Description

Procedure and system for recognition of IP television users.

Field of the Invention

The present invention belongs to the field of television over IP, and more specifically, to the recognition of IP television users.

Background of the invention

There are currently television channels (TV) over IP that provide television programs to users endings using bidirectional broadband IP connections. These TV channels work in two ways: for broadcast (in English, "broadcast") of programs, use IP technologies multipoint point or IP multicast (in English "IP multicast", according to the different RFCs defined by the IETF body), while for video on demand (in English, "video on demand", VoD), use point-to-point connections between the servers that create the audio and video stream (in English "streaming" servers and the television receiver, using IP protocols such as RTSP (in English, "Real Time Streaming Protocol ").

Although TV over IP technology allows know what program is being watched on each TV receiver (on TV over IP, unlike traditional cable TV, terrestrial or by satellite, there is no mass broadcast of channels to the receiver, but only those users receive are seeing or those more interesting for users, what implies that the transmitter of the TV channels must know which channels send to each receiver - for that it serves, among other things, the IP channel return-), so far they have not been able to get information on how many and which specific users are watching Each program at every moment. This information can be very interesting to, for example, provide services customized or adapted to the real audience in each home. Examples of these personalized services may be to provide personalized ads for each specific or joint viewer of specific viewers; facilitate the acquisition of certain content by payment via mobile, without the user have to give your bank account number to the channel television; provide custom channels to preferences of each viewer or have actual audience measures and snapshots, as well as by population segments, etc.

The international patent application WO2004 / 036893 describes a system that integrates television interactive and wireless technologies, using profiles user to customize the information provided to each viewer. However, this system presents a series of inconveniences, derived from the fact that any user can create a new profile, which results in a lack of security both in regards to who accesses the contents downloaded, as in the vulnerability and possibility of manipulation of the information collected in the user profile. In addition, since WO2004 / 036893 does not indicate how it is identified each user who watches television, it follows that, or well there is a static television-user association, or the user has to explicitly identify himself against television, which is a tedious process, both in what regards identification as prior registration. In both cases the privacy of the subscriber is compromised when used static customer identities. Moreover, when there are several users watching television at the same time through the same receiver the system described in WO2004 / 036893 is unable to filter contained in these circumstances or to automatically control the presence or absence of viewers.

Summary of the Invention

The present invention is intended to resolve the problems mentioned above through a procedure and system for the recognition of television users about IP.

In one of the aspects of the present invention, a procedure for the recognition of users of IP television comprising the following stages: set a short-range radio link between at least one mobile terminal and a decoder of a television receiver; set a point-to-point connection between the decoder and at least one server of a television content provider; characterized by the following stages: authenticate through a network wireless data to the subscriber corresponding to each of the mobile terminals, obtaining data from an identity provider relating to the subscriber of each mobile terminal; provide from each mobile terminal to the decoder at least one of said data relative to the subscriber; supply to said server through that connection that at least one data relative to the subscriber corresponding to each mobile terminal; locate, from at least one data relative to the subscriber, the profile of each subscriber.

Preferably, the data relating to the subscriber,  obtained from an identity provider, comprise at least one first identifier of each subscriber, more preferably a alphanumeric identifier of each subscriber. That first identifier can be a temporary identifier.

Preferably, in case at the stage of authentication, the identity provider does not own any data Unique identifier of the subscriber of a mobile terminal, the data relating to the subscriber of the mobile terminal comprise at least one data generic identification, and the location stage, from that at least one data relative to the subscriber, of the profile of said subscriber, provides a generic subscriber profile associated with that generic identifying data.

Preferably, the step of locating, from of said at least one data relative to the subscriber, the profile of said subscriber comprises: finding an access service interface to profiles and request from said services interface the profile of the subscriber from whose terminal said at least one has been provided fact; and return from the access services interface to profiles to the television content provider server, said subscriber profile. The stage of requesting said interface from services the subscriber's profile preferably comprises request a second from the service interface Identifier of the subscriber to the identity provider, from said data relating to the subscriber; provide to the interface of profile access services by the provider of identity, said second subscriber identifier; request to a data storage means the profile of the subscriber to from said second subscriber identifier; provide to the profile access services interface said profile of the subscriber. Said second subscriber identifier provided by The identity provider may be the subscriber's MSISDN.

Optionally, the stage of supplying the server through the connection of at least one of said data relative to the subscriber also includes providing information Decoder's own.

The process further comprises a stage of establish a connection, preferably IP, down for the data flow download between the provider's server TV contents and decoder. This connection descending can be point to point or point to multipoint.

When this downlink is point to point, the decoder's own information comprises a IP address of the decoder while when said connection descending point to multipoint, the information of the decoder comprises a multipoint IP address of the group or multicast groups of which the decoder is part of that instant.

If the downlink is point to point, information can be inserted into the downward data stream customized to the user's specific profile, preferably a ad.

If the downlink is multipoint point, the provider's server television content can check if this connection carries information adapted to the profile inserted in the data stream concrete of the subscriber or subscribers whose respective terminals phones are connected to the decoder. If it has been inserted in the  data flow information that does not correspond to the profile of the minus one of the subscribers whose respective mobile terminals are connected to the decoder, the server can create a new multicast group adapted to subscriber profiles and request to the decoder that connects to the new group. Alternatively, the server can ask the decoder to connect to another multicast group already existing. Alternatively, the server can create a point-to-point connection with the decoder whose connected subscribers have profiles that do not correspond to the flow data point-multipoint connection.

If the downlink is point to point, the TV content provider server can check if there is a multicast group whose data flow content is correspond to the profile of the subscriber (s) connected to the decoder and if so, the server can change the downlink (20) to that other existing multicast group, informing the decoder accordingly.

In the event that the radio link is broken from short range between the at least one mobile terminal and the television receiver decoder, the decoder notifies immediately to the content provider server of television of said rupture.

Alternatively, if the radio link is broken from  short range between the at least one mobile terminal and the television receiver decoder, the decoder stores the data related to the subscriber of the disconnected mobile terminal and what considered connected for a certain time, after which the decoder notifies the disconnection of the mobile terminal to TV content provider server.

Optionally, the method comprises the stage of generate by the service interface a record that includes the exchange of information between the interface of services and TV content provider. From the information collected in said register can be charged at TV content provider.

Optionally, the method further comprises the stage of generating by the content provider content vision statistics that each visualizes subscriber, as well as generate an electronic guide service for programming, specific for users who are connected to decoder

Another aspect of the present invention relates to to a system for the recognition of television users over IP, comprising: means for establishing a radio link of short range between at least one mobile terminal and a decoder of a television receiver; means to establish a connection point to point between the decoder and at least one server of a television content provider; characterized by next steps: means to authenticate through a network wireless data to the subscriber of each of said at least one mobile terminal, obtaining data from an identity provider relating to the subscriber of each mobile terminal; means for provide from the at least one mobile terminal to the decoder at least one of said data relating to the subscriber; means for supplying said server through said connection said to less one relative data to the subscriber; means to locate, from of said at least one data relative to the subscriber, the profile of each subscriber.

Brief description of the figures

In order to help a better understanding of the features of the invention according to an example preferred practical implementation of the same and to complement This description is accompanied as an integral part of it a game of drawings, whose character is illustrative and not limiting. In these drawings:

Figure 1 shows a scheme of the system and method for the recognition of television users over IP according to the present invention.

Preferred Embodiment of the Invention

Throughout this specification, the term "understand" and its derivatives should not be construed in a exclusionary or limiting sense, that is, it should not be interpreted in the sense of excluding the possibility that the element or concept to which it refers include additional elements or stages.

In addition, in the context of the present invention The following definition must be taken into account:

Mobile terminal: Telephone, PDA, portable equipment or similar capable of establishing connections through networks Wireless or cellular.

Figure 1 shows an example of a possible realization of the system and procedure for the recognition of IP television users. Figure 1 includes the following elements:

A personal communication device or mobile terminal 1, such as a mobile phone, a PDA, a laptop, etc .; this mobile terminal 1 is capable of connect to a wireless data network 6, such as DECT, GSM, GPRS, UMTS, WLAN, Wimax, etc. In addition, mobile terminal 1 has Short range radio communication capability, such as Bluetooth, infrared, or any other form of communication conventional short range radio. Although Figure 1 shows a single mobile terminal 1, there may be several mobile terminals 1 connected to the wireless data network 6 and able to establish also short range radio links.

A decoder 2 (in English "set top box ") equipped with the same radio communication capability of short range than the mobile terminal (s) 1, that is, Bluetooth, infrared, or any other form of communication conventional short range radio. Also, this decoder 2 it also includes connection via IP network (represented in the Figure 1 through reference 9) (for example, internet) towards a television content provider (TV), which is described to continuation. The IP connection can be, for example, of the DSL type (in English, "Digital Subscriber Line"), but this type of connection should not be considered limiting, but merely illustrative The decoder 2 is connected to a TV receiver 3. The decoder 2 can be, for example, a "Home Media Center ", that is, a personal computer with capabilities sophisticated multimedia, but this example should be considered Illustrative and not limiting.

An interactive TV content provider 4 in real time, capable of broadcasting over an IP network (for example, Internet) towards the decoder 2. The contents provided by provider 4 through a content server 10 can be sent to decoder 2 with both connections point to point (in English "unicast") as point to point connections multipoint (in English "multicast").

When they are point to point, the contents are specifically address the subscriber's decoder 2; for it, content provider 4 can use flow techniques constant (in English "streaming") along with such protocols as RTP (in English, "Real-time Transport Protocol ") for audio and video transmission, RTSP (in English, "Real Time Streaming Protocol"), for the management of session from decoder 2, and / or any other technique and conventional protocols used for applications of this kind.

When they are point-multipoint, the contents are directed to several decoders simultaneously, it is say, to multicast IP addresses. The multicast addresses are addresses, in this case IP addresses, which correspond to groups of subscribers. When a subscriber becomes part of a group multicast, you can start receiving audio and video packages through of conventional protocols used for this purpose, such as RTP, as long as the IP packets on which the audio travels and video have a destination IP address corresponding to that of the multicast group A user can join or separate from a group multicast through protocols like IGMP (in English, "Internet Group Management Protocol ").

An identity provider 5 capable of authenticating to a subscriber or subscribers. This authentication can be both transparent to the subscriber (that is, in which the subscriber does not perform any conscious action on your part to be authenticated) as explicit (that is, in which the subscriber consciously consents to be authenticated, for example entering a login and password (in English, "password"), or simply by pressing a key that says "authenticate"). An example of transparent authentication is using mechanisms such as 3GPP GAA (Generic Authentication Architecture). The identity provider 5 is capable in addition to assign each subscriber, during authentication, at least one data, preferably a first identifier, which can be Temporary or permanent. In a preferred embodiment, this identifier is temporary, because this way you can guarantee certain privacy of the subscriber in front of the decoder and the provider of TV contents. Identity provider 5 communicates with the subscriber (that is, with mobile terminal 1 thereof) through a wireless data access network 6, such as GSM, GPRS, UMTS, WLAN, Wimax, etc.

A service interface 7 (for example, a interface based on web services over IP) through which the 4 interactive TV content provider is able to check the profile of the subscriber from a first identifier of the subscriber, which in turn is provided by the decoder 2. More The following explains how the content provider 4 of TV this subscriber identifier.

A database of 8 profiles, which contains subscriber profiles These profiles can comprise data demographic, usage history, preferences, or any other subscriber information

The procedure for the recognition of television users over IP.

Each mobile terminal 1 and the provider of identity 5 communicate with each other through a wireless network of data 6. As stated earlier, this wireless network 6 data can be GSM, GPRS, UMTS or a local area network wireless (for example, WLAN, Bluetooth, Wimax, etc.). Through the connection to this wireless data network 6, the provider of Identity 5 authenticates the subscriber and user of a mobile terminal 1. This authentication stage is represented in Figure 1 by reference 11. Authentication 11 can be performed, by example, when the subscriber turns on mobile terminal 1, when the subscriber starts a specific application from terminal 1, when request identity provider 5, etc. Authentication 11 it can be transparent, for example using mechanisms such as 3GPP GAA, or explicit by the subscriber.

If this authentication 11 is successful, that is, if the identity provider 5 has any identifying data exclusive to the subscriber of mobile terminal 1, its result is the reception by the mobile terminal 1 of some data on the Identity of the subscriber, coming from the identity provider 5. These data on the identity of the subscriber include at least:

-

a alphanumeric subscriber identifier, or first identifier, that It can be temporary or permanent. The identifier is preferably temporary, in which case the authentication process 11 is repeated periodically or upon request of mobile terminal 1 or from identity provider 5;

Optionally, the identity data of the Subscribers may also include:

-

a information about identity provider 5 that you have authenticated to subscriber;

-

a address of the service interface 7 through which you can subsequently obtain the subscriber's profile or, alternatively, a pointer to a services directory, which you can ask by the address of the service interface 7 from which you can Obtain the subscriber's profile.

Also optionally, data on the Identity of the subscriber may include other information, as the operator of the wireless network to which the terminal (eg Vodafone), the technology used in the network wireless (for example, UMTS), the authentication method used, the day and time of the same, some digital signature of the provider of identity 5 that guarantees the authenticity of the information of authentication, etc.

Alternatively, if authentication 11 is not successful, that is, if authentication 11 does not provide at least a first identifier that uniquely identifies the subscriber, the Identity provider 5 can provide identifying information generic, which does not correspond to any specific subscriber (for example, an alphanumeric identifier as `` anonymous ''). Be provides this same generic identifying data for all subscribers whose authentication 11 has not provided a unique identifier of the subscriber. In this case, although the The process of the present invention is not able to locate the profile of the specific subscriber because he does not have a unique subscriber identifier, if it is capable of, for example, count the actual number of subscribers, even if they don't know their concrete profiles Thanks to this generic identification data, the subscribers with unknown profile can receive information, by example, generic advertising, since its presence has been perceived. What's more, this generic identifying data can associate with a generic user profile, preferably related to a frequent user profile, such as associated with men of a certain age range.

The procedure also includes a stage of establishment of a short-range radio link between al minus a mobile terminal 1 and the decoder 2 of the receiver of television 3. This stage of establishment is illustrated in the figure 1 with reference 12. As stated above, this link Short range radio 12 can be Bluetooth, infrared, or Any other form of short-range radio communication conventional.

To establish this link 12, both the mobile terminal 1 as decoder 2 must have active the respective short range radio functionality. The link between the mobile terminal 1 and decoder 2 can be started both in the mobile terminal 1 as in decoder 2. Optionally it can be carried out a previous stage of explicit acceptance of such connections in mobile terminal 1, both initiated by any element with the same short range radio functionality as initiated from specific decoders, so that the lifting of the radio link between decoder and terminal be transparent to the user. Through said link 12, the decoder 2 is identified as "decoder authorized by the user ". Optionally, this identification can go accompanied by an authentication process from decoder 2 towards mobile terminal 1, to prevent other devices from supplanting the identity of the decoder 2. This authentication may require checking by mobile terminal 1 (local or remote, that is, by contacting mobile terminal 1 with some decoder authentication server through it wireless network through which you have previously authenticated with the identity provider 5) of the identification data supplied by decoder 2, although the check is not essential. Via link 12 the mobile terminal 1 supply decoder 2 with at least one (all or part) of the data on the identity of the subscriber, received from the provider of identity 5 in stage 11. The at least one identity data of the subscriber comprises the alphanumeric identifier of the subscriber. In case of unsuccessful authentication, it is supplied to the decoder 2 the generic identification data of the subscriber.

The order of stages 11 and 12 can be alternated,  because the short-range radio link 12 can be established in first place and, when warning the mobile terminal 1 that does not have a valid subscriber identifier to use with decoder 2, the terminal 1 can start authentication stage 11 to obtain said identifier. This subscriber authentication 11 can be transparent to the subscriber or require explicit consent by the subscriber. Optionally in that scenario, the decoder 2 can provide mobile terminal 1 with a list of identity providers preferred by the content provider of television 4.

The procedure also includes a stage of connection between decoder 2 and one or more servers 10 of the 4 interactive TV content provider over the IP network 9. A single server 10 is illustrated in Figure 1. this connection 13, which is point to point and which in figure 1 has represented by reference 13, decoder 2 le supplies the server or servers 10 with the information received from mobile terminal 1, that is, the at least one (all or part) of the data on the identity of the subscriber or, alternatively, the data generic identification. The at least one data on the identity of the subscriber comprises the alphanumeric identifier of the subscriber that the decoder 2 obtained by mobile terminal 1. Additionally, decoder 2 also supplies information of decoder 2, such as a code Identification

The downlink between the provider of contents 4, through a server 10, with decoder 2, to provide the user with audio and video content can be both point to point and point to multipoint. This connection is represented in figure 1 by reference 20. In the case of that the contents coming from provider 4 are sent to 2 point-to-point decoder, this information from the decoder 2 comprises the IP address of the decoder. At If the contents from the provider 4 are sent to the decoder 2 point-multipoint (IP multipoint, in English, "IP multicast"), that is, if the Decoder 2 belongs to a multipoint group or multicast group, that decoder 2's own information comprises an address Multicast IP of the group (or groups) of which (or of which) the decoder 2 is part.

Then the content provider 4 of TV locates, based on said at least one identity data of the subscriber of the mobile terminal 1, the profile of said subscriber (which alternatively it can be a generic subscriber profile to which You have referred to above in the case that at the stage of authentication the identity provider 5 does not possess any data exclusive identification of the subscriber). This location stage It can be divided into several stages:

On the one hand, the server (s) 10 of the content provider 4 look for a service interface 7 of access to profiles using the data or data on the identity of the subscriber provided by decoder 2 and once found, they request to said service interface 7 the profile of the subscriber whose terminal 1 is within the radio range of the decoder 2. Optionally, this request may include content provider authentication information 4 for avoid unwanted requests in service interface 7 of profile access Also optionally, before looking for this profile access service interface 7, the servers 10 of the content provider 4 check in their databases the information of decoder 2 to verify that it is valid (to, for example, ensure that only certain Decoders authorized by the content provider 4 access the information sent by the servers 10 of said 4) supplier.

This service interface 7 access to profiles can be known by default by the provider of 4 television content or it can be part of the information supplied to mobile terminal 1 by identity provider 5. Also, said information supplied to mobile terminal 1 by the identity provider 5 can include the address of a directory of services to look for, for the terminal subscriber mobile 1, the address of the service interface 7 that gives access to the profile of said subscriber.

Subsequently, said service interface 7 returns to server 10 of television content provider 4  said subscriber profile or a generic profile if the subscriber does not uniquely identified in the authentication stage.

This stage of requesting and receiving the profile of a subscriber can also be subdivided into several sub-stages:

On the one hand, the service interface 7 ask the identity provider 5 for a second identifier of the subscriber. This stage is represented in Figure 1 by the reference 15. To do this, the service interface 7 provides the Identity provider 5 the at least one data related to the subscriber (obtained in the authentication stage) that in turn the decoder 2 has sent to content provider 4.

In case of successful authentication, that is, resulted in a unique subscriber identifier, the at least one data on the identity of the subscriber comprises the alphanumeric subscriber identifier. From this data of subscriber (user of terminal 1), identity provider 5 provides the service interface 7 with a second identifier of the subscriber that can be used as an index for the search in the profile database 8. This stage is represented in the figure 1 by reference 16.

Alternatively, if the authentication has not been  successful in the sense that it has resulted in data generic identifier, identity provider 5 provides the service interface 7 a second generic identifier, associated with the previous generic identification data, which can be used as an index for searching the profile database 8.

In both cases, the identity provider 5 converts the relative data to the subscriber (for example, a first identifier) in a second identifier usable as an index for searches in the profile database 8. An example does not Limiting of said usable identifier is the subscriber's MSISDN. In case the authentication has not been successful, an example non-limiting of said usable identifier is an MSISDN with the following characters: 600000000. Optionally, this request can subsequently trigger an authentication request of the subscriber's terminal 1 as described in step 11, with in order to renew the subscriber data or data mentioned in that stage.

Identity provider 5 provides (represented in figure 1 by reference 16) to the profile access service interface 7 said second subscriber identifier or, alternatively, second generic identifier

With this new subscriber identifier (or alternatively second generic identifier), the interface of services 7 requests the data or base storage media of data 8 the profile of the subscriber corresponding to said identifier This stage is represented in Figure 1 by the reference 17. The subscriber's profile may be made up of data that include subscriber demographics, such as age, sex, marital status, postal address, etc., preference data of the subscriber, data of services subscribed by the subscriber, a permanent subscriber identifier that can be correlated with the internal customer databases of the content provider TV, etc.

Finally, the profile database 8 provides the profile access service interface 7 with profile of the requested subscriber (or where appropriate, a generic profile). This stage is represented in Figure 1 by reference 18. The profile access services interface 7 returns the profile in question to the servers 10 of the content provider 4 of TV. This stage is represented in Figure 1 by the reference 19. Optionally said profile can be signed digitally through service interface 7 to ensure the authenticity and integrity of it.

The service interface 7 can insert in its  records the exchange of information made between the server 10 and TV content provider 4, with a view to example, to charge you for such requests.

With this information, the content provider 4 You can use this profile for various applications. By for example, the servers 10 of the TV content provider 4 they can:

-

Post the customer and his profile to the realization of vision statistics of the contents of the TV content provider 4; such statistics can be used later, for example, to give promotions to each subscriber in function of the time and programs displayed by the subscriber (this that is, to create a point program associated with the vision of channels of TV, translatable points by the subscriber in gifts, promotions, etc.). In this way customers are encouraged to have their terminal mobile 1 connected to decoder 2 when they are watching the television through the receiver 3.

-

If the 20 downlink connection of the subscriber decoder 2 with Content provider 4 is point to point, can be inserted into the data flow (video and audio) descending (towards the subscriber decoder 2) personalized information, as per example a personalized ad to the specific profile of the client. This ad can be extracted from the ad inventory of the content provider 4. Preferably, this inventory is segmented by audience to which each ad is directed. Thus, the subscriber sees in the video received on his receiver 3 TV ads adapted to your profile. Provider 4 knows which decoder 2 send the data stream for having previously received a identifier of the same.

-

If the 20 downlink connection of the subscriber decoder 2 with Content provider 4 is point-multipoint, Content provider servers 4 can check if the IP multicast group to which decoder 2 is connected is including, along with the content being disseminated, advertising adapted to the profile of the subscriber who owns the terminal. If so, nothing is changed. If, on the contrary, it is not, you can ask server 10 to change your connection multipoint point by another multipoint (multicast) to a group in which it is spreading, along with the same content, advertising adapted to the subscriber's profile owner of terminal 1, or if said group does not exist, for a point to point (unicast with streaming) between the decoder 2 and TV content provider 4. In the case in that the servers 10 of the content provider 4 detect that there are several subscribers of the same profile (and therefore, susceptible to receive the same advertising) connected point to point (unicast) with content servers, it can be generated, if it is possible (for example, if there are no limitations on the number of multicast IP addresses available), a new multicast group, assign a free multicast IP address and insert advertising customized in the content in question, sending the flow of Video and audio to the specified IP address. Also, the Servers 10 of TV content provider 4 should request the corresponding decoders 2 changing their connections point-to-point (unicast) to a new point-to-multipoint connection (multicast) with that multicast IP address that just create.

-

Send to decoder 2, if this allows the user to navigate through internet, web page addresses (in English "urls") associated with the information, for example advertising, that is being sending, either by multicast or by unicast. That way, the subscriber can access more information related to Ads you see and even place orders using the decoder 2. Those addresses can correspond directly to the pages advertisers website or pages of the provider’s site TV content 4, so that content provider 4 You can be aware of what requests users make, with in order to be able to charge those advertising impacts to Advertisers The addresses in question can be embedded the identifiers of the clients connected to decoder 2, known by the content provider 4.

In short, server 10 of the provider of television contents 4 can send to decoder 2 personalized information for the subscriber.

The control of the presence and proximity of subscriber to decoder 2 is performed with radio communication of short range 12. When it breaks, decoder 2 must assume that the subscriber is not watching TV and notify conveniently to TV content provider 4 to take the appropriate measures (for example, interrupt the discharge of personalized information to said subscriber). However, optionally the decoder 2 can have a means of storage (not illustrated in figure 1) where to store the identities of subscribers whose short radio communication scope 12 just got lost. Thus, decoder 2 only notifies to TV content provider 4 the breakdown of a communication short range radius 12 if the duration of said disconnection exceeds a certain time threshold. This avoids notifying  as disconnections what are simply escaped from the subscriber to the kitchen or the service, for example.

In the event that these radio communications from short range exceed this time threshold (this threshold being time one parameter that can be varied), decoder 2 must inform server 10 of television content provider 4 for it to act accordingly. The possible actions of 4 content provider are, I entered others:

-

If the 20 downlink connection of the subscriber decoder 2 with Content provider 4 is point to point, interrupt the insertion of personalized information to the subscriber's profile disconnected in the downstream data flow.

-

If the 20 downlink connection of the subscriber decoder 2 with the content provider 4 is point to point, you can also ask decoder 2 to change its connection point-point (unicast with streaming) on the other multipoint point-to-group connection multicast in which it is being included, along with the content that it is spreading, advertising adapted to the profiles of the rest of subscribers whose mobile terminals 1 are connected to the decoder 2.

-

If the 20 downlink connection of the subscriber decoder 2 with content provider 4 is point-multipoint and the multicast IP group to which decoder 2 is connected is including, along with the content being disseminated, advertising adapted to the profile of the terminal owner subscriber mobile 1 that has just disconnected, can be requested from the server 10 change your point-multipoint connection (multicast) by a point-point (unicast with streaming), so that the decoder 2 stops receiving said advertising adapted to the profile of the subscriber who owns the mobile terminal 1.

-

If the 20 downlink connection of the subscriber decoder 2 with content provider 4 is point-multipoint and the multicast IP group to which decoder 2 is connected is including, along with the content being disseminated, advertising adapted to the profile of the terminal owner subscriber mobile 1 that has just disconnected, can be requested from decoder 2 that connects to another multicast group in which is including, along with the content that is being disseminated, advertising adapted to the profiles of the rest of the subscribers whose mobile terminals 1 are connected to the decoder 2.

Since several subscribers may be watching the same TV receiver 3, its mobile terminals 1 can all be connected to decoder 2. In that case, the servers of the TV content provider 4 can make a decision on what type of information (eg advertising) send to decoder 2 in question, depending on the inventory of information (publicity) that they have and the profiles of the subscribers concrete whose terminals 1 are connected to decoder 2. Therefore, they must have a temporary database that associates each identifier of each decoder 2 with the identifiers of subscribers connected to it or with their profiles. Of the same mode, said database must associate each decoder 2 with the TV channel that is being watched on TV receiver 3 corresponding, as well as the type of connection (unicast or multicast) existing between each decoder 2 and the servers 10 of the TV content provider 4.

In the event that the content provider of TV is offering an Electronic Programming Guide service (in English EPG or "Electronic Programming Guide"), said service must be adapted to each decoder according to the user profiles connected to it through its mobile terminal, so that the channel change in the decoder allow the decoder to connect (unicastly or multicast) immediately to the desired TV channel with the custom advertising.

In view of this description and game of figures, the person skilled in the art will understand that the invention has been described according to some preferred embodiments of the same, but that multiple variations can be introduced in said preferred embodiments, without leaving the object of the invention as claimed.
