DV

DV is a format for storing digital video. It was launched in 1995 with joint efforts of leading producers of video camera recorders.

The original DV specification, known as Blue Book, was standardized within the IEC 61834 family of standards. These standards define common features such as physical videocassettes, recording modulation method, magnetization, and basic system data in part 1. Part 2 describes the specifics of 525-60 and 625-50 systems. The IEC standards are copyrighted publications available for purchase from IEC or ANSI.

In 2005, DV was superseded by the successor format HDV, which used the same tape format with a different video codec. Some cameras at the time had the ability to switch between DV and HDV recording modes.

DV compression

DV uses lossy compression of video while audio is stored uncompressed. An intraframe video compression scheme is used to compress video on a frame-by-frame basis with the discrete cosine transform (DCT).

Closely following ITU-R Rec. 601 standard, DV video employs interlaced scanning with the luminance sampling frequency of 13.5 MHz. This results in 480 scanlines per complete frame for the 60 Hz system, and 576 scanlines per complete frame for the 50 Hz system. In both systems the active area contains 720 pixels per scanline, with 704 pixels used for content and 16 pixels on the sides left for digital blanking. The same frame size is used for 4:3 and 16:9 frame aspect ratios, resulting in different pixel aspect ratios for fullscreen and widescreen video.

Dampfkessel Überwachungsverein

DÜVs (short for Dampfkessel Überwachungs-Verein, Steam Boiler Inspectorate Organization in English) were German organizations founded in the 19th century by a group of German entrepreneurs to ensure the technical safety of steam boilers, which was an immanent issue at that time.

The charter of the organizations stated they were founded "to prevent steam boiler explosions through regular, periodical inspections... to foster the implementation of all current and future improvements (regarding economic efficiency of the whole machine as well as energy efficiency of the fire engine) in the operation of steam boilers so that all members of the organization can benefit."

DÜVs were the predecessor of TÜVs.
