Wired broadcasting in Great Britain

In densely populated areas the number and power of television transmitters in the VHF band are beginning to pose a serious problem of mutual interference. In view of this, and of the need to leave the radio spectrum free for communication circuits for which it is a necessity, it is pertinent at this time to review the possibilities of systems designed for broadcasting by wire. What has been achieved in Great Britain, where wired broadcasting is seriously competing with conventional systems, is described. The requirements, and advantages, of a wired network are examined, and a comparison is made with CATV systems.
