The conversion script added some comments at the end. They point to the original DocBook files, with will be removed after the manual fixes. So, they'll be pointing to nowere. So, remove those comments. They'll be forever stored at the Kernel tree. So, if someone wants the references, it is just a matter of looking at the backlog.

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, Software Defined Radio (SDR),
|
|
streaming capture and output devices, codec devices and remote controllers.

Typical Media Device
|
|
|
|
The media infrastructure API was designed to control such devices. It is
|
|
divided into four parts.
|
|
|
|
The :Ref:`first part <v4l2spec>` covers radio, video capture and output,
|
|
cameras, analog TV devices and codecs.
|
|
|
|
The :Ref:`second part <dvbapi>` 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/T2, DVB-S/S2, DVB-C, ATSC, ISDB-T, ISDB-S,
|
|
DTMB, etc. The complete list of supported standards can be found at
|
|
:ref:`fe-delivery-system-t`.
|
|
|
|
The :Ref:`third part <remote_controllers>` covers the Remote Controller API.
|
|
|
|
The :Ref:`fourth part <media_controller>` covers the Media Controller API.
|
|
|
|
It should also be noted that a media device may also have audio
|
|
components, like mixers, PCM capture, PCM playback, etc, which are
|
|
controlled via ALSA API.
