NORDMENDE (THOMSON) CONTURA 63 (ICC9) YEAR 1993.









 The NORDMENDE (THOMSON) CONTURA 63  is a 25 inches color television with planar square screen, black matrix.

The set features mutistandard feature, stereo hifi sound, teletext, CTI, LTI, SVHS, 2 AV SCART sockets, external loudpseakers jacks, headphone jack, osd...............

The Teletext is a television-based communication technique in which a given horizontal video line is utilized for broadcasting textual and graphical information encoded in a digital binary representation. Such horizontal video line signal that contains teletext data is referred to herein as a Data-line. It is assumed herein, for explanation purposes, that teletext is sent by the broadcaster only during the vertical blanking interval (VBI), when no other picture information is sent. The organization of the binary information in the broadcast signal is determined by the standard employed by the broadcaster. By way of an example only, references are made herein to a teletext based on a standard referred to by the British Broadcasting Corporation (BBC) as CEEFAX.

Each Data-line carries data synchronizing and address information and the codes for a Row of 40 characters. The synchronizing information includes a clock run-in sequence followed by an 8-bit framing code sequence. Each Data-line contains a 3 bit code referred to as the Magazine number. A teletext Page includes 24 Rows of 40 characters, including a special top Row called the Page-Header. Each ROW is contained in a corresponding Data-line. A user selected Page is intended to be displayed in place of, or added to a corresponding television picture frame. A Magazine is defined to include Pages having Data-lines containing a corresponding Magazine number. The transmission of a selected Page begins with, and includes its Page Header and ends with and excludes the next Page Header of the selected Magazine number. All intermediate Data lines carrying the selected Magazine number relate to the selected Page.
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 !

The set was first tv set from THOMSON featuring the sophisticated chassis ICC9 wich was pretty unique and special by design and technology and  complications THOMSON STYLE.


And was first set introducing the picture signal improvement. A method of picture signal improvement in accordance with a first aspect of the invention, an input picture signal is filtered to obtain a high-frequency component and a low-frequency component, a standard deviation signal is calculated from the input picture signal, the high-frequency component is gain controlled in dependence upon the standard deviation signal to obtain a gain-controlled high-frequency component, and the gain-controlled high-frequency component and the low-frequency component are combined to obtain an output signal.
Prior means for improving the edge transitions of video signals include the addition of an enhancement or peaking signal to the original video signal. These enhancement or peaking signals are normally generated through such techniques as taking the first or second derivative of the original video signal, and adding the derivative signal, in an appropriate amount and polarity, to the original video signal. Another technique is to use a transversal filter, such as a tapped delay line; wherein, input, output and tap signals are suitably weighted, signed and combined to produce a "peaked" output signal. Still another technique is use a delay line that is unterminated on its output but terminated on its input. By subtracting the output signal from the input signal, a "peaking" signal is produced that is added in an appropriate amount and polarity to the output signal.
 In order for these methods to achieve significant improvement in the resulting signals rise and fall times of edge transitions, a relatively large amount of enhancement or "peaking" signal must be added to the original video signal. However, this also produces excessive preshoots and overshoots at the edge transitions. In a television system, the white going preshoots and overshoots can cause spot blooming on the CRT display. It is an object of the present invention to furnish apparatus for sharpening the edges, i.e. decreasing the transition times from a dark to a light level and vice versa in a received video signal in which such changes take place at varying rates, without adding preshoots or overshoots to the resultant signal.

It is a further object of the present invention to carry out this objective with a minimum of additional circuitry in a reliable fashion.

According to the present invention, the first and second derivatives of the incoming signal are generated, and the so generated derivatives are multiplied to each other to generate a control signal.

The incoming signal is also subjected to a first and second time delay. A switching circuit operative under control of the control signal normally connects the signal at the output of the first time delay to the circuit output. In response to the control signal, the circuit output is first connected to the output of the second time delay, next to the signal directly as received and finally back to the signal at the output of the first time delay.

The second time delay exceeds the first time delay and, preferably, is equal to twice the first time delay. The sharpening of the edges thus occurs because the transition is delayed until th directly received video signal has completed the transition. At this point the signal output is switched to the direct input, causing a sharp transition. After the final value of the transition has been stabilized, the signal output is switched back to the output of the first time delay where it remains until the next subsequent transition takes place.

In a preferred embodiment of the invention, the control signal is derived by multiplying the first and second derivatives of the incoming signal to each other and amplitude limiting the resulting signal.

Introduces even the CTI feature for the sharpening of colour transitions. 
In the past analog commercial TV transmission standards, the limited bandwidth of the transmitted chrominance (or chrominance difference) signals causes the received images to have perceptibly blurred colour transition edges. This is especially evident if the received image contains geometrical patterns, e.g. test-colour bars, and results in the loss of detail detectable in complex multicoloured fine patterns.

In order to improve the quality of the received images, it is necessary to provide the receiver end with circuits capable of restoring, as far as possible, the frequency components in the chrominance signals which have been filtered away by the requirements of the reduced transmission bandwidth: in this way, the temporal duration of the chrominance transition edges, and thus the spatial extent of the chrominance transitions on the TV screen, can be reduced, and the edge definition improved. Circuits of this type are called "Color Transient Improvement" ("CTI") or Chrominance Transition Enhancement circuits.

An important constraint on chrominance transition enhancement circuits is the need to ensure that the center of the chrominance transition is unaffected by the enhancement process, so that the center of the chrominance transition after the enhancement process is still aligned with the center of the associated transition in the luminance signal. Also, it is necessary to leave gradual transitions in time unaltered; preserve, and possibly enhance, fine patterns; prevent the introduction in the image of additional distortions; and ensure that the existing noise components are not accentuated.
The set has superb pictures with very precise picture contour and crisp colors thankfully to special Signal processings.

The set is last series with PLANAR CRT tube after that was abandoned definitely.

 The VIDEOCOLOR PLANAR featured has even an improvement for increased EHT to obtain more focussing.One aspect of the present invention is concerned with reducing the size of the crossover, and thus of the image thereof on the screen, compared with the known gun. In accordance with this aspect of the invention, the voltage applied to the first anode is higher than in a corresponding conventional gun and in particular is greater than the voltage applied to the focussing anode. As a result, a high electric field is formed between the grid and the first anode which tends to reduce the size of the crossover, aspect of the invention seeks to utilise this high voltage in controlling the beam size.

Nordmende was a manufacturer of entertainment electronics based in Bremen, Germany.
The original company, Radio H. Mende & Co, was founded in 1923 by Otto Hermann Mende (1885-1940) in Dresden. Following the destruction of the plant during the bombing raids in 1945, Martin Mende (the founder's son) created a new company in Bremen in 1947, in a former Focke-Wulf plant, under the name North German Mende Broadcast GmbH. The name was subsequently changed to Nordmende: subsequently the company became one of the prominent German manufacturers of radios, televisions, tape recorders and record players in the 1950s and 1960s.
In the 1970s, Nordmende televisions were renowned for their innovative chassis, and for the rigorous testing and quality control of their finished products. Both created high costs, however, which soon proved a competitive disadvantage when the price of colour televisions began to plunge.
In 1969, Mende's sons took over the company, and in 1977 a majority shareholding was sold to the French Thomson Brandt company and the chassis remains the original NordMende until CHASSIS F9. The following year, the family sold their remaining shares to Thomson. In the 1980s, the factories in Bremen were closed, Nordmende becoming purely a Thomson trademark (Starting from chassis F10 F11 they're all THOMSON).








In the 1990s, the name Nordmende was used with decreasing frequency, and it eventually disappeared in favour of the Thomson name. In 2005 Videocon Group acquired all cathode ray tube activities from Thomson. This led to the creation of VDC Technologies, which manufactures TV sets using the Nordmende brand under licence from Thomson.
The Nordmende brand name was relaunched in Ireland in September 2008 by the KAL Group. Although Nordmende was well known for its televisions throughout Ireland during the 1970s and 1980s, the company bought the rights to the name and launched a range of white goods including fridges, freezers, washing machines, and dishwashers, alongside a revamped range of flat-screen TVs and stereos.



     
NORDMENDE HISTORY IN GERMAN:

Die Vorkriegsgeschichte findet sich unter Mende. Nach dem Totalverlust in Dresden gründet Martin Mende (30.12.1898-1982) unter Mitwirkung von Hermann Weber am 26. August 1947 [FT5901] in Bremen-Hemelingen die Norddeutsche Mende-Rundfunk GmbH.

Die ersten Gehäuse liefert ein Tischler in Achim gegen Kompensation von fünf Gehäusen zu einem Rundfunkgerät. Der frühere Mende-Konstrukteur, Obering. Heer zeichnet wieder für die Geräte verantwortlich [FT49??].

Ab 27. Juli 1948 liefert die neue, zuerst 18 und bald 60 Personen umfassende Firma auf Grund von Währungsreform, Krediten und Zulieferverträgen die neue Radioproduktion.

Das Regime in Ostdeutschland lässt den Namen Mende nicht zu, so dass Martin Mende mit grafischen Konstruktionen im Zusammenhang mit «Nord» an seinen Vorkriegserfolg anschliesst.

Die Hallen der ehemaligen Focke-Wulf AG beim Bahnhof Seebaldsbrück dienen als Werkstätten. 1950 beschäftigt das Unternehmen 700, 1959 schon 3500 und im Zenit 6300 Personen.

1950 beginnt die Firma mit UKW-, 1953 mit Fernseh- und 1954 mit Mess- und Prüfgeräten. Gegen Ende der 50er Jahre heisst die Firma Norddeutsche Mende Rundfunk KG [RP7901].

Nachdem sich Nordmende bislang nicht mit Magnettongeräten befasst hat, bringt das Werk 1958 das erste deutsche Heim-Tonbandgerät mit drei Motoren auf den Markt. Allerdings dominieren auf diesem Sektor eindeutig andere Firmen wie AEG/Telefunken und Grundig. Von Nordmende kommen jeweils nur ein bis zwei Geräte (1960 keines) in die Kataloge. Dafür hat die Firma Erfolg mit einem anderen Neueinstieg:


1958 stellt Nordmende mit «Mambo» ihr erstes Reisegerät vor - aber nicht «das erste deutsche, serienmässig hergestellte und volltransistorisierte Koffergerät», wie man aus einer Quelle nachlesen kann. Danach wird Nordmende in Deutschland auf dem Sektor Reisegeräte besonders stark, obwohl sie keine Röhren-Koffer baute. Immerhin kosten die in «Mambo» verwendeten 8 Halbleiter dann im Einzelhandel DM 98.70, während für die vier D-Röhren der 90er-Serie - auch zum Katalogpreis - etwa DM 35.- auszugeben wären. Preis des ganzen Gerätes: DM 189.- plus zwei Flachbatterien von 4,5 V.

Bis 1969 gibt es ca. 92 Modelle der tragbaren Radios (Koffer- bzw. «Handradios», d.h. «Hand held radios»). Beispielsweise finden sich im Katalog 1961/62 [448] je 11 Tischradios und Radiomöbel sowie 8 Modelle von Reiseradios. 17 verschiedene Fernsehmodelle zeigen dagegen, wo in jener Zeit der Erfolg zu holen war.

Gemäss [FT7901] liegt Nordmende während kurzer Zeit mit der sogenannten «Tippomatik-Bedienung» sogar technisch vorne. Siehe auch Philips etc.

Auch Konzertschränke scheinen Ende der 50er bis Anfang 60er Jahre eine tragende Säule für Nordmende zu sein. Dabei verwendet die Firma immer wieder gleiche Namen wie «Cabinet», «Caruso», «Casino», «Cosima» sowie «Arabella» und «Isobella» mit wechselnden Zusatz-Nummern oder den Zusatz «Stereo», z.B. in den Jahren 1959 und 1960/61.

Im März 1967 nimmt das Werk die Produktion von Farbfernsehgeräten auf. Zum Firmenjubiläum erscheint eine Gerätereihe mit der Bezeichnung 'Goldene 20'. 1969 übernehmen die Mende-Söhne Karl und Hermann die Geschäftsführung.

1977 führt der verschärfte Wettbewerb zum Verkauf der Mehrheit an den französischen Konzern Thomson-Brandt; die Familie Mende zieht sich anschliessend ganz aus dem Unternehmen zurück. Martin Mende stirbt 1982.


In 1879 Elihu Thomson and Edwin Houston formed the Thomson-Houston Electric Company in the United States.

On April 15, 1892 Thomson-Houston and the Edison General Electric Company merged to form General Electric (GE). Also in 1892 the company formed a French subsidiary, Thomson Houston International.
In 1893 Compagnie Française Thomson-Houston (CFTH) was set up as a partner to GE. It is from this company that the modern Thomson companies would evolve.
In 1966 CFTH merged with Hotchkiss-Brandt to form Thomson-Houston-Hotchkiss-Brandt (soon renamed Thomson-Brandt). In 1968 the electronics business of Thomson-Brandt merged with Compagnie Générale de Télégraphie Sans Fil (CSF) to form Thomson-CSF. Thomson Brandt maintained a significant shareholding in this company (approximately 40%).
In 1982 both Thomson-Brandt and Thomson-CSF were nationalized by François Mitterrand. Thomson-Brandt was renamed Thomson SA (Société Anonyme) and merged with Thomson-CSF.
From 1983 to 1987 a major reorganisation of Thomson-CSF was undertaken, with divestitures to refocus the group on its core activities (electronics and defence). Thomson-CSF Téléphone and the medical division were sold to Alcatel and GE respectively. The semiconductor businesses of Thomson CSF was merged with Finmeccanica. Thomson acquired General Electric’s RCA and GE consumer electronics business in 1987.
In 1988 Thomson Consumer Electronics was formed, renamed Thomson Multimedia in 1995. The French government split the consumer electronics and defence businesses prior to privatisation in 1999, those companies being Thomson Multimedia (today Technicolor SA) and Thomson-CSF (today Thales Group).



Thomson-CSF was a major electronics and defence contractor. In December 2000 it was renamed Thales Group.


...........1996............there are no stranger foreigners than the first ones you come across, the French. This is borne out by the 1996 Thomson situation. Thomson, was a vast company by any reckoning, is a strange beast. It's state controlled, which means that the government owns most but not quite all of it. and consists of two distinct arms, the defence group Thomson-CFS which is quite profitable, and the consumer electronics group Thomson Multimedia which loses a packet. The government wanted  rid of it, but won't sell the bits separately. It doesn't want to be left with the problem of what to do with Thomson Multimedia. You might think that no one would be interested in helping the French government. But in fact there are two contenders to take over Thomson, the telecommunications and power group Alcatel Alsthom and the defence and media group Lagardere. They have been engaging in quite a battle over the ownership, and as we go to press the French government is due to decide whose bid to accept. Whoever wins will end up with the profitable defence company  and the problem of Thomson Multimedia (TMM).

Lagardere has stated that it would sell TMM to Daewoo of Korea. Alcatel Alsthom has not been quite so specific, but has announced that it would take immediate action to reduce TMM's losses and seek an "Asian partner" that "specialises in consumer electronics". The partner would be expected to take over management of TMM, but Alcatel would like to remain a "minority partner" - it sees prospects in the move to digital TV technology that will occur during the next decade. All this gives one a strange feeling of déjà vu. At the time when Thomson took over Ferguson, in June 1987, it was noticed  that Thomson is "now on the government's privatisation list". It's taken almost a decade to happen.

 It's also said that "Thomson may be big, but has not been all that successful in the past in the consumer electronics field". Right on! What has happened to Ferguson in the UK illustrates the dismal Thomson effect. From being the local brand leader, with over ten per cent of the market, Ferguson has ended up being an also ran. It's only fair however to mention that Ferguson was making substantial losses when Thorn EMI was glad to get £90m for it from Thomson. Thomson has been able to survive in the consumer electronics field because it is part of a larger organisation, with those defence profits. It has nevertheless over the years attempted to play a a major role in the international consumer electronics field, keeping up with Philips and the Japanese corporations. From its French origins, it first expanded by picking up various German companies such as NordMende an SABA. It added Telefunken, a venerable name if ever there was one in this industry, in the early eighties, then took what was to be a big move into the UK market when it bought Ferguson. 

It  used six brand names in Europe. The largest step however occurred when TMM became a major force in the North American market by taking over General Electric's consumer electronics interests. This also gave it the RCA operation. The idea behind all this seems to have been to achieve success simply by getting bigger. There was always government finance to back the policy, which in the event has not been a success. The TMM debacle is a sad one, since Thomson's research and engineering has had many successes.
 It has not stinted on R and D work, with laboratories in Los Angeles, Indianapolis, Strasbourg, Hanover, Villingen, Tokyo and Singapore. Much work has been done on HD -TV, digital signal processing and other developments that have kept it in the forefront of the technology. Now, it seems, TMM is likely to be swallowed up by one of the Oriental corporate giants. 
If there are any lessons to be drawn, they would seem to be that expansion by itself is no guarantee of success, that to spread ones activities and their control across the globe makes management extremely difficult, and that costs are very hard to control in such a context. Alcatel Alsthom's plans to reduce TMM's losses bear this out. It would close down TMM's US factories, transferring production to the company's modern facilities in Mexico, where wages are much lower.

 It would rationalise the large collection of brands, possibly adopting RCA as the main one worldwide. And there is a suggestion that the company should be run from the USA, since this is its largest market. But all this would be just initial steps towards ceding majority control. Venerable brand names such as Telefunken, GE and RCA would pass to oriental ownership. This will happen whoever wins, Alcatel Alsthom or Lagardere, which would leave just Philips to carry on Europe's traditions in the consumer electronics field............. but we all know how it ended.................

Thomson-CSF independence

Following the privatisation of the Thomson Group Thomson-CSF explored the possibility of merging with Marconi Electronic Systems, however British Aerospace was successful in that aim, forming BAE Systems.
In 2000 Thomson-CSF went through a series of transactions, including with Marconi plc. The major acquisition at this time was the £1.3 billion purchase of the British defence electronics firm, Racal. This made Thomson-CSF the second largest participant in the UK defence industry after BAE. Racal was renamed Thomson-CSF Racal plc.
On December 6, 2000 the group was renamed Thales.
