Channel 4+1 launches today
Channel 4 has become the first terrestrial channel to launch another channel with the same programmes on a one-hour delay.
Called Channel 4+1 the schedule will mirror Channel 4's exactly, with a one-hour time delay in case someone misses a particular show.
The formula is already used for the digital channel E4 and More4, as well as ITV2 and Sky One.
Channel 4 noted: "You'll never miss your favourite programme again."
The new offering is available on Freeview, as well as other digital services and will correlate with a changing of channel numbers for Channel 4's network.
On Sky, +1 will be 135, E4 will be 136, followed by E4+1 on 137 and More4 and More4+1 on 138 and 139 respectively.
The analogue signal will begin to be switched off in October as the nation begins to convert to digital.
All viewers will be watching digital by the end of 2012, when the analogue signal will be stopped completely.
