To improve operability in data broadcasting.
The data broadcast transmitted from a broadcasting station, etc., is reproduced and displayed on a display means 140. At this point, a pointer for indicating a prescribed position on a display screen is displayed according to a pointer control means 170. An instruction input means 150 performs an instruction of the coordinate of a moving destination of the pointer or instructions of 'decision' and 'return'. A coordinate information generating means 160 calculates a coordinate for displaying the pointer to generate coordinate information and transmits the information to the means 170. The means 170 moves the pointer to a prescribed position on the basis of the coordinate information, and searches a component corresponding to the displayed position of the pointer. Subsequently, an event defined by the BML(Broadcast Markup Language) standards set in the searched component is started by referencing the instruction information.
