Definitions
- the present invention relates to TV systems and mobile 5 communication systems, and in particular to a method for handling services in a system as described in the preamble of claim 1.
- the present invention further relates to a system for handling services as described in the preamble of claim 13.
- the present invention also relates to a server arrangement for use in a system as described in the preamble of claim 1 .
- L5 systems with a conditional access e.g. pay-TV systems
- a user may obtain various services on request, e.g. view a pay-per-view movie or get access to a TV channel.
- a pay-TV system the user is equipped with a decoder that is connected between a TV tap and a TV set at the user's 0 premises.
- a main part in the system transmits encoded and uncoded signals that the decoder receives via the TV tap.
- the encoded and uncoded signals may represent encoded and uncoded TV programmes/channels, and the decoder may then decode parts or all of the encoded signals depending on access rights of 5 the user, and thereby access rights of the decoder, i.e. which channels/programmes the user pays to get access to.
- Recent systems are often digital, i.e. the system broadcasts digital signals that are decoded by a digital decoder.
- the advantage with digital systems vis-a-vis analogue systems is that a considerably larger quantity of data may be transmitted, and by that a considerably larger number of TV channels.
- the larger capacity in the digital systems also allows space for other services, for example interactive services such as games and surfing the Internet, where a user via a return channel in the system may influence and interact with what is shown on the TV set.
- DE 4424380A1 describes a system where a user may order e.g. pay-per-view services via his mobile telephone.
- the user orders the service by giving a suitable code via the mobile telephone to a server.
- the server transmits decoding information to a decoder at the user's premises and the desired service is obtained.
- the user is identified via the mobile network and is debited e.g. once a month.
- Other data may as well be transmitted via the mobile telephone, e.g. the user may play an interactive game where the commands are sent via the mobile telephone.
- the object of the system is to facilitate ordering of services for a user.
- the user may make the order via the mobile telephone instead.
- DE 4424380 Al it is presumed that the user is associated with a certain decoder in the server and that the server in that way knows which decoder the decoding information shall be sent to when a user gives an order.
- a pay-TV system is described in the Swedish patent SE 509 582 C2 , which describes a system where a user as in the above described system may order for example pay-per- view services via his mobile telephone.
- the user orders the service by giving a suitable code via the mobile telephone to a server.
- the user is identified via the mobile network.
- the system is aimed at using a mobile communication network as a return channel and particularly the problem of increasing capacity for the interactive return channel so that other types of services may be ordered by a mobile user.
- a user is associated with a certain decoder in the system.
- pay-TV systems are designed with an architecture that maintains a 1:1 relationship between a user and a decoder, i.e. the user is associated with a certain decoder in the system and any service orders made by him is automatically delivered to the decoder that is associated with the user.
- EP 1 030 272 A2 discloses a system for handling and performing electronic payments with electronic assets such as cash cards in inter alia a pay-TV system where the 1 : 1 relationship between a user and a service supplier is broken.
- the system consists of a stationary terminal, e.g. a decoder or a PC, a mobile terminal and a server communicating via a communication network. Ordered services may be a pay-per-view programme.
- the decoder may be at home, at a friend's premises or in a hotel.
- the decoder has a return channel to the system and a link to the mobile terminal via IR or radio.
- An order to an optional decoder may be made from the mobile terminal.
- EP 1 030 272 A2 In EP 1 030 272 A2, however, special decoders and mobile terminals constituting part of the debiting system are required. It is further required that the user is registered in the debiting system with username and password. A problem with the current systems is that it is not possible to achieve flexibility for the user via existent infrastructure.
- the object with the present invention is to provide a method for handling services in a system including a TV system and a mobile communication system that solves the above problem.
- Another object with the present invention is to provide a system for handling services, which system admits a solution of the above problem. This object is achieved with the system according to the characterising portion of claim 13.
- a further object with the present invention is to provide a server arrangement, for use in a system for handling services, as set forth in the characterising portion of claim 14.
- An advantage with the present invention is that at a service request regarding a service to be delivered to an arbitrary stationary terminal in the TV system, initiated from a mobile terminal in the mobile communication system, which service request includes the identity of the stationary terminal and is sent via the mobile communication system to the server arrangement, the means for identifying a mobile terminal user in the mobile communication system is used to identify a system user.
- Another advantage with the present invention is that the 1:1 relationship between a user and a service provider is broken and the user is given the possibility to use his subscription more freely by creating a temporary connection between the user's mobile telephone and an optional decoder, while at the same time existing infrastructure in the system is maintained.
- Another advantage with the present invention is that a user may be at many different geographical positions, as in a hotel room or at somebody else's premises and still get access to various pay-TV channels, pay-per-view programmes, games, voting information, betting information and shopping information via his subscription, irrespective of who the owner of the decoder is.
- Another advantage with the present invention is that in connection with an order of a service or delivery of a service, a debit data post that may be used in an arbitrary debiting system is established, e.g. by any of the means for debiting in the mobile communication system or a cash card system.
- Another advantage with the present invention is that a plurality of orders from a user may be stored in a data post together with the identity of the user in order to be debited at certain time intervals, e.g. each month or at a certain achieved amount.
- Another advantage with the present invention is that it opens a parallel path to create authorisations, particularly temporary ones, in an existing pay-TV system.
- Another advantage with the present invention is that it uses existing infrastructure and is applicable to all kinds of mobile communication systems and TV systems.
- Another advantage with an embodiment of the invention is that it makes verification of that the mobile terminal and/or someone with a connection to the mobile terminal is present at the stationary terminal possible.
- Fig. 1 shows a conventional pay-TV system for use in accordance with the present invention.
- Fig. 2 shows a system in accordance with a preferred embodiment of the present invention.
- Fig. 3 shows an alternative embodiment of the access part in the system shown in fig. 2.
- Fig. 4 shows a signal diagram of the signalling at the establishment of a connection between a mobile terminal and a stationary terminal in accordance with a preferred embodiment of the present invention.
- service in the description is meant e.g. access to TV channels, pay-per-view programmes, games, shopping information, betting information, voting information etc.
- set-top-box STB
- STB set-top-box
- Fig. 1 shows a conventional pay-TV system 1 that may be used in a preferred embodiment of the invention.
- the system comprises a TV set 2 and a set-top-box (STB) 3 connected to the TV set.
- the set-top-box and the TV set may be located e.g. at the users home, at an acquaintance's premises or at a hotel.
- the STB and/or the TV set is connected to a distribution network 4, which may consist of a terrestrial TV distribution network, a satellite TV distribution network or a cable-TV network.
- the distribution network 4 often is a digital network utilising standards developed by DVB (Digital Video Broadcasting) in the data transmission.
- DVB Digital Video Broadcasting
- a multiplexer that combines the information 6, 7, 8, 9, 10 that is to be transmitted via the distribution network 4, and that effects that the information is transmitted is connected to the distribution network.
- the information 6, 7, 8, 9, 10 constitutes partly of the TV channels and TV programmes 6 that are to be transmitted via the distribution network, partly by radio 7, partly by e.g. games and other information such as betting information 8, and partly by control information 9, 10, which will be described more in detail below.
- Each supplier of pay-TV services has his own pay-TV system and in order to allow a plurality of pay-TV systems to coexist in the same distribution network a standard called SimulCrypt has been developed to allow control information from several service suppliers to be sent over the same distribution network.
- the control information 9 consists of control word messages, ECM messages (Entitlement Control Message) , that are generated in an ECM message engine 11.
- ECM messages comprise keys to decrypt various transmissions (e.g. TV channels) .
- a security module 12 in the STB 3 reads the ECM messages together with
- the safety module 12 may constitute an integrated part of the STB 3 or consist of a separate module that is to be put into the STB 3.
- the user's identity is stored on an intelligent card that is connected to the safety module 12 via a card reader.
- the control information 10 consists of messages for entitlement, Entitlement Management Messages (EMM messages) that is used to transfer rights to the STB.
- EMM messages are generated by an EMM engine 13 and comprise information about the user's identity and which services the receiver shall decrypt.
- the safety module 12 in the STB 3 reads the EMM messages to get knowledge of what the STB 3 shall decrypt and make available to the user, and then uses the ECM messages as decryption keys to be able to decrypt the selected services.
- the SMS 15 is a system that handles subscriber information and sends requests for activation of services to the SAS 14, which translates information from the SMS 15 to EMM messages and makes sure that the security module 12 at the user's premises receives correct authorisation so that correct service may be decoded.
- the SMS is more or less unique for each service supplier and may be arranged such that there is an operator keying in which users that shall have which services.
- An object with the present invention is to break apart the above mentioned relationship by allowing a user to more freely use his subscription by creating a temporary connection between the user's mobile telephone and an optional STB in the system, and at the same time maintain the existent infrastructure in the system. For example, a user shall be able to visit another STB holder and himself be able to pay for the movie of the night via pay-per-view. Alternatively, the user may use his subscription during a hotel stay and in the same way be able to watch an optional movie or a TV channel .
- fig. 2 shows a system according to a preferred embodiment of the invention. Details that are similar to those in fig 1 maintain the same reference numerals and will not be described more in detail .
- the system in fig 2 comprises decoders 3, 22 with safety modules 12, 23 and TV sets 2, 24 connected to the decoders.
- the system further comprises a distribution network 4, a multiplexer 5, an ECM engine 11, an EMM engine 13 a SMS 15 and a SAS 20.
- the services that is to be available via the distribution network 4 e.g. various TV channels 25, 26 and other services such as games, betting information etc. 27, is connected to the multiplexer.
- a server arrangement 21, separate from the pay-TV system 1, is connected to the SAS.
- the server arrangement 21 has opening of a parallel path as a task in order to, aided by the SAS, create EMM messages that gives a temporary authorisation to a certain STB 3, 22 to show e.g. a TV channel independently of who owns the STB 3, 22.
- the server arrangement 21 further handles debiting of the service that the temporary authorisation has resulted in.
- a user 33, 34 wishes to order a service he/she contacts the server arrangement 21 via his/her mobile terminal 31, 32.
- the user is identified via the mobile communication system 30, which in the case of GSM is effected through that a user first identifies himself with a PIN code vis-a-vis his SIM (Subscriber Identity Module) card 35, 36 on activation of his mobile terminal, whereupon the SIM card 35, 36 is identified in the mobile communication system via the IMSI number (International Mobile Subscriber Identity) of the SIM card 35, 36.
- IMSI number International Mobile Subscriber Identity
- the server arrangement 21 When the user 33, 34 has established contact with the server arrangement 21, the user 33, 34 states a desired service and an identity of the STB the user wishes to get the service delievered to.
- the server arrangement 21 then sends information to the SAS 20 about the service concerned and which STB that is to get access to the service.
- the SAS 20 translates the information from the server arrangement 21 into EMM messages and makes sure that the security module 12 at the user's premises 33, 34 receives a correct authorisation so that the correct service may be decoded.
- the server arrangement In connection with the service order, or the delivery of the service, the server arrangement establishes a data post for debiting that is stored together with the users ID. The data post may then be used to debit the user via any optional debiting system, e.g.
- the debiting means in the mobile communication system or as debiting vis-a-vis a pre-payment account that a user may have with the operator of the server arrangement 21.
- Debiting may also be carried out by invoice or by debiting a credit card of the user.
- Several orders may be stored in one data post so that debiting may be carried out at certain time intervals or when the cost for the orders have reached a certain amount .
- the server arrangement 21 further takes care of that the payment is apportioned in a correct manner between the mobile operator, the service provider (e.g. the owner of the TV channel) , the owner of the server arrangement 21 and the owner of the pay-TV system.
- the contact between the mobile terminal 31, 32 and the server means 21 may be established in several ways. For example, the user may dial a certain number via the mobile telephone and then get menus read from which the user then on request may key in the STB identity and select a desired service.
- the server arrangement 21 One way to simplify the method vis-a-vis the server arrangement 21 is to provide the SIM card of the mobile telephone with applications that generate extra menus in the mobile telephone. The user may then use the extra menus to establish contact with the server arrangement 21 and to order services. In order to get a possibility to put the applications on the SIM card, e.g. the owner of the server arrangement 21 may act as a virtual mobile operator that issues its own SIM cards programmed with desired applications.
- fig. 3 Another example on how the connection may be established is shown in fig. 3.
- fig. 3 it is shown how a user's mobile terminal 41, provided with a WAP (Wireless Application
- a user that wishes to order a service enters an IP address via a WAP gateway that is administered by the owner of the server arrangement 21 and that is integrated in the server arrangement 21 or is in connection with it. Via the WAP page the user may then via menu choices order a desired service and on request input the identity of the decoder that the user wishes to get the service delivered to, whereupon the server arrangement 21 takes care of the delivery of the service according to the above.
- SMS Another way of establishing the connection is via SMS.
- the user sends a SMS to the server arrangement 21 with the STB identity and a code representing the service that the user wishes to order.
- connection between the mobile terminal and the STB may be established in the following manner, as will be described with reference to fig. 4.
- Fig. 4 shows a signalling diagram for signalling between the mobile terminal, the server arrangement 21 and the STB when a connection is established between the mobile terminal and the server arrangement 21.
- the server arrangement 21 When the user contacts the server arrangement 21 via his mobile terminal he (she) is identified via the mobile terminal according to the above (arrow 1) and receives a request for the ID number of the STB he is present at by the server arrangement 21 (arrow 2) .
- the user sends the ID of the STB (arrow 3) to the server arrangement 21, which responds by sending a control code to the STB (arrow 4) , which is shown to the user, and which the user sends back to the server arrangement 21 (arrow 5) via the mobile terminal in to show that he/she actually is present at that particular STB.
- connection is established (arrow 6) and the user is then inquired for the desired service according to the above (arrow 7) and requests the desired service (arrow 8) .
- the server arrangement may then respond with an acknowledgement (arrow 9) .
- a request for a PIN code to approve debiting of the service may be sent together with the acknowledgement (arrow 9'), whereupon the user responds by sending his PIN code (arrow 10') .
- the user may put the STB in a message receiving mode using the remote control of the STB in order to make message displaying possible, as shown with arrow 11 in fig 4.
- the user If the user has contacted the server arrangement 21 via SMS the user also sends the control code and the PIN code, if any, to the server arrangement 21 via SMS.
- the control code and the PIN code may be sent in the same SMS.
- the server arrangement 21 may be connected to a message generator 28, which is connected to the multiplexer 5, shown in fig. 2.
- the message generator 28 creates a message that is transmitted via the distribution network .
- the message is received by every STB that is connected to the distribution network 4, but is only displayed on the TV set that is connected to the particular STB the message is addressed to.
- the server arrangement may send various kinds of messages to STBs, e.g. the above mentioned control code.
- Another way for the server arrangement 21 to send messages to a STB is to send the messages via an application server 27 (shown in fig. 2) .
- the messages is received by a special software client in the STB for subsequent presentation on the TV set.
- STB identities for the user may either choose STB identity from a list where the STB identities are named or state the STB with a name or short number.
- the server arrangement does not have to constitute a separate unit in the system, but may also be integrated in the SAS or in the SMS.
- the exact localisation of the STB may depend on whether it is the same owner of both the server arrangement and the pay-TV system. Where this is the case it may be advantageous that the server arrangement is integrated with either the SAS or the SMS. In this case the interface between the TV system and its surroundings is considered to pass within the subject construction component, e.g. the server arrangement integrated with the SAS.
- the mobile communication network consists in the above example of a circuit switched GSM system.
- the communication may, however, of course as well be packet switched, and the mobile communication system may consist of an arbitrary mobile communication system, such as GSM, GPRS or UMTS.
- connection in the mobile communication system between the user' s assigned IP address and the user's IMSI/telephone number or equivalent is used to identify the user.
