+ 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, DVB-S, DVB-C and ATSC. The API is currently being updated - to documment support also for DVB-S2, ISDB-T and ISDB-S. + DVB-T/T2, DVB-S/S2, DVB-C, ATSC, ISDB-T, ISDB-S,etc. The complete + list of supported standards can be found at + . 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.
