PROBLEM TO BE SOLVED: To provide a means that outputs both moving picture signals of analog and digital broadcast programs to display devices with different formats. SOLUTION: The moving picture format converter of this invention is applied to a digital broadcast receiver provided with a horizontal/vertical size conversion means that magnifies or reduces an input moving picture signal at an optional magnification in horizontal/vertical direction, with a data buffer that stores a data quantity of a horizontal size of the input moving picture signal, with a means that selects each input signal, and with a means that selects a display output signal, allows the selection means to select the signal in a way of minimizing the data quantity received by the data buffer and the vertical size conversion means depending on an image format conversion operating mode, and allows the data buffer 23(24) to selectively act like a write buffer 231 and a read buffer 232 for access to a field memory to delay the input signal by a prescribed time or like one line buffer through the cascade connection of them.
