<p>PURPOSE:To execute a thinned-out transmission smoothely when position information is transmitted by a low speed transmission line by adding position information of lines or rows to image information of respective lines and respective rows at the transmitting side, identifying position at the receiving side and displaying received image information to the identified position. CONSTITUTION:At the transmitting side, a line address signal D of even lines is generated, the address signal D of respective lines is added as position information G and image information of line unit is sent. At the receiving side, position information G is detected at a line address detecting circuit 3, a line address signal (d) is outputted from a line address generating circuit 7, a row address signal (e) is outputted from a row address generating circuit 8 and image information of received line unit is written in a memory 1. From a display address generating circuit 10, an address signal (h) and a row address signal (i) are successively outputted, read image information including odd lines, where image information is not written at a display part 12, is added through an AND circuit 11 and reproducing screen can be obtained.</p> |
