Broadcasting and Television Media

DD Bharati was launched in January 2002 as Doordarshan's 24-hour cultural channel. It focused on Indian art, culture, music, dance, and heritage programming, distinct from news or auto-focused channels.

Star News was launched in February 1998 as a 24-hour Hindi news channel. It was one of the first private news channels in India, launched by the Star Group before being later rebranded.

Star News was launched in February 1998 as India's first 24-hour Hindi news channel. It was a joint venture between Star Group and an Indian media company. This launch revolutionized news consumption in India by bringing round-the-clock news in Hindi to television viewers, setting the stage for the boom in 24/7 news channels that followed in subsequent years.

FM stands for Frequency Modulation, which is a method of encoding information in a carrier wave by varying its frequency. This is different from AM (Amplitude Modulation) which varies the signal's strength instead.

Telecom signals, being electromagnetic waves, travel at the speed of light in vacuum (approximately 3×10^8 m/s). This includes radio signals, microwave transmissions, and optical fiber communications.

The picture tube (also called a cathode ray tube or CRT) is the component in traditional television sets that converts video signals into visible images. It uses electron beams to illuminate phosphors on the screen, creating the pictures we see.

 Micro wave is the medium of satellite communication.

'Man vs Wild' (originally 'Born Survivor') airs on Discovery Channel, featuring Bear Grylls. Aaj Tak is Hindi news, MH One is entertainment/music, History Channel shows historical documentaries. The show is known for survival skills demonstrations.

Fiber optic cables use light signals to transmit data at speeds approaching the speed of light, offering much higher bandwidth and transmission speeds compared to twisted pair (electrical) or coaxial cables (electrical with higher frequencies).

This down link common channel follows each frequency correction channel slot by 8 BPs.

This channel repeats once every 51*8 BPs and it is used to identify beacon frequency.

This uplink common channel is a full rate common channel and transmits one time slot, each of 8 BPs.

This signaling channel occupies one time slot(.577 ms) in every 26 frames.

This is a form of electronic media.

Under the contract, EADS-Astrium is the prime contractor in charge of overall programme management and would build the communications payload, while Antrix/ISRO would build the satellite with a lift-off mass of around 2.5 tonnes and power of 3.2 KW.
