Reliance’s Big TV is not available or very rarely available in market DD Direct carries only Free to Air channels Sun Direct have their operations curtailed to South India and though initially, they had a big advantage due to regional content, this has been greatly reduced with other companies also adding regional channels.
Based on my experience I will briefly discuss each one of them- Tata Sky- Tata Sky has established itself as a premium DTH brand and is the most sought after among the urban and upper-middle class. They are known for their quality and innovations such as Tata Sky HD PVR Transfer. In terms of channel, they might lag behind a bit. Also, their packages are a bit on the higher side. Example, for English movies and entertainment channels you will have to pay Rs. 530 per month plus Rs. 175 additional for HD Access. Videocon D2H- Brand Videocon learning from its mistakes in the LCD-LED segment, has focused of services for the D2H segment. They are the only company who manage the after-sales service themselves and have not given it to the franchise model. However, they still have scope for improvement. Regarding the product, like Tata Sky, they have been a pioneer in bringing new products- RF Remote being one such product. They also have 500+ channels and services with very competitive monthly packages. However, a number of HD channels are still limited. Dish TV- The oldest player, it was once taken aback by the entrance of so many new players. However, it fought hard to continue to be the market leader. It is probably the most popular brand among the middle class due to its low entry-level pricing and with the launch of its regional line- Zing. It can take proud on its large network of dealers and maximum channels including HD channels. Service is one area where Dish TV can improve upon. Airtel Digital TV- Airtel is considered as the market leader in telecom sector not just in numbers, but quality also. However, for DTH segment, it has relied too much on its telecom brand value. While the product quality is good, it is their services which are not up to the Airtel standards. Also, they have a weak network of dealers and lack of transparency in terms of packages. Their website will give you an idea of their lack of interest in DTH segment.
