Abstract
A multi-media communication apparatus has functions of receiving/transmitting images, audio signals, code data and the like. A detection unit detects an error in an image signal received from a communication partner's terminal. A transmission unit transmits a picture renewal request command to the partner's terminal based on a detection signal from the detection unit to automatically recover a disturbance of the received image. If the received image becomes discontinuous or disturbed at time of frame synchronization error or the like, the image immediately before the occurrence of disturbance or a different image, e.g., an image for informing the operator of the apparatus condition, is displayed in place of the disturbed image. The operator can be informed of the occurrence of a communication error through the same media as those used for communication before the occurrence of the error.
