Abstract
The method is for generating a digital multiplex signal for broadcasting. The multiplex is made up of packets of determined length coming from a plurality of sources, by applying a treatment selected from those belonging to a catalog of stored treatments. It is applicable to D2-MAC/packet and digital TV. An encoder implementing the method has sources in which the identity of the treatment to be performed is inserted in a field provided for this purpose in each packet precursor. Downstream from the sources, the encoder comprises a treatment unit for decoding the field and for causing the treatment defined by the field to be applied.
