Telefónica O2 will launch what will be the first HD channel in the Czech Republic on July 2. The service – Czech Television (CT) in the format – will be offered to the telco’s 36,000 IPTV subscribers and also made available on its DTT multiplex. Telefónica O2 and CT began HD trials in Brno last autumn, shortly after the launch of the IPTV platform O2 TV.
