 Digital Video Broadcasting transmission medium

 There are many ways the digital data is transmitted by DVB systems:

Satellite (DVB-S)

Here Digital data is delivered by means of a Communication satellite and received by a Dish Antenna which is decoded by the set-top box.


Some operators of Satellite transmission are: (this is not comprehensive list, just listed some places where I have worked so far)

India:  Tata Sky, Airtel Digital TV, Sun ,Dish TV, Big TV, Videocon D2H

South Africa:  DSTV, Top TV

Israel:  Yes!


1)     Cable (DVB-T/ DVB-H)

Cable television is a system of providing television programs to consumers via radio frequency (RF) signals transmitted to televisions through coaxial cables or digital light pulses through fixed optical fibers located on the subscriber's property.

It is mostly available in North America, Europe, Australia and East Asia.


2)     Terrestrial

Digital terrestrial television broadcasts land based (terrestrial) signals

DVB-H (handheld) is a superset of DVB-T with little extra features to support handled devices.

In India, Prasar Bharti (also known as DD for Doordarshan) started DVB-H trials in various metropolitan areas to test the reception quality of the broadcast coverage. Moreover, DD is currently broadcasting 8 channels in the New Delhi

In South Africa, DSTV provides DSTV mobile which works on the handheld device called drifta which receives the DVB-H signals. Drifta converts this DVB-H signals to wifi signal.



 I have no clue about this.
