It is not limited to examples. For example, a new data conversion unit is installed in front of the superimposition unit 18, and the character size of the font image data acquired by the font data acquisition unit 112 is set to a size suitable for the display size of the external monitor 20 by the data conversion unit. Even in the case of conversion, it can be similarly implemented. Specifically, font image data having a character size suitable for the display size of the display unit 11 is stored in the memory 113, and font image data having a size suitable for the display size of the display unit 11 is stored by the font data acquisition unit 112. When acquired, the character size of the font image data may be converted into a size suitable for the display size of the external monitor 20 by a data conversion unit installed in the preceding stage of the superimposing unit 18. Note that if the font size of the font image data acquired by the font data acquisition unit 112 is larger than the display size of the external monitor 20, the acquired font image data may be thinned out according to this display size.

  In the above embodiment, the example in which the display content of the external monitor 20 matches the display content of the display unit 11 has been described. However, the display content of the external monitor 20 and the display content of the display unit 11 are different. It is also possible. This can be realized, for example, by changing request signals output from the external monitor processing unit 19 and the main body processing unit 110, respectively. The external monitor 20 can simultaneously display various information in addition to the program information.
