7.5.2.2. Television (T.V.)

Television broadcasting has emerged as the most effective audio-visual medium for disseminating information and educating masses. Initially, the T.V. services were limited only to the National Capital where it began in 1959.

Television is a powerful medium combining sound and visual elements. It began in 1959, focusing primarily on the National Capital of India, which means only the capital city had access to this new form of media at the start. This positioned T.V. as a revolutionary tool for mass communication compared to other forms like radio or newspapers, which were more widely used before.

Think of television as the bridge between a book and a live theater performance. While a book offers information through text only, and a theater connects with an audience live, T.V. combines both visuals and audio, creating a more engaging experience for viewers.

After 1972, several other centres became operational. In 1976, TV was delinked from All India Radio (AIR) and got a separate identity as Doordarshan (DD).

Following its initial launch, T.V. services expanded beyond Delhi to other significant locations across India by 1972. The split from All India Radio in 1976 meant that T.V. gained its identity as Doordarshan, which allowed it to develop its programming tailored specifically for telecasts rather than being a mere offshoot of radio broadcasts.

Imagine if a café decided to expand its menu and open a new branch specialized in desserts. Initially part of a general restaurant, this dessert café now focuses on pastries and cakes, just like Doordarshan began focusing on television content.

After INSAT-IA (National Television-DD1) became operational, Common National Programmes (CNP) were started for the entire network and its services were extended to the backward and remote rural areas.

With the launch of INSAT-IA, a satellite allowing the transmission of television signals, the network could broadcast across larger areas, reaching rural and underserved regions. This initiative aimed to provide educational and informative content to all parts of India, particularly targeting communities that had limited access to media.

Think of this as a library that initially only serves a big city but, through a new delivery system, can now send books to small towns and villages. Just as this helps everyone access literature, INSAT-IA allowed everyone in India to have access to television.

Satellites are mode of communication in themselves as well as they regulate the use of other means of communication. However, use of satellite in getting a continuous and synoptic view of larger area has made satellite communication very vital for the country due to the economic and strategic reasons.

Satellites facilitate communication and enable various services, including television broadcasts. Their ability to provide a broad perspective of land and weather patterns is vital for both economic planning and national security, making them crucial for delivering timely information and ensuring operational awareness.

Consider a satellite like a gigantic pair of eyes in the sky that can observe and relay information about the land below, similar to how a security camera works for a building, continuously monitoring and sending that data to ensure safety and awareness.

Satellite images can be used for the weather forecast, monitoring of natural calamities, surveillance of border areas, etc.

The ability of satellites to send images and data back to Earth aids in critical functions like predicting weather patterns, managing disaster responses, and ensuring national security. This information can guide public safety measures in the wake of natural disasters or other emergencies.

Imagine being a weather forecaster who can use a futuristic telescope to see incoming storm systems and warn the public in advance. This advance notice can help people prepare, just as satellite data helps authorities prepare for and respond to disasters.
