Czech Successfully Tests DVB-T2 with the HEVC Codec
The Czech national transmission company Ceske Radiokomunikace (CRa) says it has successfully tested DVB-T2 with the HEVC codec.
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.
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.
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.
Founded in 2003, SDMC system and products are widely used in telecom, broadcasting, hotel, hospital, school, residential area and other industrial in both domestic and oversea.
