Indian Institute of Technology Rajasthan (IITR) and National Instruments India have jointly developed the intellectual property (IP) for a digital radio mondiale (DRM)-based transmitter.

According to the company, this broadcasting system has been proposed as a "high-quality digital replacement for analogous broadcasting in AM and FM/VHF bands." It allows rural and remote parts of India to access both local and international transmissions.

They have signed an MoU to record their intention of starting and running a centre of excellence on communication and physical layer technologies at IITR. As part of this MoU, a National Instruments Advanced Communication Laboratory was established at IITR in November 2010.

"Our research and development centre in Bangalore works on cutting-edge topics in the area of image processing, graphical system design software and communication signal processing. We leverage the rich intellectual expertise available in Indian universities by direct hiring and forging strong partnerships, like the one with IITR," said NI India MD Jayaram Pillai.

DRM, which has a lossless transmission range of about 100km, allows flexibility for the system to optimise according to the local environment conditions through an exchange in bit rate capacity, spectrum occupancy, and robustness mode and transmission power.

IITR students are currently working on embedded version of such a system, for potential application in broadcasting special services such as weather forecast, national news, important announcements, educational presentations etc. for rural India.
