A system related to the retrieval of a media object list with associated properties from a media device such as a digital video camcorder, audio player or other source or device. The set of media objects properties (128) may be expanded to include a representative sample (132), as another attribute or property of the media object data (130). The representative sample data (138) may include data of a different type than that of the underlying media object data (130). When content is selected as the representative sample data (138), that data may be associated with a set of representative sample properties (136) which specify the type, attributes, properties or other metadata for the sample data. A media object may be accessed and sampled to allow a user to view or listen to representative content, through encapsulation of a sample in the properties passed via an underlying media transport protocol.
