SPRM 15: Player Audio Configuration
Each DVD player can have several types of audio capabilities. Most players can handle
Dolby Digital (AC-3), Linear PCM, and MPEG Audio. There are other audio options such
as DTS and SDDS, as well as karaoke capabilities.
By reading the values of SPRM 15, you can see which audio options the player has. This
could be useful if you have two types of audio streams and want to play the proper one
for that player. For example, if the player is capable of Dolby Digital (AC-3) audio, you
might want to play that stream instead of a stereo PCM stream.
