Time to check out the ETSI docs. See ETSI EN 300 468 chapter 3 "Definitions an abbreviations": | multiplex: stream of all the digital data carrying one or more services | within a single physical channel | service: sequence of programmes under the control of a broadcaster which | can be broadcast as part of a schedule Also see Figure 1, which shows the hierarchy: Networks -> Multiplexes -> Services -> Components So "multiplex" and "service" are the DVB/ETSI defined terms.
