Abstract
A television signal receiving apparatus which can read program information relevant to a television program from an optical disk medium, interlocked with the television program and can reproduce and display the read program information. Program information (broadcasting information including program names, broadcasting channel names and broadcasting dates and times and appendant information relevant to the contents of the programs) relevant to the television programs to be displayed by the television receiver/display is recorded in the optical disk medium. When a user instructs a display of the program information by the selection and decision input unit, the television control unit transmits the display request and time information from the clock apparatus to the control unit of the optical disk unit. The control unit makes the appendant information to be reproduced from the optical disk medium, by using the broadcasting channel name and the time information as retrieval information. The appendant information is sent to the television receiver/display through the interface and is displayed in a picture and sound.
