RTÉ2
RTÉ2 is an Irish free-to-air television channel operated by public service broadcaster RTÉ. It was launched in 1978 as the Republic of Ireland's second television channel. History In the 1970s, the Irish government considered three options for the introduction of a second television service: the re-transmission of BBC1 Northern Ireland; authorization of an independent commercial service; or charging RTÉ with the establishment of a second national channel. It was the last of these that was finally chosen. The channel—only the second in the Republic—began transmissions at 20:00 on 2 November 1978, opening with a broadcast of a gala ceremony from Cork Opera House. Owing to a technical error, audio from BBC2 was played during the countdown instead of the proper soundtrack.

The number "1080" refers to the number of horizontal lines on the screen. The "i" is an abbreviation for "interlaced"; this indicates that only the even lines, then the odd lines of each frame (each image called a video field) are drawn alternately, so that only half the number of actual image frames are used to produce video. A related display resolution is 1080p, which also has 1080 lines of resolution; the "p" refers to progressive scan, which indicates that the lines of resolution for each frame are "drawn" on the screen in sequence. The term assumes a widescreen aspect ratio of 16:9 (a rectangular TV that is wider than it is tall), so the 1080 lines of vertical resolution implies 1920 columns of horizontal resolution, or 1920 pixels × 1080 lines. A 1920 pixels × 1080 lines screen has a total of 2.1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
