The DVB Steering Board has approved the commercial requirements for the DVB-C2 specification. It comes 14 years after the development of the DVB-C specification that has become the standard for digital broadcasting on cable networks around the world.
The demand for more advanced services including the introduction of HD and VOD has pushed the 256 QAM modulation system to its limits on 862MHz systems. High Fibre Coax (HFC) networks are being optimised to provide even higher modulation schemes than are presently offered by DVB-C.
The DVB has therefore set in motion a process to develop a set of commercial requirements and in its call for technology is looking for contributions towards a specification that will serve the cable industry for between 10 and 12 years.
The satellite DVB-S2 standard is already being used by a number of operators and progress is also being made on the terrestrial DVB-T2.
The deadline for contributions is June 15.
