Digital Television is the set of image and sound transmission and reception technologies through digital signals. Unlike analog television, Digital Television encodes signals in binary form. In this way, it is possible, thanks to the different existing signal compression formats, the transmission of several signals in the same channel and the creation of interactive applications through return channels between the consumer and content producer.

Thus, the available bandwidth is used to transmit numerous packets of compressed information, instead of one uncompressed signal taking up all of it. A flow of up to 20 Mb can contain 4 or 5 different programs, in a single transmission channel, without counting on the retransmission of information, which would go from the device to the operator.
