Confirming David's observations, I've followed up this exciting
possibility, and discussed the matter with some video and audio
compression "experts". Clark seems to be claiming an information
compression of 1000:1, which is astonishing, some might say unbelievable.
Compression techniques customed to audio, for example, can achieve better
than 2:1 (but only on audio), by preempting structures in the audio data
and explotiing them.
Some people have suggested that it seems ridiculous that he should even be
discussing the idea publically if, as he says, he does not yet have
sufficient patent protection. Of course this might be his way of
attracting financial attention. Finalising such an important patent is no
easy thing, and very expensive.
To quote the magician and sceptic Randy, "extraordinary claims require
extraordinary proof". Transmitting a few screen bar codes and music by
phone line to a shopping centre is not extraordinary. Demonstrating the
transmission of _any_ video and audio signals by phone line in the
presence of data transmission experts would be.
