The JVC AV-32WP2EN is a super top model Digital television with 100HZ Scan rate technology and top series high numbers of features. ,display system with increased field frequency ; digital scan converter means including field-memory means supplied with an input video signal of an interlaced television system having a selected plurality of fields per second different from PHILIPS 100HZ scan system.
The television receiver has an alphanumeric display which appears on the picture tube screen, to give the user data on the tuned channel number, colour settings and other operating data. The digital processor which generates the characters for display also controls the channel setting, etc., under the control of a digital remote control unit . The processor has an associated memory circuit for permanente tuning back up. The control of the capacitance diode tuner is achieved by the processor altering the dividing factor of a feedback loop to a phase/frequency comparator . The other input to the comparator is a divided frequency from a quartz oscillator.
The JVC AV-32WP2EN is 32 inches color tv with 100HZ frame rate TELEVISION a known arrangement, the frame rate of a television signal is doubled by using a field store. In a first operating mode, each field of the television signal is entered into the field store in this arrangement and read out twice at twice the frequency. In a second mode, only every second field is entered into the field store and read out four times at twice the frequency. In an arrangement for converting an original picture signal representing a sequence of frames, each of which is composed of two interlaced fields, into a converted picture signal which has a double field frequency with respect to the original picture signal, is for doubling the field frequency, for the purpose of noise reduction, motion compensation and line flicker reduction.
The JVC AV-32WP2EN features also Beam Scan Velocity modulation.
When the phosphor screen of a video signal reproducing apparatus, such as, the screen of the cathode ray tube in a television receiver, is scanned by an electron beam or beams so as to form a picture or image on the screen, the beam current varies with the luminance or brightness level of the input video signal. Therefore, each electron beam forms on the phosphor screen a beam spot whose size is larger at high brightness levels than at low brightness levels of the image so that sharpness of the reproduced picture is deteriorated, particularly at the demarcation between bright and dark portions or areas of the picture. Further, when a beam scanning the screen in the line-scanning direction moves across the demaraction or edge between dark and bright areas of the picture, for example, black and white areas, respectively, the frequency response of the receiver does not permit the beam intensity to change instantly from the low level characteristic of the black area to the high level characteristic of the white area. Therefore, the sharpness of the reproduced image is degraded at portions of the image where sudden changes in brightness occur in response to transient changes in the luminance or brightness of the video signal being reproduced. The increase in the beam current and in the beam spot size for bright portions of the reproduced picture or image and the inadequate frequency response of the television receiver to sudden changes in the brightness or luminance level of the incomming video signal are additive in respect to the degradation of the horizontal sharpness of the reproduced image or picture.
It is well known that an improvement in apparent picture resolution can be achieved by modulating the beam scan velocity in accordance with the derivative of the video signal which controls the beam intensity. This video signal is referred to as the luminance signal and the derivative of the luminance signal is employed for such control. An advantage of this method over a peaking approach to picture sharpness enhancement is the avoidance of blooming of peaked white picture elements.
JVC AV-32WP2EN WIDE SCREEN TELEVISION The invention relates to the field of televisions, for example those televisions having a wide display format ratio screen, which must interpolate video data to implement various display formats. Most televisions today have a format display ratio, horizontal width to vertical height, of 4:3. A wide format display ratio corresponds more closely to the display format ratio of movies, for example 16:9. The invention is applicable to both direct view televisions and projection televisions. Televisions having a format display ratio of 4:3, often referred to as 4 X 3, are limited in the ways that single and multiple video signal sources can be displayed. Television signal transmissions of commercial broadcasters, except for experimental material, are broadcast with a 4 X 3 format display ratio. Many viewers find the 4 X 3 display format less pleasing than the wider format display ratio associated with the movies. Televisions with a wide format display ratio provide not only a more pleasing display, but are capable of displaying wide display format signal sources in a corresponding wide display format. Movies "look" like movies, not cropped or distorted versions thereof. The video source need not be cropped, either when converted from film to video, for example with a telecine device, or by processors in the television.
Televisions with a wide display format ratio are also suited to a wide variety of displays for both conventional and wide display format signals, as well as combinations thereof in multiple picture displays. However, the use of a wide display ratio screen entails numerous problems. Changing the display format ratios of multiple signal sources, developing consistent timing signals from asynchronous but simultaneously displayed sources, switching o between multiple sources to generate multiple picture displays, and providing high resolution pictures from compressed data signals are general categories of such problems. Such problems are solved in a wide screen television according to this invention. A wide screen television according to various inventive arrangements is capable of providing high resolution, single and multiple picture displays, fromsingle and multiple sources having similar or different format ratios, and with selectable display format ratios.
Televisions with a wide display format ratio can be implemented in television systems displaying video signals both at basic or standard horizontal scanning rates and multiples thereof, as well as by both interlaced and noninterlaced scanning. Standard NTSC video signals, for example, are displayed by interlacing the successive fields of each video frame, each field being generated by a raster scanning operation at a basic or standard horizontal scanning rate of approximately 15,734 Hz. The basic scanning rate for video signals is variously referred to as fπ, 1fH, and 1 H. The actual frequency of a 1fH signal will vary according to different video standards. In accordance with efforts to improve the picture quality of television apparatus, systems have been developed for i s displaying video signals progressively, in a noninterlaced fashion. Progressive scanning requires that each displayed frame must be scanned in the same time period allotted for scanning one of the two fields of the interlaced format. Flicker free AA-BB displays require that each field be scanned twice, consecutively. In each case, the horizontal scanning frequency must be twice that of the standard horizontal frequency. The scanning rate for such progressively scanned or flicker free displays is variously referred to as 2fπ and 2H. A 2fH scanning frequency according to standards in the United States, for example, is approximately 31 ,468 Hz.
A wide screen television according to the inventive arrangements taught herein has all of the capabilities and advantages described above. A video display has a first format display ratio, for example 16 X 9. A mapping circuit maps an adjustable picture display are on the video display. First and second signal processors generate first and second selectively interpolated video signals from input video signals having one of different format display ratios, for example 4 X 3 and 16 X 9. The interpolation of the input video signals can result in expansion or compression of the input video signals. The first and second signal processors can also selectively crop the input video signals. Overall, the input video signals can be selectively cropped, interpolated, both cropped and
interpolated and neither cropped nor interpolated. A switching circuit selectively couples video signal sources as the input video signals. A synchronizing circuit synchronizes the first and second signal processors with the mapping circuit. A selecting circuit selects as an output video signal between one of the first and second processed video signals and a combination of the first and second processed video signals. A control circuit controls the mapping circuit, the first and second signal processors and the selecting circuit to adjust in format display ratio and image aspect ratio each picture represented in the output video signal. One of the different format display ratios of the input video signals can be the same as the first format display ratio of the video display. The mapping circuit can comprise a raster generating circuit for a cathode ray tube or an address matrix generator for a liquid crystal display. The display system may further comprise a circuit for converting interlaced video signals to a noninterlaced format, two internal tuners and a plurality of external jacks. In one inventive arrangement, the picture display area is adjustable only vertically and the first and second signal processing circuits interpolate the video signals only horizontally.
This was JVC Flagship in 1998 and was not cheap.
- Attaining optimal sound quality in surround sound or multi-channel sound systems, over the largest possible listening area, can be quite challenging. Some of the difficulties in achieving optimal sound quality in such systems result from the fact that a wide variety of different surround sound and multi-channel audio formats and speaker configurations exist, so that a particular sound system may have reasonably acceptable sound with respect to one or perhaps two audio formats yet sub-optimal sound with respect to other audio formats. Therefore, where a consumer desires, for example, to use a single sound system to play sound recordings in a variety of different formats, different levels of sound quality, some of which are poor or impaired, are likely to be experienced. While the user can adjust speaker positioning or relative balances to try to improve sound quality, such techniques may involve significant manual effort or inconvenience, may be hard to reproduce consistently, and may benefit only one or perhaps a few listeners in a relatively small portion of the listening area.
Ofcourse it has PIP and double tuner feature and large connectivity capabilityies.
Multistandard video decoding and full advanced OSD Menu types toghether with many AND MANY other functions and features are composing 55KG of weight combined by all Advanced Digital signal Processing and a wide screen of 32 Inches (76Cm) plus Hi fi power 3D Sound.
Advanced osd is present for all functions (Inclusive nice Service features.)On screen display (OSD) arrangements employed in video processing systems include a switching (or "multiplexing") network for switching between graphic image representative signals and normal video signals so that a graphic image can be displayed on the screen of a picture reproduction device either in place of the image represented by the video signals or together with (inserted in) the image. The graphic image can take the form of alphanumeric symbols or-pictorial graphics, and can be used to indicate status information, such as channel numbers or time, or operating instructions.
In an OSD arrangement for use in an analog video signal processing system, the multiplexing network typically operates to switch in levels corresponding to the desired intensity of respective portions of the graphic image at the time the graphic image portions are to be displayed. In such an arrangement the graphic image representative signals take the form of timing pulses which occur when the graphic image portions are to be displayed and are used to control the multiplexing network. Such an analog OSD arrangement can also be used in a digital video processing system, but requires that the video signals be first converted to analog form. While digital video signal processing systems typically include a digital-to-analog converter section in which the digital video signals are converted to analog form, it may be more cost effective for the OSD arrangement to be incorporated as an integral part of the digital video processing section.
All of this + picture + sound quality you won't find on modern LCD toys.A SCART Connector (which stands for Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs) is a standard for connecting audio-visual equipment together. The official standard for SCART is CENELEC document number EN 50049-1. SCART is also known as Péritel (especially in France) and Euroconnector but the name SCART will be used exclusively herein. The standard defines a 21-pin connector (herein after a SCART connector) for carrying analog television signals. Various pieces of equipment may be connected by cables having a plug fitting the SCART connectors. Television apparatuses commonly include one or more SCART connectors.Although a SCART connector is bidirectional, the present invention is concerned with the use of a SCART connector as an input connector for receiving signals into a television apparatus. A SCART connector can receive input television signals either in an RGB format in which the red, green and blue signals are received on Pins 15, 11 and 7, respectively, or alternatively in an S-Video format in which the luminance (Y) and chroma (C) signals are received on Pins 20 and 15. As a result of the common usage of Pin 15 in accordance with the SCART standard, a SCART connector cannot receive input television signals in an RGB format and in an S-Video format at the same time.Consequently many commercially available television apparatuses include a separate SCART connectors each dedicated to receive input television signals in one of an RGB format and an S-Video format. This limits the functionality of the SCART connectors. In practical terms, the number of SCART connectors which can be provided on a television apparatus is limited by cost and space considerations. However, different users wish the input a wide range of different combinations of formats of television signals, depending on the equipment they personally own and use. However, the provision of SCART connectors dedicated to input television signals in one of an RGB format and an S-Video format limits the overall connectivity of the television apparatus. Furthermore, for many users the different RGB format and S-Video format are confusing. Some users may not understand or may mistake the format of a television signal being supplied on a given cable from a given piece of equipment. This can result in the supply of input television signals of an inappropriate format for the SCART connector concerned.This kind of connector is todays obsoleted !
Times for such types of sets are gone............. forever.

Victor Company of Japan, Ltd (Nippon Bikutā Kabushiki-gaisha?) (TYO: 6792), usually referred to as JVC, is a Japanese international consumer and professional electronics corporation based in Yokohama, Japan which was founded in 1927. The company is best known for introducing Japan's first televisions, and developing the VHS video recorder.
1920s – 1960s
JVC was founded in 1927 as "The Victor Talking Machine Company of Japan, Limited" as a subsidiary of the United States' leading phonograph and record company, the Victor Talking Machine Company. In 1929 majority ownership was transferred to RCA-Victor. In the 1930s JVC produced phonographs and records, but in 1932 JVC started producing radios, and in 1939 they introduced Japan's first TV. JVC severed relations with its foreign partners during World War II, and was majority owned by Matsushita (Panasonic Corp.) from 1953 to Aug 2007. Finally it became JVC Kenwood Holdings in 2008 after Panasonic (Matsushita) decided to spin off the company and it was merged with Kenwood Electronics.
1970s – 1980s
In 1970, JVC marketed the Videosphere, a modern portable CRT television inside a space helmet shaped casing with an alarm clock at the base. It was a commercial success.
In 1971, JVC introduced the first discrete system for four channel quadraphonic sound sound on vinyl records - CD-4 (Compatible Discrete Four Channel) or Quadradisc, as it was called by RCA in the U.S. In 1976 JVC introduced the 3060, a 3" portable television with an included cassette player.
VC developed the VHS format, and introduced the first VHS recorders to the consumer market in 1977 for the equivalent of US $1060. Sony who had introduced the Betamax home videocassette tape a year earlier, became the main competitor to JVC's VHS into the 1980s creating the videotape format war. The Betamax cassette was smaller with slightly superior quality to the VHS cassette, but this resulted in Betamax having less recording time. By 1984, forty companies utilized the VHS format in comparison with Betamax's twelve. Sony tacitly conceded defeat in 1988 when they also began producing VHS recorders.
In 1979, JVC demonstrated a prototype of their VHD/AHD disc system. This system was capacitance-based like CED, but the discs were grooveless with the stylus being guided by servo signals in the disc surface. The VHD discs were initially handled by the operator and played on a machine that looked like an audio LP turntable, but JVC used caddy housed discs when the system was marketed. Development was interrupted continually, but in April 1983 it was first marketed in Japan, and then in the UK in 1984 to a limited industrial market. By this time both Philips and Sony already had compact discs on the market, and the VHD format never caught on.
In 1981, JVC introduced a line of revolutionary direct drive cassette decks, topped by the DD-9, that provided previously unattainable levels of speed stability.
During the 1980s JVC had a brief appearance in marketing their own portable audio equipment similar to the Sony Walkmans at the time. The JVC CQ-F2K was released in 1982 and had a detachable radio that mounted to the headphones for compact, wire-free listening experience. JVC had difficulty making a success of the products, and a few years later abandoned the product line. In Japan, JVC marketed the products under the name Victor.
In 1986, JVC released the HC-95, a personal computer with a 3.58 MHz Zilog Z80A processor, 64KB RAM and ran MSX Basic 2.0. It included two 3.5" floppy disk drives and conformed to the graphics specification of the MSX-2 standard. However, like the Pioneer PX-7 it also carried a sophisticated hardware interface that handled video superimposition and various interactive video processing features. The JVC HC-95 was first sold in Japan, and then Europe, but sales were disappointing.
JVC video recorders were marketed by Ferguson in the UK, with just cosmetic changes. However Ferguson needed to find another supplier for its camcorders when JVC produced only the VHS-C format, rather than video8. Furthermore, Ferguson was taken over by Thomson SA and so ended the relationship. At the time, JVC had a reputation for reliable, high quality equipment. JVC has gone on to invent hard drive camcorders.
In October 2001, the National Academy of Television Arts and Sciences presented JVC an Emmy Award for "outstanding achievement in technological advancement" for “Pioneering Development of Consumer Camcorders.” Annual sponsorships of the world-renowned JVC Tokyo Video Festival and the JVC Jazz Festival have helped attract the attention of more customers.
JVC has been a worldwide football supporter since 1982, having a former kit sponsorship with Arsenal and continued its role as an official partner of 2002 FIFA World Cup Korea / Japan. JVC made headlines as the first-ever corporate partner of the Kennedy Space Center Visitor Complex. JVC has recently forged elite corporate partnerships with ESPN Zone and with Foxploration. In 2005, JVC joined HANA, the High-Definition Audio-Video Network Alliance to help establish standards in consumer electronics interoperability.
JVC developed the first DVD+RW DL in 2005.
In December 2006, Matsushita entered talks with Kenwood and Cerberus Capital Management to sell its stake in JVC.
In 2007, Victor Company of Japan Ltd confirmed a strategic capital alliance with Kenwood and SPARKX Investment, resulting in Matsushita shareholding being reduced to approx 37%.
In 2008, Matsushita (Panasonic) agreed to spin-off the company and merge with Kenwood Electronics, creating JVC Kenwood Holdings, formed on October 1, 2008.
