A video display apparatus includes a reception unit configured to receive a plurality of sequence of video signals output from a plurality of cameras, a storage unit configured to store the plurality of sequence of video signals received by the reception unit, a display unit configured to include the first and second display areas, and a control unit. The control unit selectively and time-divisionally displays the plurality of sequence of video signals received by the reception unit on the first display area, and along with the display operation, selectively reads out from the storage unit a non-displayed section of the plurality of sequence of video signals which have been received by the reception unit, and displays the readout section on the second display area.

Video display apparatus

An image transmission apparatus and method for use with at least two transmission paths having different transmission rates from one another. The image transmission apparatus comprises an image input for receiving an image signal, a coding processing unit for encoding the image signal, a protocol control unit for packetizing the data encoded by the coding processing unit to generate data packets for transmission, and a transmission unit for transmitting the data packets. The protocol control unit has at least one timer processing unit which controls a data packet transmission interval individually corresponding to the transmission rates of the respective transmission paths based on data packet discard ratio information from the transmission paths.
