BBC invent HD bandwidth transmission system

The BBC’s Research and Development team have invented a new transmission method for delivering twice the bandwidth that can currently be delivered via each DTT frequency. In very over-simplified terms, 2 signals are sent on the same frequency in slightly different directions and at slightly different times. Don’t expect HD just yet, though: the “spatially multiplexing” requires new transmitters to be built and you’ll need a new aerial and box. Still, sounds exciting, doesn’t it.
