a) is for transmission, and a monitor receiver (not shown) is connected to the input / output circuit (14b). Further, transmission is performed in a state where the edited still image packet is stored in the memory device (1A). When the workstation (2) first issues a transmission instruction, the first still image of the packet is transferred to the input / output circuit (14a) for transmission, and the second still image is transmitted to the input / output circuit (14b). And displayed on the monitor receiver. Next, in this state, when a transmission instruction is issued again from the workstation (2), the second still image of the packet is transferred to the input / output circuit (14a), and the packet is transmitted. The data is transferred to the output circuit (14b) and displayed on the monitor receiver.

The still images of the packets edited in this way are sequentially transmitted. In this case, a still image to be transmitted next is displayed on the monitor receiver, and when the next still image is unnecessary after seeing this display, the next still image is transmitted by an instruction from the workstation (2). Processing such as deletion can also be performed.
