Apparatus for receiving broadcast data, method for displaying broadcast program, and computer program

A method for displaying a data broadcast program, comprising:

• a receiving step of receiving image data of the image of an object and size information relating to the object, transmitted through data broadcasting;
• an input step of inputting screen information relating to a display screen of display means;
• a scaling step of determining a scale factor of the object image based on the screen information input in the input step and the size information received in the receiving step so that the object image is displayed on the display means at a predetermined size;
• and
• a display control step for controlling the display means to display the object image expanded or contracted at the scale factor determined in the scaling step.

A computer program for displaying a data broadcast program, comprising:

• a receiving step of receiving image data of the image of an object and size information relating to the object, transmitted through data broadcasting;
• an input step of inputting screen information relating to a display screen of display means;
• a scaling step of determining a scale factor of the object image based on the screen information input in the input step and the size information received in the receiving step so that the object image is displayed on the display means at a predetermined size;
• and
• a display control step for controlling the display means to display the object image expanded or contracted at the scale factor determined in the scaling step.

An apparatus for receiving broadcast data, comprising:

• receiving means for receiving broadcast image data transmitted through data broadcasting;
• display control means for synthesizing the broadcast image data received by the receiving means and user image data registered beforehand and for causing display means to display the synthesized data;
• and
• scaling means for scaling the broadcast image data and the user image data so that the broadcast image data, the user image data, and the display screen of the display means coincide with each other in scale,
• wherein the display control means synthesizes the broadcast image data and the user image data scaled by the scaling means, and causes the display means to display the synthesized data.
