The 2018’s cycling Tour of Spain “La Vuelta” has been a great success. RTVE -the Spanish public radio/television entity- has performed a depth coverage of the entire event. The mobile links of helicopters and motorcycles to the base station have been made with digital television ISDB-T technology..

Why has ISDB-T standard been used for TV links instead of DVB-T or DVB-T2?
The advantage of the ISDB-T system is its robustness in movement. This is the key reason for RTVE to select ISDB-T on their mobile links.
ISDB-T is a standard developed in Japan and widely used in South America. Together with DVB-T, DVB-T2 and ATSC, they are terrestrial broadcasting standards supported by PROMAX TV and spectrum analyzers.
The "La Vuelta a España" is a challenge. Some of the stages pass through mountain roads, with multiple tunnels and rugged landscapes that makes it difficult to transmit-receive real time images from mobile units. With the ISDB-T standard, transmitted signals are more robust. It takes longer before they get unlocked at they recover faster. This is what makes the difference with the DVB-T and DVB-T2 systems adopted as broadcasting standards throughout Europe.
