The present invention relates to a method for a media aggregating node, for a media-ad muxer node of a local network and for an external network-connected UE, of publishing user-adapted advertisements in a user-selected media content on a user-selected local network-UE, as well as to the media aggregating node, the media-ad muxer node of the local network, and to the external network-connectable UE.
A local network, e.g. a home network or an office network, may comprise several connected consumer electronic devices, e.g.
personal computers, mobile phones, set-top-boxes and gaming consoles. Electronic devices within a local network can be adapted to communicate with each other e.g. according to DLNA (Digital Living Network Alliance) standard, which allows consumer electronic devices to communicate and share media content with each other, thereby enabling e.g. access of media files residing e.g. on a PC directly on a TV within the e.g. a DLNA home network, without a complicated configuration process.
A DLNA-compatible device is able to communicate with other DLNA-compatible devices within the DLNA network via the Universal Plug and Play (UPnP), which is a network protocol that is capable of establishing communication between DLNA-compatible devices within a DLNA network, without any configuration. By means of the UPnP, a DLNA device is able to e.g. discover and address other available DLNA devices within a DLNA network, and receive a description of their capabilities.
The DLNA-compatible devices within a DLNA network are typically of different types, based on their function in the media distribution and rendering, and the types involve a DMS (Digital Media Storage/Server), a DMP (Digital Media Player), a DMR (Digital Media Renderer), and a DMC (Digital Media Controller). A DMS may be e.g. a PC (Personal Computer) or a NAS (Network Attached Storage), and it is a device that stores media content and makes it available to a wired and/or wireless networked DMP or DMR. A DMP may be e.g. a TV, a stereo, a game console, or a mobile phone, and is a device that is able to find content on a DMS, and provide playback and rendering capabilities. Further, a DMC is a device that locates content on a DMS and plays it on a DMR, and a DMC may be e.g. a PDA (Personal Digital Assistant) or a mobile phone. Finally, a DMR is a device that plays content received from a DMC and it may be a TV, an audio/video receiver, a video display or remote speakers.
It is advantageous to be able to insert advertisements to a media session stream, but this is not possible according to e.g. the conventional DLNA-standard. Further, in a conventional DLNA network, the end-user of a DLNA device can not be identified, since there is no authentication mechanisms involved in the DLNA standard. Thus, advertisements can not be adapted to a particular user, e.g. to his/her age, interests or gender.
Thus, it still presents a problem to enable an insertion of personalized and targeted advertisements in a media session stream of a local network device, e.g. in a DLNA-compatible device of a DLNA network.
The object of the present invention is to address the problem outlined above, and this object and others are achieved by the method and the arrangement according to the appended independent claims, and by the embodiments according to the dependent claims.

The present invention will now be described in more detail, and with reference to the accompanying drawings, in which:
In the following description, the invention will be described in more detail with reference to certain embodiments and to accompanying drawings. For purposes of explanation and not limitation, specific details are set forth, such as particular scenarios, techniques, etc., in order to provide a thorough understanding of the present invention. However, it is apparent to one skilled in the art that the present invention may be practised in other embodiments that depart from these specific details.
Moreover, those skilled in the art will appreciate that the functions and means explained herein below may be implemented using software functioning in conjunction with a programmed microprocessor or general purpose computer, and/or using an application specific integrated circuit (ASIC). It will also be appreciated that while the current invention is primarily described in the form of methods and devices, the invention may also be embodied in a computer program product as well as in a system comprising a computer processor and a memory coupled to the processor, wherein the memory is encoded with one or more programs that may perform the functions disclosed herein.
In the following, the term local network-UE (User Equipment) is defined as a device that is capable of operating in a local network and communicating with the other devices in the local network, e.g. in a DLNA network. The term external network is defined as another network than the local network, and the term external network-connectable UE or external network-connected UE is defined as a device that is capable of communicating with this external network. According to a preferred embodiment of the invention, the external network corresponds to the Internet, but this invention is not limited thereto.
Conventionally, a DLNA network comprises one or more DMS (Digital Media Storage/Server) for storing media content, and the available media content can be presented to a user on a DMC (Digital Media Controller), typically in the form of tree structure. Thereafter, a user-selected media content, such as video- or audio-media or an image, can be made available by the user to be played or rendered on a DMP (Digital Media Player) or on a DMR (Digital Media Renderer).
However, according to this invention, an external-network-connectable UE (User Equipment), such as e.g. an Internet-enabled mobile phone or a PC, is used for controlling and navigating media content within the local network (e.g. a DLNA network) via a media aggregating node, for pushing the media content directly to a first local network-compatible UE, e.g. to a DLNA-compatible PC, TV or radio, via a virtual control node of the local network. The end-user logs in to an external network-connectable UE and starts playing a selected media session on a device of a local network, to which the user, or an associated user, is logged-in via a virtual control node of the local network, by attaching the UE to a media aggregating node, and sending a play command selecting said device and the media session to play. The media aggregating node authenticates the end-user and checks that he/she is also logged in to the local network, and forwards the play-command to the device in the local network via the virtual control node.
Said media aggregating node is responsible e.g. for authenticating a user logged in to the UE and a user logged in to the virtual control node of the local network, and the virtual control node controls and communicates with the local network-compatible devices of the local network. The external network-connectable UE communicates with the media aggregating node, which, in turn, communicates with the virtual control nodes of the local networks. Thereby, the external network-connectable UE is able to function as a custom-optimized navigation client, without the restrictions imposed e.g. by the DLNA and the UPnP. Further, the media files can be streamed on-demand to the local network-UEs, and do not have to be downloaded locally prior to playing.
Audio- and video advertisements, as well as media content, could be hosted anywhere on Internet. According to this invention, the media aggregating node 2 controls the insertion of advertisements into a media session stream playing on a DLNA device by communicating with an advertisement logic server node. Further, in order to control a dynamical shift between a media session stream, provided by a media streaming server, and an advertisement stream, provided by an advertisement streaming server, a media-ad muxer node is inserted into the local network for handling the insertion. The media-ad muxer node communicates with the media aggregating node, in order to receive information, e.g. URLs, regarding which advertisements to insert, and when to insert them.
Since the playing of the media content is initiated by an external network-connected UE, e.g. a personal mobile phone or a personal computer into which a user logs in, the identity of the user is known to the media aggregating node, thereby enabling the media aggregating node to find targeted and personalized advertisements to insert into the media content. Thus, it is possible to adapt the inserted advertisements to a specific person, and to his or her profile and previous advertising interaction, even though the DLNA device that is used for play-out is not authenticated.
Further, when an advertisement stream is muxed into a media session stream, a notification may be pushed to the external network-connected UE from the media aggregating node, the notification referring to additional advertising information and data, such as e.g. purchase opportunities. Alternatively, the external-network-connected UE may ask the media aggregating node with regular interval if any additional advertisement information exists. If additional advertisement data exists, or in response to a notification, the user of the external network-connected UE is able to obtain advertisement information to be displayed directly on the external network-connected UE, thereby providing feedback regarding the interest in the advertisement and the advertising selection process. Alternatively, when the media aggregating node receives a notification from the media-ad muxer that additional advertisement information is available, the media aggregating node may fetch information from the advertisement logic server and forward directly to the external network-connected UE.
The selection of advertisement to insert in a media session stream is based on e.g. the user profile, the previous interaction of the user with advertisements, the contextual metadata of the user-selected media content that is playing, as well as business rules combining these into a suitable selection of advertisements.
In an exemplary use-case according to an embodiment of the present invention, according to which the local network is a DLNA network and the external network is the Internet, a user logs in to an Internet-connected UE, e.g. to a mobile phone or a PC. Thereafter, the user requests the media aggregating node to send information regarding e.g. available and popular radio news programs from a pre-selected Internet-media content provider, as well as regarding available and suitable DLNA-compatible devices. In response, the user receives a list comprising short descriptions, thumbnails and various additional metadata, provided by the Internet-media content provider via the content data-node and the media aggregating node, as well as a list of available and suitable devices within the available DLNA networks in return. The user selects e.g. a DLNA-compatible radio located in the living room, and sends a play command to the media aggregating node indicating the selected news program and the selected radio in the living room.
The media aggregating node forwards the play command via the virtual control node, the command also indicating that a stream shall be provided to the selected radio by a media-ad muxer node. The media-ad muxer node will receive a playlist from the media aggregating node containing URLs for the user-selected media content, as well as for user-adapted advertisements obtained from an advertisement logic server, and create a stream by fetching the media and the ads from streaming servers, to be forwarded to the radio in the living room. The media aggregating node may push the playlist to the media-ad muxer, or alternatively, send the playlist in response to a request.
As a result, two 30-seconds radio advertisement spots are played prior to the actual media content, and the radio spots are selected based on the fact that the user has selected a sport news program, on the user profile, e.g. age, gender, interest, as well of previous ratings on radio commercials. During the airing of the radio advertising spots regarding male sport shoes, the mobile phone or PC of the user indicates e.g. by a tone, that additional advertising information is available. In response, the user indicates that he wants to learn more, using suitable input means on the mobile phone or PC, which will result in that the mobile phone or PC displays a webpage offering affordable sport shoes.
Thus, the present invention is implemented by means of a media aggregating node (MA), a media-ad muxer node (MUX), and of an external network-connectable UE, e.g. an Internet-connectable UE (IC UE), as described below:
Other nodes that are involved in the implementation of the present invention are the following:
The above-described nodes are all illustrated in
In signal S3, the DLNA UE sends a UPnP Publish to the VC 4 comprising presence information, e.g. that it is available. The VC, in turn, forwards the presence information to the MA, in signal S4. In signal S5, the MA sends information regarding Internet media content to the IC UE, after receiving a request from the IC UE, and the Internet media content-information has been obtained by the MA from a content-provider via a content data-node (not illustrated in the diagram). Further, in signal S6, the MA sends information regarding available and suitable DLNA UEs to the IC UE. Thereafter, using the information received in signals S5 and S6, the user is able to select an Internet media content and a DLNA UE, and send a play command to the MA, to be forwarded to the DLNA UE via the VC.
Thus, the media aggregating node 2 receives status and presence information from the local network-UEs of the local network via the virtual control node 4. When a user logs in to an external network-connected UE 1 outside the local network, the media aggregating node receives user login information from the external network-connected UE. The media aggregating node authenticates the user, and sends information regarding external network-media to the external network-connected UE, in response to a request. Further, it determines whether or not the user, or an associated user, is also logged in to a virtual control node, with which the media aggregating node is communicating. If so, the media aggregating node will send information regarding available and suitable local network-UEs to the external network-connected UE, typically in response to a request. When the media aggregating node receives a user-selected control command associated with a selected external network-media and a selected local network-UE from the external network-connected UE, it will forward the control command to the virtual control node.
Next, the media-ad muxer fetches a media stream from the streaming server 8, in signal S8, and the advertisement stream from the advertisement streaming server, in signal S9, and creates a media-ad stream for the DLNA UE, in signal S10. The DLNA UE issues a UPnP publish, in signal S11, that the media content is being played. Further, the media-ad muxer issues a notification to the MA, in signal S12, which is pushed to the IC UE, in signal S13, the notification referring to additional advertising information that is available. In response to the notification, the IC UE requests the MA, in signal S14, to fetch and return the additional info. Accordingly, the MA obtains the advertisement info from the advertisement logic server, in signal S15, and forwards directly to the IC UE, in signal S16.
According to a further exemplary embodiment, the media-ad muxer node pushes a notice to the external network-connected UE via the media aggregating node that additional advertisement info is available, after having provided the media-ad stream to the local network-UE, and the notice is received by the external network-connected UE in step 43. As a response, the external network-connected UE obtains the advertisement info, in step 44, by requesting the MA to fetch the information.
According to alternative exemplary embodiments of the invention, the media aggregating node pushes the playlist to the media-ad muxer node, or sends the playlist to the media-ad muxer node in response to a request.
According to a further embodiment of the invention, the media aggregating node receives a notice from the media-ad muxer that additional advertisement information is available, and forwards to the external network-connected UE. In response, the media aggregating node may receive a request from the external network connected UE to fetch additional advertisement information, e.g. from an advertisement logic server, and forward to the external network-connected UE. Alternatively, the media aggregating node fetches the advertisement info from the advertisement logic server and forwards to the external network-connected UE, directly after receiving the notice from the media-ad muxer node.
According to a still further embodiment, the media aggregating node receives and stores advertisement user-ratings originating in the external-network connected UE.
According to a further exemplary embodiment of the invention, the media-ad muxer sends a notice to the media aggregating node that additional advertisement information is available.
The device 71 for communicating with the media aggregating node further comprises a sender and a receiver, the sender arranged to forward login information from a logged-in user, the user logged in to a virtual control node of a local network, and to send a play command to the media aggregating node to play a user-selected media content on a user-selected local network-UE.
According to a further embodiment, the sender and the receiver of the device 71 for communicating with the media aggregating node is arranged to receive information that additional advertisement information is available, and to obtain the information by requesting the media aggregating node to fetch it from an advertisement logic server.
As described previously, the media aggregating node 2 is responsible for authenticating the user, for processing all requests and presence messages, for storing data and making the user profile available, and for handling media and device metadata to be displayed on an external-network connected UE. The media aggregating node comprises a device 81 for communicating with the external network-connected UE 1, said device comprising a receiver arranged to receive e.g. user login information from the user of an external network-connected UE, as well as a command to play a user-selected media content on a user selected first local network-UE.
The media aggregating node is further provided with a device 82 for communicating with one (or more) virtual control nodes 4, said device comprising a sender arranged to send a command to play the a media content an a local network UE as a media-ad stream comprising user adapted advertisements, the stream to be provided by the media-ad muxer node.
Additionally, the media aggregating node is provided with a device 83 for communicating with a media-ad muxer node, the device comprising a sender and a receiver arranged to obtain a list of advertisements based on the user information, and to forward a playlist of user-adapted advertisements and user-selected media content to the media-ad muxer node.
According to a further embodiment, the sender and the receiver of the device 83 for communicating with the media-ad muxer node is arranged to receive a notice that additional advertisement information is available, and the sender and the receiver of the device 81 for communicating with the external network-connected UE are arranged to forward the notice, and to receive a request to fetch the information from an advertisement logic server, and forward to the external network-connected UE.
The media-ad muxer node 10 creates a media-ad stream by fetching advertisements and media content from streaming servers (not illustrated in
The media-ad muxer node is further provided with a device 86 for communicating with the local network UEs, the device comprising a sender and a receiver arranged to receive a command to create a media-ad stream for the user-selected local network-UE, the stream comprising a user-selected media content and user-adapted advertisements. The device is further arranged to create the stream by fetching the advertisement and the media content from streaming servers, based on a playlist received from the media aggregating node, and to provide the stream to the user-selected local network-UE.
According to a further embodiment, the device 85 for communicating with the media aggregating node is arranged to send a notice that additional advertisement information is available, the information to be pushed by the media aggregating node to the external network-connected UE.
