In 2009, Skype 4.0 was released, featuring full-screen high-quality video calling.

Video and an innovative user interface are also employed to spectacular effect in "Johnny Mnemonic," the first interactive title to use full-screen video so compellingly.

"You can use this technology to scale up to full-screen video," said Pat Gelsinger, Intel's vice president and general manager of desktop products.

Because it always renders in overlay, full-screen video to TV-out is always activated.

The service offers full-screen video through a Flash-based interface, building on the 55 shows already podcasted or released online.

It's the full-screen video calls that make the iPad version an essential, though.

Digital Video Interactive supports full-screen video with 24-bit colour, and 1,024 by 768 pixel resolution, running at 30 frames per second.

It reacts slowly, it feels insubstantial and poorly put together and occasionally becomes uncomfortably hot when running heavy tasks such as full-screen video.

The North American releases feature full-screen video and stereo sound in both English and Spanish.

You can also change the size and location of the picture windows or simply watch full-screen video.
