DISPLAY SYSTEM AND DISPLAY DEVICE

摘要

If a device non-compatible with CEC is contained in an input path when a display device 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.
