But technoglitch bro: here there are two sub questions and issues:
If they keep analog on as most don't have STB installed:
1. wouldn't it be illegal, and woudnt it invite strict actions from TRAI/broadcasters
2. in the pic I posted they say DAS 3 MSO need to sign a new agreement, and old agreement will be null and void, they also say that they have to specify the analog cut off date on the new DAS agreement form. So if MSO doesn't mention the date he wont get the agreement and channels. And From jan 1st broadcasters will switch off services.
