Abstract:
1. A method for transmitting/receiving image data in a mobile communication system, in which image data are classified into two types of image data, a first type of image data corresponding to entire-image data in a current time period, a second type of image data being image data representing a difference between previous time-period image data and current time-period image data, the method comprising the steps of: transmitting image data from a transmission side to a reception side; notifying the transmission side of an error when it is detected on the reception side that received image data has an error; receiving, on the transmission side, notification of error occurrence, generating the first type of image data, and transmitting the generated first type of image data to the reception side; discarding the second type of image data prior to decoding, when the second type of image data is received at the reception side after the error occurrence and before the reception side receives the generated first type of image data from the transmission side; and receiving, on the reception side, the generated first type of image data from the transmission side, and decoding the received first type of image data.
