How the T.V. works:
ADVERTISEMENTS:
Television works with the help of electronics. We buy T.V. receivers that receive the figures and the sound from a T.V. centre. The main feature of a T.V. centre is its tower. The figures beamed on the T.V. receivers may be still or in action. These figures may be plain or coloured.
Television in India:
The first regular T.V. broadcasting started in Delhi in the year 1965. The T.V. station in Bombay was installed in the year 1972. The T.V. tower in the Bombay T.V. station is the tallest and the self-supporting. T.V. tower in our country. It is three hundred meters high. Later, T.V. stations were founded in Amritsar, Srinagar and Calcutta. From 9th August 1975, Calcutta became a T.V. City. The Indians are now manufacturing T.V. receivers. In Orissa, Government enterprise at Bhubaneswar is making T.V. sets.
On the last August 1975, the TV programmes were beamed to two thousand and five hundred villages in six states of India through Satellite Instructional Television Experiments. These six states are Adhra Pradesh, Bihar, Karnatak, Madhya Pradesh, Orissa and Rajasthan. These villages were provided with 2000 special T.V. sets to receive programmes directly from the artificial earth satellite stationed over the Indian Ocean by the National Aeronautical and Space Administration (NASA) of the United States of America. These special T.V. sets were designed by the Indian Space Research Organization (ISRO) at Ahmedabad.
ADVERTISEMENTS:
In Orissa, on the 1st August 1975 the then Chief Minister Mrs. Nandini Satapathi Inaugurated the Satellite Instructional programme in the village Ankarntipur in the district of Dhenkanal. That serves the selected villages of Dhenkanal, Sambalpur, Balangir, Kalahandi, Sundargarh and Keonjhar districts.
Usefulness:
The usefulness of TV certainly much more than radio. TV is the best medium for mass education about public health, sanitation, improved cultivation, indigenous industries, small savings, family planning and personal hygiene. It is the best medium for mass-education in literacy and preliminary science. It is also the best medium for teaching higher science and geography to the students in colleges and universities. It is also the best medium for audio-visual entertainment through songs and play broadcast through it. It is also the best medium to bring us home the tragedies of war, the worth of nature and the development works going on at home and abroad.
