Re: 4k
There is not yet, but should be, so much more to 4k than the extra pixels, which, let's face it, are redundant to a lot of people a lot of the time. Much more noticeable benefits could be achieved by tacking on higher frame rates (less juddery/smeary motion), higher contrast (brighter whites/deeper blacks) and a wider range of colours. The BBC is able to look at this sort of thing from the point of view of the broadcasters, e.g. by developing systems which are not radically incompatible with how programmes are made at the moment (reducing production/infrastructure costs) and promoting universal standards (opening up the broadcast equipment market and hence also reducing costs).
