- Tata Sky leads the single brand satellite capacity with 24 transponders
- Dish TV leads the multi-brand capacity with 30 transponders (DishTV+d2h)
A Geostationary communication satellite is the beating heart of a DTH system and the transponder capacity is its very lifeforce. Just like the spectrum holding capacity determines the efficiency of a telecom operator, the transponder capacity determines the efficiency of a DTH operator. A typical Ku band transponder in the DVB-S2 system can carry as many as 20 HD or 40 SD channels with MPEG-4 compression standard.
Currently, there is 1 state-owned and 4 private DTH operators (Dish TV operates under 2 brands) providing service in India. The department of space (DOS) permits DTH operators to only use satellites commissioned by Indian Space and Research Organisation (ISRO) or in case there isn’t sufficient capacity on ISRO satellites then they are permitted to use capacity leased by ISRO from foreign satellites.
Here we will enlist the satellites used and the transponder capacity available to all DTH operators along with their current TV channel count. This is intended to help potential subscribers get a birds-eye view and make an informed choice while picking a DTH service provider. Dish TV and d2h have been listed separately since they operate as individual brands and have separate satellites as well.
