823 provides more than a single delivery system, FE_GET_INFO doesn't help much.

902 <para>In order to understand the ISDB specific parameters,
903 one has to have some knowledge the channel structure in
904 ISDB-T and ISDB-Tsb. I.e. it has to be known to
905 the reader that an ISDB-T channel consists of 13 segments,
906 that it can have up to 3 layer sharing those segments,
