Earlier this month the
citizens of Caracas had an opportunity to experience interactive DTV using MHP first hand when a technical demonstration was set up to
coincide with the start of the Copa América football tournament. At six
different points in the city, each located in the crowded commercial
centre, a public demonstration point was installed.
These demonstration points included an old TV set
and a new plasma display, both receiving the standard analogue
transmissions. Alongside these there was another old TV set, but this
one was connected to a standard low-cost MHP-enabled DVB-T set-top box costing less
than US$ 50. It was clear to everyone that viewed the demonstration
that the DVB-T transmissions offered a superior picture, even on a
standard TV set using a small indoor antenna.
The opportunity was also taken to demonstrate the benefits of the
MHP open middleware standards for interactive TV. Two applications were
broadcast along with the DVB-T service. The first allowed users to vote
for the team they thought would win the match that was in progress at
that time. The second application, as an example of the potential of
MHP for eGovernment, allowed users to enter their ID card number in
order to find out the location of their local polling station for
elections.
A DVB-T transmitter had been installed at a high site
in Caracas , providing coverage to almost all of the city for the demonstration. The trial was sponsored by INDRA, a Spanish company and also by CONATEL, the Venezuelan regulatory authority for communications.
The Venezuelan authorities are currently considering which system will
be adopted for digital terrestrial TV. DVB-T is one of the options they
are considering.
