Its not a 32 bit YUV. A lot of color information throwen and they try to cheat the senses with lack of ability to act right. Unless British , German and Nordic people are not happy with HD channels and they want improvement when it is the best system at satellite and expensive.
16 megapixel - 48 megabyte story is interesting. BBC dont allow to air a scene shot by a cameraman at with least 50 megapixel and there is a backward quality worse than 30 years ago colors.
