PROBLEM TO BE SOLVED: To quantitatively judge a present line situation by displaying an execution speed at the present point of time in an equipment and on a screen. SOLUTION: A microcomputer 1 transmits data with an external radio transmission equipment with a data signal and a control signal and supplies received compression image data to an extension processing part 2. Besides, the execution speed is measured and execution speed data obtained as a result is supplied to an interpose display circuit 3. An extension processing part 2 extends inputted compression picture data and supplies an extended video signal to the interpose display circuit 3. The circuit 3 outputs a video obtained by interposition- displaying execution speed data from the microcomputer 1 on the video signal from the extension processing part 2 to an external monitor. Thus, the execution speed is displayed so that not only it is discriminated whether data transmission is executed or stopped but also the present line situation is quantitatively grasped by the execution speed. |
