PMCD
PMCD (PreMaster CD) is a specially formatted, recordable Compact Disc designed to be sent to a CD pressing plant for replication. The PreMaster CD format, developed in the early 1990s by the CD-ROM division of Sony, in cooperation wit"START Lab Inc."of Tokyo and Sonic Solutions, contained a hidden "PreMaster Cue Sheet" that held the metadata needed for replication that a ''Red Book'' CD-DA lacks. The PreMaster CD format made use of the fact that not all data-recording surfaces are specified for use in the ''Red Book'' CD-DA or ''Yellow Book'' CD-ROM standards. CD transports were not able to recover the data hidden in the Cue Sheet unless commanded to by proprietary software. The Cue Sheet specified a broad range of metadata, including number of channels, per track pre-emphasis status, per track copy protection bit setting, per track ISRC Codes, per disc UPC/ EAN, etc. (see Compact Disc subcode). Despite claims to the contrary, only Sonic Solutions' "Sonic System" software was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disc Description Protocol
Disc Description Protocol (DDP) is a format for specifying the content of optical discs, including CDs and DVDs. DDP is commonly used for delivery of disc premasters for duplication. DDP is a proprietary format and is the property of DCA. The file format specification is not freely available. The DDP must contain 4 parts:Francis Rumsey, Desktop Audio Technology, 2004, Focal Press # Audio image(s) (.DAT file(s)) # DDP Identifier (DDPID) # DDP Stream descriptor (DDPMS) # Subcode descriptor (PQDESCR) An optional text file, containing the track titles and timings, can also be included.

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] |
Universal Product Code
The Universal Product Code (UPC or UPC code) is a barcode#Symbologies, barcode symbology that is used worldwide for tracking trade items in stores. The chosen symbology has bars (or spaces) of exactly 1, 2, 3, or 4 units wide each; each decimal digit to be encoded consists of two bars and two spaces chosen to have a total width of 7 units, in both an "even" and an "odd" wikt:parity#Noun, parity form, which enables being scanned in either direction. Special "guard patterns" (3 or 5 units wide, not encoding a digit) are intermixed to help decoding. A UPC (technically, a UPC-A) consists of 12 digits that are uniquely assigned to each trade item. The international GS1 organisation assigns the digits used for both the UPC and the related International Article Number (EAN) barcode. UPC data structures are a component of Global Trade Item Numbers (GTINs) and follow the global GS1 specification, which is based on international standards. Some retailers, such as clothing and furniture, d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Audio Data
Digital audio is a representation of sound recorded in, or converted into, digital form. In digital audio, the sound wave In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the ''reception'' of such waves and their ''perception'' by the ... of the audio signal is typically encoded as numerical sampling (signal processing), samples in a continuous sequence. For example, in CD audio, samples are taken 44,100 Hertz, times per second, each with 16-bit audio bit depth, resolution. Digital audio is also the name for the entire technology of sound recording and reproduction using audio signals that have been encoded in digital form. Following significant advances in digital audio technology during the 1970s and 1980s, it gradually replaced comparison of analog and digital recording, analog audio technology in many areas of audio engineering, record pr ...
