The SHARP 54DT-25S is a 21 inches (51cm) color television with 50 programs VST tuning search system and OSD.
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.
Features a PHILIPS Black matrix CRT Tube and it has a AV SCART socket and teletext feature.
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 SHARP 54DT-25S was the response against the upcoming of the market dump behaviour of very cheap television sets from extra European firms (beko).
The set wasn't cheap but was mass marketed to offer some different price product in a clear sinking economy aspect.
In economics, "dumping" is a kind of predatory pricing, especially in the context of international trade. It occurs when manufacturers export a product to another country at a price either below the price charged in its home market, or in quantities that cannot be explained through normal market competition.
A standard technical definition of dumping is the act of charging a lower price for the like goods in a foreign market than one charges for the same good in a domestic market for consumption in the home market of the exporter. This is often referred to as selling at less than "normal value" on the same level of trade in the ordinary course of trade. Under the World Trade Organization (WTO) Agreement, dumping is condemned (but is not prohibited) if it causes or threatens to cause material injury to a domestic industry in the importing country.
The set is an example of how to realize a complicated TV chassis even with only a 2 chip design, shows the mental disease of some engineers, same as the SHARP GA-10 CHASSIS DESIGN.
Was first Sharp television featuring the PHILIPS TDA8840, IS A I2C-bus controlled single chip TV processors which IS intended to be applied in PAL, NTSC, PAL/NTSC and multi-standard television receivers.
Sharp Corporation ( Shāpu Kabushiki-gaisha) is a Japanese multinational corporation that designs and manufactures electronic products. Headquartered in Abeno-ku, Osaka, Japan, Sharp employs more than 55,580 people worldwide as of June 2011. The company was founded in September 1912. It takes its name from one of its founder's first inventions, the Ever-Sharp mechanical pencil, which was invented by Tokuji Hayakawa (早川 徳次) in 1915. Since then it has developed into one of the leading electronics companies in the world. It gained greater public awareness in the United Kingdom when it sponsored Manchester United F.C. from 1982 to 2000, which was a period of great success for the club.
Sharp took a controlling stake in Pioneer Corporation in 2007. On 25 June 2009, they agreed to form a joint venture with Pioneer on their optical business to be called "Pioneer Digital Design and Manufacturing Corporation".
HistoryIn 1912, Tokuji Hayakawa (早川 徳次) founded a metal workshop in Tokyo. The first of his many inventions was a snap buckle named 'Tokubijo'. Another of his major inventions was the Ever-Sharp mechanical pencil in 1915, from which the Sharp Corporation took its name.] After the pencil business was destroyed by the 1923 Great Kantō earthquake, the company relocated to Osaka and began designing the first generation of Japanese radio sets. These went on sale in 1925. In 1953 Sharp started producing television sets.
In 1964 Sharp developed the world's first transistor calculator, which was priced at Yen 535,000 (US$1,400). It took Sharp several years to develop the product as they had no experience in making computing devices at the time. Two years later, in 1966 Sharp introduced its first IC calculator using 145 Mitsubishi-made bipolar ICs, priced at Yen 350,000 (about US$1000). Its first LSI calculator was introduced in 1969. This was the first pocketable calculator priced at less than Yen 100,000 (less than US$300), and turned out to be a bestseller.
Other notable achievements include the first LCD calculator in 1973. LCD technology continues to be a key part of Sharp's product range, in both the component and consumer-appliance sides of the business. Sharp shared a close working relationship with Nintendo during the 1980s, and was granted licensing rights for the manufacture and development of the C1 NES TV (1983, later released in North America as the Sharp Nintendo Television), the Twin Famicom (1986), the Sharp Famicom Titler (1989), and the SF-1 SNES TV (1990). All of these units are considered collectors items on the secondary market.
Sharp's Mobile Communications Division created the world's first commercial camera phone, the J-SH04, in Japan in 1997. In 2008 Sharp collaborated with Emblaze Mobile on the Monolith, "...an ambitious project to design the ultimate holistic mobile device".
Shaping the future with innovations – this has been Sharp's motto ever since it was founded in 1912. Like almost no other company, Sharp has made major contributions to technological development.
Sharp's roots date back to the year 1912. On 15 th September 1912, Mr Tokuji Hayakawa establishes a small metalworking shop in Tokyo . At that time already, innovations are a major key to success. Sharp's founder is granted his first patent at the age of 18 – for the "Tokubijo", a belt buckle. The business starts with 3 employees and a capital of a mere 50 yen.
GrowthThrough innovative products and a solid business strategy, the small business expands continuously. In 1915 Mr Hayakawa invents the world's first mechanical retractable pencil – the “Ever Sharp Pencil”. The company's name is derived from this invention and the "Ever Sharp Pencil" stands for Sharp as a symbol of innovative power and pioneering spirit.
Sharp introduces "Quattron Technology" on their LE820 Series. As first in the industry, Sharp’s leading-edge liquid crystal technology has produced the revolutionary Quattron panel. It employs a four-colour filter that adds yellow (Y) to the three primary colours of red, green and blue (RGB), expanding the colour gamut and faithfully rendering nearly all colours that can be discerned with the unaided human eye, especially golden yellow. Combined with Sharp’s X-Gen panel that applies UV2A technology, the displays deliver an unprecedented high-quality picture as well as reduce energy consumption with an LED backlight.
