SUPER HI VISION TELEVISION
This week on the World Service technology programme, Gareth takes a trip to the top of London's City Hall to witness the first live broadcast of Super HI vision.
Tipped by some as the future of broadcast technology, the television pictures are 16 times as clear as the latest high definition TVs with 22 channels of surround sound. But will the technology ever make it into your living room?
MONITORING POLIO IN KENYA
Mobile technology has been revolutionizing the way contagious diseases are monitored in sub-Saharan Africa. Doctors have been using a tool called EpiSurveyor, which can be downloaded onto PDAs or mobile phones, to log patients' symptoms and treatment.
