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.
|
||
|
|
|
||
|
|
A typical media device hardware is shown at

The media infrastructure API was designed to control such devices. It is
|
||
|
|
divided into four parts.
|
||
|
|
|
||
|
|
The first part covers radio, video capture and output, cameras, analog
|
||
|
|
TV devices and codecs.
|
||
|
|
|
||
|
|
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/T2, DVB-S/S2, DVB-C, ATSC, ISDB-T, ISDB-S,etc. The
|
||
|
|
complete list of supported standards can be found at
|
||
|
|
:ref:`fe-delivery-system-t`.
|
||
|
|
|
||
|
|
The third part covers the Remote Controller API.
|
||
|
|
|
||
|
|
The fourth part 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.
