History

Professional and broadcast use

Open reel

A 1st practical agency videotape machines were a Quadruplex machines introduced by Ampex in the United States in 1956. Quad employed a transverse (scanning the tape across its width) four-head system on a two-inch (5.08 cm) tape, and linear heads for the soundtrack. The BBC experimented with a high-speed linear videotape system called VERA, but this was ultimately unfeasible, it used 1/2 inch (1.27 cm) tape traveling at 200 inches (5.08 m) per second, and all subsequent videotape systems have used helical scan.

Although Quad became the industry standard for 20 years, it had drawbacks such as an inability to freeze pictures, no picture search, and in early machines, a tape could only reliably be played back using the same set of hand-made tape heads, which wore out very quickly. Despite these problems, Quad could produce excellent images. Unfortunately, very few early videotapes still exist. The high cost of early videotapes meant that most broadcasters erased and reused them, and (in the United States) regarded videotape as simply a better and more cost-effective means of time-delaying broadcasts than the previous kinescope technology, which recorded television pictures onto photographic film. It was the four time zones of the continental United States which had made the system very desirable in the first place. However, some early broadcast videotapes have survived, including The Edsel Show, broadcast live in 1957, and 1958's An Evening With Fred Astaire, the oldest color broadcast videotape known to exist.

The next format to gain widespread usage was the 1" (Ii.54 cm) C-format videotape from the prevent of the 1970s onwards. It introduced features like shuttling & however framing, however a healthy & picture reproduction come-at-able on the format were inferior to Quad.

The first video cassettes

So, around 1969, Sony introduced the number 1 far flung streaming video cassette (anterior formats got utilized open reels), the 3/4" (1.905 cm) composite U-matic system, which it later refined to Broadcast Video U-matic or BVU. Sony continued its hold on the professional market with its ever-expanding 1/2" (One.Twenty-seven cm) component video Betacam family (introduced in 1982), which, in its digital variants, is however among a market leaders. Panasonic had some limited profits sustaining its MII system, but never can compare to Betacam inside terms of market part.

Going digital

A next step was a digital revolution. Among a foremost digital videos formats Sony's D1, which featured uncompressed digital component recording. Because D1 was highly expensive, a composite D2 and D3 (by Sony and Panasonic, severally) were introduced shortly when. Ampex introduced a number 1 compressed component recording by owning its Ampex DCT series in 1992. Panasonic trumped D1 by using its D5 format, which was uncompressed as well, however great deal other low-priced. JVC developed a S-VHS-based D9 format, which compresses video information inside how else similar to DVCPRO.

For camcorders, Sony adapted a Betacam rules by owning is Digital Betacam format, later as a result it higher by owning a other online-low-priced Betacam SX and MPEG IMX formats, and a semipro DV-based DVCAM system. Panasonic utilized its DV variant DVCPRO for all agent cameras, using a higher prevent format DVCPRO50 being a directly descendent.

High definition

A introduction of HDTV production necessitated a medium for storing high guide streaming videos references. Inside 1997, Sony bumped its Betacam series up to HD by using a HDCAM standard and its higher-prevent first cousin HDCAM SR. Panasonic's competing format for cameras was according to DVCPRO & known as DVCPRO HD. For VTR & archive utilize, Panasonic expanded a D5 specification to store compressed HD lakes & known as it D5 HD.

Consumer use

Home VCRs

A number one farm videocassette recorders were launched in the early 1970s, but it was non until a Japanese systems, Sony's Beta (1975) and JVC's VHS, were launched, that videotape moved into a mass market, sequent inside what come to become referred to as a "format wars". VHS eventually won, principally owing to its hanker recording instance in comparison Beta. VHS is however a leading consumer VCR format, since its follow-ups S-VHS and D-VHS never caught up on popularity. It has, still, wasted a battle against a nonlinear & disc depending DVD, and might probably turn into obsolete in the next pack years.

Camcorders

Around camcorders, however, a field was extra diverse; early camcorders typically took good-sized VHS tapes, however a greatest popularity for occasionally period shared out per 8mm video format (later replaced by Hi8 and its DV hybrid relative Digital8) and VHS-C (compact) tape. MiniDV is now a virtually all popular format for consumer camcorders, providing touching-broadcast quality videos & sophisticated nonlinear redactiin capability on consumer devices; yet, though designed as a digital successor to VHS, MiniDV VCRs are non widely available outside office circles. Sony tried to introduce the recently camcorder tape by owning MicroMV, however consumer interest has been moo due to the proprietary nature & severity of the format and limited trprevent lines for all the world but on line-end Windows streaming videos editors. For high definition, a virtually all promising body seems to become a freshly MiniDV-depending HDV, which uses MiniDV medithe to store a about broadcast-quality HDTV data stream.

There has been the trend, largely spearheaded by Hitachi, Panasonic, and Sony, to sell consumer camcorders based on DVD-personal media, however sales person users assume DVD camcorders as well limited for even even all the world however casual utilise & keep around remained sustaining digital videotape or switched to firm-state or firm disk storage.
