摘要:
A method of transmitting data to a receiver/decoder comprises: transmitting first type visual and/or audio data to the receiver/decoder; and transmitting second type reference data associated with the first type visual and/or audio data to the receiver/decoder to enable the receiver/decoder to generate further visual and/or audio data in dependence on the reference data; wherein the first type data and the second type data have a predetermined timing relationship.
