    摘要： A display device control system includes a first display device configured to include a first ultra-wideband (UWB) module and a first Bluetooth module, a second display device, and a remote controller configured to include an infrared (IR) module, a second UWB module, and a second Bluetooth module. The first display device and the remote controller are paired with each other. When the second display device includes a third UWB module and a third Bluetooth module, the third UWB module of the second display device senses the remote controller, the first display device and the remote controller are unpaired with each other, and the second display device and the remote controller are paired with each other.

    摘要： An information processing method for use in a receiver, the receiver unidirectionally receiving, from a transmitter using a first differential signal, pixel data of an uncompressed image of one screen during an effective video period representing a period from one vertical synchronization signal to the next vertical synchronization signal excluding horizontal blanking intervals and a vertical blanking interval, the method comprising the steps of:
    - receiving by Report Physical Address of CEC control protocol, from the transmitter, a notification indicating that the physical address of the transmitter designates a CEC-compliant device having a specified logical address, said specified logical address being indicative of a device type of the transmitter;
    - transmitting by a LAN sending circuit of said receiver, to the transmitter, a second differential signal representing transmission data different from the pixel data via differential transmission lines formed from a pair consisting of the reserved line and the hot plug detect line of an HDMI cable;
    - receiving, by a LAN signal receiving unit of the receiver), connected to the LAN sending circuit, an added signal comprising said second differential signal added to a third differential signal transmitted from the transmitter via the reserved line and the HPD line of the HDMI cable; and
    - subtracting, by a subtracting circuit of the receiver, said transmission data represented by the second differential signal from the signal received by the LAN signal receiving unit.
