This new technology gives access to higher level of using the information that is transmitted from the provider to the customers. That means the signal is converted. Moreover, it is many times better than the analogue one. The digital signal content converted analogue wave to binary code. Consequently, we have to decode this data, because we need to see more than '0'' and '1''. Exactly for that is the presence of the digital receiver. Its content is decoder, demultiplexor, decrypt integrate device and demodulator.

The decoder catches the correct data which is for it and starts to execute the all default procedures and functions. Indeed, it uses CRC (this is a control summary that checks and verifies if there are errors).

Next is the demultiplexor. This device divides every single multiplexed channel to different programs like Diema, Nova TV, BTV, Canal 1 etc.

The last but not least, is the demodulator. Its function is to proceed the incoming data in correct format for viewing. That means, we will be able to watch digital television with its full advantages on our home TV.

Additionally, it can be said that there are two types of extenders (this is one of the many names of the digital receiver), wired and wireless. With the first one, we can enjoy the excellent performance of quality and bits rate. The cables that are used are UTP CAT 5 and RG 45 Ethernet.
