Development of the video recording standard known today as DV began in 1993. The first DV camcorder—the Sony DCR-VX1000—appeared two years later, and the DV industry has been on a rocketship ride ever since.
One reason DV became technically feasible was because new compression techniques made video data files much more compact at the same time that processing chips in camcorders and PCs were becoming more powerful. A DV tape recording or computer file requires only one-fifth the data bits of the uncompressed digital sig-nal, and the picture quality is almost undegraded.
