The MIVAR 25M4 is a 25 inches (59cm) color television with 50 programs 100 channels PLL synthesized tuning, OSD, and dual speaker sound system.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.
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.
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.
The MIVAR 25M4 is first MIVAR color TV series featuring the PHILIPS TDA8843 I2C-bus controlled PAL/NTSC/SECAM TV processor: giving the interesting chassis design in only 2 chip fashion, even further adding better picture processing enhancement.Through the use of solid state electronics, printed and integrated circuit art, and similar modern technical advances, television manufacturers have been able to greatly reduce the constructional complexity of the standard color television receiver chassis and to increase the number of instrumentalities that are mountable thereon until only the picture tube and a few relatively bulky parts remain separately mounted. This simplification of construction reduces the cost of initial manufacture, improves the service and repair of the receiver, and enhances the acceptability of the receiver to the consumer by meeting consumer demands for reducing the cost of maintenance and for providing an electronic chassis lending itself to home repair.The M4 from MIVAR Tv series was an example of that.
It has also 2 AV SCART Sockets, Teletext, and headphones jack.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.
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 cabinet is made of a high quality plastic which doesn't know age or degradation at all.
The set features a TCT (ECIMEX GROUP) CRT tube (Picture wasn't great) with blackStripe frit mask which technology have had the purpose to prevent any quality reduction of a shadow mask screen by preventing any clear boundary of a frit glass layer from geing formed by placing a shield facing the area of the shadow mask on which the frit glass layer is not formed and making a liquid frit glass suspension to flow toward said area.It was invented by TOSHIBA In 1986.

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 !)
MIVAR is a Factory site in the near of Milan (italy) in a Industrial city conglomerate called Abbiate Grasso.
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.
Today's activity is oriented in virtual production of LCD crap (ceased) 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 to obtain destruction on a large scale in all places and to help more and better the loose of all OUR workplaces and firms).
Anyway Obsolete Technology Tellye will show even this model as a Time machine which looses nothing of the good tellyes ! ! !
