Method of transmitting information relating to racing and receiver for implementing this method

摘要

The method consists in modulating a sub-carrier SP sometimes by the speech signal Sp and sometimes by the data Sd and in transmitting this sub-carrier through an FM radio-broadcast channel. On reception, the sub-carrier is extracted and demodulated, the real-time commentary is restored and the data are displayed. Application, in particular, to horse racing. <IMAGE>
