  • TV viewers are only very limited solutions that allow TV viewers to watch multiple TV channels (or multimedia streams, to put it in a more general form) at the same time.
  • some TV broadcasters offer a so-called conference view where multiple TV streams are shown at same time on a single TV channel.
  • this technique is applied in the field of sports related TV streams, especially in the case of the transmission of soccer games.
  • the transmission is switched between concurrently played soccer games at different locations.
  • the source changes when something interesting (goal, penalty, etc.) happens at the other place which is currently not shown and run in the background.
  • the decision regarding the content switch is made by the TV broadcaster with the TV viewer having no chance to influence this decision.
  • TV sets which are equipped with a so-called picture-in-picture functionality, which allows for two TV channels being displayed at the same time.
  • picture-in-picture functionality allows for two TV channels being displayed at the same time.
  • the technical features of the TV set limit the simultaneous display to two channels.
  • Metadata in general refer to some selected properties of other usually more complex data, that is, metadata form "data about data".
  • metadata may include information regarding the name, the director, the actors, the lengths, the language, etc. of a movie.

  • the aforementioned object is accomplished by a method comprising the features of claim 1.
  • a method comprising the features of claim 1.
  • such a method is characterized in the steps of specifying customized preferences on the part of the user regarding content and/or events he is interested in, selecting metadata which correspond to the user's specified preferences, and transmitting the selected metadata to the user's terminal.
  • a system for providing multimedia content to a user comprises a selection means for enabling the user to specify customized preferences regarding content and/or events he is interested in, and a metadata control function for selecting metadata which correspond to the user's specified preferences and for transmitting the selected to the user's terminal.
  • the user is enabled to specify customized content and/or events related preferences according to his interests.
  • Metadata which correspond to the user's specified preferences are selected by a metadata control function and then transmitted to the user's terminal.
  • the invention allows for real interaction as the user can specify preferences which are taken into account for the metadata provision process.
  • the delivery of the multimedia content is IP based, i.e. the digital data network which is used for the delivery of the multimedia content may be the Internet.
  • the invention can be based and built up on existing IPTV technology.
  • the metadata provided by said at least one metadata source is scheduled in advance according to configurable criteria.
  • the metadata provided by said at least one metadata source is related to real time or at least approximately real time events.
  • the metadata may be related to unpredictable events which happen on an random basis. For example, the user could be updated in real time about important events of a soccer game (goals, faults, penalties, etc.).
  • the metadata is transmitted together with the multimedia content in the same stream.
  • the metadata may be encapsulated inside the multimedia stream by means of any of the available protocols, i.e. MPEG or Ogg.
  • the metadata may be transmitted independent of the multimedia content, i.e. metadata and multimedia content are transmitted separately.
  • SIP messages may be employed for transporting the metadata, as SIP is the signalling protocol which is used for most of the streaming protocols.
  • WebServices may be used, as they are easy to implement and their robustness has been already proved.
  • the transmission mode of the metadata i.e. in-stream or out-stream, as described above
  • the metadata may automatically be transmitted in-stream, i.e. together with the multimedia content.
  • metadata provided by said at least one metadata source is continuously transmitted to the user's terminal and the metadata selection process according to specified user preferences is performed at the user side.
  • an entity which in the following is called metadata provider, may be established, which handles the metadata provided by said at least one metadata source.
  • the user may subscribe to the metadata provider and may provide his specified preferences to the metadata provider.
  • the metadata provider will perform a check of the metadata it receives on the basis of the specified preferences. Only metadata for which the check gives a positive result, i.e. the metadata corresponds with the user's specified preferences, are transmitted to the user.
  • the user's terminal may be configured to automatically react to the received metadata according to terminal specifications set by the user. Through this, it is possible that users will be notified, as the case may be, in real-time about contents and/or events in other channels without the need of manual interaction. Instead, the user may be automatically prompted with information pop-ups each time the user receives metadata, i.e. each time there is content and/or an event on one of the background channels which corresponds to his specified preferences.
  • the user's terminal may be configured to react in a completely automated way, for instance, but not limited to, switching temporally from one multimedia stream/channel to another, or, e.g.
  • the user may be enabled to create his personal profile to which a policy-based decision engine associated.
  • the behaviour of the user terminal may be set up by using the decision engine which may comprise personalized polices, priorities and/or preferences.
  • the system comprises a recording means for recording multimedia content.
  • the recording means may be configured to record multimedia content of a primary multimedia stream (i.e. the multimedia stream the user is primarily watching) during the shift to another multimedia stream received metadata is related to. After switching back to the primary multimedia stream, the missing part may be displayed from the recording means with the time shift.
  • the decision, whether the user wishes the missing part to be resumed or not, may be designed as a configurable parameter that may be predefined by the user.
  • the recording means may include, but is not limited to, a pre-cache implemented at the user's terminal or a personal video recorder which may be provided, e. g., in a set up box or in the network.
  • the metadata control function may comprise an event recognition means for identifying content and/or events that correspond to the preferences specified by the user. Most suitably, the recognition/identifying process is performed on the part of the content provider who, in general, disposes of all necessary information.
  • the content and/or event identification may be performed either manually or, alternatively or additionally, by computer based means, e.g. by employing image recognition software.
  • a recording means is suitably employed to be able to play back the content that has been identified as being relevant.
  • the system may comprise a metadata aggregation function for aggregating metadata from several metadata sources. The metadata aggregation function enables a user to arbitrarily combine different metadata.

  • Fig. 1 is a functional diagram in which the principal functions implemented in a method according to the invention are illustrated.
  • a so-called RTMDCF Real Time Metadata Control Function
  • the RTMDCF will be implemented at the content provider side who will provide the majority of the real time metadata, as the content providers have typically all necessary knowledge know when important events take place.
  • the metadata feeding may be employed at several different points.
  • service providers could be enabled to add personalized metadata depending on user profiles.
  • This metadata could be real time advertisements, special offers, etc.
  • users themselves may be enabled to generate their own metadata, e.g. to inform friends about interesting IPTV content and/or events, even though those friends are not subscribed to the respective multimedia channel.
  • users may be enabled to set up in their preferences the way of how to react in front of a U2U (user to user) metadata depending on the relation level with the other user.
  • the RTMDCF handles over the metadata to a so-called MDACF (Metadata Aggregator Control Function).
  • MDACF Metal Aggregator Control Function
  • This function is responsible for aggregating metadata from one or several RTMDCFs. Furthermore, it might add scheduled metadata from third parties. In a general scenario, also the handling of user subscriptions will be performed by the MDACF.
  • the MDACF will be most suitably implemented at a new type of service provider which could be named "metadata provider".
  • the function of the metadata provider will be described in more detail in conjunction with Fig. 2. However, any other provider will be able to send metadata directly to end-users.
  • a so-called UECF User Equipment Control Function
  • the UECF consumes metadata and may control the user's policy decision engine. This engine handles the interpretation of messages contained in the metadata and controls an automatic reaction according to the profile predefined by the user. In this context the user can set up his IPTV equipment to behave in a certain way through several options like configuration files, user policies, or metadata priority. Finally, the UECF is enabled to provide U2U metadata.
  • the functions as described above may be freely distributed amongst the various entities.
  • the UECF can be co-located with the MDACF on the same device, e.g. the user's terminal. This is illustrated in Fig. 1 by means of the arrows which indicate the metadata flow via the MDACF (solid line arrows) or, alternatively, directly to the UECF (dashed line arrow).
  • Fig. 2 is a schematic illustration of a preferred embodiment of a system according to the invention.
  • Fig. 2 depicts three content providers CP1 , CP2 and CP3.
  • Each content provider provides a multimedia channel, which are TV channels in the embodiment shown.
  • content providers CP1 and CP2 transmit a soccer game, respectively.
  • the TV content of content provider CP3 is not further specified. It is to be noted that all of the three TV channels mentioned above could be provided by a single content provider.
  • a user has subscribed to channel 1 of content provider CP1 and to channel 2 of content provider CP2.
  • the user receives preconfigured or customized metadata.
  • the metadata which are provided by the content providers CP1 , CP2 and CP3 are transmitted to a metadata provider MP (see the dashed line arrows).
  • the user specifies his preferences regarding content and/or events he is interested in and transmits this information to the metadata provider MP.
  • the metadata provider MP continuously receives metadata from the content providers CP1 , CP2 and CP3 and checks them by performing a comparison with the currently deposited user preferences. If a matching is detected, i.e. if metadata correspond to the user's specified preferences, the metadata is selected and transmitted to the user's terminal.
  • the metadata transmitted to the user's terminal (which might be a computer based, enhanced Set Top Box (STB), a PDA, a mobile device, etc.) will allow the user to be updated in real-time about content events in other channels without the need of manual interaction.
  • STB enhanced Set Top Box
  • PDA personal digital assistant
  • a mobile device etc.
  • the behavior of the client's software may be set up by using personal policies that the user will have associated to his profile, wherein the policies can be related to channel selection and IPTV client behavior. Every user profile will be also associated to a device. In that way, users will be able to specify some specific options when playing the content with a STB and some others while watching it with a small PDA.
  • the metadata is typically related to not-foreseeable/unpredictable events which randomly happen.
  • the user has chosen the soccer game transmitted via channel 1 as primary TV stream he wants to watch. Furthermore, he has specified his preferences in that he is interested in important events (goal, faults, penalties, etc.) which happen in the other soccer game transmitted via channel 2.
  • the metadata provider MP is continuously fed with metadata from the content providers CP1 , CP2 and CP3. If the metadata provider MP receives metadata related to e.g. a goal in soccer game 2, the metadata provider MP transmits a respective metadata to the user's terminal. At the user's terminal a main event alert appears, and the notification is pop-upped on the user's terminal.
  • the user's terminal reacts automatically depending on his set specifications. This is, an automatic channel switch is performed, or both TV streams (channel 1 and channel 2) are displayed simultaneously at the user's terminal. After the important event has been displayed, the user comes back to the primary match in live. However, he can be given the option to resume the missing part or not. Alternatively, the user is enabled to reject the important event in the soccer game transmitted via channel 2 by simply closing the pop-up window.
