Demonstrations Show HEVC Encoded
Content In Multiple UHD Services Utilizing 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, DVB continues to make progress
towards the next phase in the UHD standardization
process.
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. Utilizing
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 Mbit/s.
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. It enables channel
bonding of up to 3 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 7 HEVC encoded High Definition
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.
