The present disclosure relates to a system and method for synchronous video display on at least one display. The method may comprises receiving a channel of video signal from each data acquisition port of a plurality of data acquisition ports during a time interval, each channel of video signal comprising a plurality of video frames captured during the time interval. The method may also comprises assigning a count value for each video frame of the channel of video signal as synchronization information for each video frame of the channel of video signal to form a pool of video frames each corresponding to a count value. The method may further comprises selecting video frames with the same count value from the pool of video frames as synchronized video frames, and transmitting, through the plurality of output ports, the synchronized video frames for synchronous display on the at least one display.

An image receiving terminal includes a communicator and one or more processors. An elapsed time is a time period from a time point at which a vertical synchronization signal is generated to a time point at which a specific packet is received by the communicator. The processor sets a determination reference time on the basis of the plurality of measured elapsed times. The processor determines whether the communication channel which is used by the communicator is to be switched to another communication channel on the basis of the set determination reference time and the elapsed time measured after the determination reference time has been set. The processor controls switching of the communication channel which is used by the communicator on the basis of the result of determination of the communication channel.

An X-ray imaging device includes a first wireless communication module coupled to a first set of antennas; a second wireless communication module coupled to a second set of antennas; and a controller that is coupled to the first wireless communication module and the second wireless communication module. The controller is configured to receive a first value for a wireless performance metric for the first wireless communication module while the X-ray imaging device, receive a second value for the wireless performance metric for the second wireless communication module while the X-ray imaging device, based on the first value and the second value, determine a first wireless communication function to be performed by the first wireless communication module, and cause the first wireless communication module to perform the first wireless communication function.

An embodiment of the present invention includes a technique to provide multiple focus controls. First and second focus managers manage first and second focus owners, respectively. The first and second focus owners correspond to components of media planes displayable on at least one of a plurality of output display devices. The first and second focus managers associate first and second key events generated by first and second input devices, respectively, to the respective first and second focus owners. A router has a routing table that stores information of association between first and second connections and the first and second focus managers, respectively. The router routes one of the first and second key events originating from the respective connection to a corresponding focus manager using the routing table.
