Dear all, in my opinion there is a need to get rid of the transport stream encapsulated PSI/SI sections/tables in the second generation DVB systems for signaling purposes, especially in those cases where only Generic Stream Encapsulation is being used. Essentially there are two kinds of signaling, one for physical link and network properties, and the other one for services. The latter one is well addressed by all those parties interested in AV/TV/... over IP, whereas the first one is still delt with so-called backward compatibility mode (so TS encapsulated signaling sections). Although ULE/GSE provide an extension header for carrying TS packets, this is a suboptimal choice given that any kind of signaling shall support unidirectional mode of operation and boot strapping of rx-only devices. This is not to propose a solution rather than to point out that there is standardisation work needed in this area. Whether it fits in the ipdvb agenda is to be discussed.
