The actor is the host of Satyamev Jayate on Doordarshan.
Speaking to The Times of India, he said: "The show is for everyone. It's an effort to understand ourselves, to make our lives better. The show gave me a chance to connect with common people from different states and cities."
Khan unveiled the programme's theme song 'Tera rang aisa...', which was written by Prasoon Joshi and composed by Ram Sampath.
Describing the piece, he said: "I wanted a romantic song because I have love in my heart for my country, like every Indian. The song is so beautiful; the lyrics will make you fall in love."
The 3 Idiots star revealed that he has been working on the show for the past few years and has shot 13 episodes. He has reportedly delayed the release of his forthcoming film Dhoom 3 for the programme.
The 47-year-old actor also revealed that he had been offered a game show, but chose something closer to his heart.
"Television is a powerful medium and I wanted to use it properly. I have taken a route which I understand. I am an entertainer. I am doing things which are close to my heart, things I enjoy the most without compromising with people's emotions," he explained.
Khan has previously said Satyamev Jayate is his most ambitious project.
The programme will be dubbed in all regional languages and will be telecast on Doordarshan at the same time.
