The MIVAR 21MF51 STEREO is a 21 inches (51cm) color television with real flat screen.
Was first MIVAR TV set with a real flat CRT Screen and small 21 format for that !
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 permanent 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.
It has 50 programs PLL synthesized tuning, it's multistandard and has digital stereo sound with bilingual and tone control feature and teletext.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.
It features a simple OSD and has 2 AV SCART Sockets, frontly there is a stereo headphone jack and manual controls and further AV RCA connections availability.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.
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.This kind of connector is todays obsoleted !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.
The set is first and last MIVAR model series featuring a small screen format with real flat screen type, after that they dropped quickly crt production to start assembled lcd tvs.
The set here shown have had a very small time of use and if even can't be considered a vintage is anyway highly better than any lcd shit lying around.
(The set is a year 2005 made so it's not that old but since was undeservedly thrown away in perfect shape and working order I've rescued it and now it's (happy) sitting here at Obsolete Technology Tellye museum and getting, after some test time, the ......... dust on it !! )
It's made by MIVAR an Italian Brand NO MORE ACTIVE In television manufacturing.
MIVAR Sets have had great features and extreme simplicity toghether with compactness and combined with reliability and durability.
(Basically all what today you won't see anymore !)
A brief note about on Television sets reliability and durability..........................
ANYONE
with even the smallest experience of television engineering is bound to
come up against that embarrassing question which is always so difficult
to answer-"which TV shall I get?" The questioner is usually concerned
about obtaining the cheapest and most reliable receiver that is
available, and this same approach generally governs the choice between
buying when new - restoring in this time. This is perfectly reasonable and often applies to
other consumer products apart from TV.
What does seem a little strange
however is that no one ever seems to ask "which TV set gives the best
picture?" Why not? Doesn't anyone care, or is the question too
complicated to discuss?
Yet the average person spends five and a half
hours a day, every day, watching TV garbage:
The Propaganda TV Machine a.k.a. The Ministry of Truth delivers The Truth from The Government to the people.
At least, that's what they say. In fact, a Propaganda Machine is only employed by The Empire and used to brainwash people into Gullible Lemmings who believe that everything is all right when in fact, it isn't, and that the very people who could help them are their enemies..............
At least, that's what they say. In fact, a Propaganda Machine is only employed by The Empire and used to brainwash people into Gullible Lemmings who believe that everything is all right when in fact, it isn't, and that the very people who could help them are their enemies..............
................... so the quality of the picture must
be important........................
expecially
for those football idiots so the they have the motivation to glue their
assface on the screen all day long to discover better somewaht in their
ignorance.
........Now................It
is high time that people began to realise this simple fact, and to take
an interest in the quality of the product that absorbs so much of their
spare time. There are of course plenty of people who are genuinely
interested in good picture quality. It is unlikely for example that so
many readers of this Blog would be taking part in the magnificent TELEVISION colour receiver project,
but more likely restoring monochrome receivers or adapting old color
ones, if they were
indifferent to the quality of the picture obtained at the end of the
day. But today times seems changing, the trend started by many readers
of Obsolete Technology Tellye ! have had a significative rise up in
recovering and restoring old CRT's TV's and started to build up
collections by people in many lands worldwide.
Good CRT picture quality cannot however be achieved merely by
connecting together the appropriate groups of circuits. Sometimes in
fact even well established designs can present problems if they are
assembled in a different way to the original or with non-standard
components.
So what constitutes good picture quality and what do you do
when things go wrong?
It is not much use delving into the textbooks
because they are strangely unhelpful about this sort of thing.
At least
however we can here at Obsolete Technology Tellye ! establish some
basic principles to use as a starting point. There is a difference
between the kind of picture quality defects that you would expect to
find in a manufactured receiver compared to one made by a home restorer /
constructor.
A CRT manufactured receiver usually has only minor faults
and one wants to'assess how well it compares with the products of other
set - makers.
Todays trade, threw a rather different light on matters
however. Briefly, we found that during CRT boom periods for the
setmakers reliability increased whilst during periods of diminishing
sales a fall in the standard of reliability became evident, so you will find excellent sets from the 70s/80s. I had
tended to think that a boom meant an attitude of anything goes to get as
many sets out to meet the demand, with consequent corner cutting and
use of whatever alternative components could be got hold of if
necessary. The overriding point seems to be however that in boom
conditions with a seller's market prices can be maintained and quality
standards kept up whilst in flat market conditions there is overwhelming
pressure on prices and reliability tends to fall. It is difficult to be
too sure about this since the worst trading period coincided with the
era of dual standard analog TV sets which may eventually but not certainly inevitably less
reliable than the single -standard chassis which preceeded and succeeded
them. It would however tie up about the comparative reliability of
colour and monochrome sets, since the era of colour boom coincides with a
very flat period in monochrome set production and sales, that in
talking about reliability means overall dependability rather than
initial statistics for unboxed set condition.
That all said is very
applicable to todays times, with completely different technically means, reality where
unfair market conditions focibly applied to European firms by an elite which has
only the will and target to destroy European eritage at all
levels with the main point in destroying local economy.
It includes:
- A number of areas of law involving acts by one
competitor or group of competitors which harm another in the field, and
which may give rise to criminal offenses and civil causes of
action.
- Trade libel, the spreading of false information about the quality
or characteristics of a competitor's products, is prohibited at common
law but still high present and unstopped.
- Various unfair business
practices such as fraud, misrepresentation, and unconscionable contracts
may be considered unfair competition, if they give one competitor an
advantage over others expecially all from the so called ASIATIC MARKET.
Therefore:
All of todays apparates are literally absolute GARBAGE when new and resulting often broken when out of the box after purchase. Poor engineering, manufacturing and materials in the main part, combined with unfair massive import to Europe of such DUMP goods, at cheap prices in closed hard tight market (so they can be the only 2 3 competitor in foreign lands and all locals firms brought to death by heavy taxations, troublesome difficulties at all levels) and sold with medium to high prices respect to initial build costs !!
For that there can't be a comparation of reliability between a CRT TV SET and any one of todays sets, which often are resulting in a SCAM mainly under the technological part, emerging, even, from the first repair attempt !
...... And in the end you will NEVER SEE a restoring of ANY of the Actual todays electronic GARBAGE !
R.I.P. EUROPE !
It's made by MIVAR an Italian Brand no more active since 20/12/2013.
MIVAR is a Factory site in the near of Milan (italy) in a Industrial city conglomerate called Abbiate Grasso.
Founded in 1945 by Mr. Carlo Vichi class of 1923, The activity started in 1945 - in Milano, Via Ugo Tommei 5 street with fab
rication of little radio apparates.
HISTORY OF MIVAR.
1945 - Milan, Via Ugo Tommei 5: Begin the activity assembling small radios.
1950 - Via Curtatone 12: developed with the construction of more direct major radio components fabricants.
1956 - 13 Street Strigelli: industrial production is manily targeted to first radio devices with frequency modulation (FM).
1958 - Via P. 30 Jordanians: TV become a reality, the industries is doubling his ACTIVITY, always in Milan, we build the first "real" plant with 400 employees.
1963 - Abbiategrasso, Via Dante 45: in the wake of decentralization and the rampant success of the television, building a facility that will become important in place 800 employees occupying between 1968-70.
1990 - Abbiategrasso Canal towpath: aware of the physiological importance that television plays in society? Modern, rich expertise and resources, we began construction of a factory area of 120,000 m? which covered 30.00o , for the viabilit with parking spaces and 60,000 park trees.
In origin the factory was brand named as Radio Var and indeed the tellye here in collection is internally marked as Radio VAR. After 1985 they were marked rightly MIVAR.1945 - Milan, Via Ugo Tommei 5: Begin the activity assembling small radios.

Today's activity is oriented in virtual production of LCD crap but with very low market penetration due to "unfair" asian competitors presence and a local governement which don't care about.
(You call it global market, I call it WORLD DESTRUCTION combined toghether with mass Afro scum crap Immigration (EUROPEAN INVASION) to obtain destruction on a large scale in all places and to help more and better the loose of all OUR workplaces and firms , lives, people).
“If our buildings, our highways, and our railroads should be wrecked, we could rebuild them.
If our cities should be destroyed, out of the very ruins we could erect newer and greater ones.
Even if our armed might should be crushed, we could rear sons who would redeem our power.
Anyway Obsolete Technology Tellye will show even this model as a Time machine which looses nothing of the good tellyes ! ! !

R.I.P CARLO !
(Montieri, 5 febbraio 1923 – Milano, 20 settembre 2021).
Hi Frank, I still have a Mivar 14p and now I live in Ireland. Do you also know how I can make it work here with the UK frequency? I can see clear images but audio is pretty much disturbed. The TV is new, used really few and it'd be a shame getting rid of it just because of that. Thanks in advance!

ReplyDeleteHi, BlackLily.
Assuming that the set is in prefect working order without obscure already present fault conditions:
Question: How do you feed the Audio and Video signals ??
1-Via AV SCART socket ? or
2-Via RF standard broadcast (classical antenna input) ??
If the case is the "1" change your DVB decoder output feature accordingly to PAL-BG standard configuration or , if present, south European CCIR standard. This because the set is initially configured and developed for Italian Broadcasting norms and therefore this should do the trick.
If the case is the "2" then no solution is available because of the different standard of broadcast transmissions and configuration of the TV IF detector, , which this can be changed and configured only via Service configuration menu but is beyond user possibility, trying it without proper knowledge may cause to mess things up and landing to partly or total unusability of the set.
(Yes they have superb pictures)
Have fun,
FRANK.
