Fundamental aim of Television is to extend the sense of sight beyond its natural limits, along with associated sound. It is radio communication of sound along with picture details. The picture signal is amplitude modulated sound signal frequency modulated before transmission. Carrier frequencies are suitably spaced so that combined signal can be radiated through a common antenna. Each broadcasting station can have its own carrier frequency and receiver can be tuned to select desired stations by tuning to respective frequency...
Main constraint for colour TV was compatibility with existing monochrome system. It should produce normal black and white picture on monochrome receiver without any modification on receiver circuitry. Moreover colour receiver must produce a black and white picture if transmission is monochrome.
Hence it should have same - bandwidth, location & spacing of sound and video frequencies, luminance information as a monochromatic signal. Colour information in signal should not effect picture on a monochrome receiver. Other circuit details of colour receiver should be same as that of monochromatic receiver..
PRESENTATION ON EVOLUTION OF TELEVISION AND THE PATENTS RELATED TO ITS EVOLUTIONPOOJA
The presentation contains the history related to television and major milestones which lead to the creation of television that we are able to see now.All the major patents list have also been mentioned in the presentation.
The 20th Century was the century of broadcasting. In this century we as films, books, TV, long play records, cassettes, CDs, DVD etc. The all had few things in common: they were one-way medium, a broadcast from one to many. Producers were limited and became gatekeepers of content. Somebody selected the films to show in theaters, movies to watch on TV etc. The 20th century was the time of movie stars and pop stars.
It turns out all these mediums have one other thing in common: they are based on a model of scarcity, i.e. program directors have to choose the program for you, since there are only finite number of channels and screens. There are only finite space of shelfs for CDs in store. So we needed pop starts. The many consumers had to listen to the same few albums.
With the Internet in the 21st century this model breaks down. We move from the economic model of scarcity to the economic model of abundance. This changes the game completely. In this lecture we will explore this transformation.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
