Abstract
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.
