Sony PCM-501ES
A PCM adaptor is a device that encodes digital audio as video for recording on a videocassette recorder. The adapter also has the ability to decode a video signal back to digital audio for playback. This digital audio system was used for mastering early compact discs. Operation 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 bandwidths. A means of converting digital audio into a video format was necessary. Such an audio recording system includes two devices: the PCM adaptor, which converts audio into pseudo-video, and the videocassette recor ...

Interlaced Image
Interlaced video (also known as interlaced scan) is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth. The interlaced signal contains two fields of a video frame captured consecutively. This enhances motion perception to the viewer, and reduces flicker by taking advantage of the characteristics of the human visual system. This effectively doubles the time resolution (also called ''temporal resolution'') as compared to non-interlaced footage (for frame rates equal to field rates). Interlaced signals require a display that is natively capable of showing the individual fields in a sequential order. CRT displays and ALiS plasma displays are made for displaying interlaced signals. Interlaced scan refers to one of two common methods for "painting" a video image on an electronic display screen (the other being progressive scan) by scanning or displaying each line or row of pixels. This technique uses two fields to create a frame. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Videocassette
Videotape is magnetic tape used for storing video and usually sound in addition. Information stored can be in the form of either an analog or digital signal. Videotape is used in both video tape recorders (VTRs) and, more commonly, videocassette recorders (VCRs) and camcorders. Videotapes have also been used for storing scientific or medical data, such as the data produced by an electrocardiogram. Because video signals have a very high bandwidth, and stationary heads would require extremely high tape speeds, in most cases, a helical-scan video head rotates against the moving tape to record the data in two dimensions. Tape is a linear method of storing information and thus imposes delays to access a portion of the tape that is not already against the heads. The early 2000s saw the introduction and rise to prominence of high-quality random-access video recording media such as hard disks and flash memory. Since then, videotape has been increasingly relegated to archival and s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technics (brand)
is a Japanese audio brand established by Matsushita Electric (now Panasonic) in 1965. Since 1965, Matsushita has produced a variety of High fidelity, HiFi and other audio products under the brand name, such as Phonograph, turntables, amplifiers, radio receivers, tape recorders, CD players, loudspeakers, and digital pianos.

Betamax
Betamax (also known as Beta, and stylized as the Greek letter Beta, β in its logo) is a discontinued consumer analog Videotape, video cassette recording format developed by Sony. It was one of the main competitors in the videotape format war against its primary rival, VHS. Betamax was introduced in Japan on May 10, 1975, and launched in the United States later that year. Betamax was widely regarded, in part due to Sony's marketing, as offering superior picture quality compared to VHS. Its initial β1 speed provided 250 horizontal lines of resolution, compared to VHS's 240 lines, but early Beta tapes were limited to 60 minutes of recording time, making them impractical for recording movies or sporting events. To address this, Sony introduced the β2 speed, which doubled recording time to two hours but reduced resolution, negating its technical advantage. VHS's commercial success over Betamax was also driven by JVC's strategy of licensing the format broadly, spurring competition ...

Glass Master
In optical disc manufacturing, replication is the process of producing discs via methods that do not involve "burning" blank CD, DVD or other discs; the latter is known as duplication. The replication of optical discs involves: # the creation of a glass master from a client original master. # the creation of a nickel stamper from that glass master. # the injection molding of clear optical-grade polycarbonate substrates (clear discs) from that stamper. # the metallizing and lacquer Lacquer is a type of hard and usually shiny coating or finish applied to materials such as wood or metal. It is most often made from resin extracted from trees and waxes and has been in use since antiquity. Asian lacquerware, which may be c ...ing of those substrates to produce compact discs and DVDs.

Dropout Compensator
A drop-out compensator is an error concealment device that was commonly used in the analog video era to hide brief RF signal ''drop-outs'' on videotape playback caused by imperfections in or damage to the tape's magnetic coating. Most compensators worked by repeating earlier video scan lines over short periods of signal loss; one early such system, Mincom, was developed in the 1960s by the Minnesota Mining and Manufacturing Company, the company now known as 3M. Because of the high cost of the 3M device at the time, BBC R&D engineers developed a simpler, less expensive unit based on a sample-and-hold technique for in-house use. Dedicated drop-out compensators were eventually superseded by the incorporation of drop-out compensation functionality into timebase correctors based on analog-to-digital conversion and digital line stores. The advent of compressed digital video systems finally eliminated the need for line-based drop-out compensators. Most low-level media errors, such as ...

Transport (recording)
A transport is a device that handles a particular physical storage medium (such as magnetic tape, audio CD, CD-R, or other type of recordable media) itself, and extracts or records the information to and from the medium, to (and from) an outboard set of processing electronics that the transport is connected to. A transport houses no electronics itself for encoding and decoding the information recorded to and from a certain format of media. It only extracts and records information to the media, as well as handling mechanical operations for accessing the media itself, such as playing or rewinding a tape, or accessing the tracks on a disc. An example of a transport for a storage medium would be an audiophile-grade audio CD transport, which houses no digital-to-analog converter (DAC), unlike most ordinary audio CD players. Instead, the audio CD transport is connected to an external DAC via a coaxial ( SPDIF) or optical ( Toslink) digital audio connection to convert the digital audio ...

U-matic
U-matic, also known as -inch Type E Helical Scan or SMPTE E, is an analog recording videocassette format developed by Sony. First shown as a prototype in October 1969 and introduced commercially in September 1971, it was among the earliest video formats to house videotape inside a cassette, replacing the reel-to-reel systems common at the time. The format uses tape, earning it the nickname "three-quarter-inch" or simply "three-quarter," in contrast to larger open-reel formats like Type C videotape and quadruplex videotape. The name ''U-matic'' refers to the U-shaped tape path as it threads around the video drum. Unlike most cassette formats, U-matic's supply and take-up reels rotate in opposite directions during playback, fast-forward, and rewind—one clockwise, the other counterclockwise. Each cassette has an internal locking mechanism that secures the tape hubs during transport, and a spring-loaded door that protects the tape; this door automatically opens when the casse ...
