DTT (the broadcast of digital television services using terrestrial radio transmission) was launched on 31 December 2007 and signals are transmitted by the principal transmitting station at Temple Hill, which serves as the hub of the transmission network, followed by the 28 transmitting stations completed in 2008-2011. The current DTT coverage has extended to all districts in Hong Kong reaching at least 99% of the population.
DTT signals are received and distributed to viewers by standalone antenna and/or in-building communal aerial broadcast distribution system, as illustrated below.
