"Around 23 cameras have been deployed by linking together three OB Vans with microwave and OFC cables to cover this mega event," the broadcaster said in a statement issued.
This live coverage is different from the Republic Day Parade that Doordarshan brings annually to India and the world as the January 26 Parade though panaromic and wide angles, concentrates on two specific areas -- the saluting base at Rajpath and the Amar Jawan Jyoti at India Gate, the statement said.
The logistics involved in this live telecast are complex as the area involved stretches for 1.5 kms from Rafi Marg to India Gate and will encompass the entire lawns to the north and south of Rajpath, it added.
The 23 cameras being used for the coverage have been placed in strategic positions to cover all the 40,000 participants, distinguished guests and Prime Minister Narendra Modi, who will be present at Rajpath on this historic occasion, the statement said.
"As the area required to be covered is much larger, the coverage of yoga day will be a much bigger challenge. Given their experience in covering mega events in the country, I am sure Doordarshan will measure up to that challenge," Prasar Bharati Chairperson A Surya Prakash told PTI.
In the statement, Doordarshan said it is using 13 raisers of five feet and ten feet height, covered with yoga motifs to place cameras while three Jimmy jip cameras are also being used to provide aerial views.
"One of the cameras have been additionally placed strategically at the halfway point on a hydraulic lift which can go upto about 50 ft high. This camera is at the junction between Rajpath and Janpath and can give the viewer an aerial perspective that will cover participants at both ends of the venue," the statement said.
