摘要： To provide an electronic apparatus capable of easily detecting a terminal that forms a loop connection state with a simplified configuration.A control unit counts the number of broadcast packet supplied from a switching hub to a communication unit within a predetermined time period and determines whether the number of packets exceeds a threshold value (ST2, ST3). If the number of packets exceeds the threshold value, the control unit determines that an abnormal connection state occurs, that is, a loop is detected and starts a process in which the control unit identifies a network terminal that forms the loop connection state (ST3, ST5). The control unit counts the number of broadcast packets that reach each of the network terminals, that is, broadcast packets input to each port of the switching hub. Thereafter, the control unit determines whether the network terminal that has received the number of packets exceeding the threshold value is present, that is, whether an abnormally connected terminal is present (ST5, ST6). If an abnormally connected terminal is present, the control unit displays a message indicating abnormal connection, the abnormally connected terminal, and a message prompting connection change (ST7).

摘要： [Object] To discriminate whether a cable in conformity with a conventional standard or a cable in conformity with a new standard is connected.[Solving Means] An HPD signal line (902) has, on an expanded HDMI sink apparatus (402) side circuit, a pull-up resistor (911) between the HPD signal line (902) and a voltage supply and a pull-down resistor (913) between the HPD signal line (902) and the ground, and a reserved line (903) has, on the expanded HDMI sink apparatus (402) side circuit, a pull-down resistor (914) between the reserved line (903) and a ground, and within a new HDMI cable (901), a pull-up resistor (912) between the reserved line (903) and a voltage supply of an expanded HDMI source apparatus (401). The expanded HDMI sink apparatus compares a voltage at a test point (19) on the reserved line (903) on the expanded HDMI sink apparatus (402) side with a reference voltage by using a voltage comparator (916).
