Method and apparatus for transmitting data

摘要

A method of transmitting items of information from a plurality of data sources (25-28) to a data destination (9) over a common data channel. The method comprises: transmitting the items of information from each data source to the data destination as a series of data packets (70-73), each data packet being separated from successive data packets transmitted by the same data source by a repetition period, the repetition period of each data source being different from the repetition periods of the other data sources; and repeatedly transmitting each item of information from the same data source in at least N adjacent data packets, where N is the number of data sources, in order to ensure that at least one of the N successive data packets is received at the data destination without overlapping with data packets from the other data sources, wherein $where\; Period\; n\; is\; the\; repetition\; period\; of\; the\; nth\; data\; source\; and\; burst\; period\; is\; a\; parameter\; related\; to\; the\; length\; of\; the\; data\; packets.\mathop{\mathrm{image}}$
