Abstract
A method and apparatus for controlling intra-refreshing in a video telephone communication system are provided. A reception apparatus checks a sequence number and a CRC for received video packet data to detect presence of a packet loss, decodes the received video data to check frame type information, generates a control signal for requesting intra-refreshing in accordance with the checked frame type information and the sequence number, and transmits the generated control signal for requesting intra-refreshing to a transmission apparatus. The transmission apparatus determines whether a control signal for requesting transmission of an I-frame obtained by compressing an independent image is received from the reception apparatus, checks frame type information and a sequence number of video data being compressed, determines whether to transmit a temporary I-frame corresponding to the received control signal or to transmit an I-frame based on a predetermined period, in accordance with the checked frame type information and the sequence number, and transmits the I-frame to the reception apparatus using a variable time according to the determination.
