- Welcome to the English Pages of Czech Television (CT), the public service broadcaster in the Czech Republic
Czech Television (CT) broadcasts 24 hours a day on all its channels (CT1, CT2, CT24, CT sport) except channel CT :D/ CT art (6 AM – 2AM) where the “time sharing” mode on a single channel position is used. In the Czech Republic, analogue broadcasting ended in November 2011. All channels are broadcast via the most significant platform in CZ - terrestrial DVB-T network (59 % of households received DTT signals in 2013) and satellite DVB-S/S2 networks (29 % of households received DVB-S/S2 signals in 2013). Cable TV operators using DVB-C and IPTV platforms offer also Czech TV´s channels in their packages. The combination of different regional terrestrial networks allowed Czech Television to launch simultaneous operation of HD broadcasting on three channels CT1, CT2 and CT sport in DVB-T with H.264 compression in 2013. SD/HD simulcasting on channels CT1, CT2 and CT sport is also available on the satellite platform (DVB-S2 standard is used for HD channels).
Czech Television provides access services in its broadcast for people with special needs. It started offering DVB subtitles on its HD channels in the DTT platform in August 2014. This service enables hard-hearing or deaf viewers to use new features and in comparison with the teletext based subtitles to improve the quality of communication. Furthermore Czech Television provides Audio Description services for blind and partially sighted people based on the Receiver Mix system.
Czech Television is the leader in the field of hybrid television and services based on HbbTV standard in the Czech Republic. It has been offering these services since May 2012 when it launched the broadcasting of the first two applications (Teletext plus, Ice Hockey World Championship). CT´s HbbTV recently includes a whole range of applications including access to a rich internet archive with more than 85 thousand hours of recordings.
Czech television started experimenting on the Ultra HDTV formats in 2014. The UHDTV test has been launched in cooperation with České radiokomunikace as part of experimental DVB-T2 terrestrial broadcasting. The main purpose of the test is technical research and verification of the new technology features.
