Channel 4 will launch its new digital hub on Monday, bringing together its linear and online content.
All 4, as the hub is known, will replace 4OD and will be divided into three sections: On Demand, Now and On Soon.
On Demand will offer users the ability to catch up on recent programmes, and will also host Channel 4 box sets.
The Now section will show live broadcasts from Channel 4's linear television, as well as exclusive Original Shorts. The Shorts will include six-part series Total Recast, made by Rumpus Media, which sees filmmaker Simon Birch remake film classics in 90 seconds with a cast pulled from the British high street.
On Soon will offer exclusive previews, including a first look at the new series of Made in Chelsea, ahead of their linear scheduling, while letting users set reminders for upcoming programmes.
"We're beginning to redefine the category," said Richard Davidson-Houston, Head of All 4 and Digital Content.
"All 4 is a new kind of channel with an unrivalled content offering. Where else can you find, whenever you want - for free ×£lassic box sets, catch up TV, live TV channels, original short programmes, TV premieres and bonus content for your favourite shows? Nowhere else. All 4 is unique."
Registered users will benefit from an increasingly personalised service, in a move that recognises the change in viewing behaviour, particularly among 16 to 35 year olds.
All 4 content will be optimised to play on mobile via 3G and 4G, and will work on PCs, iPods and iPads, with a roll out to other services throughout 2015.
