Information technology - UPnP Device Architecture - Part 14-12: Audio Video Device Control Protocol - Level 3 - Audio Video Content Directory Service

ISO/IEC 29341-14-12:2011(E) describes a service template which is compliant with the UPnP Device Architecture version 1.0. It defines a service type referred to herein as ContentDirectory service. The purpose of the ContentDirectory service is to allow the server device provide a uniform mechanism for UI devices to browse the content on the server and to obtain detailed information about object individual content. The ContentDirectory service additionally provides a lookup/storage service that allows clients to locate (and possibly store) individual objects (for example, songs, movies, pictures, etc) that the (server) device is capable of providing.
