Method for transmitting services information in different types of broadcasting networks and unit for processing said information

A method for transmitting services information in a broadcasting network by at least one managing center towards a plurality of processing units connected to a first network of DVB type and to a second network of IP type, both networks broadcasting digital data streams including content data of services and additional information data on said services structured in tables adapted to the transmission protocol specific to each type of network, the method comprises the steps of:

• exploring the first and second network and extracting services information from the streams broadcasted by the first network and the second network,
• inserting services information extracted from the streams of the second network into an information table transmitted by the first network, said information table being situated at the highest level in the hierarchy of the services information tables of the first network, said services information including at least one descriptor comprising an identifier of a service broadcasted by the second network and an IP address corresponding to said service, obtaining a modified information table,
• transmitting the modified information table in the streams broadcasted by the first network towards the processing units, said modified information table contributing to reduce the analysis and processing tasks executed by the processing units during determination of the service of the second network corresponding to a currently received service of the first network.
