Abstract

An adapter device communicates with a sink device and a source device using first and second communication schemes, respectively. The adapter device includes: a transceiver receiving a state read request by detecting that a serial data line connected between the adapter device and the sink device is driven to a low level when a serial clock line connected therebetween is at a high level, and drive the serial data line to the low level and drive the serial clock line to a low level; a transmitter transmitting the state read request to the source device after the serial clock line is driven to the low level; and a receiver receiving a state read signal to read data of a state register in the sink device from the source device, wherein the transceiver transmits the state read signal to the sink device via the serial data line.
