That was the price of the first videotape recorder, or VTR, a forerunner to the VCR — not the price of the first VCR.

For the first time, the Academy bestowed a Lifetime Achievement Award in the area of Technology and Engineering. Mark Cuban, owner of the Dallas Mavericks and founder of HDnet, presented the award to the original inventors of the videotape recorder: Charlie Ginsburg, Ray Dolby, Alex Maxey, Charlie Anderson, Fred Pfost and Shelby Henderson. The six men, all then working for Ampex, introduced the VR-1000, (later named the Ampex Mark IV) the first practical videotape recorder, to the world on 14 March 1956 at the National Association of Radio and Television Broadcasters convention in Chicago.

The Videotape recorder which used magnetic tape allowed TV stations to gather news, timeshift and record content without having to use or develop relatively expensive and single-use film stock while allowing for the tape to be reused.

Experiments included hatching quail eggs, but the chicks grew much slower than on Earth, and lacked heads. A videotape recorder was fixed 6 March using a soldering iron, the first time such repair equipment had been used in space.

Also, around 1956 British producer Joseph Arthur Rank brought three Electronicams to the United Kingdom to experiment but eventually was disappointed with the picture quality. The introduction of Ampex's videotape recorder in mid-1956 began to eliminate the need for Electronicam and similar systems, allowing electronic recording from live video cameras.

He awakens with a rare reaction from taking Viagra and he goes to the hospital. Some time later, Jamie goes to a restaurant and runs into Maggie, who is on a date. Bruce shows up and reveals Jamie has been promoted to the Chicago office. While packing to move to Chicago, Jamie finds the videotape recorder where he taped himself and Maggie talking about life.

The high- frequency bias technique, which made quality recording possible, was invented by Telefunken engineers and put into practical use by Poniatoff. Danish engineer Valdemar Poulsen's original magnetic recorder was previously only usable for telephony recording. In 1956, Ampex engineers created the world's first rotary head recorder, the VR-1000 videotape recorder. Poniatoff served as president of Ampex until 1955, when he was elected chairman of the board.

However, a year later in 1968, an agreement was reached between CFCN and CJLH to share space on the CJLH tower and building for technical equipment. On September 3, CFCN went on the air with a repeater station on channel 13. That same year, the station's first 2-inch black and white videotape recorder was installed, and a repeater in Brooks began operations, transmitting at low power on VHF channel 3.

In 1951, singer Bing Crosby’s company Bing Crosby Enterprises made the first experimental magnetic video recordings; however, the poor picture quality and very high tape speed meant it would be impractical to use. In 1956, Ampex introduced the first commercial Quadruplex videotape recorder, followed in 1958 by a color model. Offering high quality and instant playback at a much lower cost, Quadruplex tape quickly replaced kinescope as the primary means of recording television broadcasts.

Sarnoff with the first RCA videotape recorder in 1954 When Sarnoff was put in charge of radio broadcasting at RCA, he soon recognized the potential for television, i.e., the combination of motion pictures with electronic transmission. Schemes for television had long been proposed (well before World War I) but with no practical outcome. Sarnoff was determined to lead his company in pioneering the medium and met with Westinghouse engineer Vladimir Zworykin in 1928.

HDTV was invented at NHK Science & Technology Research Laboratories (Japan Broadcasting Corporation's Science & Technical Research Laboratories). The research for HDTV started as early as the 1960s, though a standard was proposed to the ITU-R (CCIR) only in 1973. By the 1980s, a high definition television camera, cathode-ray tube, videotape recorder, and editing equipment, among others, had been developed. In 1982 NHK developed MUSE (Multiple sub-Nyquist sampling encoding), the first HDTV video compression and transmission system.

The "Classic 39" syndicated episodes of The Honeymooners were filmed using Electronicam (as well as the daily five-minute syndicated series Les Paul & Mary Ford At Home in 1954–55), but with the introduction of a practical videotape recorder only one year away, the Electronicam system never saw widespread use. The DuMont network did not survive into the era of videotape, and in order to gain clearances for its programs, was heavily dependent on kinescopes, which it called Teletranscriptions.

Mullin continued to work for Crosby to develop a videotape recorder (VTR). Television production was mostly live television in its early years, but Crosby wanted the same ability to record that he had achieved in radio. The Fireside Theater (1950) sponsored by Procter & Gamble, was his first television production. Mullin had not yet succeeded with videotape, so Crosby filmed the series of 26-minute shows at the Hal Roach Studios, and the "telefilms" were syndicated to individual television stations.

High-quality pulse-code modulation (PCM) audio requires a significantly larger bandwidth than a regular analog audio signal. For example, a 16-bit PCM signal requires an analog bandwidth of about 1-1.5 MHz compared to about 15-20 kHz of analog bandwidth required for an analog audio signal. A standard analog audio recorder cannot meet this requirement. One solution arrived at in the early 1980s, was to use a videotape recorder, which is capable of recording signals with higher bandwidth.

The source of this recording is the mono audio track of a primitive open-reel video recording made by Purple's US label at the time, Tetragrammaton Records. The video recording was made from the audience with a (then) state-of-the-art Sony 1/2 inch reel-to-reel videotape recorder and portable camera, with an open air microphone to capture the sound. The black and white picture quality of the video was poor, but the audio was quite acceptable. When Warner Bros.

With the advent of television, broadcasters quickly realised the limitations of live television broadcasts and they turned to broadcasting feature films from release prints directly from a telecine. This was before 1956 when Ampex introduced the first Quadruplex videotape recorder (VTR) VRX-1000. Live television shows could also be recorded to film and aired at different times in different time zones by filming a video monitor. The heart of this system was the kinescope, a device for recording a television broadcast to film.

The history of the videocassette recorder follows the history of videotape recording in general. In 1953, Dr. Norikazu Sawazaki developed a prototype helical scan video tape recorder.SMPTE Journal: Publication of the Society of Motion Picture and Television Engineers, Volume 96, Issues 1-6; Volume 96, page 256, Society of Motion Picture and Television Engineers Ampex introduced the quadruplex videotape professional broadcast standard format with its Ampex VRX-1000 in 1956. It became the world's first commercially successful videotape recorder using two-inch (5.1 cm) wide tape.

Crosby gave one of the first production models to musician Les Paul, which led directly to Paul's invention of multitrack recording. Working with Mullin, Ampex rapidly developed two- track stereo and then three-track recorders. Spurred on by Crosby's move into TV in the early 1950s, Mullin and Ampex developed a working monochrome videotape recorder by 1956 and a version to record in color later on, both created to record Crosby's TV shows. Through the rest of his life, Mullin continued to follow new ideas.

He worked as an engineer at AM-radio station KQW (now KCBS). He joined Ampex in 1951, and remained there until his retirement in 1986, holding the title Vice President of Advanced Technology. The engineering team that helped created the videotape recorder while working for Ampex under his direction were Charles Andersen, Ray Dolby, Shelby Henderson, Fred Pfost, and Alex Maxey. Ginsburg was elected a member of the National Academy of Engineering in 1973, being cited for invention and pioneering development of video magnetic tape recording for instant playback.

Time base correction is a technique to reduce or eliminate errors caused by mechanical instability present in analog recordings on mechanical media. Without time base correction, a signal from a videotape recorder (VTR) or videocassette recorder (VCR) cannot be mixed with other, more time stable devices found in television studios and post-production facilities. Most broadcast quality VCRs have simple time base correctors built in though external time base correctors (TBCs) are often used. Some high end domestic analog video recorders and camcorders also include a TBC circuit, which typically can be switched off if required.

The DAT or Digital Audio TapeThe first digital audio recorders were reel-to-reel decks introduced by companies such as Denon (1972), Soundstream (1979) and Mitsubishi. They used a digital technology known as PCM recording. Within a few years, however, many studios were using devices that encoded the digital audio data into a standard video signal, which was then recorded on a U-matic or other videotape recorder, using the rotating-head technology that was standard for video. A similar technology was used for a consumer format, Digital Audio Tape (DAT) which used rotating heads on a narrow tape contained in a cassette.

Imperial College TV (ICTV) is Imperial College Union's TV station, founded in 1969 and operated from a small TV studio in the Electrical Engineering block. The department had bought an early AMPEX Type A 1-inch videotape recorder and this was used to produce an occasional short news programme which was then played to students by simply moving the VTR and a monitor into a common room. A cable link to the Southside halls of residence was laid in a tunnel under Exhibition Road in 1972. Besides the news, early productions included a film of the Queen opening what was then called College Block.

The sampling rate dictates the upper range of the frequency response, whereas the bit depth dictates the dynamic range and signal to noise ratios. Starting in 1992, the ALESIS Corporation, a company which made digital drum machines and inexpensive analog audio mixers introduced the first multitrack, eight track, project studio, digital 8 track machine. It was named the ADAT, after the earlier 2 track digital recorders of the time known as DAT (Digital Audio Tape), which were based upon a small spinning head, similar to a consumer video recorder. The ADAT machine recorded its data in an already well-established consumer format based on VHS videotape recorder technology.

The three Series 2 episodes that remain missing are "The Loneliness of the Long Distance Walker", "A Stripe for Frazer" and "Under Fire".The missing episodes at the BBC Treasure Hunt site, URL accessed 4 June 2006 The only currently remaining hope for recovery is either that the lost episodes were recorded off-air during their original UK broadcasts using an early videotape recorder such as a Shibaden or Sony CV-2000 machine, or 16 mm tele-recordings being saved from being junked. However these three episodes were among the 67 adapted for BBC Radio in the 1970s, and recordings of the radio episodes still exist.

Another solution was transverse-scan technology, developed by Ampex around 1954, in which the recording heads are mounted on a spinning drum and record tracks in the transverse direction, across the tape. By recording on the full width of the tape rather than just a narrow track down the center, this technique achieved a much higher density of data per linear centimeter of tape, allowing a lower tape speed of 15 inches per second to be used. The Ampex VRX-1000 became the world's first commercially successful videotape recorder in 1956. It uses the 2″ quadruplex format, using two-inch (5.1 cm) tape. Because of its price, the Ampex VRX-1000 could be afforded only by the television networks and the largest individual stations.

Once CDs were commercially introduced in 1982, tapes recorded on the PCM-1600 were sent to the CD pressing plants to be used to make the glass master disc for CD replication. Other examples include dbx, Inc.'s Model 700 system, which, similar to modern Super Audio CDs, used a high sample-rate delta-sigma modulation rather than PCM; Decca's 1970s PCM system, which used a videotape recorder manufactured by IVC for a transport; and Mitsubishi's X-80 digital recorder, a 6.4 mm (¼ in) open reel digital mastering format that used a very unusual sampling rate of 50.4 kHz. For high- quality studio recording, all of these formats were effectively made obsolete in the early 1980s by two competing reel-to-reel formats with stationary heads: Sony's DASH format and Mitsubishi's continuation of the X-80 recorder, which was improved upon to become the ProDigi format.

DuMont produced more than 20,000 television episodes during the decade from 1946 to 1956. Because the shows were created prior to the launch of Ampex's electronic videotape recorder in late 1956, all of them were initially broadcast live in black and white, then recorded on film kinescope for reruns and for West Coast rebroadcasts. By the early 1970s, their vast library of 35mm and 16mm kinescopes eventually wound up in the hands of "a successor network," who reportedly disposed of all of them in New York City's East River to make room for more recent-vintage videotapes in a warehouse. Although recovery of films that have been submerged for decades has been done (see The Carpet from Bagdad as an example), to date, there have been no salvage-diving efforts to locate or recover the DuMont archive that reportedly sits in the East River, and if it survived in that environment, most of the films were likely damaged.

A Panasonic late-model VCR Omnivision Stereo 4-Head which supports VCRPlus+ The system has been licensed to television and VCR manufacturers in about 40 countries, but is branded under different names depending on the country. It is known as VCR Plus+, VCR Plus+ Silver and VCR Plus+ Gold in the United States and Canada; G-Code in Japan, China, New Zealand and Australia; VideoPlus+ in Ireland the United Kingdom and Japan; and ShowView in the rest of Europe as well as in South Africa. The system is branded as VideoPlus+/ShowView in Europe due to an existing trademark registration for "VCR" by Philips in that continent, and as G-Code (the "G" standing for the system's developer Gemstar) in Japan because VCR is not a common abbreviation there ("VTR," for videotape recorder, is used instead). Japan initially used the name Video Plus+ and later changed to G-Code, an example of this is the Victor (JVC) HR-880.

Centralcasting is a form of broadcast automation which operates on the presumption that large quantities of content are similar and are handled in a consistent or repetitive manner across multiple stations in a broadcast station group. While each individual station has its own digital on- screen graphic logo, call sign and identity, much of the content on a typical affiliate station consists of a common television network or syndicated programming with a small number of local broadcast programming time blocks employed for television news and sports television coverage, public affairs programming or local television commercials. Traditionally, many operations at an individual broadcast station were handled manually by broadcast engineering technicians at the local station. Network feeds would arrive by satellite; these would contain time cues to indicate when the station could switch to a prerecorded local station break from a videotape recorder, a local station ID from a character generator or a local program such as a newscast.

DAT was not the first digital audio tape; pulse-code modulation (PCM) was used in Japan by Denon in 1972 for the mastering and production of analogue phonograph records, using a 2-inch Quadruplex-format videotape recorder for its transport, but this was not developed into a consumer product. Denon's development dated from its work with Japan's NHK Broadcasting; NHK developed the first high-fidelity PCM audio recorder in the late 1960s. Denon continued development of their PCM recorders that used professional video machines as the storage medium, eventually building 8-track units used for, among other productions, a series of jazz records made in New York in the late 1970s. In 1976, another digital audio tape format was developed by Soundstream, using wide reel-to-reel tape loaded on an instrumentation recorder manufactured by Honeywell acting as a transport, which in turn was connected to outboard digital audio encoding and decoding hardware of Soundstream's own design. Soundstream's format was improved through several prototypes and when it was developed to 50 kHz sampling rate at 16 bits, it was deemed good enough for professional classical recording by the company's first client, Telarc Records of Cleveland, Ohio.

Belo also made an attempt to make WFAA-TV the market's exclusive NBC affiliate. To prevent the network from defecting, Carter's heirs—who were reluctant to comply to NBC's demands at first, out of their desire to continue Amon Carter Sr.'s legacy of pro-Fort Worth civic boosterism—agreed to move WBAP-TV's transmitter facilities to Cedar Hill and boost its effective radiated power to adequately cover Dallas; in the summer of 1964, it installed a transmitter at the Hill Tower (owned by the Dallas Newspapers) to feed the channel 5 antenna on a candelabra tower that was already shared by WFAA-TV and KRLD-TV (channel 4, now KDFW-TV); sister station WBAP-FM also moved its transmitter to this location. The move to Cedar Hill allowed channel 5 became the sole NBC affiliate for the entire Dallas–Fort Worth market on September 1, 1957 and subsequently, WFAA-TV became the area's exclusive ABC station. In October 1959, WBAP-TV installed the first color videotape recorder in Texas, allowing it the ability to record a 90-minute segment of programming and replay it in less than five minutes.
