Abstract
A wireless communication system comprises a broadcast transmitter broadcasting textual and multimedia information to a remote receiver unit. The broadcast transmitter is operably coupled to a signal manipulation function and arranged to receive and process a broadcast signal that comprises both a textual portion and multimedia information. The signal manipulation function separates the textual and multimedia information into multiple bursts of data sub-blocks, wherein substantially each sub block comprises the textual data and a sub-block of multimedia information for transmitting to the remote receiver unit.By implementing the aforementioned inventive concepts, faster access to the most important (i.e. semantic) part of the transmitted information can be obtained.
