ABSTRACT
The term “high-definition television” has been coined to distinguish it from the service of television signals now featured by the B.B.C. using a Baird thirty-line mirror-drum transmitter, as described fully in another section of the book. It relates to the number of lines into which the television picture is dissected, the greater the number of lines the greater being the degree of definition, or alternatively the greater the amount of intimate detail which can be made intelligible to the eyes of those looking in at the received pictures.
