Bro ...idtv really cheating customers.
Bcz present issue on channel's pricing .
But not telecast on channel's.
Really no need to change box .
Technical ly any box caches the tronspondes as well as channel's. Operator controls the channel's with the chip(sim) in the box. Operator allots channel's according to your subscription. Boxes also latest mpeg4 boxes. IDTV is have less channel's . so no need to go for HEVC compression of channel's. MPEG compression enough for now. So no need to upgrade box.
If company force to upgrade , company should give box at free of cost.
Earlier Tata sky replaced boxes free of cost.
