ABSTRACT:
If a device non-compatible with CEC is contained in an input path when a display apparatus is HDMI-connected hierarchically to a plurality of external devices, an external device which has transmitted <Active Source> is selected as an operation object device. A TV (100) is HDMI-connected hierarchically to external devices (an AV amplifier (20a), recorders (10a,10c), a DVD player (10b)) in a tree shape. The TV (100) receives <Active Source> indicating an active state capable of video output from the DVD player (10b) and transmits <Set Stream Path> for switching the input path to the DVD player (10b). When a device non-compatible with CEC (AV amplifier (20a)) is contained in the input path which transmits <Set Stream Path>, the TV (100) selects the DVD player (10b) specified <Active Source> as an operation object device.
