Concept of DTV---Is digital TV sound better?

Digital TV sound uses a newer technology than the Nicam Stereo sound available with analogue TV. However, the technology does not provide any more channels of sound, you still only have two. It's unlikely you will be able to hear the difference between the two systems. Further, Nicam and Digital TV sound provide near-CD quality sound, i.e. sound quality approaching that of a Compact Disc recording, in other words "not as good as" CD quality. Some retailers are advertising that Sky provides CD-quality sound. This is untrue.

Again, digital TV in other countries will use different technology to bring a more advanced sound system. For example, where we use 2 sound channels encoded with MPEG audio, the USA will use 5+1 channels provided by the Dolby Digital system. The BBC say there simply isn't enough bandwidth to be able to provide Dolby Digital in the UK.
