Industrial Visit Report to Doordarshan Kendra

An Industrial visit to Doordarshan Kendra (Prasar bharti); Raipur Chhattisgarh was organized by Department of Electronics & Telecommunication Engg., CSIT Durg on 15’th March, 2016. Total 23 students of 4th Semester & 3 faculties of the Department attended the same. The purpose of this visit was to develop interest among the students and to enhance their practical knowledge towards Communication Technology. This visit was arranged by Mr. Shashikant Agrawal (Sr. Assistant Professor, Electronics & Telecommunication Engg. Deptt. & I/c Industrial Visit)  & Co-ordinated by Mr. R. K. Sahu (Associate Professor, Electronics & Telecommunication Engg. Deptt.) , Mr. N. K. Sahu (Sr. Assistant Professor, Electronics & Telecommunication Engg. Deptt.), Mrs. Sapna Verma (Teaching Assistant, Electronics & Telecommunication Engg. Deptt.), under the supervision of Dr. Amit Agrawal (Professor  & Head, Electronics & Telecommunication Engg. Deptt.).

At Doordarshan Kendra, we were received by Doordarshan team member Mr. S.K. Jain (Assistant Engineer. He told us that there are 2 Studio’s of Doordarshan i.e. studio A studio B (new).

 Then he took us to the studio where they conduct gathering program. Mr. S.K. Jain (Assistant Engineer) gave us some technical information about the position of lights i.e. backlight, front or key light & kill Light and cameras, as they are the most important part of their programme. There are total 3 ELG cameras & 1 ENG camera in that studio .Then he showed us the working of control room. At control room there are two VM i.e. Video mixing machine, which mix the video output of those ELG cameras. He demonstrated us that how the video from CCU (Central Control Unit) comes to VTR (Video Tape Recorder) then to CCVS (Color Composite Video Signal).Then he took us to Audio control room where he showed us the tally distribution and audio console, from which they control the audio signals by altering the Frequencies of sound. Mr. S.K. Jain also explained about the different frequency band i.e. HF, VHF, UHF etc, Transmitter & Receiver, uplink & downlink frequency, Line of sight, analog & digital signal, resonance, microwave communication, satellite communication, waveguide, multiplexing, RF, digital encoding, quantization, noise, earth station, power supply, signal transmission, and many more such devices and principles about which we will study in current semesters as various subjects.
We took a short break thereafter, we headed towards transmission part. Transmission part explained by Mr. S. K. Jain (Assistant Engineer). There is a transmission tower of height 150 meter (105 M is concrete & 45 M of antenna).Then he informed us how the transmission of signals takes place through satellite. He took us to the Blower Room where the surrounding air comes, filtered and retransmit to the machines for their good & efficient working. Then he took us to the earth station where all the controlling of Doordarshan Kendra; Raipur is done electronically through a software named: “Evolution 5000 MEM Equipment Monitor”. From this tour we came to know about the three big Enemies of Electronics: Dust, Moisture & Temperature, for the achievement of an electronic engineer we should cope-up these 3 enemies.

In Doordarshan Kendra (Prasar Bharti), we visited the entire studio like control room, music studio, playback studio, talks studio, Transmitter Section, recording room; etc. All the students highly enjoyed their entire visit. It was an amazing experience of fun & learning, which we all have memorable reminiscences.

Last but not the least; the trip was exceptionally good & knowledgeable for all of us. We look forward to make such visits in future too as technical visits gives practical and better understanding of subjects to students and update their knowledge. We thank our CSIT management & E&Tc. Deptt.  for giving such a wonderful opportunity.
