Abstract

A full multimedia content is sent to end users from a network node (2; 2A). The end users select a respective personalized multimedia content from the full multimedia content and send a respective index associated with the respective selected personalized multimedia content to a network node (2; 2B) to trigger uploading of the respective selected personalized multimedia content or a version thereof on a social networking server (4) on behalf of the end users. The embodiments thereby enable end users to upload personalized multimedia content on their accounts at social networking servers (4) also in situations with limited uplink capacity by merely sending indices associated with the personalized multimedia content instead of the actual multimedia content itself.

Description

UPLOAD OF MULTIMEDIA CONTENT

TECHNICAL FIELD

The present embodiments generally relate to upload of personalized multimedia content to social networking servers, and in particular to upload solutions that are efficient also in limited upload capacity situations.

BACKGROUND

Social networks, such as Facebook, Instagram, and similar applications are part of the daily life for over a billion users worldwide. Some people even feel that they have not fully experienced an event in life until they have posted an image or a status update about the experience on a social network, may it be a wedding, a concert, a sport event or a daily meal.

When attending a public event such as a concert or a football game, many users post a photo from the event. However, it would be even more interesting to share pictures or video clips where they are visible attending such events so that they can prove that they were really there. This way the content the users share would also be more personalized. Perhaps the ideal "I was here" video would be a dolly shot taken by a camera that sweeps from the artist on stage, a sport field etc., moves over the audience and zooms in on the end user in the audience. This is called a "camera sweep" shot. These kinds of camera sweeps are impossible to create using mobile phones or tablets. On the other hand, the arena cameras are not able to provide a "selfie"-clip on behalf of the end user for the purpose of sharing on a social network.

Currently content, such as images, videos and audio, is uploaded from the users' smart phone or tablet via a communication network, such as a local area wireless network (WiFi) or a cellular network, to the social networking servers of the social media providers, for instance Instagram.

The traditional way of posting images and videos works fine most of the time when there is sufficient uplink capacity in the communication network. However, in some situations such uplink capacity may be scarce and limited. For instance, in an arena setting, such as at a pop concert or a football game, sufficient cellular or WiFi uplink capacity may not be available. The reason is that the communication network may be congested especially when almost every user wants to do the same thing, such as uploading a picture after a goal in a soccer game or posting a selfie to prove that he/she was really there. Such network congestion makes uploads impossible or at least significantly delays the uploading of taken pictures. Public events like concerts or sport events use advanced video camera solutions to capture the event from different perspectives. The cameras are used to capture the engagement from both the stage/arena and the audience and to enhance the experience of the event for audience on and offsite. Thus, there is a need for an efficient solution that enables the uploading of personalized pictures and other multimedia contents to social networking servers, for instance Facebook and Instagram. It is a particular need for an efficient solution that works also in places and situations where and when a large number of users want to perform such personalized multimedia content uploads.

DETAILED DESCRIPTION

Throughout the drawings, the same reference numbers are used for similar or corresponding elements.

Fig. 1 describes the traditional approach, where the end user takes a photograph or a video with his/her communication device 1 , such as mobile or smart phone, and uploads it over 3G/4G to Instagram's servers 4. For example, the end user may want to take a photo/video of himVherself (so-called "selfie"). The end user may also want to capture someone else and share it with the others - for example a celebrity sitting in a crowd or a friend. In this traditional approach, the multimedia content, here represented by a photograph, is uploaded over a mobile or cellular communication network to a network node 2, generally referred to as base station, Node-B or evolved Node-B (eNode-B) in the art, and forwarded to a social networking server 4, such as an Instragram server. This procedure generally works well under most conditions. However, in situations where a large number of end users are present within the same geographical area and several of them tries to upload multimedia content to social networking servers 4, there might not be sufficient uplink capacity to serve all end users and the communication network will become congested. A typical situation where this might happen is in an arena setting, such as at music or sports events. In such a case, several thousand or even several tens of thousands of end users could be present in the arena and would like to upload photographs or video clips taken with their mobile or smart phones 1 during the music or sports event. This high amount of uplink traffic, i.e. from the communication devices 1 to network nodes 2, will deplete the uplink capacity of the communication network causing congestion. As a consequence, several end users will experience long delays in uploading their multimedia content on the social networking server 4 or such uploading might be impossible due to the congestion.

The present embodiments solve such prior art problems by sending multimedia content to the communication devices 1 of the end users. The end users can then select a personalized multimedia content comprising at least one picture where a portion of a spectator is visible, from a received multimedia content, that he/she would like to upload on his/her account at the social networking server 4. According to one embodiment, the spectator is the end user himVherself, in which case the end user shares his/her "selfie" on a social network. Alternatively, the spectator may be another person whose picture the end user may want to share, for example a friend or a celebrity. The personalized content comprises at least one picture where a portion of the spectator is visible, where a portion may be e.g. a face, upper part of a body, or an entire body. Information on the selected personalized multimedia content, such as in the form of an index and identifier of the end user, is then uploaded, i.e. sent towards the network node 2 of the communication network, to trigger, i.e. cause or enable, uploading of the selected personalized multimedia content on or at the social networking server 4 on behalf of the end user. This means that only the index of the selected personalized multimedia content and the identifier of the end user at the social networking server need to be uploaded and not the actual personalized multimedia content itself. This significantly reduces the amount of data that the communication device 1 needs to transmit on the uplink to the network node 2 when uploading a personalized multimedia content on the social networking server 4 as compared to the prior art situation where the actual personalized multimedia content needs to be uploaded.

Accordingly, the risk of depleting uplink capacity and causing network congestion are significantly reduced according to the embodiments. Fig. 2 describes an embodiment of the proposed invention. The multimedia content, such as photos, video sweeps, etc., is taken by venue cameras 5. Examples of venue cameras are: crane cameras, cable cameras, handheld cameras operated by venue personnel, cameras on drones etc. In an arena setting, for example, these cameras may capture different parts of the arena, starting from the stage and moving towards the audience. The cameras may also be placed at the stage and capture the audience or different sections of the audience from a point of view of an artist performing on the stage.

Further on, each multimedia content, such as taken photo, is given an identifier (ID) or index to which an end user can refer to in case of selecting it. In case of a video, an ID or index can be a frame number. The multimedia content is subsequently downloaded to the communication device 1 , such as mobile phone, of the end user. This may be done, but is not limited to, by using broadcast or multicast, e.g. long term evolution (LTE) broadcast or multicast. The end user then makes a selection of a personalized multimedia content from the downloaded multimedia content that will be uploaded on his/her behalf on a social networking server 4. The ID or index associated with the selected multimedia content and an identifier of the end user at the social networking server 4 are uploaded via a mobile network and a network node 2 to a venue server 3, which could be in the form of a cloud server. The venue/cloud server 3 then uploads the selected personalized multimedia content, such as photo, associated with the received ID or index and the received identifier of the end user to the social networking server 4.

Multimedia Broadcast Multicast Service (MBMS) is a point-to-multipoint interface specification for mobile or cellular networks to provide efficient delivery of broadcast and multicast services both within a cell as well as within the core network. For broadcast or multicast transmission across multiple cells, MBMS defines transmission via single-frequency network configurations denoted multicast-broadcast single-frequency network (MBSFN). MBSFN is a communication channel defined in LTE. Enhanced or evolved MBMS (eMBMS) is the LTE version of MBMS and delivers services, such as mobile TV, using the LTE infrastructure. In eMBMS each TV program is only transmitted once in each cell even if there are several viewers of that program in the same cell. MBSFN is based on the principles of dynamic single frequency networks (DSFN), in which single-frequency networks (SFNs) are dynamically formed when groups of adjacent network nodes, e.g. eNode-Bs, send the same signal simultaneously on the same frequency sub-carriers. In effect, this makes the MBSFN transmission appear to an end user as a transmission from a single large cell, thereby dramatically increasing the signal-to-interference ratio (SIR).

Accordingly, eMBMS provides transport features for broadcasting the same content to all end users in a cell or multicasting the same content to a given set of end users in a cell using a subset of the available radio resources while the remaining radio resources are available to support of unicast services.

The transmission of the multimedia content to the communication devices 1 of the end users in order to enable the end users to select a personalized multimedia content to be uploaded on the social networking server 4 on behalf of the end user is preferably performed as a broadcast or multicast transmission, such as over a MBSFN channel from the network node 2. This means that the multimedia content is preferably sent as an eMBMS transmission, i.e. broadcast or multicast, from the network node 2 to the communication devices 1 , such as in the form of a LTE broadcast or multicast.

Although LTE broadcast or multicast are preferred examples of broadcast or multicast solutions to transmit the multimedia content to multiple, i.e. at least two, communication devices 1 in a given area, such as at an arena, the embodiments are not limited thereto. Actually, any broadcast or multicast solution that is capable of transmitting multimedia content to multiple communication devices 1 as disclosed herein can be used according to the embodiments.

In the case of a broadcast transmission, such as LTE broadcast, the same multimedia content is transmitted to all communication devices 1 that are present within the coverage area(s) of the network node(s) 2 performing the broadcast. Note that LTE broadcast can be performed by a single network node 2 or by multiple adjacent network nodes 2. In the latter case, these network nodes send the same signal simultaneously on the same frequency sub-carriers. In effect, this makes the broadcast transmission appear to a communication device 1 as a transmission from a single large cell. It is also possible to perform the transmission of the multimedia content to multiple communication devices 1 in the form of a multicast, such as LTE multicast. In such a case, the same multimedia content is transmitted to a group of communication devices 1 but not necessarily to all communication devices 1 that are present within the coverage area(s) of the network node(s) 2 performing the multicast. For instance, multicast could be directed towards communication devices 1 of end users having a subscription enabling them to receive multimedia content taken during, for instance, a music or sports event. The end users could, for instance, have bought a special or "gold" ticket to the music or sports event.

In the following, "full multimedia content" is used to denote the set or group of multimedia contents sent (e.g. by broadcasting or multicasting) to communication devices 1 from one or more network nodes 2. For instance, the full multimedia content could be in the form of multiple pictures taken or generated by a multimedia generating or capturing equipment 5, typically a camera. In such a case, the end user can select one or more of these pictures. Another example of a full multimedia content is a video stream or sequence. In such a case, the end user can select a picture or frame, i.e. a snap-shot, within the video sequence or stream or indeed select a sub-stream or sub-sequence of the video stream or sequence. A further example is a camera sweep, i.e. a video sequence taken by a camera moving along e.g. horizontal or vertical direction to capture a wide angle scene. For example, in an arena setting, a camera may capture a sweep by moving from e.g. the stage to the audience or part of the audience. In this case the full multimedia content may be the entire clip and the end user can select a sub-sequence that starts with the artist on the stage and ends with a frame where the user is visible. Yet another example of a full multimedia content is an audio sequence or stream, in which case the end user can select a sub-stream or sub-sequence of the audio stream or sequence, i.e. a portion of the audio stream of sequence, e.g. a clip of X s out of the Ys of the audio stream or sequence, wherein X<Y.

The social networking server 4 could be any server at which end users can upload multimedia content, such as pictures, video and/or audio. Non-limiting, but illustrative, examples include Facebook, Instagram, Vimeo, YouTube, Twitter, Flickr, Google+, Pinterest, Reddit, Vine, Kik, and Snapchat etc. The end user may specify in the application to which social network he/she wishes to upload the personalized multimedia content. The end user then preferably has an identifier (account or subscription) at the social networking service provider to allow the end user to upload multimedia content on his/her account at the social networking server 4. The identifier may comprise the user credentials, such as a user name and password. The identifier may also comprise the identifier of the social network itself, which is sent together with the user credentials to ensure that the personalized multimedia content is uploaded to the desired social network. For example, the identifier for Facebook may be "0", Instagram "1" etc.

The application could also be hardwired to one of the existing social networks. For example, the end users may have installed in their smartphones an application called "Arenalnstagram" that may look exactly like the regular Instagram application, but possibly with a different color of the icon. This application could be then specialized to upload only camera sweeps for example. In such a case, the identifier of the end user does not need to comprise the identifier of the social network itself.

Alternatively, social networks may have "arena functionality" built in. In this case the user does not need to choose social network, as this is done when opening the app. Fig. 5 is a flow chart illustrating a method for a communication device of an end user for uploading a personalized multimedia content to a social networking server according to an embodiment. The personalized multimedia content comprises at least one picture where a portion of a spectator is visible, where the spectator may be the end user himVherself or another person whose picture the end user may want to share (e.g. a celebrity or a friend). The spectator may be entirely visible in at least one picture of the personalized multimedia content, or it may be the upper part of his/her body, face etc The method comprises receiving, in step S1 , a full multimedia content from a network node. The full multimedia content may be, but is not limited to, broadcasted or multicasted from the network node. The method also comprises selecting, in step S2a, a personalized multimedia content from the full multimedia content based on a position of the spectator. The method further comprises sending, in step S3, an index associated with the selected personalized multimedia content to a network node and an identifier of an end user at the social networking server to trigger uploading of the selected personalized multimedia content or of a version of the selected personalized multimedia content on the social networking server on behalf of the end user.

With reference to Figs. 2-4, multimedia content generated by at least one multimedia generating or capturing equipment 5, such as at least one camera, at least one video camera, or at least one audio recorder, is provided to a venue server 3, where the full multimedia content is residing. The full multimedia content is provided to a network node arrangement of one or multiple network nodes 2, 2A, 2B, which sends (e.g. broadcasts or multicasts) the full multimedia content to receiving communication devices 1. The application can then select, based on a position of the spectator, a personalized multimedia content from or among the full multimedia content. An index or identifier associated with the personalized selected multimedia content, i.e. identifier of the selected multimedia content, and an identifier of the end user at the social networking server 4 are then uploaded from the communication device 1 to a network node 2, 2B of the network node arrangement. The index and the identifier of the end user could for instance be transmitted in the form of a message or command comprising the index and the identifier of the end user.

The personalized multimedia content is selected, by the application, from the full multimedia content based on a position of the spectator. Such a position may be manually specified in the application. For example, the end user may specify a seat number in the application. Alternatively, a ticket number may be provided as a manual input to the application. A position may also be obtained from GPS coordinates.

The position of the spectator may help to determine his/her position in each picture of the full multimedia content, i.e. it is possible to know exactly whether the spectator is visible in a frame, or if he is in the corner or center of the picture etc. With this information the personalized multimedia content can be stopped when the position of the end user starts getting further from a center of the picture of the full multimedia content. Alternatively, the personalized multimedia content can be stopped when the end user is no longer visible in the full multimedia content. An alternative is that the personalized video clip is slowed down to slow motion when the spectator is on the screen and that regular fast motion is resumed once the camera has passed the spectator. Yet an alternative is that the spectator gets highlighted, perhaps encircled or that he/she becomes brighter than the surrounding persons. In yet another embodiment the personalized video clip will zoom in on the spectator (typically by cropping the original video and scaling it to fill the screen) so that the spectator is in the center or closer to the center of the video.

Figures 6 (a)-(c) illustrate some examples on how the personalized multimedia content is selected based on the spectator's position where the spectator is the end user him/herself. The figures show an arena setting where a concert is taking place: there are a stage and an artist (A), audience in different sections of the arena and users of the mobile application (B, C and D). In the arena there may be a cable camera that covers the stage and different sections of the arena.

In these examples, the cable camera follows a predestined route, which means that the pixel positions of every seat for each frame of the full multimedia content may be known in advance, and stored in the application in the end user device such as a smartphone. The end user has previously entered his/her seat number in the application and after having received the low-quality version of the full multimedia content, the application can create a personalized multimedia content where the end user is centered when the camera closes in. The application also knows, for each seat number, where to stop the personalized multimedia content. As an example, for user B in Figure 6 (a), the personalized multimedia content will start in position marked with 1 , showing the artist A, and it will end in position marked with 2, showing the user B. For users C and D, however, the personalized multimedia content will start in position marked with 1 and end in position marked with 3. In order not to be too long and boring, this personalized multimedia content may artificially reduce the capturing frame rate, i.e., by dropping some frames, between positions marked with 1 and 2 to make the clip shorter. As an example, if every second frame in the full multimedia content is dropped between the positions marked 1 and 2, the movement from 1 to 2 will look like it is going at twice the speed compared to the movement between positions marked 2 and 3.

Figures 6 (b) and (c) show how the same end position can serve both users C and D. The position of e.g. user C is matched with the camera sweep corresponding to the full multimedia content. Now, by cropping out the left part of the image (dotted lines in Figure 6 (b)), the personalized multimedia content that user C gets will be centered on him/her. By cropping out the right part of the image (dotted lines in Figure 6 (c)), the personalized multimedia content that user D gets will instead be centered on user D. It should be understood that one will have to also crop the top/bottom parts of the frame in order to keep the aspect ratio constant, and not go from a landscape image to a quadratic or portrait video sequence all of a sudden. It should also be understood that the frame may need to be rescaled so that the individualized camera sweep video clip maintains the same resolution for all frames when played back. It should also be understood that if the spectator is in, for instance, the upper part of the frame, it may be desirable to crop out the upper part of the image so that the spectator is in the middle part of the screen also in the y-direction.

In Fig. 2 the index and the identifier of the end user are transmitted from the communication device 1 to the same network node 2 that conducted the broadcast or multicast of the full multimedia content. Figs. 3 and 4 illustrate another situation, in which the network node 2B that receives the index and the identifier of the end user from the communication device 1 may be different from the network node 2A broadcasted or multicasted the full multimedia content.

In Figs. 2 and 3, the network node 2, 2B receiving the index and the identifier of the end user forwards it to the venue server 3. In Fig. 4, the network node 2B instead forwards it to the social networking server 4, which in turn sends the index to the venue server 3. The venue server 3 can then use the received index in order to identify and select the personalized multimedia content associated with the index and selected by the end user identified by the received identifier of the end user. The venue server 3 transmits the selected personalized multimedia content and the received identifier to the social networking server 4, where it is uploaded on behalf of the end user identified by the received identifier.

This means that the end user is able to upload personalized multimedia content on his/her account at the social networking server 4 without the need for any transmission of the actual personalized multimedia content on the uplink from the communication device 1 to a network node 2, 2B within the communication network. In clear contrast, the communication device 1 merely needs to transmit the index and the identifier of the end user at the social networking server 4 on the uplink in order to trigger, cause or enable upload of the selected personalized multimedia content or of a version of the selected personalized multimedia content on the social networking server 4 on behalf of the end user.

The actual selected personalized multimedia content that is uploaded on the social networking server 4 could be the personalized multimedia content selected by the end user or a version thereof. Examples of the latter are further described herein but could include a processed version of the selected personalized multimedia content, such as a filtered or modified version of a picture, a version at a reduced frame rate, or a version at another quality than the one sent (e.g. by broadcast or multicast) by the network node 2, 2A and selected by the end user.

The index sent by the communication device 1 in step S3 of Fig. 5 could be sent as any index or identifier associated with the selected multimedia content. In the case of a set of pictures, the index could be a picture number of the selected picture within the set of pictures. Another example of index is a frame or picture number, e.g. picture order count (POC) value, of a selected frame or picture within a video stream. A further example includes an index in the form of a range of frame/picture or sample values, such as defining a video or audio sub-stream from frame/picture or audio sample number Zi to frame/picture or audio sample number Z2 within a video or audio stream. A related example is to have an index defining the video or audio sub-stream as corresponding to from Wi s to W2 s from the start of the video or audio stream. Yet another example is to include information on a portion of a picture to be cropped, as selected by the end user, for example a portion in a picture where he/she is visible. The portion may be characterized by the top left and bottom right coordinates in the picture, or top left / bottom right coordinates together with width and height of the selected portion or any other information that describes the portion selected. A further example is to include a frame rate for the selected video sub-stream. In that case, besides the selected start frame/picture number and the end frame/picture number, one can also choose at what frame rate the selected sub-stream is to be played. One may also specify different frame rates for different parts of the selected sub-stream. This means that the index may comprise more than a single data entity, such as frame or picture number, including a start frame or picture number or start audio sample number and an end frame or picture number or end audio sample number.

In an embodiment, the communication device 1 sends a command comprising the index of the selected personalized multimedia content and the identifier of the end user at the social networking server 4. This command could then be a message, such as of a defined message type, instructing the venue server 3 to identify a selected personalized multimedia content from the full multimedia content residing on or at the venue server 3 and forward the selected personalized multimedia content to the social networking server 4 where it is uploaded on behalf of the end user (see Figs. 2 and 3). Alternatively, the command could trigger the social networking server 4 to request the selected personalized multimedia content from the venue server 3 and then upload it on behalf of the end user (see Fig. 4).

The identifier of the end user at the social networking server could be any information that enables the social networking server 4 to identify the particular account for which it should upload the selected personalized multimedia content (version) received or requested from the venue server 3. The identifier could be present in a header or in a payload portion of the command or message that is compiled and sent by the communication device 1.

In an embodiment, step S1 comprises receiving the full multimedia content over a multicast-broadcast single frequency network (MBSFN) channel from the network node 2, 2A. Thus, in an embodiment step S1 comprises receiving the full multimedia content as an evolved multimedia broadcast multicast service (eMBMS) transmission, or broadcast or multicast from the network node 2, 2A. This corresponds to receiving the full multimedia content in step S1 as a long term evolution (LTE) broadcast or multicast from the network node 2, 2A. LTE broadcast or multicast, i.e. eMBMS transmission, using a MBSFN channel is an efficient way of sending content to all or selected portion of communication devices 1 within the coverage area of a network node 2, 2A or an arrangement of network nodes 2, 2A. As a consequence, only a subset of the available downlink radio resources need to be used to provide the full multimedia content to the communication devices 1 , thereby leaving remaining downlink radio resources available to support, for instance, unicast services.

In an embodiment, the communication device 1 comprises a social networking application running or implemented on the communication device 1 , for instance a Facebook or Instagram application (app). In such a case, step S1 of Fig. 5 preferably comprises downloading or streaming from the network node 2, 2A, the full multimedia content to the social networking application running on the communication device 1. Downloading or streaming may be, but is not limited to, performed by using a broadcast or multicast transmission.

In this embodiment, the end user is able to receive and view the full multimedia content on the social networking application implemented in and running on his/her communication device 1. For instance, the social networking application may trigger display of a message on the screen of the communication device 1 once the social networking application has received or is currently receiving the full multimedia content sent (e.g. broadcasted or multicasted) from the network node 2, 2A. The end user may then view the full multimedia content on the screen in order to select a personalized multimedia content from the full multimedia content based on the position of the spectator. In such a case, the social networking application preferably generates and sends the index associated with the selected personalized multimedia content to the network node 2, 2B and the identifier of the end user at the social networking server 4 to trigger uploading of the selected personalized multimedia content or of the version of the selected personalized multimedia content on the social networking server 4 on behalf of the end user.

Fig. 7 is a flow chart illustrating an additional, optional step of the method shown in Fig. 5. The method continues from step S2a. A next step S2b comprises receiving, from the end user, a selection of a multimedia processing operation for the selected personalized multimedia content. The method then continues to step S3 in Fig. 5, which comprises sending the index, the identifier of the end user at the social networking server 4 and at least one of a processing command and a parameter defining the selected multimedia processing operation to the network node 2, 2B to trigger uploading of a processed version of the selected personalized multimedia content processed according to the multimedia processing operation on the social networking server 4 on behalf of the end user. In this embodiment, the end user may process the selected personalized multimedia content and thereby upload not the original version of the selected personalized multimedia content as received from the network node 2, 2A but rather a processed version of the selected personalized multimedia content. The multimedia processing operation could be any picture processing operation, video processing operation or audio processing operation that is applicable to the relevant type of selected personalized multimedia content. For instance, the processing could be in the form of applying a filter to a picture, video or audio in order to achieve a desired picture, video or audio effect. As an example, Instagram uses different filters that an end user can select in order to get a filtered version of a photograph or picture. Other examples of multimedia processing operations include zooming in and out, cropping, adding effects such as blurring, etc. For example, by capturing the video at a high resolution, it is possible to crop and rescale the picture to produce the effect of (digitally) zooming in on the spectator. In this case, the end user may specify a portion of the picture to be cropped via the application, for example by drawing a rectangle around himVherself in the picture so that cropping is performed appropriately. This may add further personal touch to the selected multimedia content.

Another example of video processing operation is reducing a frame rate. For instance, if the full multimedia content is captured at a high frame rate, it is possible to drop every second frame at the beginning of the content where the stage/scene is captured, and to keep all the frames when the camera starts moving towards the spectator. This may give an effect of "slow motion" when moving towards the end user and may further add a personal touch to the content. To make the content even more personal, one may add one or more pictures/frames where e.g. the end frame of the selected personalized content is successively cropped for each subsequently added picture/frame and rescaled to produce the effect of zooming in on the spectator. The end user may also have a possibility to select a personalized content that would start at the stage, move towards the spectator, zoom in on the spectator, zoom out from him/her and move back towards the scene. In that case, the index of the selected content is created accordingly, by having the frames of the selected personalized content increasing up to the ending frame, with a possible repetition of the ending frame number if there are added frames where the end user is zoomed in, followed by the frame numbers in decreasing frame order down to the starting frame. This may also be combined with adding the video processing operations described above.

The multimedia processing operation is preferably performed on the selected multimedia content in the communication device 1 , such as using the previously mentioned social networking application running on the communication device 1. However, the resulting processed version of the selected multimedia content is not sent from the communication device 1 but rather information descriptive of the selected multimedia processing operation. This information is in the form of a processing command and/or a parameter. For instance, the processing command could define a frame rate reduction factor with respect to the original frame rate for different parts of the selected personalized multimedia content. The processing command could further define application of a filter whereas the parameter is an identifier of the selected filter. Correspondingly, the processing command could define a zooming action whereas the parameter defines the zooming level selected by the end user. In some situations the multimedia processing operation could be solely defined by a processing command, such as in the case where there is an alternative of not using a filter or using a single filter. In other situations it may be sufficient to define the parameter. For instance, when the parameter value defines a selected filter; in such a case, parameter value = 1 represents filter no. 1 , parameter value = 2 represents filter no. 2 and so on. In this case, parameter value = 0 represents no filter at all.

The processing command and/or parameter sent together with the index and the identifier of the end user to the network node 2, 2B thereby enables performing the multimedia processing operation at the venue server 3 on the selected personalized multimedia content defined by the index in order to get the processed version of the selected personalized multimedia content. This processed version is then uploaded on the social networking server 4 on behalf of the end user. Hence, these embodiments enable end users to select desired multimedia processing operations while still limiting the amount of uplink data that needs to be sent in order to upload multimedia content on social networking servers 4.

Another type of processing that can be done is to add text or other typed information to the selected multimedia content. In such a case, step S3 of Fig. 5 preferably comprises sending, to the network node 2, 2B, the index, the identifier of the user and text information entered by the end user on the communication device 1 to trigger uploading of the selected personalized multimedia content or of the version of the selected personalized multimedia content together with the text information on the social networking server 4 on behalf of the end user. This means that the end user can enter text information using his/her communication device 1 that will be uploaded together with the selected personalized multimedia content or the version of the selected personalized multimedia content. Examples of such text information include a tag of person or friend seen on a picture, text information defining the place at which the multimedia content was recorded, or any free text that the end user may want to add to the selected personalized multimedia content. Such text information can be represented with a low number of bits or bytes. Accordingly, sending the text information together with the index and the identifier of the end user merely results in a small increase in the bandwidth and the total amount of data that needs to be sent from the communication device 1 to the network node 2, 2B in order to trigger uploading of the multimedia content and the text information. The inclusion of text information can be combined with the previously described multimedia processing operation. In such a case, step S3 comprises sending, to the network node 2, 2B, the index, the identifier of the end user, the text information and at least one of the processing command and the parameter to trigger uploading of a processed version of the selected multimedia content together with the text information on the social networking server 4 on behalf of the end user. In an embodiment, step S1 of Fig. 5 comprises receiving a low quality version of the full multimedia content broadcasted or multicasted from the network node 2, 2A. In such a case, a high quality version of the full multimedia content is residing on the venue server 3. Step S3 then preferably comprises sending an index associated with a low quality version of the selected personalized multimedia content to the network node 2, 2B to trigger uploading of a high quality version of the selected personalized multimedia content on the social networking server 4 on behalf of the end user. This embodiment reduces the amount of downlink data that is sent as broadcast or multicast to the communication devices 1 of end users by sending a low quality version of the full multimedia content. This low quality version of the full multimedia content preferably has a lower bit rate as compared to the high quality version of the full multimedia content. This means that the low quality version will not take up so much bandwidth as compared to sending the high quality version.

The end user can then select among the low quality version of the full multimedia content on the communication device 1. However, even though the end user has selected a low quality version and the communication device 1 sends an index associated with the low quality version of the selected personalized multimedia content, the multimedia content uploaded on the social networking server 4 is the corresponding high quality version of the selected multimedia content.

The low quality version of the full multimedia content can be obtained by the venue server 3 according to various embodiments including, for instance, changing the quality be scaling resolution or by changing format.

This embodiment thereby not only significantly reduces the requirements for uplink capacity but also the requirements for downlink capacity in order to enable end users to upload multimedia content on social networking servers 4.

The above described embodiments of sending index and identifier of the end user, sending index, identifier of the end user and at least one of a processing command and a parameter, and sending index, and text information may be combined in various ways to send index and identifier, send index, identifier and at least one of a processing command and a parameter, send index, identifier and text information, send index, identifier, at least one of a processing command and a parameter and text information. Any of these combinations may additionally be combined by receiving a low quality version of the full multimedia content at the communication device but uploading a high quality version of the selected personalized multimedia content or of the version of the selected personalized multimedia content.

In an embodiment, the communication device receives feedback information, such as from a network node, representative of successful uploading of the selected personalized multimedia content or of the version of the selected personalized multimedia content. Such feedback information can thereby inform the end user that (the version of) the selected personalized multimedia content has been successfully delivered to the social networking server and has been uploaded on the account of the end user at the social networking server. For instance, the network node can send information or an update on the progress of transfer of the selected personalized multimedia content or of the version of the selected personalized multimedia content from the venue server to the social networking server. As an example, this information or update can indicate successful uploading. As another example, this information or update can be a session identifier and an indication of that the selected personalized multimedia content or the version of the selected personalized multimedia content was successfully delivered to the social networking server. In a further example, a number representing the percentage of bytes received so far by the social networking server of the selected personalized multimedia content or of the version of the selected personalized multimedia content could be sent to the communication device. This number is then typically between 0 and 100. In such a case, a fixed number, such as 100 or 101 , could represent successful delivery of the complete multimedia content at the social networking server whereas another fixed number, such as 255, is used to indicate failed delivery. In this case, the update or information could be regarded as progress information.

The information or update can be transmitted to the communication device using unicast. Alternatively, the information or update is transmitted to the communication device using multicast. Multicast can be more efficient since the number of bytes that is sent is small and a unicast radio bearer for each communication device is then not needed.

Fig. 8 is a flow chart of a method for a network node arrangement for uploading a personalized multimedia content to a social networking server according to an embodiment. The method comprises receiving, in step S10, a full multimedia content from a venue server. The full multimedia content resides on the venue server. The next step S11 comprises sending the full multimedia content to a communication device of an end user. Sending the full multimedia content may be performed by broadcasting or multicasting, but is not limited to these types of transmission. An index associated with a personalized multimedia content selected from the full multimedia content and an identifier of the end user at the social networking server are received in step S12 from the communication device. The received index and the received identifier are then sent in step S13 to trigger uploading of the selected personalized multimedia content or of a version of the selected personalized multimedia content on the social networking server on behalf of the end user identified by the received identifier.

The method of Fig. 8 is preferably performed by a network node arrangement. This network node arrangement could be in the form of a single network node 2 as shown in Fig. 2 or multiple, i.e. at least two, network nodes 2A, 2B as shown in Figs. 3 and 4. This means that the steps or operations shown in Fig. 8 may be performed by or in a single network node 2 or by or in different network nodes 2A, 2B within the network node arrangement.

The transmission of the full multimedia content in step S11 is preferably taking place to multiple communication devices present within the coverage area of the network node arrangement, such as present at an area or sports field.

In an embodiment, step S13 comprises sending the received index and the received identifier to the venue server or to the social networking server to trigger uploading, by the venue server, of the selected multimedia content or of the version of the selected multimedia content on the social networking server on behalf of the end user. Figs. 2 and 3 illustrate the former situation in which the network node 2, 2B forwards the received index to the venue server 3. Fig. 4 is illustrates the latter situation in which the network node 2B forwards the received index to the social networking server 4, which in turn sends the index to the venue server 3. The situation in Fig. 4 is particularly applicable if the communication device 1 of the end user has a social networking application implemented for receiving and displaying the full multimedia content and sending the index associated with the personalized multimedia content selected by the end user. In such a case, the social networking application could be implemented or preconfigured to communicate with the social networking server 4. This means that the transmission from the communication device 1 towards the venue server 3 is then taking place through the social networking server 4.

The sending of step S11 comprises, in an embodiment, broadcasting or multicasting the full multimedia content over a MBSFN channel to the communication device. In an embodiment, step S11 comprises broadcasting or multicasting the full multimedia content as an eMBMS transmission or as an eMBMS broadcast or multicast to the communication device 1. In a particular embodiment, step S11 comprises broadcasting or multicasting the full multimedia content as a LTE broadcast or multicast to the communication device. Step S12 comprises, in an embodiment, receiving the index, the end user identifier and at least one of a processing command and a parameter defining a selected personalized multimedia processing operation for the selected personalized multimedia content from the communication device. Step S13 then comprises sending the index, the received identifier and the at least one of the processing command and the parameter to trigger the venue server to upload a processed version of the selected personalized multimedia content processed according to the multimedia processing operation on the social networking server on behalf of the end user. In an embodiment, step S12 comprises receiving, from the communication device, the index, the identifier of the end user and text information entered by the end user on the communication device. In this embodiment, step S13 comprises sending the received index, the received identifier and the text information to trigger uploading of the selected personalized multimedia content or of the version of the selected personalized multimedia content together with the text information on the social networking server on behalf of the end user.

In an embodiment, step S11 comprises broadcasting or multicasting a low quality version of the full multimedia content to the communication device. In this embodiment, the full multimedia content residing on the venue server is a high quality version of the full multimedia content. In such a case, step S13 preferably comprises sending a received index associated with a low quality version of the selected personalized multimedia content to trigger the venue server to upload a high quality version of the selected personalized multimedia content on the social networking server on behalf of the end user.

Fig. 9 is a flow chart illustrating a method for a venue server for uploading a personalized multimedia content to a social networking server according to an embodiment. The method comprises sending a full multimedia content residing on the venue server to a network node in step S20. The following step

521 comprises receiving an index associated with a personalized multimedia content selected by an end user from or among the full multimedia content and an identifier of the end user at the social networking server. A multimedia content that corresponds to the received index is then selected in step

522 from the full multimedia content. The selected personalized multimedia content or a version of the selected personalized multimedia content and the received identifier are sent in step S23 to the social networking server to trigger uploading of the selected personalized multimedia content or of the version of the selected personalized multimedia content on the social networking server on behalf of the end user identified by the received identifier.

Hence, in a particular embodiment the venue server 3 is the entity that stores, internally or in a connected memory or server, the full multimedia content. The full multimedia content is provided to communication devices 1 of end users by means of the network node arrangement. In more detail, the venue server 3 sends the full multimedia content to at least one network node 2, 2A of the network node arrangement, which in turn sends (e.g. broadcasts or multicasts) the full multimedia content to the communication devices 1 as previously described herein. The venue server 3 receives the index of or associated with the multimedia content selected by the end user and the identifier of the end user at the social networking server 4. The index is typically either received from a network node 2, 2B of the network node arrangement, see Figs. 2 and 3, or from the social networking server 4, see Fig. 4. The venue server 3 thereby uses the received index in order to identify and select the particular multimedia content among the full multimedia content that the end user would like to upload on the social networking server 4. Once the venue server 3 has identified and selected the multimedia content the venue server 3 uploads it or a version thereof on the social networking server 4 on behalf of the end user.

Accordingly, in an embodiment step S21 comprises receiving the index and the identifier of the end user at the social networking server 4 from a network node 2, 2B or from the social networking server 4.

Fig. 10 is a flow chart illustrating an additional, optional step of the method shown in Fig. 9. In this embodiment, step S21 of Fig. 9 comprises receiving the index, the identifier of the end user and at least one of a processing command and a parameter defining a selected multimedia processing operation for the selected personalized multimedia content. The method then continues to step S22 where the multimedia content is selected using the received index. A following step S25 of Fig. 10 comprises processing the selected personalized multimedia content according to the multimedia processing operation defined by the received at least one of the processing command and the parameter to obtain a processed version of the selected personalized multimedia content. The method then continues to step S23 of Fig. 9, which comprises sending the processed version of the selected multimedia content to the social networking server and the received identifier to trigger uploading of the processed version of the selected personalized multimedia content on the social networking server on behalf of the end user. In this embodiment, the venue server not only identifies and selects the multimedia content that the end user would like to upload on his/her account at the social networking server. The venue server furthermore processes the selected multimedia content according to a multimedia processing operation as defined by the received processing command and/or parameter. This means that the venue server uses the received processing command and/or parameter in order to select the particular multimedia processing operation that should be applied to the selected personalized multimedia content in order to get the processed version of the selected personalized multimedia content. This processed version is then sent to the social networking server where it is uploaded on behalf of the end user.

In an embodiment, step S21 of Fig. 9 comprises receiving the index, the identifier of the send user and text information entered by the end user on the communication device. In such a case, step S23 preferably comprises sending the selected multimedia content or the version of the selected multimedia content, the received identifier and the text information to the social networking server to trigger uploading of the selected personalized multimedia content or of the version of the selected personalized multimedia content together with the text information on the social networking server on behalf of the end user.

In an embodiment, the full multimedia content residing on the venue server is a high quality version of the full multimedia content. In this embodiment, step S20 comprises sending a low quality version of the full multimedia content to the network node. Step S22 preferably comprises selecting a high quality version of a multimedia content that corresponds to the received index from the high quality version of the full multimedia content. This high quality version of the selected personalized multimedia content is then sent in step S23 to the social networking server to trigger uploading of the high quality version of the selected personalized multimedia content on the social networking server on behalf of the end users.

The venue server thereby has access to the full multimedia content in a high quality version and in a low quality version. The low quality version is sent to the network node and further on to the communication devices of the end users. This means that the bandwidth and the downlink radio resources needed to send (e.g. by broadcast or multicast) the full multimedia content to the end users can be significantly reduced by providing the low quality version of the full multimedia content instead of the high quality version of the full multimedia content. The end users thereby perform the selection among the low quality version of the full multimedia content. However, once the venue server receives indices associated with the respective selected multimedia content it identifies, selects and sends the corresponding high quality version of the respective selected multimedia content. This means that the version of the selected personalized multimedia content that the social networking server receives and uploads on behalf of an end user is the high quality version of the selected personalized multimedia content.

Fig. 11 is a flow chart of a method for a social networking server for uploading a personalized multimedia content according to an embodiment. The method comprises receiving, in step S30, an index associated with a multimedia content selected by an end user from a full multimedia content residing on a venue server and an identifier of the end user at the social networking server. The received index and the received identifier are sent to the venue server in step S31. A following step S32 comprises receiving the selected multimedia content or a version of the selected multimedia content from the venue server. The selected multimedia content or the version of the selected multimedia content is then uploaded in step S33 on behalf of the end user identified by the received identifier. In an embodiment, steps S31 and S32 thereby comprise requesting the selected personalized multimedia content or the version of the selected personalized multimedia content from the venue server based on or using the index.

This embodiment of the method thereby corresponds to the situation as shown in Fig. 4, in which the social networking server 4 receives the index and uses it to request the selected personalized multimedia content or the version thereof from the venue server 3. The social networking server 4 then, once it has received the multimedia content from the venue server 3, uploads it on behalf of the end user.

Fig. 12 is a flow chart of a method for a social networking server for uploading a multimedia content according to another embodiment. The method comprises receiving a selected personalized multimedia content from a venue server at which the multimedia content is selected from a full multimedia content residing on the venue server.
