The DVB will use its presence at IBC to demonstrate HEVC-encoded content in multiple UHD services utilising DVB-S2X and multiple HD services via DVB-T2.
Following the approval in July of the specifications for the use of HEVC in the DVB environment and DVB-UHDTV Phase1, which was seen as a significant step in the road to Ultra High Definition TV services, at this year’s IBC, DVB’s main concentration will be to demonstrate how the coding efficiency of HEVC can be used to increase the capacity of the DVB-T2 terrestrial platform as well as for the new DVB-S2X satellite standard.
Utilising HEVC encoding, multiple UHD services will be delivered using DVB-S2X and multiple HD channels over DVB-T2. The DVB-S2X demonstration will highlight the new standard that offers spectral efficiency of up to 50% for professional applications. S2X will be implemented with HEVC to deliver 4 UHD signals at a data rate of 100 Mbps. DVB-S2X provides more choices for roll-off factors as well as additional modulation and Forward Error Correction options that allow for the more efficient use of satellite transmission channels, according to DVB. It enables channel bonding of up to three satellite channels, which support higher aggregate data rates and allow for additional statistical multiplexing gain for services such as UHDTV.
In another demonstration up to seven HEVC encoded HD channels will be delivered in one multiplex using DVB-T2 in a robust mode suitable for small indoor antennas and portable reception. Both fixed reception and mobile reception will be demonstrated.
