Not practical also for DPOs... DPO carries large no. channels. DPO's cost remains same if 20 customers watch all 400 channels or 20 customers watch 20 unique channels(20×20)... Why should DPO charge less for 20 channels if its customer cost is same for all. Nobody will become a DPO to serve 20 channels to a single customer, unless all cutomers watch common 20 channels.
All those who want common 20 channels with 0 or 20 rs NCF can make your own association and make a DPO, take govt loan. Do agreements with broadcasters of those 20 channels.. lets see hw ur DPO company survives...
