Customers who sign up for dish network services ask some very pertinent questions sometimes. The most valid among them is why not broadcast TV? How is dish TV better than broadcast TV and in which way is it technically superior? The answer to this question is rather simple, as opposed to what people think it to be. Direct satellite TV services solve a very basic problem to emerge better than broadcast TV. As consumers you need to know what you are paying for. A little knowledge about satellite TV mechanisms will only hold you well.

To begin with dish network channels make use of satellites placed in the Clark Belt of the earth. These satellites pick up the dish TV signals which are transmitted by the broadcasting center on the earth. The satellites are geosynchronous in nature and adjust themselves according to the position and rotation of the earth. The satellites then revert the signals back to satellite TV receiver units on the earth. These are decoded by the satellite TV receiver and your TV is ready to beam those.

So what does dish network signals achieve in the process that broadcast TV cannot? It’s simple. As you know, TV signals travel in straight lines. Broadcast TV couldn’t get the signals across the globe because the earth is curved and the earth’s surface acted as a barrier. Dish TV signals take care of this problem. With the geosynchronous satellites acting as a receptacle, the problem of taking the signal over to the other side is appreciable solved. Satellite TV receivers take care of the rest.

After the dish network signals are received by the satellite TV receiver, work is not finished. The satellite TV receiver is an important element in the transmission of dish TV channels. It is not just receiving equipment. Satellite TV signals come in a packed bandwidth. Though the bandwidth is not narrow enough to distort signals or cause interference, the individual direct satellite TV channels needs to be fleshed out individually. That is done by the receiver.

The transmission of dish network channels, therefore, needs some basic components. It needs a broadcasting center to transmit the dish TV signals. It needs a satellite up in the sky to receive these signals and transmit them back to satellite TV receiver units on the earth. It needs a satellite TV receiver to unscramble the channels pack and play individual channels. This takes care of the problems faced by broadcast TV and also cable TV. The result is that you get seamless moving images and crystal clear sound effects. There is zero distortion and there is not cramping of channels on a narrow bandwidth, something that cable TV does.
