scope:
Verify in a field test, the possibility to receive in vehicular mobility mode the DVB-T emissions broadcasted by the already on air networks, which has been developed and implemented to ensure fixed antenna reception through a complex system of reception.
DVB-T mobile reception can easily achieve at least three major advantages with respect to DVB-H broadcastings:
- seamless use of already existing network infrastructures (no need to further capex);
- remarkably higher reception quality, both in terms of screen resolution and of available bit-rate, compared to the reception quality currently available or expected by DVB-H broadcastings, allowing therefore to install high-quality display up to large-sized screen on board of vehicles (cars, vans, coaches, tramway cabs, trains, ...);
- availability for the end user of a wide range of subscription-free contents.
We assumed that this type of mobile DVB-T reception can be achievable by the use of "diversity" receivers with carriers coherent sum (CCS) system.
