A method and a device for transferring service data stream such as compressed video signal including both non-predictive and predictive data frames of a common data type. Larger non-predictive frames are transmitted on demand only ( 1014 ) upon occurrence of a triggering event ( 1004, 1006 ). Otherwise, solely predictive frames of smaller size are transferred ( 1008 ) to cut down the transmission delay.
