  • Publication number: 20190158778
    Abstract: A video signal switching apparatus includes a signal selection device which selectively outputs received multiple video signals to its first and second output ports; and a signal switching device, which includes first and second signal conversion devices coupled to the first and second output ports, and a switch which selectively couples the first or second signal conversion device to a switch output. The first signal conversion device receives a first video signal having a first format from the first output port and converts it to a first converted video signal having a second format. While the switch selectively couples the first converted video signal from the first signal conversion device to the switching output, the second signal conversion device receives a second video signal having a first format from the second output port and converts it to a second converted video signal having the second signal format.

  • Patent number: 9900050
    Abstract: A communication verification system is provided. The communication verification system includes a local transmitting-end unit, a remote receiving-end unit, and a repeater device. The local transmitting-end unit is set to a first computing mode and outputs an initial value. The remote receiving-end unit is set to a second computing mode. The repeater device receives the initial value from the local transmitting-end unit and outputs an initial value to the remote receiving-end unit according to the second computing mode. The repeater device receives and stores a computation result from the remote receiving-end unit, and then outputs a confirmation signal to the local transmitting-end unit according to the first computing mode. The repeater device outputs the computation result to the local transmitting-end unit for verification when the repeater device receives a query signal from the local transmitting-end unit.
