Bridge Technologies monitors DVB-T2
September 9, 2011
Bridge Technologies has launched its complete solution for monitoring and analysing DVB-T2 transmissions, with comprehensive support for the T2-MI stream format. DVB-T2 is estimated to be the transmission format of choice for 70 per cent of the broadcast infrastructure currently under construction, and DVB-T2 networks are already coming on air in most countries in Europe, Africa, and the Middle East.
Part of the DVB-T2 specification, T2-MI is used for contributing streams from the master headend to regional sites in a highly efficient and controlled form. T2-MI provides important advantages for operators, especially in single-frequency network (SFN) applications, where it ensures accuracy, allows all scheduling and allocation decisions to be made at the central headend, and lets each modulator in the network unambiguously create an identical on-air signal. However, the complex T2-MI formatted streams are structured in a way that made them inaccessible to standard monitoring systems — until the introduction of the DVB-T2-MI option for the VB120 or VB220 probes.
