<title>Introduction</title>
<para>This document covers the Linux Kernel to Userspace API's used by
video and radio streaming devices, including video cameras,
analog and digital TV receiver cards, AM/FM receiver cards,
streaming capture and output devices, codec devices and remote
controllers.</para>
<para>It is divided into four parts.</para>
<para>The first part covers radio, video capture and output,
cameras, analog TV devices and codecs.</para>
<para>The second part covers the
API used for digital TV and Internet reception via one of the
several digital tv standards. While it is called as DVB API,
in fact it covers several different video standards including
DVB-T, DVB-S, DVB-C and ATSC. The API is currently being updated
to documment support also for DVB-S2, ISDB-T and ISDB-S.</para>
<para>The third part covers the Remote Controller API.</para>
<para>The fourth part covers the Media Controller API.</para>
<para>For additional information and for the latest development code,
see: <ulink url="http://linuxtv.org">http://linuxtv.org</ulink>.</para>
<para>For discussing improvements, reporting troubles, sending new drivers, etc, please mail to: <ulink url="http://vger.kernel.org/vger-lists.html#linux-media">Linux Media Mailing List (LMML).</ulink>.</para>
