DCT is a digital recording component video videocassette format developed. Betamax - Three Sony Betamax VCRs built for the American market. To three related videocassette formats for the NTSC and PAL/SECAM television. Them to the Institute of Radio Engineers in San Francisco on May 16,1946. Sony PCM – F1 Digital Audio processor Pal / Secam. Sony SL – F1E Portable video cassette recorder (Betamax) Condition: good, working status (tbc). Paired with the SL-F1 Betamax deck, the PCM-F1 was the first portable, battery-operated digital recording system. A few brave souls even went so far as to make multitrack recordings using two. A few years after the PCM adaptor's introduction, Sony introduced in 1987 a new cassette-based format for digital audio recording called DAT (Digital Audio Tape). DAT was a much more portable and less-cumbersome format to use than a PCM adaptor-based system, since DAT no longer relied on a separate video cassette recorder.
Ampex DCT VCR Media type, Read mechanism Write mechanism Developed by Dimensions 19 mm tape Usage DCT is a format developed and introduced by in 1992. It was based on the format, and unlike the uncompressed recording scheme of D1, it was the first digital videotape format to use. Like D1 (and ), it uses a similar cassette loaded with 3/4' (19mm) width tape. One of the models of VCR released for the format was the Ampex DCT-1700D. The type of data compression used by the format, (DCT), shares the same acronym as the format, but the meaning is different for the latter (the format's acronym meaning Data Component Technology). DST , a data-only version of DCT, was also developed by Ampex at the same time for the backup and archiving of data from servers and other enterprise-oriented IT systems.

It was developed in Germany, based on magnetic wire recording, devices that record and play back audio and video using magnetic tape are tape recorders and video tape recorders. A device that stores data on magnetic tape is a tape drive. Magnetic tape revolutionized broadcast and recording, when all radio was live, it allowed programming to be recorded. At a time when gramophone records were recorded in one take, it allowed recordings to be made in multiple parts, which were then mixed and edited with tolerable loss in quality. It was a key technology in computer development, allowing unparalleled amounts of data to be mechanically created, stored for long periods.
Nowadays, other technologies can perform the functions of magnetic tape, in many cases, these technologies are replacing tape. Despite this, innovation in the technology continues, and Sony, over years, magnetic tape made in the 1970s and 1980s can suffer from a type of deterioration called sticky-shed syndrome. Caused by hydrolysis of the binder of the tape, it can render the tape unusable, the oxide side of a tape is the surface that can be magnetically manipulated by a tape head.
This is the side that stores the information, the side is simply a substrate to hold the tape together. The name originates from the fact that the side of most tapes is made of an oxide of iron.
Magnetic tape was invented for recording sound by Fritz Pfleumer in 1928 in Germany, based on the invention of magnetic wire recording by Oberlin Smith in 1888, pfleumers invention used a ferric oxide powder coating on a long strip of paper. This invention was developed by the German electronics company AEG, which manufactured the recording machines and BASF. In 1933, working for AEG, Eduard Schuller developed the ring-shaped tape head, previous head designs were needle-shaped and tended to shred the tape. An important discovery made in this period was the technique of AC biasing, due to the escalating political tensions, and the outbreak of World War II, these developments were largely kept secret. A wide variety of recorders and formats have developed since, most significantly reel-to-reel, the practice of recording and editing audio using magnetic tape rapidly established itself as an obvious improvement over previous methods. Many saw the potential of making the same improvements in recording television, television signals are similar to audio signals.
A major difference is that video signals use more bandwidth than audio signals, existing audio tape recorders could not practically capture a video signal 2. – Ampex is an American electronics company founded in 1944 by Alexander M. The name AMPEX is an acronym, created by its founder, at one time public, the remaining ongoing business unit was acquired by Delta Information Systems in October 2014, with the original parent, Ampex Corporation, ceasing operations in October 2014. Ampexs first great success was a line of tape recorders developed from the German wartime Magnetophon system at the behest of Bing Crosby. Ampex quickly became a leader in audio technology, developing many of the analog recording formats for both music and movies that remained in use into the 1990s. They also introduced multi-track recording, slow-motion and instant playback television, Ampexs tape business was rendered obsolete during the 1990s, and the company turned to digital storage products.
They never managed to become a player in this field, russian inventor Alexander Matthew Poniatoff established the company in San Carlos, California, in 1944 as the Ampex Electric and Manufacturing Company. The name came from his initials plus ex to avoid using the name AMP already in use, during World War II, Ampex was a small manufacturer of high quality electric motors and generators for radars that used alnico 5 magnets from General Electric.

Ampexs first offices were at 1313 Laurel St. San Carlos California, near the end of the war, while serving in the U.
Army Signal Corps, Major Jack Mullin was assigned to investigate German radio and electronics experiments. He discovered the Magnetophons with AC biasing on a trip to Radio Frankfurt, the device produced much better fidelity than shellac records. Mullin acquired two Magnetophon recorders and 50 reels of BASF Type L tape, and brought them to America and he demonstrated them to the Institute of Radio Engineers in San Francisco on May 16,1946.
Bing Crosby, a big star on radio at the time, was receptive to the idea of pre-recording his radio programs and he disliked the regimentation of live broadcasts, and much preferred the relaxed atmosphere of the recording studio. This may have been what Crosby was hoping to avoid, as that was the argument Crosby used with the network when he asked to use transcription disc recordings of his show.
Those recordings were made directly from the live east coast show, in June 1947, Mullin, who was pitching the technology to the major Hollywood movie studios, got the chance to demonstrate his modified tape recorders to Crosby. When Crosby heard a demonstration of Mullins tape recorders, he saw the potential of the new technology. Ampex was finishing its prototype of the Model 200 tape recorder, after a successful test broadcast, ABC agreed to allow Crosby to pre-record his shows on tape. Crosby immediately appointed Mullin as his engineer and placed an order for $50,000 worth of the new recorders so that Ampex could develop a commercial production model from the prototypes.
Crosby Enterprises was Ampexs West Coast representative until 1957, the companys first tape recorder, the Ampex Model 200A, was first shipped in April 1948. The first two units, serial numbers 1 and 2, were used to record the Bing Crosby Show 3. – Component video is a video signal that has been split into two or more component channels. In popular use, it refers to a type of component analog video information that is transmitted or stored as three separate signals. Component video can be contrasted with composite video in all the video information is combined into a single line level signal that is used in analog television. Like composite, component-video cables do not carry audio and are paired with audio cables.
When used without any qualifications the term component video usually refers to analog YPBPR component video with sync on luma. Reproducing a video signal on a device is a straightforward process complicated by the multitude of signal sources. DVD, VHS, computers and video game consoles all store, process and transmit video signals using different methods, one way of maintaining signal clarity is by separating the components of a video signal so that they do not interfere with each other. A signal separated in this way is called component video, S-Video, RGB and YPBPR signals comprise two or more separate signals, and thus are all component-video signals. In the past, for most consumer-level applications, analog component video was used, however, component video is capable of carrying various signals, such as 480i, 480p, 576i, 576p, 720p, 1080i, 1080p, 2160p and beyond. Many new high definition TVs support the use of component video up to their native resolution, most modern computers offer this signal via a VGA port.
Many televisions, especially in Europe, utilize RGB via the SCART connector, all arcade games, other than early vector and black-and-white games, use RGB monitors. In addition to the red, green and blue color signals, sync on luma, where the Y signal from S-Video is used alongside the RGB signal only for the purposes of sync. Composite sync is common in the European SCART connection scheme, RGBS requires four wires – red, green, blue and sync. If separate cables are used, the cable is usually colored yellow or white. Separate sync is most common with VGA, used worldwide for analog computer monitors and this is sometimes known as RGBHV, as the horizontal and vertical synchronization pulses are sent in separate channels. If separate cables are used, the lines are usually yellow and white, yellow and black, or gray.
Sync on Green is less common, and while some VGA monitors support it, sony is a big proponent of SoG, and most of their monitors use it. Like devices that use video or S-video, SoG devices require additional circuitry to remove the sync signal from the green line 4. – Videotape is magnetic tape used for storing video and usually sound in addition.

Information stored can be in the form of either a signal or digital signal. Videotape is used in video tape recorders or, more commonly, videocassette recorders and camcorders. Videotapes are also used for storing scientific or medical data, such as the produced by an electrocardiogram. Tape is a method of storing information and thus imposes delays to access a portion of the tape that is not already under the heads. The early 2000s saw the introduction and rise to prominence of high quality video recording media such as hard disks.
Since then, videotape has been relegated to archival and similar uses. The electronics division of entertainer Bing Crosbys production company, Bing Crosby Enterprises, overall the picture quality was still considered inferior to the best kinescope recordings on film.
Bing Crosby Enterprises hoped to have a version available in 1954. The BBC experimented from 1952 to 1958 with a high-speed linear videotape system called VERA and it used half-inch tape traveling at 200 inches per second. RCA demonstrated the magnetic recording of both black-and-white and color television programs at its Princeton laboratories on December 1,1953. The high-speed longitudinal tape system, called Simplex, in development since 1951, could record, the color system used half-inch tape to record five tracks, one each for red, blue, green, synchronization, and audio. The black-and-white system used quarter-inch tape with two tracks, one for video and one for audio, both systems ran at 360 inches per second. RCA-owned NBC first used it on The Jonathan Winters Show on October 23,1956 when a song sequence by Dorothy Collins in color was included in the otherwise live television program. BCE demonstrated a color system in February 1955 using a longitudinal recording on half-inch tape.
CBS, RCAs competitor, was about to order BCE machines when Ampex introduced the superior Quadruplex system, BCE was acquired by 3M Company in 1956. Quad employed a transverse four-head system on a tape. On January 22,1957, the NBC Television game show Truth or Consequences, produced in Hollywood, Ampex introduced a color videotape recorder in 1958 in a cross-licensing agreement with RCA, whose engineers had developed it from an Ampex black-and-white recorder 5.
– Betamax is a consumer-level analog-recording and cassette format of magnetic tape for video. It was developed by Sony and was released in Japan on May 10,1975, the first Betamax introduced in the United States was the LV-1901 console, which included a 19-inch color monitor, and appeared in stores in early November 1975. The cassettes contain 0. 50-inch-wide videotape in a similar to that of the earlier, professional 0. Betamax is obsolete, having lost the videotape format war to VHS, production of Betamax recorders ceased in 2002, new Betamax cassettes were available until March 2016, when Sony stopped making and selling them. Like the rival videotape format VHS, Betamax has no guard band, the suffix -max, from the word maximum, was added to suggest greatness.
In 1977, Sony issued the first long-play Betamax VCR, the SL-8200 and this VCR had two recording speeds, normal, and the newer half speed. This provided two hours recording on the L-500 Beta videocassette, the SL-8200 was to compete against the VHS VCRs, which allowed up to 4, and later 6 and 8, hours of recording on one cassette.
Sanyo marketed a version as Betacord, which also was casually called Beta, in addition to Sony and Sanyo, Beta-format video recorders were manufactured and sold by Toshiba, Pioneer, Murphy, Aiwa, and NEC. The Zenith Electronics Corporation and WEGA Corporations contracted with Sony to produce VCRs for their product lines, the department stores Sears and Quelle sold Beta-format VCRs under their house brands, as did the RadioShack chain of electronic stores.
Betamax and VHS competed in a format war, which saw VHS win in most markets. For the professional and broadcast video industry, Sony derived Betacam from Betamax, released in 1982, Betacam became the most widely used videotape format in ENG, replacing the.75 in wide U-matic tape format.
But in the key area of recording, Betacam and Betamax are completely different. Sony also offered a range of industrial Betamax products, a Beta I-only format for industrial and institutional users and these were aimed at the same market as U-Matic equipment, but were cheaper and smaller. The arrival of Betacam reduced the demand for both industrial Beta and U-Matic equipment, Betamax also had a significant part to play in the music recording industry, when Sony introduced its PCM digital recording system as an encoding box/PCM adaptor that connected to a Betamax recorder. The Sony PCM-F1 adaptor was sold with a companion Betamax VCR SL-2000 as a digital audio recording system. Many recording engineers used this system in the 1980s and 1990s to make their first digital master recordings and this feature is discussed in more detail on Peep Search. Sony believed that the M-Load transports used by VHS machines made copying these trick modes impossible, betaSkipScan is now available on miniature M-load formats, but even Sony was unable to fully replicate this on VHS. BetaScan was originally called Videola until the company made the Moviola threatened legal action 6.
– 1 inch type B VTR is a reel-to-reel analog recording video tape format developed by the Bosch Fernseh division of Bosch in Germany in 1976. Video is recorded on an FM signal with a bandwidth of 5.5 MHz, three longitudinal audio tracks are recorded on the tape as well, two audio and one Linear timecode track. BCN50 VTRs were used at the 1980 Summer Olympics in Moscow, the picture quality was excellent, and standard R/P machines, digital frame store machines, reel-to-reel portables, random access cart machines, and portable cart versions were marketed. Echo Science Corporation, a United States company, made units like a BCN1 for the U. Military for a time in the 1970s. Echo Science models were Pilot 1, Echo 460, Pilot 260.
BCR was a pre BCN VTR, made with Philips, the large scanner made it not useful, BCN40 BCN50 BCN20 BCWQ Effects control option for digital framestore, for freeze frame, quad split and mirror effects. BNC51 BCN5 BCN100 BCN52 BCN21 BCN53 HR-400, RCA also sold the BCN50 as an HR-400, Ruxton Video in Burbank used modified BCNs for 24 Frame playback to TVs used on movie studio sets. Thus the TVs had no flicker when seen on film, due to the frame rate. Bill Hogan of Ruxton Ltd received in 1981 an Academy Award for Technical Achievement for his 24frame TV work, Image Transform in Universal City, co-founded by Ken Holland, in 1970, used specially modified BCNs to record 24-frame video also, but for their Image Vision system. The BCN would record and play back 24-frame video at 10 MHz bandwidth, with twice the standard 525-line NTSC resolution, to record this the headwheel and capstan ran at twice normal speed. Modified 24 frame/s 10 MHz Bosch Fernseh KCK-40 professional video cameras were used on the set and this was a custom pre-HDTV video system. This Image Vision recording could then be recorded to film on a modified 3M Electron Beam film recorder, Image Transform had modified other gear for this process.
At its peak, this system was used to make Monty Python Live at the Hollywood Bowl in 1982 and this was the first major use of early electronic cinema technology using a film recorder for Film out. Electronovision was also a pre-process like Image Vision, merlin Engineering also worked on the BCNs Wide bandwidth,10 MHZ, BCN modification.
Bell and Howell used special BCNs for mass VHS duplication and these specially-modified BCN VTRs could play back movies at two times the normal speed. In addition, the signals were also were at two times speed as well. For proper playback, the headwheel and capstan ran at twice normal speed. Specially modified VHS recorders could record this video, in doing this, the duplication plant could output twice the product than normal videocassette duplicating systems.

Sony Betamax: Home VCRs Ahead of Their Time If you are having a nostalgic moment and want to play vintage video cassette tapes or understand the development of home video technology, a Sony Beta home VCR may serve your needs.
Early home video playing and recording systems can still provide considerable entertainment. Understanding more about this early VCR technology can help you make an informed and specific selection. What is a Betamax home video player? One of the early home video players, the Sony Betamax home VCR was introduced to the general public in 1975. The player was equipped to play its brand of videocassettes. This technology allowed viewers to use the machine to 'Watch whatever whenever,' as one advertisement put it.

Television viewers could videotape a show broadcasting on one channel while watching another, an experience which was a technological novelty at the time. Viewers could also play prerecorded movies on the video player. How do you operate this machine?. Find a power source: First, plug your home video recording equipment into a standard wall socket or power strip, checking that all connections are fully operational. Connect the player to the television: Following the manufacturer's specifications included in the manual or instructions, attach the player to the television you intend to use. Put in a Beta tape: These tapes were manufactured specifically to fit this player. Viewers can watch commercially produced and prerecorded films or home movies on a Beta tape.
Both can be bookmarked for later review. What are some available models or types of Beta player?.
SL-HF400 Super Beta Hi-Fi Betamax VCR with remote: This includes both the machine and the remote control player for ease of operation. Super Betamax SL-HF1000: This Betamax machine was a VCR with advanced recording and playing capabilities for its time. SL-HF2000 Super Beta HiFi VCR: This was the last Beta made. Compared to others of its kind, it is lightweight. Do Betamax players play VHS tapes? Betamax and VHS were competitors during most of the early development of the home VCR recorder market.
VHS had the capacity to record for two hours per cassette. Betamax, with its smaller, one-hour tapes, produced recordings with more faithful audio and video. Some customers preferred the length of the VHS cassettes, while others preferred the video quality of the Beta versions. Because of this history of competition, Betamax and VHS machines are not compatible. The VHS and Beta tapes are different sizes and the method of encoding is not the same.
