19. Technology on a Chip

20. Component Design  The challenge – a step change whist maintaining user expectations  Products in the hand-held/mobile space have always been constrained by the battery, the digital STB has evolved unconstrained into a power hungry system. Existing products exhibit very little difference in power consumption between “on” and “standby” modes, typically as little as 1W-2W difference (<5%)  The Opportunity  With approximately 25M households in Great Britain (source: NSO 2006 25.26M) and an 85% penetration rate for set-top-box consuming on average 300KW/hr per year, the total power consumed is ~6.4TWh/year. A 50% power saving equates to 3.2TWh/year, or 2 million tons of CO 2 ! 20
