Before there were Antennae TVs where we used to put a antennae in our roof or terrace . There used to be a operator in our city who transmits the signals to our antennae . And in this way got to see TV in no cost .
Then came the era of cable TVs which is also used nowadays . There used to be one big satellite transmitter and the signals were used through wires to people's residence . By this sometimes the cables theft , hence piracy was done .
So this is all the knowledge I had . It is not copied knowledge, its my knowledge thats why it is called AnupKnowledge .

Then came the era of cable TVs which is also used nowadays . There used to be one big satellite transmitter and the signals were used through wires to people's residence . By this sometimes the cables theft , hence piracy was done .
Nowadays most people are using DTH services to watch TV . DTH stands for Direct To Home . There are mainly 6 companies providing these services . All the channels we see are part of a broadcaster company . Broadcasters contain a group of channels in them . They have their own productions , shows and a network of it. They broadcast all their programs and shows through satellites . They make bunch of timings of various programs . The signals sent to the satellites are in encrypted form and are secure . They cant be decrypted in between . The signals are then sent to the DTH service providers . They first collect the data and store it . They keep a list of all the channels . Then the DTH service providers also use satellites to broadcast a TV channel .

They take these satellites in rent . In India all the service providers take those satellites from ISRO in rent . They have a tie-up with ISRO . You must have noticed that all the antennae in our roofs of different service providers face to different directions . It is because of the signal they get . The satellites have transponders . These transponder support nearly 40 channels each . And these transponders are very expensive to be rented . And each transponder costs around 10,00,00,000 INR/year . So all the service providers have many channels available . Hence a lot of money is spent on broadcast of these TV channels . These service providers connect all the broadcasts to your set top box . By which the signals from satellites comes to your antennae .
But from here how the service providers get profit ?
They take the channels from the broadcaster in a certain amount per month and sell us in a little more price to gain some profits . If a broadcaster charges 10 rupees per month from the service provider , the DTH service providers may charge 15 rupees, may be 12 rupees depending upon them . All the DTH service providers have different pricings and also different way of marketing .
You may have seen that various service provider provide many packs . The cost here may be less , but the amount they charge from us will definitely be more than they give to broadcasters .
In this way they show many ads in their DTH and also take money from the users , because after all they have to spent a lot on satellites , broadcasting , customer cars etc.
