Abstract
A television receiver in which addresses are assigned to functional boards provided with different functional circuits such as teletext demodulators and satellite broadcast wave receivers, to identify each functional circuit, address data for specifying a functional circuit is sent out from a microcomputer, and a response signal from the functional circuit is read out by the microcomputer to judge the presence or absence of the functional board having the specified functional circuit, thereby automatically determining whether the functional board is to be controlled.
