Quality

•Unprecedented level of sharpness and definition in picture quality
•Reduction in interference
•Digital quality sound
However…
•We have to invest in hardware (LCD/plasma) where the digital signal is decoded. Without this we only notice a slight improvement
•Compression of digital images which is necessary to multiplex the existing bandwiths might also effect the quality of the image
•They need to turn off “analogue” signal before there is enough bandwidth to provide HDTV more than a few channels
