Signal relaying device and signal relaying method

Abstract

A signal relaying device applied to DisplayPort architecture is disclosed. The signal relaying device is coupled between a source device and a sink device and includes a receiving end, an arbiter and a transmitting end. The receiving end receives a request signal from the source device via the first auxiliary channel. The arbiter is coupled to the receiving end and receives the request signal. The transmitting end receives the request signal from the arbiter and transmits the request signal to the sink device via the second auxiliary channel. The sink device transmits a first configuration data to the transmitting end via the second auxiliary channel when receiving the request signal. The arbiter replaces the first configuration data with the second configuration data and transmits the second configuration data to the receiving end when receiving the first configuration data from the transmitting end.

Dependencies are inferred from the claim text.
