An output method is changed optimally in response to a difference of a device connected to an output device and a combination of output media streams, and user's convenience is improved. Each of media state sensing unit 15, 25, 35, 45 for sensing a state of a media stream sends out a media state sensing signal to a control portion 90, and each of connection state sensing unit 62, 72, 82 for sensing a connection state between an outputting unit 51 and a providing device, which presents the media stream visually or audibly, sends out a connection state sensing signal to the control portion 90. The control portion 90 decides an output state based on priority output information 931, which specifies a preferential output state of the media stream, the media state sensing signal, and the connection state sensing signal, and then the outputting unit 51 outputs the media stream to the providing device.
