A FOURCC (literally, four character code) is a sequence of four bytes used to uniquely identify data formats. Originally used in the Amiga IFF file format, the idea was reused to identify data types in Apple's AIFF format and Microsoft's RIFF format, and later in QuickTime and DirectShow. Four byte identifiers are useful because they can be made up of four human-readable characters with mnemonic qualities, while still fitting in the four byte memory space typically allocated for integers in 32-bit systems. In 1985 Electronic Arts introduced the Interchange File Format (IFF) meta-format (family of file formats), originally devised for use on the Amiga. These files consisted of a sequence of "chunks" which could contain arbitrary data, each chunk prefixed by a four-byte ID. This IFF was adopted by a number of developers including Apple for AIFF files and Microsoft for RIFF files (which were used as the basis for the AVI and WAV file format). Apple referred to many of these codes as OSTypes. Microsoft and Windows developers refer to their four-byte identifiers as FourCCs or Four Character Codes. FOURCC codes were also adopted by Microsoft to identify data formats used in DirectX, specifically within DirectShow and DirectX Graphics. One of the most well-known uses of FourCCs is to identify the video codec used in AVI files. Common identifiers include DIVX, XVID, and H264. For audio codecs, AVI and WAV files use a two-byte identifier, usually written in hexadecimal (such as 0055 for MP3). In QuickTime files, these two-byte identifiers are prefixed with the letters 'ms' to form a four-character code. RealMedia files also use four character codes, however the actual codes used differ from those found in AVI or QuickTime files. Other file formats that make important use of the four-byte ID concept are the Standard MIDI File Format, the PNG image file format, the 3DS (3D Studio Max) mesh file format and the ICC profile format.
