Media objects are transformed into active, connected objects via
identifiers embedded into them or their containers. In the context of a
user's playback experience, a decoding process extracts the identifier
from a media object and possibly additional context information and
forwards it to a server. The server, in turn, maps the identifier to an
action, such as returning metadata, re-directing the request to one or
more other servers, requesting information from another server to
identify the media object, etc. The linking process applies to broadcast
objects as well as objects transmitted over networks in streaming and
compressed file formats.
