SMPTE 314M: Data structure for DV-based audio, data and compressed video – 25 and 50 Mb/s
SMPTE 370M: Data structure for DV-based audio, data and compressed video at 100 Mb/s 1080/60i, 1080/50i, 720/60p, 720/50pFor the purposes of this Web site, this family of related formats is described together, emphasizing the underlying encoding as it may be stored in media-independent files. The DV video format, however, was developed in the early 1990s as a media-dependent videocassette format. DV video signals are compressed using discrete cosine transforms (DCT) within each frame, like the the approach used with JPEG_DCT. DV does not use frame-to-frame temporal encoding like that employed by MPEG-2 and other MPEG formats. In the years after its introduction, similar but higher quality elaborations were offered by SONY (DVCAM) and Panasonic (DVCPRO, DVCPRO-50, DVCPRO HD), and these have found their place in professional television production.
DV signals are formatted for transfer between devices in 80-byte blocks referred to as DV-DIF data (DV Digital Interface Format), and these DV-DIF blocks can be stored as files in raw form (.dv or .dif extension) or wrapped in such file formats as AVI, QuickTime, and MXF.
