`ABSTRACT
`
`The builtiin components in the portablertype apparatus each
`operate on power from the power supply (PS) unit having a
`built-in battery. The video data decoded by the video
`decoder (MPEG—DEC) and the sub—picture data decoded by
`the sub—piclure decoder (Sub—l’icture—DEC) are mixed with
`the video mixer (MIX) and then output
`to a display unit
`(DISP). An audio signal decoded by the audio decoder
`(Audio-DEC) is output from the speaker (SP).
