Abstract
A television receiver includes a closed-caption signal demodulator, an existence-of-closed-caption-signal discriminator located upstream of the demodulator, and a character memory for supplying a simple character, meaning that a closed-caption signal exists in an image signal, onto the screen of the television receiver. This simple character is supplied to the screen upon receipt of a discrimination signal, indicating that a closed-caption signal, exists in an image signal from the existence-of-closed-caption-signal discriminator. With this television receiver, the user can recognize, at a time prior to actual selection of closed-caption signal demodulation, whether or not a closed-caption signal exists, in an image signal.
