Typical Media Device
|
|
|
|
|
|
|
|
|
|
The media infrastructure API was designed to control such devices. It is
|
|
|
|
|
divided into four parts.
|
|
|
|
|
|
2016-07-01 08:52:52 +08:00
|
|
|
The :Ref:`first part <v4l2spec>` covers radio, video capture and output,
|
2016-07-01 04:12:20 +08:00
|
|
|
cameras, analog TV devices and codecs.
|
2016-06-30 21:18:56 +08:00
|
|
|
|
2016-07-01 08:52:52 +08:00
|
|
|
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
|
2016-06-30 21:18:56 +08:00
|
|
|
:ref:`fe-delivery-system-t`.
|
|
|
|
|
|
2016-07-01 08:52:52 +08:00
|
|
|
The :Ref:`third part <remote_controllers>` covers the Remote Controller API.
|
2016-06-30 21:18:56 +08:00
|
|
|
|
2016-07-01 08:52:52 +08:00
|
|
|
The :Ref:`fourth part <media_controller>` covers the Media Controller API.
|
2016-06-30 21:18:56 +08:00
|
|
|
|
|
|
|
|
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.
