The button group includes a change-over button and other button, such as volume button, power button. The input control circuit processes the signal coming from the button group and produces an output signal. The central processor member includes a central processor, ROM and RAM, program that the central processor runs and attention information data are stored in the ROM in advance. When a user pushes the change-over button, the central processor can cut off the audio input, at the same time, the central processor processes the attention information data and converts it into video signal to be outputting; the user pushes the change-over button again, audio signal will output again, and the central processor processes stops processing the attention information data.
