  • FIG. 1 illustrates a system for providing a wireless LAN service using a rental digital television according to an embodiment of the invention.
  • The invention uses a wireless-LAN-embedded digital television to meet a combination of a demand for a digital television and a demand for more convenient environments for use of a wireless LAN.
  • For efficient spread of the wireless LAN, the invention combines a digital television which is a video medium with an access point which is a basic element of the wireless LAN and provides the combined digital television to a wired network subscriber (specifically, a lease service subscriber 110) and provides a method which allows a wireless LAN service subscriber 120 to receive the right to use the wireless LAN from the wired network subscriber and then to access the Internet through the wireless LAN.
  • The following is a description of features of this business model from the viewpoint of each of a service provider (specifically, a digital television lease service provider 100), the lease service subscriber 110, and the wireless LAN service subscriber 120.
  • First, the digital television lease service provider 100 leases a digital television for free or at low cost and provides a wireless LAN service, thereby making it possible to easily attract subscribers and also to create benefits from lease of digital televisions and sale of wireless LAN tickets (or access rights). In addition, it is possible to create benefits from use of the digital television, which is a high performance video medium, as an advertisement medium and also to create benefits from connection of various wireless devices to the Internet.
  • The lease service subscriber 110 can lease a digital television at low cost without directly purchasing the television and can also receive a wireless LAN service in near places.
  • The wireless LAN service subscriber 120 can use Internet services in a place where such a hybrid digital television is installed in the same manner as in a place where a conventional access point is installed and thus can use various services such as Internet services more conveniently.
  • FIG. 2 is a block diagram of a wireless-LAN-embedded digital television used in the system of FIG. 1.
  • The wireless-LAN-embedded digital television includes a DSL or cable modem 210, an access point 220, a TV tuner 230, and a display panel 240. The DSL or cable modem 210 is connected to a broadband network and operates in combination with the access point 220.
  • The DSL or cable modem 210, which is connectable to a wired network, and the access point 220 may be integrated and manufactured as a single modem board. This modem board includes a wired modem portion which is the DSL or cable modem 210 and a wireless modem portion which is the access point 220. The modem board includes a service server and an access management tool which are able to manage accesses by wireless LAN users. Through the service server and the access management tool, the digital television operates in combination with a management authentication server of a service provider on the Internet to perform a payment operation and an access authentication operation.
  • When the wireless-LAN-embedded digital television is turned on, a service server included in the modem 210 such as a DSL modem or a cable modem or the access point 220 accesses the management authentication server to determine whether or not a first user is a lease service subscriber. In addition, when a terminal of a second user accesses the access point, the service server included in the modem 210 accesses the management authentication server to determine whether or not a second user is a wireless LAN service subscriber.
  • The user can watch the digital television only after the modem 210 is activated to access the Internet and authentication is performed by the management authentication server of the service provider.
  • The access point 220, which is accessed by the terminal, is connected to a wired network.
  • The terminal of the second user can use wireless LAN services only after it accesses the wireless LAN and authentication is then performed by the management authentication server. To help the management authentication server perform the authentication process, a service server is run in the access point 220 or the modem 210 such as a DSL or cable modem. When a terminal of a wireless LAN service user has been connected to the access point 220, the access point 220 may operate in combination with the management authentication server to terminate the connection of the terminal if a specific connection condition is not satisfied, for example based on a given time period or range or specific dates.
  • The TV tuner 230 outputs a received broadcast signal to the display panel 240. The received broadcast signal includes a general terrestrial signal, a satellite broadcast signal, a cable broadcast signal, etc.
  • FIG. 3 illustrates a structure for connection of the wireless-LAN-embedded digital television used in the system of FIG. 1 to a backbone network.
  • A wireless-LAN-embedded digital television 300 is leased to a first user who desires to use a digital television. When the digital television 300 is powered on, a TV tuner 230 included in the digital television 30 is activated if the first user is a lease service subscriber.

At a specific time or under a specific condition, the recorded information is forcibly transmitted to the display panel 400 to be output through it.
  • At any other time, the user can freely watch broadcasts on the digital television. The advertisement image information may be output instead of all or part of the TV image at a specific time or under a specific condition. The advertisement image information is automatically communicated between the packet receiver 410 and the advertisement image server 490. Thereafter, regardless of whether it is connected to the network, the modem automatically broadcasts the advertisement image information through the display panel 400, irrespective of any manipulation done by the lease service subscriber. Although advertisement image information carrying the same advertisement may be collectively transmitted and broadcast to digital televisions, a specific advertisement may be individually transmitted and broadcast to a specific digital television as needed, thereby providing targeted advertisement. To accomplish this, the server has a list of serial numbers of digital televisions and transmits desired advertisement image information to a digital television identified with its serial number.
  • The system of FIG. 4 may also be used to provide various services, examples of which include operation of a digital content shopping mall and a Voice over Internet Protocol (VoIP) phone using a wireless LAN.
  • In the case where the system is applied to the VoIP phone service, a VoIP phone that can access a wireless LAN can access the management authentication server 330 and the management authentication server 330 can perform call management, specifically, management of call durations, call rates or fees, and the like of the phone.
  • The phone of the third user is incorporated into VoIP software.
  • When the phone accesses the access point 220, a service server 210 accesses the management authentication server 330 to determine whether or not the third user is an Internet phone service subscriber.
  • If the third user is an Internet phone service subscriber, the access point 220 provides an Internet phone service to the phone of the third user.
  • In the case where the system is applied to the shopping mall service, the management authentication server 330 operates to provide shopping mall functions in addition to the above-mentioned advertisement functions, so that it can sell digital content (for example, MP3, movie, and e-book content) through the Internet.
  • If a fourth user inputs purchase information to purchase digital content represented by a displayed image to a terminal of the fourth user, then the terminal accesses the access point 220.
  • If the terminal of the fourth user accesses the access point 220, then the management authentication server 330 requests confirmation of the purchase information from the terminal of the fourth terminal. When the fourth user has confirmed the purchase information, the management authentication server 330 transmits digital content according to the purchase information to the terminal of the fourth user. The system may be designed to use an external server other than the management authentication server 330 to request confirmation of the purchase information and to transmit digital content according to the purchase information to the terminal.
  • FIG. 5 is a flow chart of a method for providing a wireless LAN service using a rental digital television according to another embodiment of the invention.
  • First, power is supplied to a wireless-LAN-embedded digital television leased to a first user or the power of the digital television is turned on by operating a power button (510).
  • When the digital television is turned on, an access point is initialized (520).
  • The access point initialization establishes a connection to the wired network. Then, if the network is ready (530), a service server included in the wireless-LAN-embedded digital television is used to access the management authentication server (540). If the network is not ready (530), the operation of the digital television is stopped and the access point is reinitialized (520).
  • When the digital television has been connected to the management authentication server, it is determined whether or not the first user is a lease service subscriber (550). Preferably, this step (550) includes the step of recording information of the first user including a lease fee and registering the first user as a lease service subscriber at the management authentication server when the first user has made a digital television lease request.
  • If the first user is not a lease service subscriber, the digital television again accesses the management authentication server (540) after waiting for a predetermined time (555).
  • If the first user is a lease service subscriber, a TV tuner of the wireless-LAN-embedded digital television is activated (560).
  • Finally, the access point of the wireless-LAN-embedded digital television is used to provide a wireless LAN service to a terminal of a second user (570).
  • Preferably, this step (570) includes the step of adjusting the lease fee according to the number of times and how long terminals access the access point at the management authentication server.
  • Each digital television has a fixed product number. When power is supplied to the digital television, its modem board accesses a management authentication server of a service provider through the Internet. After performing authentication, the management authentication server transmits a message, which contains information indicating whether or not the authentication is successful, to the digital television. The digital television gets a control right according to the message.
  • FIG. 6 is a detailed flow chart of the wireless LAN activation step (570) of FIG. 5.
  • A process for authenticating a wireless LAN service subscriber is explained in the description of FIG. 6. First, a terminal of a second user detects a wireless LAN (specifically, a wireless LAN access point) that can be accessed by the terminal (610).
  • Then, the terminal accesses the detected access point using a web browser of the terminal (615). After detecting the access by the terminal of the second user (620), the wireless LAN access point transmits an authentication webpage to the terminal so that the authentication webpage is displayed on the web browser of the terminal (625).
  • The second user logs in through the web browser (630). If it is determined through the login process that the terminal of the second user has a ticket (or access right), the wireless LAN access point permits the access of the terminal to the Internet (or public network) through the wireless LAN after performing authentication processes (640-659). If the terminal of the second user has no ticket (or access right), the second user signs up (630) and purchases a ticket (or access right) through payment (655).
  • Thereafter, the terminal can again access the access point to use the Internet in the same method as described above. An available time period or range or available dates are defined in the ticket. If the ticket is used for longer than a specific time, the wireless LAN access point determines whether or not to terminate the connection of the terminal while periodically checking how long the terminal has been connected to the Internet (680).
  • FIG. 7 is a detailed flow chart of the ticket purchase step (655) of FIG. 6.
  • The flow chart of FIG. 7 illustrates a payment process for obtaining a ticket (or access right) in the wireless LAN access process. First, a wireless LAN user receives information from the management authentication server through the access point (i.e., the wireless-LAN-embedded digital television). When the user determines, based on the received information, that a ticket (access right) of the user is expired or its remaining period (or time) is shorter than required, the user makes a payment attempt request in order to access the Internet (710). Here, the management authentication server informs the user of the remaining period of the ticket (access right) (720-740) and awaits payment by the user. The user inputs and transmits payment information to the server (750) to extend the period of the ticket of the user (760). When this process is completed, the management authentication server updates information of the ticket of the current user of the access point which is an intermediate medium (770) and the access point permits access of the terminal to the Internet according to the updated information (780).
  • FIG. 8 is a flow chart of a method for providing a wireless LAN service using a rental digital television according to another embodiment of the invention.

Then, it is possible to provide an inexpensive voice communication service through a wireless LAN module of the digital television.
  • If a third user turns on the phone or picks up its receiver (810), the phone accesses the management authentication server through the wireless LAN to which the phone has been connected (815). Here, if the phone of the third user accesses the access point, it accesses the management authentication server using a service server included in the wireless-LAN-embedded digital television (815).
  • The management authentication server checks a ticket of the third user to determine whether or not the third user is an Internet phone service subscriber (820-875).
  • Here, the phone transmits authentication information required to check the ticket to the management authentication server (830). When the management authentication server completes authentication of the ticket (835), the phone displays the authenticated ticket information and is then ready for sending a call (840 and 860).
  • When the third user attempts to send a call by pressing a button on the phone (865), the management authentication server checks the authenticated ticket (870) and determines whether or not the third user is an Internet phone service subscriber (875).
  • If the third user is an Internet phone service subscriber, the management authentication server provides an Internet phone service to the phone of the third user (880).
  • The following are some technical features required to accomplish such a service.
  • The VoIP phone is basically able to access the wireless LAN. The VoIP phone is activated after being connected to and authenticated by a management authentication server that is installed on the Internet to operate digital televisions.
  • The management authentication server has a list of VoIP phones and stores information regarding the respective rights to use the VoIP phones. A billing process involves a ticket purchase process (850) in which the user purchases a ticket (or use right) through the management authentication server using another terminal such as a PC connected to the wireless LAN in a similar manner to the payment process. As needed, the VoIP phone may be connected to a public telephone network to make it possible to make a phone call using the VoIP phone.
