses a 44,100 Hz sampling frequency and 16-bit resolution, and was originally specified to store up to 74 minutes of stereo audio per disc. The first commercially available audio CD player, the Sony CDP-101, was released in October 1982 in Japan. The format gained worldwide acceptance in 1983–84, selling more than a million CD players in its first two years, to play 22.5 million discs, before overtaking records and cassette tapes to become the dominant standard for commercial music. Peaking around year 2000, the audio CD contracted over the next decade due to rising popularity and revenue from digital downloading, and duri ...

Pregap
The pregap on a Red Book audio CD is the portion of the audio track that precedes "index 01" for a given track in the table of contents (TOC). The pregap ("index 00") is typically two seconds long and usually, but not always, contains silence. Popular uses for having the pregap contain audio are live CDs, track interludes, and hidden songs in the pregap of the first track (detailed below). Unconventional uses of the pregap Computer data in pregap The track 01 pregap was used to hide computer data, allowing computers to detect a data track whereas conventional CD players would continue to see the CD as an audio CD. This method was made obsolete in mid 1996 when an update to Windows 95 in driver SCSI1HLP.VXD made the pregap track inaccessible. It is unclear whether this change in Microsoft Windows' behavior was intentional: for instance, it may have been intended to steer developers away from the pregap method and encourage what became the Blue Book specification "CD Extra" for ...

CD Player
A CD player is an electronic device that plays audio compact discs, which are a digital audio, 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 power amplifier, 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, Advanced Audio Coding, AAC and Windows Media Audio, WMA. DJs playing dance music at clubs often use specialize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enhanced CD
Enhanced CD is a certification mark of the Recording Industry Association of America for various technologies that combine audio and computer data for use in both CD-Audio and CD-ROM players. Formats that fall under the ''enhanced CD'' category include mixed mode CD (Yellow Book CD-ROM/Red Book CD-DA), CD-i, CD-i Ready, and CD-Extra/CD-Plus ( Blue Book, also called simply Enhanced Music CD or E-CD).

Mixed Mode CD
A mixed mode CD is a compact disc which contains both data and audio in one session. Typically the first track is a data track while the rest are audio tracks. The most common use for mixed mode CDs is to add CD-quality audio to video games on a CD. The term "enhanced CD" is sometimes used to refer to mixed mode CDs, though it is most commonly used to refer to either a more general category of formats that mix audio and data tracks, or to the particular Enhanced Music CD format. Overview Mixed mode CDs are implicitly described in the original CD-ROM standard (the ''Yellow Book'', later standardized as ISO/IEC 10149 and ECMA-130), which allows a CD-ROM to contain only data tracks, or data tracks and audio tracks. The CD-ROM standard, however, does not mention the term "mixed mode", nor does it describe any particular order of data and audio tracks on the disc. Since the original CD-ROM standard did not support multiple sessions, mixed mode CDs are created using only one sessio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enhanced Music CD
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 CD-DA, audio tracks and CD-ROM, data tracks on the same disc. The format was created as a way to solve the problem of Mixed Mode CD, mixed mode CDs, which were not properly supported by many CD players. E-CDs are created through the ''stamped multisession'' technology, which creates two Session (CD), sessions on a disc. The first session of an E-CD contains audio tracks according to the Red Book (audio CD standard), 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 o ...
