PROBLEM TO BE SOLVED: To enable the rate of magnification and reduction of a picture to be freely set without enlarging a scale of hardware by making display magnification control information, which corresponds to stipulation control information stipulating magnification and reduction of the picture in advance, arbitrarily variable in response to an external operation, using an LSI picture magnification and reduction processing part in common and executing magnification and reduction of the picture. SOLUTION: A magnification and reduction processing part 18 executes magnification or reduction of a digital video signal which is outputted from an MPEG decoder part 15 on the basis of an execution command automatically preset in a parameter set part 17 by its attribute information. A block which consists of the magnification and reduction processing part 18, the MPEG decoder part 15, a format information extract part 16, and the parameter set part 17 is turned into LSI. A control part 21 sets its own parameter for the parameter set part 17, in accordance with every kind of operation inputs from an operation input part 33. A function of change in a picture display condition can also be improved. |
