Overview: DLNA playback
DLNA playback uses discovery, media descriptions and device-specific compatibility information to connect a source with a receiver.
A DLNA receiver needs both a reachable resource and a representation it can interpret. Device profiles describe the relevant compatibility relationship rather than changing the receiver's hardware. These pages connect that information to media selection and delivery through a DLNA path.

DLNA media playback uses interoperable media and UPnP AV roles to discover content, select a renderer and establish a supported media-delivery path.DLNA device profiles
A DLNA device profile describes identification and media-handling rules used to offer a representation compatible with a particular receiving path.
