摘要： [Object] To provide an electronic apparatus capable of easily detecting a terminal that forms a loop connection state with a simplified configuration.[Solving Means] 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： ObjectTo transmit well a video signal of a desired bit rate within a transfer bit rate of a transfer path.Solving MeansA control unit 111 controls the operation of data compression units 121-1 through 121-n and switch unit 122. When the bit rate BR of a non-compressed video signal output from a codec 117 is within the transfer bit rate BR2 of an HDMI transfer path, the control unit 111 supplies the non-compressed video signal output from the codec 117 to the HDMI transmitting unit 102 as a video signal to be transmitted. On the other hand, when the bit rate BR1 is greater than the bit rate BR2, the control unit 111 selects a compression method that can be handled on the receiving side performs compression processing so that the bit rate BR1 becomes lower than the bit rate BR2, and supplies the compression video signal to the HDMI transmitting unit 102 as a video signal to be transmitted. Also, the control unit 111 transmits compression information (control information of the switch unit 122 and data compression units 121-1 through 121-n).
