The present invention separates a video stream from compressed multiplexed data using a transport decoding section ( 3 ) while receiving digital broadcast using an antenna ( 1 ), expands the video stream, and reproduces original video data and original audio data. At this time, when a mobile digital television ( 100 ) is open, the original video data is outputted to a main screen video output section ( 9 ). On the other hand, when the mobile digital television ( 100 ) is closed, the video stream is stored in a temporary storage section ( 11 ) and only an I picture is extracted from the video stream, decoded, and outputted to a sub-screen video output section ( 10 ).
