TV Tower and the LTV television headquarters in Zaķusala were officially completed. During the Third Latvian National Awakening, the broadcaster became more open to Glasnost-style freedom of expression and criticism of Soviet rule in Latvia, most notably in the form of the Labvakar political talk show (1988–1993). The buildings in Zaķusala were one of the locations defended during The Barricades. During the 1991 Soviet coup d'état attempt troops of the OMON unit seized the LTV building on August 21, suspending broadcasts for two days. 1993–2013 On 1 January 1993, Latvian Television and Radio Latvia became members of the European Broadcasting Union (EBU). On 2 February 1998, LTV along with LNT, Channel 31 (now TV3) and TV Riga (later TV5) converted to PAL color. In 2003, LTV2, the second channel, was rebranded as LTV7. In 2008, LTV started broadcasting in digital terrestrial TV standard in MPEG2 format, changing to MPEG4 format on 1 August 2009 as the telecommunications company Lattelecom has been chosen to be the official integrator of digital terrestrial TV in Latvia. Analogue distribution of LTV7 finished on 1 March 2010. LTV completely finished broadcasting LTV1 in analogue format on 1 July 2010. Both LTV channels are also available on the Sirius satellite's Nordic beam as part of the Viasat package. Public Broadcasting of Latvia (since 2013) Since 2013, LTV has come under the umbrella of Public Broadcasting of Latvia (, LSM) along with Radio Latvia, as part of the unification process of both public broadcasters. LTV and Radio Latvia now share one news portal, LSM.lv, and an online streaming service (REplay.lv), with content from both broadcasters. LTV changed its aspect ratio from 4:3 to 16:9 in 2013. Selected programming such as live broadcast of a staging of The Nutcracker by the Latvian National Opera on LTV1 in 2012 and the matches of the IIHF World Championships on LTV7 (2018–present), were shown in HD. In 2019 a full switch to HDTV broadcasts was announced for 2021 or 2022, although delayed in previous years due to financial constraints. After upgrading their broadcasting technology, both TV channels and content on the REplay.lv and LSM began a gradual switch to Full HD (1080p) on 19 May 2021 for cable and online broadcasts (the switch for free terrestrial operators is scheduled for 2022). The LTV News Service programs (Panorāma etc.) marked their switch to 1080p on August 30 by unveiling a new studio
