It's an immutable law: cellphones must keep getting smaller until the risk of swallowing them is too great. Well it stands to reason that smaller phones require smaller components, which is why Philips has just downsized their DVB-H chip once again. This new chip, called the BGT215, measures a mere 7 x 7-millimeters- practically invisible compared to its 15 x 26 predecessor. The Philips Customer Development Kit will help get this terrestrial DTV chip to market faster, and upgradable firmware means new services can be programmed onto the chip after it ships, which could be anytime after March.
