<para>This section describes the DVB version 5 extension of the DVB-API, also
called "S2API", as this API were added to provide support for DVB-S2. It was
designed to be able to replace the old frontend API. Yet, the DISEQC and
the capability ioctls weren't implemented yet via the new way.</para>
<para>The typical usage for the <constant>FE_GET_PROPERTY/FE_SET_PROPERTY</constant>

		<para>This ISDB-T/ISDB-Tsb API extension should reflect all information

		<para>The information given here should help application writers to know how
			to handle ISDB-T and ISDB-Tsb hardware using the Linux DVB-API.</para>
		<para>The details given here about ISDB-T and ISDB-Tsb are just enough to
			basically show the dependencies between the needed parameter values,
			but surely some information is left out. For more detailed information
			see the following documents:</para>
		<para>ARIB STD-B31 - "Transmission System for Digital Terrestrial
			Television Broadcasting" and</para>
		<para>ARIB TR-B14 - "Operational Guidelines for Digital Terrestrial
			Television Broadcasting".</para>
		<para>In order to understand the ISDB specific parameters,
			one has to have some knowledge the channel structure in
			ISDB-T and ISDB-Tsb. I.e. it has to be known to
			the reader that an ISDB-T channel consists of 13 segments,
			that it can have up to 3 layer sharing those segments,
			and things like that.</para>
