Abstract: A digital signal to be received by a plurality of receivers, particularly restricted-range receivers, and divided into signal frames of which at least some include both a main data channel consisting of sub-channels, and a data transport path including at least one data channel consisting of separate data blocks dedicated to a single service and known as containers. Each container includes a header (41) consisting of a selection sub-header (44) containing, inter alia, data (46) for identifying a group of at least one container destination receiver, and a service sub-header (45) containing, inter alia, dedicated service data; a separately convolutionally coded working data field (42) containing source data for a given service; and an error detection and/or correction data field 943).
