Sound and Vision

Available for over a year

Jay-Z, Alicia Keys, Madonna, Kanye West, and Rihanna are among the co-owners of Tidal, a new music streaming service launched this week. Can it go toe-to-toe with established players such as Spotify and Pandora? The major mobile technology companies are pinning their hopes on virtual reality – Louis Jebb, CEO of Immersiv.ly talks to us about the technology's potential for the news and media business. We attend a tribute to Alan Dower Blumlein, who first developed the process for sound recording in Stereo, along with other pioneering work in telecommunications, television, and radar. And, we ask, would you have a surveillance camera in your home to watch your family remotely? Presented by Rory Cellan-Jones, with special guest Kayleigh Bateman, Special Projects Editor at the magazine Computer Weekly.
