PROBLEM TO BE SOLVED: To provide a digital broadcast receiver capable of superimposing subtitle information for live broadcasting on video information at a time difference wherein unnaturalness is not felt. SOLUTION: Under the control of a CPU 7, a TUN 1 receives the digital broadcast of live broadcasting, a TSDMX 3 classifies received transport signals in each packet ID and separates video information, sound information and subtitle information from the transport signal of each packet ID, an STCCTL 11 delays decoding processing timing of the video information and the sound information, and then a mixer 10 makes the superimposed display timing of the subtitle information be coincident with that of the video information.
