Editing BBC Two (section)

===Technological advancements===
Unlike [[BBC1]] and ITV, BBC2 was broadcast only on the [[625-line]] [[Ultra high frequency|UHF]] system, so was not available to viewers still using sets only capable of receiving the [[405-line television system|405-line]] [[Very high frequency|VHF]] system. This created a market for dual standard receivers which could switch between the two systems. Set manufacturers increased production of UHF sets in anticipation of a large market demand for the new BBC2, but the market did not materialise.{{citation needed|date=July 2022}}

The early technical problems, which included being unable to transmit US-recorded videotapes due to a lack of [[Television standards conversion|system conversion]] from the US [[NTSC]] system, were resolved by a committee headed by [[James Redmond (broadcaster)|James Redmond]], although this problem was not unique to BBC2.

On 1 July 1967, during the [[1967 Wimbledon Championships|Wimbledon Championships]], BBC2 became the first channel in Europe to begin regular broadcasts in colour, using the [[PAL]] system.<ref>[http://www.screenonline.org.uk/tv/technology/technology8.html TV Technology 8.

BBC1 and ITV simultaneously introduced PAL colour on UHF on 15 November 1969, although they both had broadcast some programmes in colour "unofficially" since September 1969.

In 1979, the station's adoption of the first computer-generated channel identification (ident) in Britain, with its use of the [[BBC Two 'Computer Generated 2' ident|double striped, orange '2' logo]], heralded the start of computer-generated logos. The ident, created in-house by BBC engineers, lasted until March 1986. 

As the [[Digital terrestrial television in the United Kingdom#Digital switchover|switch to digital-only terrestrial transmission]] progressed, BBC Two was (in each region in turn) the first [[Analogue terrestrial television in the United Kingdom|analogue TV channel]] to be replaced with the BBC multiplex, at first four, then two weeks ahead of the other four channels. This was required for those relay transmitters that had no current [[Freeview (UK)|Freeview]] service giving viewers time to purchase the equipment unless they had already selected a satellite or cable service. The last region for BBC Two to end on analogue terrestrial television was [[Northern Ireland]] on 10 October 2012.

At the 2012 [[Edinburgh International Television Festival]], BBC Two was named "Terrestrial Channel of the Year".<ref>[https://www.bbc.co.uk/news/entertainment-arts-19376264  "BBC Two wins terrestrial channel of the year"]. BBC News, 24 August 2012. Retrieved 28 June 2013.</ref>

A [[high-definition television|high-definition]] simulcast of BBC Two began broadcasting on 26 March 2013, replacing the standalone [[BBC HD]] channel.<ref>{{cite web |url=http://www.whathifi.com/news/bbc-two-hd-channel-to-launch-on-march-26 |work=What Hi-Fi |title=BBC Two HD channel goes live, replacing BBC HD |access-date=9 July 2013 |date=26 March 2013 |archive-url=https://web.archive.org/web/20130615062146/http://www.whathifi.com/news/bbc-two-hd-channel-to-launch-on-march-26 |archive-date=15 June 2013 |url-status=dead}}</ref> {{As of|2018|11|29}}, there are three variations of BBC Two HD (Wales, Northern Ireland, and England).<ref>{{cite web |title=Changes to our HD portfolio and satellite transponders |url=https://www.bbc.co.uk/blogs/aboutthebbc/entries/7a69712a-5942-4792-af89-99f73c731bbd |work=About the BBC Blog |access-date=29 November 2018 |date=16 October 2018}}</ref>
