摘要： The invention relates to a remote control protocol for a local action to generate a command message (OM), which permits a broadcaster to control a local action in at least one receiving station comprising: a step for transmission of an authorisation message (HM) from the broadcaster to the receiving station(s) and a verification step (4) in said receiving station(s), for transmitted authenticity parameters and addresses, with regard to parameters memorised in each of said receiving stations. The invention is characterised in that the authorisation message (HM) comprises a generation action (CM), at the level of the receiving station(s), a command message (OM), calculated locally and said protocol also comprises, conditional on the verification step (4), an interpretation step (10) of said action (CM) transmitted with said authorisation message (HM) and a local generation step (20) for a command message (OM) in response to said interpretation step (10). The above finds application particularly in transmission of encoded television information (I*).
