ENGINEER FRANK SHARP is gone ........... CRAZY ???????????????
NO because I'm crazy by original development ! ! ! ! :) :) :)
WHY post such thing of crappy plastic tellye at Obsolete Technology Tellye ! ???????????
Answer: Very simple because the SHARP 70GS-61S was technologically spoken the most high integrated digital circuitry developed for a CRT TUBE Television so it's pretty unique for this class of type.
Pictures are awesome powerful, bright and crisp , colors are superb, it's digital but doesn't matter much.
These sets weren't expensive but they were discretely unreliable and very difficult to technologically understand and therefore to repair.
The SHARP 70GS-61S chassis GA-10 It's based on the VCT38XX DIGIT3000 from ITT/MICRONAS technology which was allowing to develop a complete digital television with one chip solution toghether with a one chip for digital audio processing.
Contemporary television processors are complicated and multi-functional. They control the television tuner, video processor, audio processor, deflection parameters, power supply, and video input select.
In a typical television system, television controllers are used. Television controllers receive input from the user and control other units in the television processor. Typically, the television controller is formed on an integrated circuit (IC). Additionally, a video processor is formed on another integrated chip. The video processor converts a video signal to pixel data, which is sent to the display such as a CRT display.
There are disadvantages of having the video processor and the television controller on two different integrated chips. Long wire communication on television chassis with high frequency and sharp signals can cause a lot of electromagnetic interference (EMI) and picture distortions, such as jitter. For this reason, it is desired to have an improved television processor architecture that prevent these problems.
Integrated circuits for use in television are known from, for example, Bolton M: "Empfänger-IC Für Digitales Fernsehen" Blektronik Industrie, vol. 25, no. 8, August 1994 (1994-08), pages 60, 62-63, Hing-Yip Tong: "A single chip micro-computer for A/V Monitor and TV receiver" IEEE Transactions on Consumer Electronics, IEEE Inc.

According to an aspect of the present invention there is provided an integrated circuit including a digital video processor for decoding a video signal and producing a pixel output, a digital television controller for receiving user input and controlling the television channel selection and one or both of an internal interface including registers for exchanging data between the digital video processor and the digital TV controller and a single dot clock generator arranged to receive reference information from the video processor and to produce a dot clock for both the video processor and the television controller.
According to another aspect of the present invention there is provided a method of processing video data comprising providing an integrated circuit including a digital video processor, a digital television controller, decoding a video signal and producing a pixel output in the digital video processor and receiving user input and controlling television channel selection in the digital television controller. The method further comprising one or both of further providing an internal interface including registers and exchanging data between the digital video processor and the digital television controller by storing the data in the registers and further providing a dot clock generator and producing a single dot clock in the dot clock generator from reference information supplied by the video processor, the dot clock being supplied to both the video processor and the television controller.
By putting the television controller and the video processor together on one integrated circuit chip, the length of the communication links between these two elements is reduced. This can remove some of the problems of the prior art. Additionally, by using a single dot clock generator for both the video processor and the television controller, the picture quality can be improved. Prior systems had a dot clock generator with its own phase locked loop (PLL) circuit on both the video processor IC and the television controller IC. It is impractical to send the clock signal between integrated circuits so each IC would reconstruct a dot clock from the horizontal and vertical sync. Since the television controller and the video processor can be synchronized by a single dot clock in the present system, this facilitates features such as picture-in-picture (PIP) and on-screen display (OSD).

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.
