Abstract
Abstract Disclosed is a method and apparatus for selectively distributing on a multiple channel television system information previously transmitted and received in the Baudot code. The transmitted information is encoded into a sequence of Baudot characters to include a combination of figure shift and/or letter shift characters which identifies the category or type of information contained in the sequence. Upon receipt, the sequence is decoded to determine the category of information contained therein and then the information is applied to one of a plurality of storage areas in memory, with the particular storage area selected being dependent upon the determination of the information category. After an information sequence has been received, decoded and stored in one of the storage areas, it is then applied to one or more selected channels of the multiple channel television system for display on television receivers tuned to those selected channels. Control circuitry is provided for selectively applying information from any of the storage areas in memory to any of the channels of the multiple channel television system.
