Many of us have used the BBC iPlayer to watch live TV when away from home or when someone else is watching the main TV (The Euros being a prime example).

Yesterday, the BBC launched a fascinating addition to its live service. Called Live Restart, it enables live viewers the ability to rewind up to two hours through content, or just to click to the beginning of the current programme. Missed the goal or watch the 100m final again? Just rewind, watch again, then fast forward to the present.

Live Restart is another example of how people are able to more easily control the viewing experience. And with such ease of control, some of the distinctions people make between live and non-linear video are likely to continue to decline.

It will be interesting to see in what situations people will use the service, and with which other kinds of content. Sport is an obvious example, such as during the rest of the European Championships and during Wimbledon and the Olympics.

It will also be interesting to see if this drives up PVR purchase rather than down. Having had a taste of time-shifted TV on a computer, non-PVR owners are likely to want to replicate the experience onto the TV and across other TV channels.
