dB Broadcast completed a major contract from Siemens IT Solutions and Services to supply the BBC with HD coding and multiplexing services. This enables viewers to watch programmes in high definition on digital terrestrial TV (DTT).

The high definition service on Digital Terrestrial Television (DTT) became the first DVB-T2 HD service in the world with a technical launch at the end of 2009.

In a phased rollout, the BBC’s overall project will eventually lead to at least four high definition channels being available across the majority of UK households, including those from other public service broadcasters, such as ITV, S4C and Channel 4.

Using advanced statistical multiplexing, transmission, and compression technologies and dB’s Hawkeye products, Siemens IT Solutions and Services has engineered the system to avoid any single point of failure within the transmission chain. The B080 series of Hawkeye modules supports MPEG2, MPEG4, DVB and ATSC standards. The DTT services use more than 50 modules and provide near-seamless switching.
