What is HD?

High-definition, or HD, is the term used to describe a form of TV broadcasting which provides extremely high quality picture and sound.  A better TV that is HD-ready must be used in order to watch programmes broadcast in HD quality.  Not everything is available in high definition, but different channels and providers are usually very focused on advertising which content can be in the superior format, so it's easy to find out which channels and programmes have the HD treatment.
