Abstract:
Transmitting a bidirectional, virtual differential signal in addition to other differential signals over physical communication channels. Thus, four signal lines can provide three differential signals, where the virtual differential signal is bidirectional. The virtual differential signal can be provided over one or more of the other physical communication channels. Additional configurations allow for providing a bidirectional DC power supply. Additional configurations allow for providing DC power in addition to data over a reduced number of lines. Selective switching of signal lines can allow backward and forward interoperability with other standard interfaces.
