DVB Demonstrates New Platforms To Deliver UHD and HD Services
The Digital Video Broadcasting (DVB) consortium is showcasing new digital video broadcasting and distribution standards at IBC 2014, including low-noise Ultra-HD TV standards that are expected to be in place by 2017/18.
Demonstrations showed how the coding efficiency of HEVC compression can be used to increase the capacity of the new DVB-S2X satellite standard,
as well as for the DVB-T2 terrestrial platform. Utilizing HEVC encoding, multiple UHD services will be delivered using DVB-S2X, and multiple HD channels over DVB-T2.
This latest breakthrough in the road to UHDTV services follows the recent approval of the specifications for both the use of HEVC in the DVB environment and DVB-UHDTV Phase1.
The DVB-S2X demonstration will shows utilizing HEVC encoding will allow 4 Ultra HD channels to be transmitted over a 36MHz channel at a data rate of 100 Mbit/s. DVB-S2X offers an increase in spectral efficiency of up to 50% for professional applications. It 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.
The DVB-T2 demonstration showed up to 7 HEVC encoded High Definition channels being delivered in a single 8MHz DVB-T2 channel at 64 QAM and at a data rate of 26.56 Mbit/s. This robust transmission mode works well for indoor reception using small indoor antennas, as well as for portable reception. Both fixed reception and portable reception were demonstrated.
The arrival of HEVC is a logical time for mature European DVB-T markets to consider switching to DVB-T2 and to introduce HEVC encoded services at the same time.
The UK, for example, which already uses DVB-T2, would more than double its number of HD channels from 5 per multiplex to around 12 by switching to HEVC, thanks to the combined efficiency of HEVC, DVB-T2 and statistical multiplexing.
Germany plans to launch DVB-T services with HEVC using the indoor reception mode to deliver up to 7 HD channels per multiplex to fixed and mobile receivers.
Staying at IBC, at the the IBC Future Zone, Japanese NHK once again wowed visitors with Super Hi-vision (8K). NHK has produced cameras to support the the 8K/120Hz format.
8K provides 33 megapixel ultra high-definition images. The frame frequency has been standardized for 120Hz as the video parameters, as well as 60Hz.
NHK collaborated with FIFA to produce 8K images of the 2014 FIFA World Cup in Brazil. The finest moments of play were captured with 120Hz miniaturized 8K Cube Camera. Images were be shown at IBC 2014.
Today's 8K iteration is expected to undergo public trials from 2016, culminating in a full service by 2020.
IBC, th biggest display of broadcasting equipment in Europe, is taking place in Amsterdam in the Netherlands from Friday 12th to Tuesday 16th of September.
