|
|
|
<para>This document covers the Linux Kernel to Userspace API's used by
|
|
video and radio straming devices, including video cameras,
|
|
analog and digital TV receiver cards, AM/FM receiver cards,
|
|
streaming capture devices.</para>
|
|
<para>It is divided into three parts.</para>
|
|
<para>The first part covers radio, capture,
|
|
cameras and analog TV devices.</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 Remote Controller API</para>
|
|
<para>For additional information and for the latest development code,
