This week I will be chairing a session on advances in sound, vision and control at Future Vision, the annual DTG Summit. I will be asking whether the current technical quality of broadcast television is good enough. I am interested to hear your views. We regularly report advances and innovations but many traditional broadcasters may be falling behind the technical quality of what can be delivered online and enjoyed at home. Four out of ten homes in the United Kingdom have a 4K ultra-high-definition television. Yet it is worth considering that more than one in ten homes are not online.
