Patent ID: 7843959

Claim:
A transmission device for prioritising data elements of a data stream for transmission to a receiving device, comprising: decodability determining means for determining a decodability of a current data element, the decodability indicating the extent to which the current data element is decodable at the receiving device; prioritising means for assigning a priority to the current data element based on the determined decodability; and a transmitter controller for scheduling a transmission of the current data element to the receiving device based on the priority, wherein, the data stream comprises: independent data elements being independent from other data elements and dependent data elements being dependent on at least one reference data element, wherein the decodability determining means is configured to set the decodability of an independent data element to a maximum decodability and to set the decodability of a dependent data element equal to the decodability of the reference data element, when the reference data element has been transmitted.
