channel 1 in the United Kingdom

- fredoralive 11y agoFor the sort of "channels" discussed in the article, the UK hasn't used a channel 1[1] for TV since 1985, as VHF was only used for the older 405 line TV system. Newer 625 line analogue TV[2] was and digital terrestrial TV is UHF only in the UK, and UHF channels are numbered from 21. For convenience most TVs mapped the channels onto buttons 1/2/3/4 for analogue but behind the scenes they would be something like channels 27/29/31/33. Modern DTT channel numbers are also completely separate from what radio channel each TV channel is actually being carried on. [1] The definition of "channel 1" is different in different countries. https://en.wikipedia.org/wiki/Television_channel_frequencies https://en.wikipedia.org/wiki/Television_channel_frequencies [2] BBC2 was UHF / 625 only at launch in 1964, BBC1 and ITV started in 1969 when they introduced colour. Analogue ended late 2012.

- teh_klev 11y agoNot criticising your facts but [2] would be better rewritten as: >BBC1 and ITV started in 1969 when they introduced colour. => >BBC1 and ITV started broadcasting on UHF/625 in 1969 when they introduced colour. Also, my own 2c, BBC1 and ITV continued broadcasting on VHF/405 simultaneously until 1985.
