Abstract
On a display (100) end, maker codes and device codes are read from all STBs (110˜112) connected to the display (100) to create a connected-device table. When a user presses a button on a remote controller, the display receives a remote control code outputted from the remote controller, searches the connected-device table for a maker code and a device code that match the maker code and the device code included in the remote control code, controls a selector (105) so that a reception interface that is connected to an STB whose maker code and device code match those included in the remote control code is connected to a display section (102), thereby to display AV data transmitted from the STB on the display section (102).
