What are S‐DMB services?
The satellite digital multimedia broadcasting service (S‐DMB) is basically a digital mobile
broadcasting service (mobile TV service) using satellites. Broadcasting satellite service
transponders are used in satellites to provide one way S‐DMB services.
S‐DMB is used for a satellite‐based national service for delivery of video, multimedia and
information services via satellite to fixed and mobile receivers in vehicles and mobile phones
across India.
1.5 What was Devas offering?
Antrix entered into an agreement with Devas Multimedia Limited (Devas) in January 2005 to
introduce a new S‐DMB service (Devas service) in the country by launching two satellites,
PS1 and PS2. The Devas service was to be a hybrid system delivering internet services
including multimedia, information services via landline as well as satellite and terrestrial
wireless systems to fixed, portable and mobile terminals, tailored to the needs of various
market segments. S‐DMB technology provided two‐way audio/video services and internet
services, both for fixed and mobile receivers within the coverage area of the satellites.
