I will try to explain with some more details
1. Cable: Presently every broadcaster has a master satellite (INSAT, ASIASAT, PAS, etc all C-band) where they uplink their signals and the signals are downlink from same satellite. Cable operators pick signal from various satellites (so we can see they have 3-4 big dishes on their roof top) and then selects the channels from satellite signals as per regional demand, then modulate and send via cable to his customers
2. DTH: DTH operator (
Tata Sky/DISH/DDD+) also downlink channels from Master satellite then select channels only they have purchased from channel provider (STAR/ZEE/
Sony/SUN/ETV/NEO/ESS). Then this channels are uplinked to their provider satellite (INSAT 4A/NSS6 - Ku band) from which viewers can directly downlink via small dish and receive channels as per package subscribed.
3. HITS: In HITS each broadcaster can uplink his channel signals (Free or encrypted) to a dedicated satellite (C/Ku Band) from any location in country. The HITS operator (or license holder) can downlink this signals from this single dedicated satellie and send select channels as per regional demand and send it to his users in conventional analog format (so no need of STB, but will have limitations of cable) or in digital format which will need STB to decode channels and can also provide services like EPG, ACTIVE (may be its somewhat similiar to present digital cable providers)
I understand the 1st & 2nd part.
In the 3rd part some what i have understand if i am correct what you said it means that all the broadcasters like sony, star, zee, ESS, Sun, Etv need to uplink their channels in a particular satelliete i.e., all the channels need to uplinked to Insat 4A(Eg) and then an MSO with only one dish can select the channels what he wants and then give it to the end customers right
