TV Licensing - Live TV and how you watch it: "If the programme is being shown on live TV, you need a TV Licence to watch or record it. If the device or technology you’re using to watch the programme causes a delay between when the programme was shown and when you watch it, you’re still receiving live TV.
‘Live TV’ means any programme you watch or record at the same time as it’s being shown on TV or an online TV service.
If you only ever watch ‘on demand’ programmes, you don’t need a TV Licence.
On demand includes catch-up TV, streaming or downloading programmes after they’ve been shown on live TV, or programmes available online before being shown on TV." 'via Blog this'
