A connection state display controller provided in a content processor comprising a display section capable of displaying various information, an input terminal capable of inputting a content signal having at least one of a sound signal and an image signal and a content processing section that processes the content signal to be input via the input terminal,
- wherein, when a signal processor having a content generating function for generating the content signal is provided as a transmitter, and a signal processor not having the content generating function but having a content transfer function for transferring the content signal is provided as a transfer device, the transmitter for transmitting the content signal is connected to the input terminal via the transfer device, the connection state display controller instructs the display section to display a connection state between the transmitter and the transfer device, the connection state display controller comprising:
- a connection information generating unit that recognizes the connection state to generate connection information including to-be-displayed device information for specifying the transmitter and the transfer device respectively;
- and
- a connection information display controlling unit that instructs the display section to display only the to-be-displayed device information for the transmitter, or instructs the display section to display the to-be-displayed device information for the transmitter and the to-be-displayed device information for the transfer device in different display forms.
