711                 <para>This ISDB-T/ISDB-Tsb API extension should reflect all information
712                         needed to tune any ISDB-T/ISDB-Tsb hardware. Of course it is possible
713                         that some very sophisticated devices won't need certain parameters to
714                         tune.</para>
715                 <para>The information given here should help application writers to know how
716                         to handle ISDB-T and ISDB-Tsb hardware using the Linux DVB-API.</para>
717                 <para>The details given here about ISDB-T and ISDB-Tsb are just enough to
718                         basically show the dependencies between the needed parameter values,

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