- a UPnP ATTB command named "Browse”
- Creating a label involves saving all or part of the metadata of a content in a dedicated storage area, in this case in the SZ storage area, so that this metadata is treated as data from a label , that is, an object for marking content and intended to be presented in a user interface in relation to that content.
- a tag is also a means for storing information about a content.
- all the metadata giving information on the labeled content interpretable by a user (title, author, etc.) or usable as a search criterion for searching and retrieving this content are retained to constitute the label as well as any identifier or address to access a server through which this content is accessible.
- the DMC control device is thus designed to store, in the tag, in the metadata constituting the tag or in association with this metadata, a content identifier assigned by the UPnP DMS content server and an identifier (in the form of a tag). eg hypertext link or address) of a server from which access to this content is possible.
- a server is for example a content download server, a content broadcast server, a content search server, a content purchase server, etc.
- a label is also a means of accessing the labeled content.
- the server thus identified may be distinct from the CS server providing the content in question. But it can also be the CS server. In the case where the CS server is a streaming content server, the identified server will generally be distinct and able to provide content to download regardless of any broadcast performed by the CS server.
- the identifier of the remote server stored in the tag is either provided by the UPnP DMS content server in the metadata of the content under consideration, or generated by the DMC control device: thus, when no content server identifier is available for the content in question (this is the case of ephemeral content having been broadcast during a time interval elapsed by a server of broadcasting content), the DMC control device is designed to store in the metadata defining the label created for this content, an identifier of a server providing a content search service.
- the storage area SZ is also used to store a WP file, for example as an HTML page or XML file, used to generate a user interface page to present the labels to the user via an interface user of a terminal.
- a WP file for example as an HTML page or XML file

- This user interface page is designed so that when a user clicks on a UI element representing or associated with a tag, an HTTP request is sent to the server whose identifier is stored with the user. label and through which access to this content is possible.
- This request optionally includes a subset of the content metadata constituting the label.
- the request is formed for example from a Uniform Resource Identifier (URI) address comprising a server identifier and optionally a subset of the metadata (title, artist, etc.) of the tagged content used to trigger a search or identification of the content. using this subset of metadata as the search criteria:
- URI Uniform Resource Identifier
- the WP file defines an RSS feed that is established when this interface element is clicked: the user of the MT terminal, provided that this terminal is equipped with an RSS reader, is then linked to the server whose identifier is stored and / or displays information on the content and / or access to an interface for accessing the content with which the label is associated.
- the user interface page generated by the DMC control device is in this case designed so that when a user clicks on an interface element user, representative or associated with a tag, a link, with a search interface of a search engine of the identified content search server, is established to automatically trigger a search for content.
- This makes it possible to search for content having the same metadata as those constituting the tag or having at least some metadata common with this tag (same author for example).

- the control device DMC then updates in the storage area SZ the metadata associated with this content with the metadata newly provided by the server CS.
- the metadata of content being broadcast is potentially richer or more detailed than the metadata that may be collected from the same server during a metadata collection phase prior to this broadcast.
- the remote content server CS is a server broadcasting a continuous FX stream - corresponding for example to a streaming service of contents for a radio station or a television channel -
- the metadata provided by the associated metadata server to this service during the broadcast of a content are metadata specific to this content (for example the song currently broadcast on the radio or the program currently broadcast on the television channel).
- the metadata provided prior to this broadcast is just continuous stream metadata, that is broadcast service metadata, giving information about that service (radio name, radio frequency, or name of the broadcast service). channel, etc.) and, optionally, a mailing list (called a program guide, or EPG in the case of a television channel) relative to a given period of time (for a day for example).
- the DMC control device is designed to determine whether the content for which labeling has been requested is content identified as being a streaming stream, and, if so, to query the DMS content server for they get metadata specific to the content commonly distributed via this stream An enrichment of the metadata is thus possible when the user requires a labeling during a restitution, since the metadata thus obtained are specific to the content commonly broadcast and not specific to the stream broadcast, considered as a whole, without taking into account. different content broadcast via this stream
- the steps H10 and H20 of the metadata collection phase are executed by the control device DMC and not by the content server UPnP DMS.
- the control device DMC also stores the collected tags. in a metadata directory, in association with files to generate user interface pages
- the steps G20, H30, H40 and G30 for obtaining metadata are then no longer necessary for the labeling of a content the control device DMC is able to obtain the metadata associated with one of the contents referenced by the local content server DMS from a remote server of the IPN network.
- This remote server is either a metadata server associated with the remote content server CS broadcasting, storing or storing at the disposal of the content considered, either directly the remote content server CS broadcasting, storing or making available the content considered
- control device DMC is able to obtain from the content server DMS, not directly the metadata of a content to be labeled, but an identifier (in the form of an address or a URL, Uniform Resource Locator a remote metadata server
- an identifier in the form of an address or a URL, Uniform Resource Locator a remote metadata server
- This identifier is for example present in the metadata of a service provided by the remote server CS considered, these metadata being obtained via the local content server DMS by interrogation, via the platform d intermediation or not, different CS remote content servers
- service metadata are stored in the database BDD
- the DMC control device When this identifier is likely to vary over time, it suffices for the DMC control device to interrogate the DMS content server at periodic time intervals (for example once a day, or once an hour) to obtain the identifier current
- the local DMS content server interrogates, via the intermediation platform or not, the various remote content servers CS
- the DMC control device is designed to determine whether the content for which labeling has been requested is identified as a streaming stream, and if so, to obtain, without going through the UPnP DMS Content Server, metadata available for content that is commonly delivered through this feed.
- the invention allows the labeling of contents, whether these contents are being restored or not, provided via a continuous stream or not.
