Definitions

  • the present invention relates generally to a method, a system and a business model for performing sale of products.
  • the products may be new goods, secondary market goods, services, collectibles etc.
  • the present invention relates more particularly to implementing auctions with telecommunications media.
  • Most systems for processing the electronic sale of products are seller-driven, whereby the seller prices, packages, configures and offers the product for sale, and the buyer decides whether or not to accept the seller's offer. It is also prior known to arrange electronic auctions, wherein a seller and/or a buyer can make offers to sell/buy a determined product. When the offers to sell and buy meet, a transaction is recorded between the seller and the buyer. For example, the auction management system may process each received buying offer to determine whether one or more counterparts are willing to accept the offer. If a seller accepts a given purchase offer, and ultimately delivers goods complying with the buyer's offer, the buyer is bound on behalf of the accepting seller, to form a legally binding contract. A purchase offer thus is a binding offer containing one or more conditions.
  • the buyers may have, for example, a general-purpose account, such as a credit or debit account.
  • the buyer must therefore have an agreement with a bank and the auction service provider for the payment of purchases.
  • the delivery and quality of the products to be sold can be guaranteed by the dealer/authenticator, which can be part of the auction management system or another third party having knowledge of the subjecr goods.
  • the dealer/authenticator may also serve as the distribution point for the products.
  • a prior art system for implementing electronic sale is disclosed in patent application document WO 99/23595 [1].
  • FIG 1 illustrates a prior art purchase management system 100 for receiving and processing conditional purchase offers (CPOs) for collectibles from one or more buyers, such as buyers 110 and 120.
  • the CPO management system 100 processes each received CPO to determine whether one or more sellers, such as sellers 130 and 140, are willing to accept a given CPO. If a seller accepts a given CPO, and delivers goods complying with the buyer's CPO, the collectible CPO management system 100 binds the buyer 110 on behalf of the accepting seller 130, to form a legally binding contract.
  • CPOs conditional purchase offers
  • the goods are preferably forwarded to a dealer/authenticator, such as dealer/authenticator 150 or 160, for evaluation.
  • the dealer/authenticator 150 can be part of the collectible CPO management system 100 or another third party having knowledge of the subject goods.
  • the dealer/authenticator 150 preferably validates, authenticates and . optionally guarantees the goods, while also serving as the distribution point for the goods sold by the CPO management system 100.
  • validation establishes that the item actually exists. Authentication proves that the item is in the condition stated by the seller. The guarantee, if desired, insures that the buyer has not purchased a fake or counterfeit item.
  • the dealer/authenticator 150 can deliver the item to the buyer and authorize payment to the accepting seller.
  • the collectible CPO management system 100 allows a number of sellers to conditionally accept each CPO. In this manner, the collectible CPO management system 100 ensures that at least one of the accepting sellers will have the collectible item in the condition specified by the buyer.
  • each of the accepting seller(s) are prioritised into a hierarchy based on predetermined criteria. For example, sellers may be assigned a priority in the hierarchy based on the order in which their acceptances are received by the CPO management system 100. Alternatively, priority may be determined based on the geographical proximity of each accepting seller to the buyer. In addition, the priority may be based on the performance of each accepting seller for previous transactions.
  • a CPO is thus a binding offer containing one or more conditions submitted by a buyer for the purchase of goods, at a buyer-defined price.
  • the CPO may be guaranteed, for example, using a general-purpose account, such as a credit or debit account, maintained by an issuing bank, such as issuing bank 170 and 180.
  • the conditions specified in a CPO may also include, for example a description of the goods and a required quality.
  • the CPO management system 100 includes a central controller 190 for processing the information in a manner described above.
  • Each buyer and seller contacts the CPO management system 100, for example, by means of telephone line, in-person contact or through an agent, and provides the CPO management system 100 with the terms of their CPOs, or the list of available items the seller desires to sell, as appropriate.
  • Each buyer and seller may employ a general-purpose computer, for communicating with the collectible CPO management system 100.
  • the general-purpose computer of each buyer and seller is preferably comprised of a processing unit, a modem, memory means and any software required to communicate with the collectible CPO management system 100.
  • the communication between the auction management system and the user is carried out via a telephone line.
  • the user may have a computer with a modem, and the user makes a call to the auction service provider.
  • the user In order to get information on the products that are in sale and in order to make offers, the user needs to have continuous telephone connection to the auction management system. A continuous connection further causes high expenses to the user. It also takes a lot of time for the user to follow the auction, and if the communication is made with the user's computer, the user has to stay by the computer for long periods.
  • One possibility could be to make short connections every now and then, but the drawback with this solution is that the right instant to make an offer for a product may be missed.
  • a further problem is related to authentication of a buyer. Since the user may make binding offers through this telephone connection, there must be an authentication procedure before accepting the user to the electronic sale service. Before this kind of an authentication procedure is possible, there must be an agreement between the user and the electronic sale provider, and the electronic sale provider must give security codes for estabhshing the connections.
  • a further problem with the prior art solutions is that one needs to have a payment agreement with the auction service provider and a bank as described above. Therefore it may be too troublesome for ordinary potential users to try and start using the auction services.
  • the objective of the present invention is to create a solution for providing auctions wherein the above mentioned problems of the prior art solutions are reduced o ⁇ avoided.
  • One idea of the present invention is providing an auction where information on the products in sale and the present offers is transferred to potential buyers via digital television system.
  • This can be made e.g. in the television program, or by adding text in the program, on so-called teletext (or text TV) pages or on forward interaction channels of the digital television system.
  • the communication from the user to the auction management system can be accomplished by sending digital messages on the return channel of the digital television system using e.g. a user terminal that is connected to a so-called set top box.
  • the auction management system may comprise a display screen for showing said information on the products. This display screen can be imaged with video cameras for broadcasting on the digital television. This enables to create an entertaining auction program, where there is a display screen provided for a real time information on the products and offers.
  • ETS 300 800 [2] The European Telecommunications Standard number ETS 300 800 [2], known also as the DVB-RC (Digital Video Broadcasting - Return Channel) standard and compliant with the DAVIC (Digital Audio- Visual Council) 1.4 standard, lays down the general framework for implementing digital television.
  • the broadcast of a digital television system consists of transnritting so-called MPEG2-TS packets on an in- band broadcast channel.
  • MPEG2-TS packets on an in- band broadcast channel.
  • An uplink transmission channel as a part of bi-directional communication over a cable television network.
  • the transmission can be made, for example, within slots of TDMA frames according to a certain schedule.
  • a centrally located device known as the head-end composes the uplink transmission schedule and communicates the allocated uplink transmission time intervals to the cable modems.
  • the messages that comprise these allocations are known as MAC or Media Access Control messages, and they are complemented by the information of MAC Flags included in the downlink transmission.
  • One of the programming interfaces specified for the digital television is called Multimedia Home Platform MHP, which will probably be the most widely used interface.
  • the uplink return channel of a digital television system is mainly designed for viewers to take part in different questionnaire and voting, [2]. In such apphcations it is not necessary or desirable that information on the viewers' identities are collected or analysed. However, since a return channel can be allocated to a dedicated user, the user that is sending a message can be identified. It is also possible to identify the sender of a message from a identification part of a return channel message. This ability to identify the sender of a message can be utilized in the present invention; as it is also essential in providing a sales/auction service, that the auction management system can identify the customer or subscriber sending the message. It is also possible to use the digital television system for confhrning the acceptance of an offer to the buyer. It is possible to use either a broadcast channel of forward interaction channels for this purpose.
  • the inventive solution has several advantages over the prior art solutions.
  • the auction can be made a very entertaining online program using electronic mass media, and the viewers can have an immediate access to the auction.
  • the user is able to view an auction when there is the concerned digital TV channel and digital TV terminal available.
  • a user does not need to make a continuous data connection over a telephone line to the auction management system.
  • the user can also get instant information on a possible acceptance of a user's offer.
  • the user if the user wishes to make a new purchase offer, the user can send in real time a message with the required offer information. There is no need to make a new data transfer connection over a telephone line involving possible unsuccessful attempts causing a harmful delay in transn ⁇ tting the offer.
  • a further advantage with the present invention is that the payment of the bought products can be confirmed by a digital television operator.
  • the digital TV system operator and the auction service provider gets the identification of the subscriber connection where the message has been sent. This is reliable information on the subscriber and can therefore be used for confmning the buyer.
  • the payment can be added in the subscriber's television subscriber bill or the auction service provider can use the subscriber information for sending an invoice to the buyer. Therefore there is no need for separate payment agreements between a user, the auction service provider and a bank.
  • the only agreement that may be needed is an agreement between the auction service provider and a digital television system operator for transaction of the payments.
