FIELD: image transferring equipment engineering, possible use in multimedia communications.
SUBSTANCE: in accordance to method, when error codes are detected on receiving side, data of code stream of image with error codes are refused prior to decoding of data of code stream of image, and refused data of code stream of image are replaced with data of code stream of image, positioned in appropriate position of previous frame, and data of code stream of image are encoded continuously. Also, an array of marks is set up for data of code stream of image prior to encoding on receiving side, to perform recording of positions, where error codes have been detected.
EFFECT: possible avoidance of transfer of internal frame images on transmitting side and of frozen images on receiving side, or decrease of their occurrence periods, thus improving quality of image.
