ID3 Tag
ID3 is a metadata container most often used in conjunction with the MP3 audio file format. It allows information such as the title, artist, album, track number, and other information about the file to be stored in the file itself. ID3 is a ''de facto'' standard for metadata in MP3 files; no standardization body was involved in its creation nor has such an organization given it a formal approval status. It competes with the APE tag in this area. There are two unrelated versions of ID3: ID3v1 and ID3v2. In ID3v1, the metadata is stored in a 128-byte segment at the end of the file. In ID3v2, an extensible set of "frames" located at the start of the file is used. Sub-variants of both versions exist. ID3v1 When the MP3 standard was published in 1995, it did not include a method for storing file metadata. In 1996 Eric Kemp proposed adding a 128-byte suffix to MP3 files, which would store useful information such as an artist's name or a related album title. Kemp deliberately placed ...

Metadata
Metadata (or metainformation) is "data that provides information about other data", but not the content of the data itself, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, and permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of Statistical data type, statistical data. * Statistical metadata – also called process data, may ...

Null Character
The null character is a control character with the value zero. Many character sets include a code point for a null character including Unicode (Universal Coded Character Set), ASCII (ISO/IEC 646), Baudot, ITA2 codes, the C0 control code, and EBCDIC. In modern character sets, the null character has a code point value of zero which is generally translated to a single code unit with a zero value. For instance, in UTF-8, it is a single, zero byte. However, in Modified UTF-8 the null character is encoded as two bytes : . This allows the byte with the value of zero, which is not used for any character, to be used as a string terminator. Originally, its meaning was like NOP when sent to a printer or a terminal, it had no effect (although some terminals incorrectly displayed it as space). When electromechanical teleprinters were used as computer output devices, one or more null characters were sent at the end of each printed line to allow time for the mechanism to return to the fir ...

Computer File Formats
A file format is a standard way that information is encoded for storage in a computer file. It specifies how bits are used to encode information in a digital storage medium. File formats may be either proprietary or open. Some file formats are designed for very particular types of data: PNG files, for example, store bitmapped images using lossless data compression. Other file formats, however, are designed for storage of several different types of data: the Ogg format can act as a container for different types of multimedia including any combination of audio and video, with or without text (such as subtitles), and metadata. A text file can contain any stream of characters, including possible control characters, and is encoded in one of various character encoding schemes. Some file formats, such as HTML, scalable vector graphics, and the source code of computer software are text files with defined syntaxes that allow them to be used for specific purposes.

XBin
XBin, or ''eXtended Binary'', is a file format for saving IBM PC text mode images. Essentially an extension to the normal raw-image BIN (raw memory copy of text mode video memory) files, it provides an enhanced means for saving console graphics superior to ANSI graphics. The format was created by Belgian programmer ''Tasmaniac'' of ACiD, partly in response to the demand for a solution to save images in the BIN image format, which offered no insight as to the size/width of the image. XBin stores its width information internally so that a programmer or user does not need to define this information more than once, an inherent problem with plain BIN files. XBin also had several notable features above and beyond that of standard text images saved in ANSI format in that it took further advantage of the text mode environment by (optionally) storing alternate palette color information, supporting modified character set fonts and its own simple compression system.

Standard Architecture For Universal Comment Extensions
Standard Architecture for Universal Comment Extensions or ''SAUCE'', as it is most commonly known, is an open metadata protocol for tagging and describing ASCII text files and other files, most of which generally center on or date back to the era of BBSing. SAUCE is very similar in nature to the MP3 ID3 tag format created in 1996 in that it carries metadata such as the title, author (artist), organization (group), as well as specific hierarchical datatype information depending on what type of file it is describing. The SAUCE protocol was invented and developed by the Belgian programmer known by the pseudonym ''Tasmaniac'' of ACiD An acid is a molecule or ion capable of either donating a proton (i.e. Hydron, hydrogen cation, H+), known as a Brønsted–Lowry acid–base theory, Brønsted–Lowry acid, or forming a covalent bond with an electron pair, known as a Lewis ..., who later went on to create the XBin image format, in 1994, two years before ID3 was established. ...

Vorbis Comment
A Vorbis comment is a metadata container used in the Ogg file format (with Vorbis, FLAC, Theora, Speex and Opus codecs). It allows information such as the title, artist, album, track number or other information about the file to be added to the file itself. However, as the official Ogg Vorbis documentation notes, “ he comment headeris meant for short, text comments, not arbitrary metadata; arbitrary metadata belongs in a separate logical bitstream (usually an XML stream type) that provides greater structure and machine parseability.” Instead, the intended function of Vorbis comments is to approximate the kind of information that might be hand-inked onto a blank faced CD-R or CD-RW: a few lines of notes briefly detailing the content. Format A Vorbis tag is a list of fields in the format FieldName=Data. The field name can be composed of printable ASCII characters, 0x20 (''space'') through 0x7D (‘}’), with 0x3D (‘=’) and 0x7E (‘~’) excluded. It is case insensitive, ...

CD-Text
CD-Text is an extension of the Red Book Compact Disc specifications standard for audio CDs. It allows storage of additional information (e.g. album name, song name, and artist name) on a standards-compliant audio CD. The specification for CD-Text was included in the Multi-Media Commands Set 3 R01 (MMC-3) standard, released in September 1996 and backed by Sony. It was also added to new revisions of the Red Book. The actual text is stored in a format compatible with Interactive Text Transmission System (ITTS), defined in the IEC 61866 standard. The ITTS standard is also applied in the MiniDisc format, as well as in [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Audio Interchange File Format
Audio Interchange File Format (AIFF) is an audio file format standard used for storing sound data for personal computers and other electronic audio devices. The format was developed by Apple Inc. in 1988 based on Electronic Arts' Interchange File Format (IFF, widely used on Amiga systems) and is most commonly used on Apple Macintosh computer systems. The audio data in most AIFF files is uncompressed pulse-code modulation (PCM). This type of AIFF file uses much more disk space than lossy formats like MP3—about 10 MB for one minute of stereo audio at a sample rate of 44.1 kHz and a bit depth of 16 bits. There is also a compressed variant of AIFF known as AIFF-C or AIFC, with various defined compression codecs. In addition to audio data, AIFF can include loop point data and the musical note of a sample, for use by hardware samplers and musical applications. The file extension for the standard AIFF format is .aiff or .aif. For the compressed format the preferred suffi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
