The new version will run in parallel with the existing offering for the next few weeks. The update comes as requests for TV programmes hit 700,000 per day in April.
As well as integrating on-demand radio with the iPlayer, the service will feature a larger playback screen, a TV schedule that allows users to plan their viewing over the coming days, and, a "last played" facility to allow viewers to resume watching a programme where they left off.
Eric Huggers, the BBC's group controller of future media and technology, said consumers are now able to experience "the full range of BBC content in a more accessible way".
Huggers added: "The full integration with iPlayer is a natural evolution for the audio service and an exciting step for audiences." The iPlayer will soon be available on other platforms, including the Apple iPhone and iPod touch, plus the Nintendo Wii. Earlier this year, it was launched via the Virgin Media cable platform.
The BBC also revealed there have been 100 million requests to view TV programmes since the iPlayer launch last December.
