DV
Digital video is the key to content when streaming media. Digital video is an alternative way of storing or distributing video. Digital video is usually converted from an analog video source. A digital video signal is represented in '1's and '0's, whereas an analog video signal is represented by a fluctuating voltage signal that is stored on magnetic tape. This difference is similar to the difference between analog audio and digital audio. DV is also known as a minituarized tape format that uses 4:1:1 or 4:2:0 chroma sampling, popular among consumers in the 1990s and early 2000s.
