METHOD AND DEVICE FOR CONTINUOUS ADAPTATION OF CODING PARAMETERS TO A VARIABLE USER-DATA RATE

摘要

A method and a device for continuous adaptation of coding parameters to a variable user-data rate of a datastream composed of data frames. Data packets and ensembles are received and associated with services for mobile receivers. The transmission requirement of the next ensemble is determined based on the buffered data packets. Optimised coding parameters for the ensemble in the next data frame are then determined based on certain factors, such as the transmission requirement for the uncoded ensemble and the determined transmission capacity.
