Newtec demonstrates UltraHD broadcasts with DVB-S2X

June 10, 2014 // By Nick Flaherty
Belgian encoder maker Newtec has demonstrated the world's first 4K UltraHD transmissions using the new DVB-S2X protocol.

The new protocol, published in February, defines extensions to the existing  DVB-S2 protocol to give 50% more efficiency in professional applications and up to 20% for direct to the home (DTH) TV broadcasts.

The demonstration with Malaysian satellite operator MEASAT at the CommunicAsia show in Singapore has the 4K UltraHD feed uplinked via MEASAT's teleport in Cyberjaya, Kuala Lumpur, and delivered live via MEASAT-3 satellite in C-Band, using Newtec’s upgraded DVB-S2X modulation equipment

The standard extensions are implemented as a software upgrade to the existing FPGA-based products and provides a standard mechanism to bond carriers together, creating one big transmission pipe for multiple 4K programs over existing transponders.

The extensions also provide finer granularity of modulation and FEC options combined with sharper roll-offs and enhanced signal to noise ratio down to -10dB. Channel bonding of up to 3 satellite channels will support higher aggregate data rates and allow for additional statistical multiplexing gain for high data rate services such as UltraHD. The mandatory implementation of Variable Coding and Modulation (VCM) in receivers offers the possibility of increasing the spectral efficiency for UHD services, while guaranteeing service continuity during heavy rain by simulcasting highly protected SD components. A finer granularity of modulation and FEC options also allow for improved operational flexibility.
