bro, I was telling that the customers can carry their Big TV STB to the Sunshine cetnres or Sundirect dealers and get the new STB from SD. They can theirselves plug in the new STB with the dish's cable in the home and watch SD channels. Technician visit is not at all required. That only I meant.
whereas for TataSky, they have to employ a technician to visit each Big TV customer's house and shift the dish antenna towards to TataSky's sat. Its going to be expensive. but SunDirect doesnt need to invest any money for the new customers from Big TV.
