ABSTRACT:
A video display apparatus includes a video data generator which generates video data of a plurality of still picture and a moving picture (graphic data) in an overlaid manner on the basis of still picture patterns, still picture character codes, moving picture character codes and etc. programmed in an external storage unit in advance. A microprocessor applies, in accordance with priority data for the still pictures and the moving picture and mode data both programmed in the external storage unit in advance, first priority data to the video data of the still picture characters and second priority data to the video data of the moving picture character, respectively. A priority encoder selects a still picture character or a moving picture character having the highest priority on the basis of the first and second priority data, and applies the number of that character to a decoder. The decoder outputs a gate control signal in accordance with the number. In response to the gate control signal, the video data of the character having the highest priority among the respective still picture characters and the moving picture character is outputted from a gate.
