dv

DV is an abbreviation that can refer to several concepts depending on context. Two of the most common meanings are domestic violence and digital video.

Domestic violence refers to a pattern of coercive behavior used by one person to control another in an intimate or family relationship. It can include physical harm, sexual violence, emotional abuse, and economic deprivation, as well as threats and stalking. Abuse can occur in dating relationships, marriages, or within families and may be ongoing or escalate over time. Risk factors often involve gender-based power imbalances, past experiences of violence, and social or economic stress. The consequences are serious and wide-ranging, affecting physical and mental health, safety, and economic stability. Responses from society include protective orders, shelters, hotlines, counseling, and law enforcement, with a focus on safety planning, accountability, and support for victims and, when appropriate, children.

Digital video, or DV, is a family of digital video formats that emerged in the mid-1990s for consumer and professional camcorders. DV records video and digital audio on tape or via later digital workflows, enabling relatively straightforward transfer to computers for editing. Typical DV systems produce standard-definition video, with common resolutions around 720x480 (NTSC) or 720x576 (PAL) and two-channel 16-bit 48 kHz PCM audio, at a data rate near 25 Mbps. The format gave rise to variants such as DVCPRO and DVCAM, which offer different tape formats and compatibility. DV supported many early digital editing pipelines, but has been largely supplanted by higher-definition and tapeless workflows in recent years, though it remains used in some archival or vintage-production contexts.

Other uses of the acronym DV exist in technology and science, such as distance-vector routing in computer networks or design verification in hardware development; these meanings are context-specific and less common than the above.
