Abstract:
A method for transmitting video images between multimedia terminals in a data transmission system, in which video images are transmitted by using first video frames (I), in which information encoded from one video image is transmitted, as well as second video frames (P, B), in which information encoded on the basis of two or more video images is transmitted, from which a video image can be formed in the receiver multimedia terminal by using at least one first (I) and at least one second video frame (P, B), wherein, in the method there is provided a fast forward or fast rewind function, and that the fast forward or fast rewind function of the video images is performed primarily by transmitting only first video frames (I) and, wherein {PRIVATE }the quantity of information is reduced by storing counterparts of said first (I) and second video frames (B, P), said counterparts of said first (I) and second video frames (I, B, P) being formed by reducing the quantity of information of said first (I) and second video frames (B, P), wherein during the fast forward or fast rewind function the counterparts of said first (I) and second video frames (B, P) are transmitted.
