HDTV-putting you in the picture

Interest is now starting to be expressed in larger television displays, which fill more of the observer's field of view, and hence increase their level of involvement in the programme. Unfortunately, these large screens reveal only too clearly the restricted resolution and visible line structure of today's television standards. If the true benefit of large-screen displays is to be obtained, then the television standard itself must be changed to allow a higher definition to be achieved in the final image. Hence the term 'high-definition television', or HDTV for short, has come to imply a television standard capable of being satisfactorily displayed in this way. The author investigates recent research of development into HDTV and discusses the desire for a unique, worldwide standard for HDTV programme production.<
