Description

Video system

FIELD OF THE INVENTION

The invention relates to a video system, a system for providing multi-media content to a display device comprising a video system and a method of providing multimedia content to a display device.

BACKGROUND OF THE INVENTION

In recent years, television systems have become more advanced. More features have become available. In order to make use of many different broadcasting media, different analog and digital broadcasting systems are being used. Such broadcasting media include terrestrial air, cable, and satellite. Such broadcasting systems include the traditional analog terrestrial air, cable, and satellite broadcasting systems, as well as digital video broadcasting (DVB) systems. Recently also digital systems based on ADSL technology have been developed for broadcasting television content via analog telephony networks. Most televisions do not support all these broadcasting systems. Instead, a subscriber to a particular broadcasting system uses a set-top box that is responsible for converting the broadcast signal into a video signal (e.g. SCART) that is compatible with the television.

Such set-top boxes sometimes provide more functionality than just converting a single channel of a broadcast programming signal into a video signal. An example of a set- top box allows a user to receive different television channels and radio channels. It also has a hard disk to store video programs and to enable live pausing and replaying of television programs. Also, the system allows a user to watch selected programs that have been broadcast during the past 10 days, as well as video on demand programs. The system also provides an electronic program guide (EPG) for providing the user with a current overview of programs to be broadcast. The EPG may be sent with the broadcasting signal and contains information about the channels made available by the broadcaster. These known systems are also capable of supplying additional multi -media content on top of the regular programs shown on the broadcasted channels. The additional multi-media content, such as advertisements, may be shown in the form of commercial breaks interrupting a program watched by a viewer, or as an overlay such as a ticker tape or a Picture in Picture during the watching of a program.

The known methods of presenting additional multi-media content have however some disadvantages. The content presented is not very well targeted to the individual user. It is incorporated in the broadcast signal and will reach all users that are tuned to a particular channel, without taking into account an individual's preference or user history. Further, the additional content is presented at moments that can be inconvenient to the viewer. The presence of, or interruption by the additional content disturbs the watching experience of the viewer.

SUMMARY OF THE INVENTION

It is an object of the invention to reduce or eliminate at least one of the drawbacks to the known systems and to provide a system and a method for providing multimedia content to a display device. The video system for providing multi-media content to a display device, comprises: a first control input for selecting program content to be rendered; an output for providing a video signal for rendering on a display; a controller for including the selected program content into the video signal; means for including first additional multi-media content in the video signal in addition to the selected program content; a second control input for selecting second additional multi -media content to be rendered, wherein the second additional multi-media content is related to the firs.t additional multi-media content; means for including the second additional multi-media content in the video signal upon receiving a selection by the user of the second additional content; wherein the means for including the first additional multi-media content is arranged for including the first additional multi-media content into the video signal in response to the reception of the selection of program content via the first control input.

The system provides a new way of interaction between a user and a video system. When the user selects program content he or she would like to consume, the system provides the selected program. But in addition, first additional multi-media content is being rendered to bring some particular information to the attention of the user. For example, the first additional content comprises a news headline, a brief weather forecast, a sports result, a stock quote, or an advertisement. In addition, the user is given the option to select and display second additional multi-media content, which relates to the first additional multi-media content. This way, when the first additional information, brought to the attention of the user without his specific request, triggers the user's interest, the user may obtain more related information by selecting to see the second additional content. The improved video system will present the additional multi-media content at the moment when the user is switching channels or programs, i.e. at the moment the user is most susceptible to new content. Further, the system provides the user a direct link to further related (second) multi-media content.

The system has a greatly simplified user interface. In existing systems, including electronic program guides, the user has to browse manually through the available information. This requires navigating through menus or through different pages or channels of content, while looking for the required information. In the proposed system, the user is automatically presented with additional content items, and only needs to select to render more related content whenever appropriate. Because navigating through menus or different pages or channels of content is not needed to access the first and second additional content, the user interface can be greatly reduced and the user experience is enhanced. The user needs to do nothing until the information relevant to him is presented automatically. Meanwhile, he can consume his selected content uninterrupted.

The system is particularly suited to bring under attention of the user a relatively large number of topics (by means of first additional content items), only a few of the topics being of interest to the user, where it is not known a priori which of the content items will be of interest to the user. The user is only bothered to the least possible extend as he can enjoy selected content simultaneously to a rendering of the topics.

The system provides an improved way of browsing through information. The user is not interrupted for a presentation of the additional content. Instead, both the selected content and a first portion of the additional content are presented. This means that the user can enjoy his selected content, and at the same time notes the first portion of the additional content. He then has the option whether to see the second portion of the additional content (which is related to the first portion of the additional content). If he believes, based on the first additional content, that the relating second additional content is not of interest to him at the moment, the user does not have to do anything and is not bothered any more. His presentation of the selected content is not interrupted. If he decides to consume also the second additional content, he can easily select to see it. One of the advantages is that the system finds out about the interests of the user without bothering him. His selection of the second additional content indicates he is interested; his refraining from selecting the second additional content indicates he is not interested. The home entertainment system may for example be implemented in a television. The video system may also be implemented as a set-top box to be used in conjunction with a display device. These two configurations are examples of entertainment systems. Such entertainment systems may comprise for example a display (usually as part of a display device), a surround sound system, a video recorder, and a set-top box.

In an embodiment, the video system comprises a set-top box for use in a home entertainment system. This makes the system especially user friendly and economic to realize.

In one embodiment, the means for including the first additional content is arranged for also including in the video signal, together with the first additional content, an indication of a possibility to select the second additional content via the second control input. The indication makes it easier for the user to remember that he may select the second additional content relating to the first additional content for rendering.

In one embodiment the first additional content may be included in the video signal for a predetermined period of time or, in another embodiment, on regular time intervals.

An embodiment comprises means for replacing the first additional content regularly. By regularly replacing the first additional content with new content, it becomes possible to provide current information that is subject to change, such as stock quotes, special offers, whether forecasts, and news items. The content can be refreshed via an information provider connected to the video system via a network such as the Internet or a TV cable or ADSL network. hi an embodiment, the controller for including the selected content and the means for including the first additional content are arranged for using at most one third of the area of a display for the first additional content, and at least half of the area of the display for the selected content. The content selected by the user is dominant in the video signal, therefore at most one third of the display is used for rendering the first additional content. It enhances the user viewing experience.

In an embodiment, the means for including the first additional content is arranged for including the first additional content as an overlay on top of the selected content in the video signal. This helps to avoid an irritation of the user because his selected content is presented as the most important information, the first additional information being only presented in an overlay. In an embodiment, the means for including the second additional content is arranged for including the second additional content as a substantially screen-filling presentation in the video signal. Because the second additional information is explicitly selected by the user, it is justified to use substantially the complete frame (i.e., the substantially complete display area) for its presentation, using the substantially the full display, substantially replacing the presentation of the originally selected content. Preferably, the originally selected content continues to be displayed in a small window (e.g. picture-in- picture).

An embodiment comprises an input for receiving a broadcast programming signal, where the content available for being selected to be rendered via the first control input includes a plurality of channels of the broadcast programming; and a stream selector for providing the selected channel for inclusion into the video signal under control of the controller. This is useful because it allows the video system to be used in combination with broadcast programming. An embodiment comprises a storage medium reader, where the content available for being selected to be rendered via the first control input includes at least one content item available via the storage medium reader, the storage medium reader being arranged for providing the selected content item for inclusion into the video signal under control of the controller. This is useful because it allows current information in the form of first and second additional information to supplement the fixed content on the storage medium.

An embodiment comprises an electronic program guide, where the content available for being selected to be rendered via the first control input includes data items in the electronic program guide; the electronic program guide being arranged for providing the selected data items for inclusion into the video signal under control of the controller. This allows for a more feature-rich electronic program guide.

An embodiment comprises an output for transmitting a background request to a server for the first additional content, the request comprising an identifier of the selected content; and an input for receiving the requested first additional content to be included in the video signal. Preferably the request also comprises user information.

Another embodiment comprises an output for transmitting a request to a server for the second additional content upon receiving the selection of the second additional content; and an input for receiving the requested second additional content to be included in the video signal. Requesting and receiving the first and/or second additional content at the moment it is needed enables an external entity, such as a content provider or server, to determine the additional content. This facilitates remote control of the additional content, which makes it easier to keep the content up-to-date and to provide a relatively large number of content items.

In a further aspect, the invention relates to a system for providing multi-media content to a display device, wherein the system comprises a video system as described above and a server system. The server system comprises: an output for transmitting a first additional content to a video system for inclusion in a video signal together with content selected by a user of the video system; an input for receiving a request for second additional content, the request being transmitted by the video system upon receiving a selection by the user of the second additional content; and an output for transmitting the requested second additional content to the video system for inclusion in the video signal.

In one embodiment the server system further comprises an input for receiving a request for the first additional content, the request being transmitted by the video system upon receiving a selection of content to be rendered, and the request comprising an identifier of the selected content. In addition, in another embodiment, the server system may comprises an output (758) for transmitting video broadcast programming comprising a plurality of channels available for selection by the user the video system. In a further embodiment the server system further comprises: a user database server comprising user information, preferably keywords reflecting the interests and/or needs and/or preferences of the user; an application server connected to the user database capable of providing upon request the video system with the user information and an electronic programming guide, preferably a mini electronic programming guide, comprising detailed information on the selected program content selected by the user of the video system; a campaign manager server comprising references to the first and second additional multimedia content; one or more content servers comprising the first and second additional multimedia content. Using the electronic programming guide of the application server does not require the system to use of the electronic programming guide provided by the broadcaster via the broadcast signal.

In yet another embodiment the campaign manager server is capable of selecting appropriate first additional multi media content on the basis of the user information references to first and/or second additional multi-media contents which reflect the interests and/or needs and/or preferences of the user. In an embodiment the campaign manager server is capable of registering the selection of second additional multi-media content.

In an embodiment the application server and user database server are capable of registering and logging the selection of first and second additional multi-media content. In yet another aspect the invention relates to methods of providing multimedia content to a display device. In one embodiment the method comprises the steps of: selecting program content to be rendered; providing a video signal for rendering on a display; including the selected program content into the video signal; including first additional multimedia content in the video signal in addition to the selected content in response to selecting the program content; selecting second additional content to be rendered, wherein the second additional content relates to the first additional content; and including the second additional multi-media content in the video signal upon receiving a selection by the user of the second additional content.

In another embodiment the method of providing multi-media content to a display device comprises the steps of: receiving program selection information; retrieving - in response to the reception of the program selection information - first additional multimedia content; transmitting a video signal to the display device for displaying the first additional multi-media content in a first sub-area of the screen of the display device; transmitting a video signal to the display device for displaying in a second sub-area of the first sub-area, an indication allowing a user - upon selection of the indication - to retrieve and display the second additional multi-media content, wherein the second addition multimedia content is related to the first addition multi-media content.

In an embodiment the method may further comprise the step of: transmitting - in response to the reception of the program selection information - a request to a server for retrieving the first additional content. Further, in yet another embodiment the request comprises user information.

The invention further relates to a content providing unit for providing multimedia content to a display device. In one embodiment the unit comprises: means for receiving program selection information; means for retrieving - in response to the reception of the program selection information - first additional multi -media content; means for transmitting a video signal to the display device for displaying the first additional multimedia content in a first sub-area of the screen of the display device; means for transmitting a video signal to the display device for displaying in a second sub-area of the first sub-area, an indication allowing a user - upon selection of the indication - to retrieve and display the second additional multi-media content, wherein the second addition multi-media content is related to the first addition multi-media content.

In one embodiment the content providing unit may comprise means for transmitting - in response to the reception of the program selection information - a request to a server for retrieving the first additional content. In another embodiment the request may comprise user information.

1. The invention further relates to a display device, preferably a television, a personal digital assistant, a mobile phone, a set-top box or a computer comprising a video system or a content providing unit as described above and to a computer program product directly loadable into an internal memory of a computer comprising software code portions for performing the steps as defined in the methods as described above, when the product is run on a computer.

The invention will be further illustrated with reference to the attached drawings, which schematically show embodiments according to the invention. It will be understood that the invention is not in any way restricted to these specific embodiments.

Figure 1 illustrates aspects of an exemplary television broadcasting system. It illustrates an antenna 106. The antenna 106 receives broadcast programming from a broadcaster. The signal received by the antenna 106 comprises a plurality of program channels. A TV tuner 108 is connected to the antenna 106 via a coax cable. The TV tuner is connected via a digital USB connection with a set-top box 116. The set-top box also has an IP network connection to connect to the Internet 104 via an internet gateway 120. Via the Internet 104, the set-top box 116 also can connect to a datacenter comprising a server system 102. The set-top box 116 produces a video signal for rendering on display device 118. The video signal is provided to the display device via a SCART interface. A remote control 112 is used to control operation of the set-top box 116. The set-top box 116 and the TV tuner 108 are integrated into a single unit 120. The display device may be a television, a personal digital assistant (PDA), a mobile phone, a computer or any other device suitable for displaying the broadcast signal to the user. Figure 1 is only intended to provide an illustrative context in which the features disclosed herein may be applied. It is not intended to be limiting in any way. The TV tuner and the set-top box may also be provided separately, and the TV tuner may also be connected to a satellite dish, a cable network or an ADSL connection instead of or in addition to the antenna. The functionality of the separate units shown in the Figure may be combined in a single unit, or may be distributed over several units in a different way. Also, the connections to external networks via the antenna 106 and the Internet 104 are only examples and may be replaced by any other communications means. The SCART interface may be replaced by other connectors such as DVI or HDMI.

Figure 2 illustrates some of the features provided by the set-top box 116. These features are controlled by a user via the remote control 112, 206. The screen shot 208 shows a menu 210 with some content categories such as: Personal, Local content, Themes, and an electronic program guide. The user can navigate through these categories using up/down arrows and OK button 204. Content items 212 appear on the right hand side of the screen shot 208. Here the content items in the selected category "I)" are displayed. Using the button 202 on the remote control 206, the user can switch to a TV channel. A particular channel can be selected by using numeric keys 214 available on the remote control 206.

Figure 3 shows a first exemplary screen layout 308 of a selected channel. At the same time that the channel content is rendered on the display device 118, some information about the channel programming (e.g. a title of the current show) is provided in box 304. The box also contains first additional multi-media content 310. The additional multi-media content may be information in any multi-media form, i.e. text and/or static or moving graphics and/or sound. Below or in the vicinity of the first additional multi-media content, a button 312 is displayed in a specific, predefined color, for example red, next to a short line of text indicating the presence of second additional multi-media content which relates to the first additional content 310. This is to indicate to the user that pressing a corresponding red button 302 on the remote control 306 will provide second additional multimedia information relating to the first additional information. When the user presses a corresponding red button 302 on his remote control 306, he is selecting second additional multi -media content, where the second additional content is relating to the first additional content. For example, the first additional content 310 comprises a logo of an animal channel or an image of an animal. The text 314 comprises the name of a TV channel or slide show about animals.

Figure 4 shows the second additional multi-media content in screen shot 408, which may represent a slide show about animals. The slide show content is retrieved by the set-top box 116 from the server system 102. The page is rendered after the user presses the red button 302. The originally selected channel content, which was previously shown in fullscreen 308, now is rendered in a small box 208.

Figure 5 shows another exemplary screen layout 508 and of the remote control 506. The screen display comprises electronic program guide information 504. First additional multi-media content 510 is shown near the bottom of the screen, together with an indication 512 of a button on the remote control 506 that the user can press to see second additional multi-media content relating to the first multi-media content. The first additional information 510 may comprise a company logo. Figure 6 shows a screen layout comprising second additional multi-media content relating to the first additional multi-media content 510. This screen is provided to the user after pressing the button 502 indicated by indicator 512 in Figure 5. The screen 608 may comprise an advertisement about some of the products of the company corresponding to the company logo 510. Figure 7 illustrates a system for providing multi-media content to a display device comprising a video system 700, a server system750 connected to the video system 700 via a network 774 and a display device 770 which may be connected to the video system via a video connector, a remote control 776 communicating with the video system 700 via infrared communication, and a broadcaster 772 sending video content in a plurality of channels via a medium (e.g. DVB-T, or a cable television network) to the video system 700. The video system 700 comprises a first control input 702 for selecting program content to be rendered. The user sends commands to the first control input 702 via the remote control 776. Upon receiving the command to select for example a channel of content, the input 702 passes the command to a controller 706 which then includes the selected program content in a video signal that is provided to the output 704 for rendering on a display device 770.

The video system 700 also comprises a means 708 for including first additional multi-media content in the video signal in addition to the selected program content. The first additional multi-media content may be different from the selected program content. The first additional content may however also relate to the selected program content. It may, for example, represent more detailed information about a topic currently being rendered. Alternatively, the first additional content is unrelated or only slightly related to the selected content. For example, the first additional content may comprise an advertisement for some product, or it may comprise a hint for a user that some information has become available, for example that a breaking news story is about to start on another channel.

The video system 700 also comprises a second control input 710 for selecting the second additional multi-media content to be rendered. For example a button 778 on the remote control 776 is dedicated for selecting the second additional multi-media content. This allows a one-click selection of the second additional content. The control signal corresponding to the button 778 is sent by the remote control 776 to the second control input 710. The video system 700 also comprises a means 712 for including the second additional multi-media content in the video signal upon receiving the selection by the user.

The video system 700 may be implemented as a functional unit, such as a content providing unit, which can be inserted in a television set, a computer, or a personal digital assistant or in a separate set-top box.

Preferably the first additional multi-media content is shown to the user via the output 704 and the display device 770 immediately or shortly after receiving the selection of content to be rendered via the first control input. The first additional multi-media content may be displayed together with meta information about the content being rendered (for example channel name, program title, title and start time of next program). The additional content may also be displayed at for example regular time intervals. The system also comprises means 714 for replacing the first additional content regularly. The first additional content is dynamic. It can be replaced every time it is displayed (i.e. every time after receiving the selection via the first control input), or the first additional content can be the same every time the selection via the first control input 702 is made during a particular predetermined time interval. The first additional content items may be provided by the broadcaster 772 or by the server system 750.

The means 708 for including the first additional multi-media content may also include an indication for the user to select the second additional input for rendering. The selection is performed via the second control input 710 and the button 778 on the remote control 776. For example, the first additional multi-media content includes the indication. Alternatively, a separate indication is displayed next to the rendering of the first additional content or a predetermined sound is included in the video signal for rendering. At most one third of the screen area is used by the means 708 for the first additional multi-media content, and at least half of the screen area is used by the controller 706 for the selected content. For example, a bar or a small rectangular region near the bottom of the screen is used for the first additional multi -media content. The combination of the two content types by the means 708 and the controller 706 into a single video signal is realized by means of known digital and/or analog video processing. For example, known overlay techniques are used to include the first additional multi-media content as an overlay on top of the selected content in the video signal. The second additional multi-media content, included by the means 712, is a substantially screen-filling presentation. The program content originally selected via the first control input 702 is disregarded or is rendered in a relatively small area of the screen.

The video signal 704 selected via the first control input 702 is provided by means of video broadcaster 772 to a broadcast programming input 716 of the video system. This may be an analog or digital signal received via an antenna or cable, or it may be one or more digital video streams provided via an IP network and/or a DSL network. The server system750 may contain the broadcaster 772 thereby forming a IPTV platform. The broadcast programming signal 716 makes available a plurality of channels to be selected for rendering via the first control input 702. The controller 706 sends a corresponding control signal to a stream selector 718 which parses the signal received by input 716 to extract the selected channel content and which provides the extracted content to the video output 704. The video system 700 also comprises a storage medium reader 720. This storage medium reader 720 may comprise a hard disk for temporarily storing content received via the input 716 from the broadcaster 772. The storage medium reader 720 may also support removable media such as DVD's. The first control input 702 is used to select content items available via the broadcast programming input 716 and/or via the storage medium reader 720. If an item is selected from the storage medium reader 720, it starts processing the selected item and provides the corresponding video signal to the video output 704. The selected content item is accompanied by first additional content.

The video system also comprises an electronic programming guide (EPG) 722. The EPG may obtain broadcast programming information from the broadcaster 772 and/or the server system 750. Preferably the EPG is obtained from the server system. The EPG is used to browse and select an interesting content item for rendering. Thus, the content items available for being selected to be rendered via the first control input 702 includes data items in the electronic program guide. Such data items may include textual information as well as still images and trailers of TV programs. Upon selection of such a data item, the means 708 may include first additional multi-media information into the output signal provided by the video output 704. This first additional information is presented on the display 770 together with the requested data item.

The video system 700 comprises an output 724 for transmitting a background request to a server for the first additional content, the request comprising an identifier of the selected content. This request is sent upon receiving the selection of content via the first control input 702. The request may also be sent at regular time intervals. The requested first additional content is received from the server 750 via an input 726 for inclusion in the video signal. The request may also comprise user information such as a zip code, a smart card number, a name and address of the user. The output 724 is also used for transmitting a request to a server for the second additional content. This can be done upon receiving the selection of the second additional content, or in the background before receiving the selection of the second additional content. The input 726 is also used for receiving the requested second additional content to be included in the video signal. The first additional content comprises for example an image or text or a movie. The second additional content comprises for example a TV channel, a website, a photo, a slideshow, or a video.

The server system 750 comprises an output 752 for transmitting a first additional content to the video system 700 for inclusion in a video signal together with content selected by a user of the video system. The server system 750 also comprises an input 754 for receiving a request for second additional content. The server system 750 also comprises an output 756 for transmitting the requested second additional content to the video system for inclusion in the video signal upon receiving the request. The input 754 also receives the request from the video system 700 via the network 774 for the first additional content. The server system 750 also comprises an output 758 for transmitting video broadcast programming comprising a plurality of channels available for selection by the user the video system. This output 758 can be used instead of or in addition to the broadcaster 772. The server system 750 can be implemented for example in a single high-end computer or in a computer farm comprising a network of a plurality of servers. Figure 8 illustrates processing steps of an embodiment that comprises selecting 802 program content to be rendered; providing 804 a video signal for rendering on a display device; including 806 the selected program content into the video signal; including 808 first additional multi-media content in the video signal in addition to the selected program content in response to selecting the program content; selecting 810 second additional multi-media content to be rendered, wherein the second additional multi -media content relates to the first additional multi-media content; and including 812 the second additional content in the video signal upon receiving a selection by the user of the second additional content. These program steps may be implemented in a computer program.

Figure 9 illustrates an exemplary embodiment of the server system 750. The server system 750 in this embodiment comprises a number of servers with different functionality. A user database server 900 comprises data relevant for selecting and providing the first additional multi-media content to a specific user. Such data may be stored in a user profile containing specific user information necessary for selecting multi-media content which is dedicated to specific interests and/or needs of the user. This profile may also contain a logbook that specifies the user usage history, such as his previous selections of second additional multi-media content. The user database server can also contain a table with keywords. These keywords may be provided by the user or by other sources and can be used by the system 750 to select relevant multi -media content. An application server 910 is connected to the user database server and is capable of retrieving upon request user data from the user database server. Based on all the user data, the application server can determine and select the appropriate keyword(s) to be used in the process of retrieving first additional multi media content, each time a request for first additional multi media content is received. These keywords may reflect the interest and/or needs and/or lifestyle of a particular user. Further, the application server is capable of providing an electronic program guide (EPG). A web server 920 connects all set-top boxes to the application server. The web server can be further connected to a campaign manager 930, and one or more content servers, which may comprise an internal content server 940, owned by the owner of the content providing system, and/or an external, third party content server 950. The campaign manager server has a database comprising all references to first and secondary additional content. These references may be in the form of URL's or one or more IP tables comprising the IP addresses of the servers comprising the additional content. The content servers contain the multi-media content to be displayed on the display devices.

Figure 10 regards a further embodiment of the video system 700 implemented in a set-top box (STB) and schematically shows an exemplary flow of the process within the set-top box when selecting a channel (zapping).

The set-top box is connected via a television tuner to a broadcast signal comprising the channels provided by the broadcaster and, optionally, to the Internet. The set- top box is further connected to the server system 750 and a display device. The set-top box comprises a controller allowing the user to control (e.g. start/stop/pause) the multi-media streams of the broadcast signal or any other Internet sources. The controller may use a media player to control the streaming. The controller is further capable of requesting the television tuner to change to another channel provided by the broadcast signal or any other internet source. The controller may be handled by the remote control actions of the user. In a first step of the scheme according to Figure 10, the user sends via the remote control program selection information, e.g. in the form of a zap action, to the controller of the set-top box. In response to the reception of the program selection information, the controller sends - in a second step - a signal to the television tuner for setting the channel to the channel requested by the user and a request to the server system 750. This request may have the form of an HTTP request. In response to the request the server system 750 provides the set-top box - in a third step - with a signal which may comprise a dedicated electronic programming guide, which may have the form of a mini electronic programming guide, containing detailed information about the newly selected channel. The signal further comprises first additional multi-media content, which may contain information which is dedicated to the specific interests and/or needs of the user of the set-top box . In a fourth step the controller merges the broadcast signal of the selected program channel with the signal provided by the server system. In a fifth and last step the merged signal is displayed by a display device.

Figure 11 illustrates an embodiment that exemplifies in more detail the retrieval of first additional content as discussed in relation with Figure 10. This figure schematically illustrates the steps how the first additional multi-media content is retrieved from the server system. When a zap action is performed by the user (e.g. by pressing a channel selection button of the remote control), the controller of the set-top box will automatically send in a first step a request for a mini electronic programming guide to the web server 920. Preferably the request may comprise information about the user and the channel. The web server, which acts as a gateway between the set- top box and the application server, forwards the request in a second step to the application server 910. In a third step, the application server and the user data base server respond to the request by providing web server with the relevant electronic programming guide or a mini guide and a set of keywords. The web server subsequently forwards the guide and the keywords in a forth step to the set- top box. The relevant electronic programming guide data are stored in the application server and are updated via a daily EPG feed from several sources. The set of keywords are based on user specific information stored in the user database server. In a fifth step the set-top box sends in response to the reception of the electronic programming guide data and the set of keywords a request to the campaign manager server 730. The request to the campaign manager comprises one or more keywords of the set of keywords received by the set-top box. The campaign manager server may be owned and managed by the owner of the server system 750 or may be a third party campaign manager server.

In a sixth step the campaign manager server extracts on the basis of the keywords location information of (part of) the first additional multi-media content and sends this location information to the set-top box. The campaign manager server may also provide a part of the first additional multi-media content. The set-top box subsequently retrieves in a seventh step (a part of) the additional multi-media content from a source indicated by the location information by sending a request to the content server referred to in the location information. The content server may be owned and managed by the owner of the server system 750 or may be a third party content server. The content server transmits in a eighth step (part of) the first additional content to the set-top box. The set-top box thereafter merges the first additional content received with the broadcast signal comprising the selected program content.

Figure 12 illustrates an embodiment that exemplifies in more detail the retrieval of second additional content as discussed in relation with Figure 10. Figure 12 schematically illustrates the steps how the second additional multi-media content is retrieved from the server system.

The sequence of events is triggered by the user pressing the remote control button 302 associated with the first additional content. In a first step the controller of the set- top box will send a request for the second additional content to the campaign manager server 930. The request allows the campaign manager system to register that the user has requested second additional content. This way the campaign manager server is capable of registering click rates for specific campaigns or advertisements. In response to the request the campaign manager sends in a second step location information of the second additional multi-media content to the set-top box. In a third step the request is redirected to a third party content server, which - in a forth step - sends the selected multi-media content to the set-top box. Thereafter, in a fifth step, the controller in the set-top box reports the events regarding the selection of the second additional multi-media content via the web server to the application server. The application server stores this information and may use this for future keyword selections for new user requests that require first additional content. It will be appreciated that the invention also extends to computer programs, particularly computer programs on or in a carrier, adapted for putting the invention into practice. The program may be in the form of source code, object code, a code intermediate source and object code such as partially compiled form, or in any other form suitable for use in the implementation of the method according to the invention. The carrier may be any entity or device capable of carrying the program. For example, the carrier may include a storage medium, such as a ROM, for example a CD ROM or a semiconductor ROM, or a magnetic recording medium, for example a floppy disc or hard disk. Further the carrier may be a transmissible carrier such as an electrical or optical signal, which may be conveyed via electrical or optical cable or by radio or other means. When the program is embodied in such a signal, the carrier may be constituted by such cable or other device or means. Alternatively, the carrier may be an integrated circuit in which the program is embedded, the integrated circuit being adapted for performing, or for use in the performance of, the relevant method.
