Within the context of the broadcasting of DVB services over an IP network, the trend is to separate the signalling information describing the network and the services offered from the services themselves. The signalling is made available to the terminals via XML files available on HTTP servers. In contrast to this approach, the invention consists of a method of recognition, by a receiver connected to a bidirectional network, of digital services on the bidirectional network, which comprises a step in which the receiver connects to a first stream, a step in which the receiver extracts from said stream information on the location on the network, on the one hand, of streams conveying the content of these services and, on the other hand, of separate streams conveying information describing these services, a step in which the receiver connects to at least some of the streams conveying service description information to obtain information on these services and a step in which the receiver uses this information to construct a list, possibly unitary, of the services available on the network.
Method of recognition, by a receiver connected to a bidirectional network, of digital services on the bidirectional network, wherein it comprises at least the following steps:
Descriptor of a service for broadcasting a DVB stream for inclusion in an NIT, wherein it contains the broadcast IP address of a stream server and a port number to which said server broadcasts a DVB stream conveying the content of a service over an IP type network and at least one descriptor containing the broadcast IP address of a stream server and a port number to which said server broadcasts a DVB stream conveying signalling information relating to said service.
