Abstract
A signal processing apparatus that enables while a significant video signal is not being output, a stream that is decoded to a black picture signal is output along with a base band signal that causes a block picture to be displayed. The signal is reproduced, as an MPEG stream. The MPEG stream is input to a first input terminal of a switch. The MPEG stream is supplied to a black stream generating circuit. A non-signal detector detects a non-signal state of the stream. In a non-signal period, a second input terminal of the switch is selected. A stream generator generates a black stream that causes a black screen to be displayed, which is input to the second input terminal of the switch, and is obtained from a stream output terminal through a switch.
