Abstract

A system including a broadcasting station which transmits many independent information packets to many receiving sets in succession. An information packet consists of a text, a classification code and a distinction code. Text is a sequence of words and symbols which may be converted into voice. Classification codes specify the substance of text, distinction code is annexed to each different text for distinguishing that type of text from other texts. A receiving set with registered classification codes selects and accumulates only necessary information packets by comparing the transmitted classification codes with stored codes. If the codes match, the text is stored so that the receiver can playback the voice information at a convenient later time.
