The CRa, shot for Czech
national transmission company Ceske Radiokomunikace, says that it has successfully
tested DVB-T2 with the HEVC codec and become the become the first company in
Central Europe that successfully did the DVB-T2 HEVC test.
According to CRa, its five month trial was undertaken
in cooperation with the public broadcaster Ceske Televize (CT) and the trail
will officially end this on November 30. In addition, CRa also adds that the
HEVC codec, in conjunction with DVB-T2, is part of the new D-Book published by
the Czech Telecom Office (CTU).
The CRa is now interested in undertaking additional
tests of live broadcasts, in SD, HD and Ultra HD via DVB-T2 HEVC codec in order
to verify the optimal set of technical parameters for future DVB-T2 networks. It
is negotiating with the CTU to secure authorization for such tests.
About HEVC
High Efficiency Video Coding (HEVC), also known as
H.265, a successor to H.264/MPEG-4 AVC (Advanced Video Coding) that said to
double the data compression ratio compared to H.264/MPEG-4 AVC at the same
level of video quality. It can alternatively be used to provide substantially
improved video quality at the same bit rate. It can support 8K UHD and
resolutions up to 8192x4320.
About DVB-T2
DVB-T2 is the world’s most advanced digital
terrestrial television (DTT) system. This system transmits compressed digital
audio, video, and other data in "physical layer pipes" (PLPs), using
OFDM modulation with concatenated channel coding and interleaving. The higher
offered bit rate, with respect to its predecessor DVB-T, makes it a system
suited for carrying HDTV signals on the terrestrial TV channel (though many
broadcasters still use plain DVB-T for this purpose). A multitude of DVB-T2
HEVC codec set-top boxes and integrated TV receivers are now available, such as
SDMC hybrid DVB-T2 HEVC codec set-top box DV7810-T2 and SDMC OTT
HEVC codec set-top box DV7819. The price
difference between comparable DVB-T and T2 integrated TV sets is already
negligible.
