The present invention relates to service provision, and more particularly, to a method and system for providing an additional service associated with a channel that a user is watching through a broadcast receiver using RFID-based technology.

Conventionally, bar codes are attached to almost all objects, such as goods, objects, facilities, animals, plants, products, and inventory, to record and utilize information and prices of each individual. However, there are various limitations of the barcode, i.e., the barcode must be within the laser range of the reading device when reading, and it cannot record a variety of information, and there is a high possibility of damage, alteration and forgery. In addition, there is a high cost and inefficient problems, such as a lot of inconvenience for both the consumer and the producer for reasons such as a lot of time and cost when reading.

On the other hand, in order to improve the above problems, a new RFID technology related to electronic tags that can replace barcodes has been proposed, and attaches electronic tags to objects such as goods, objects, facilities, animals, plants, products, and inventory. In order to efficiently manage and utilize various types of information, government agencies, companies, producers, distributors, and logistics companies are actively pursuing.

In general, an RFID system consists of three main components: a transponder, a so-called electronic tag, an electronic tag reader, and a host computer or a device capable of processing data. Such an electronic tag has various uses. And an antenna capable of receiving a frequency transmitted from an IC chip and an electronic tag reader, which is designed to meet the needs. When the electronic tag passes within the frequency effective range of the antenna in the electronic tag reader, it detects a signal from the electronic tag reader, and sends information data stored in the electronic tag to the electronic tag reader. The electronic tag reader includes an antenna for transmitting or receiving radio waves and a portion of an electronic circuit that transmits or receives radio waves toward the electronic tag. A semiconductor chip in the electronic tag reader changes a signal coming from an electronic tag or The signal is verified and stored in memory, which is a storage device, and later transmitted if necessary. The electronic tag reader receiving the data from the electronic tag converts the data into a digital signal and transmits the data to the host computer through a wired or wireless communication network. In the RFID technology using the electronic tag, the electronic tag must have a separate electronic tag reader to recognize the information of the electronic tag. However, at present, there is almost no way for consumers or users of individuals or companies to carry the electronic tag reader so that the information of the electronic tag can be utilized.

Recently, however, a method of attaching an RFID tag reader / writer to a user terminal such as a mobile communication terminal has been attempted. Therefore, there is a need to provide an application service using an electronic tag reader mounted on a user terminal.

Accordingly, the present invention for solving the above problems is to provide a method and system for providing a service using an RFID-based technology that can provide an additional service associated with the broadcast program that the user is watching using the RFID-based technology. will be.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that the invention is not intended to be limited to the particular embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. Like reference numerals are used for like elements in describing each drawing.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Hereinafter, the same reference numerals are used for the same components in the drawings, and duplicate descriptions of the same components are omitted. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

Hereinafter, when an RFID tag is attached or embedded in a broadcast receiver and a user requests to provide an additional service for a broadcast program provided through the corresponding broadcast receiver, the user terminal reads tag information of the corresponding RFID tag and adds it. The server may be connected to the server providing the service to receive and output the additional service. In this specification, it is assumed that the broadcast receiver is the set-top box 110 in order to facilitate understanding and explanation.

1 is a block diagram schematically illustrating a system for providing an additional service associated with a broadcast program being viewed by a user using an RFID based technology according to an embodiment of the present invention.

Referring to FIG. 1, a system 100 for providing an additional service for a broadcast program according to the present invention includes a set top box 110, a service providing server 120, and a user terminal 130.

The set-top box 110 includes one or more RFID tags 203, and after reconstructing and signal processing the original video signal and audio signal of the digital broadcast program of the MPEG2 transport stream received through the satellite broadcasting antenna The video and audio signals are outputted and displayed on a television, so that the user can watch a desired broadcast program.

In addition, the set-top box 110 transmits the information on the broadcast program output through the television and identification information of the set-top box 110 to the service providing server 120 through the communication network. Here, when the channel is changed by the user, the set-top box 110 may transmit the information according to the changed (or selected) channel to the service providing server 120 through the communication network according to the channel change requested by the user. . That is, since one broadcast program is provided through an arbitrary channel, it will be described using a channel or a broadcast program selectively according to the context.

The RFID tag 203 has tag information about a specific object embedded therein, and when the tag information enters within an effective distance of a specific frequency, the tag information is wirelessly read by an electronic tag reading apparatus such as an RFID reader 310.

That is, the RFID tag 203 is attached to the set top box 110 to embed tag information which is specific information about the set top box 110. Here, the tag information may include one or more of the identification information of the corresponding set-top box 110 and the connection information for access to the service providing server 120 that provides information on any broadcast program. Here, the identification information may be in the form of numbers or letters.

For example, assume that the RFID tag 203 includes only identification information for the set top box 110. The user terminal 130 obtains tag information (for example, identification information) from the RFID tag 203 using the provided RFID reader 310 and transmits the tag information to an object directory service (ODS) server (not shown). . Here, the ODS server performs a function of providing information necessary for obtaining an information resource corresponding to the identification information expressed in the form of a number (or a letter). For example, if a domain name server (DNS) performs the function of finding an "IP address" for a "name address" (for example, ktf.com), then the ODS server may be responsible for identifying the information resource corresponding to that identification. Performs a function to find uniform resource identifier (URI) information. In this case, the URI information may provide an IP address for a server (for example, the service providing server 120) that provides information corresponding to the identification information, a directory name and file name where the information resource is stored, a communication protocol, and the like. It contains all the information needed to obtain arbitrary information from the server 120.

For another example, assume that both the identification information of the set-top box 110 and the access information for accessing the service providing server 120 are stored in the RFID tag 203. The user terminal 130 acquires the corresponding tag information from the RFID tag 203 using the RFID reader 310, accesses the service providing server 120 using the access information, and then uses the corresponding identification information. The set top box 110 may be identified. The service providing server 203 may extract information about a broadcast program provided through the corresponding set top box 110 and provide the extracted information to the user terminal 130 through a communication network.

As another example, the RFID tag 203 may include identification information on the set-top box 110, access information to the service providing server 120, or information on a channel. For this reason, the set-top box 110 may record the information on the changed channel in the RFID tag 203 when the user selects or changes a certain channel. In this case, the user terminal 130 may read the tag information of the RFID tag 203 embedded in or attached to the set top box 110 and connect to the service providing server 120 using the tag information. The service providing server 120 may extract information about a channel included in the tag information and transmit a corresponding additional service to the user terminal 130.

For another example, the set top box 110 may embed or attach one or more RFID tags corresponding to each channel. Tag information of each RFID tag may include channel identification information, time information, and access information for the service providing server 120 for each channel. When the user selects or changes an arbitrary channel, the set-top box 110 may activate only an RFID tag corresponding to the selected or changed channel. For this reason, when an additional service for a channel being watched is requested from the user, the user terminal 130 may read only tag information of the corresponding active RFID tag.

For example, suppose a user is watching any digital broadcast program via a television. In this case, the user requests detailed information (eg, actor actor information, actor actor costume information, broadcast place information, jewelry information, food information, etc.) about the broadcasting program that the user is watching through the user terminal 130. In this case, the user terminal 130 reads tag information from the RFID tag 203 attached to the set top box 110 using the RFID reader 310. In addition, the user terminal 130 may access the service providing server 120 through the communication network using the read tag information and receive and output content information about the broadcast program being viewed through the television.

The service providing server 120 is connected to the set top box 110 through a communication network, and receives and stores information about a broadcast program being viewed by the user from the set top box 110. As described above, the service providing server 120 may also receive identification information on the corresponding set-top box 110 and may map and store the information on the corresponding broadcast program.

In addition, the service providing server 120 provides any additional service to the user terminal 130 through a communication network.

For example, when the user terminal 130 requests to provide information by accessing the service providing server 120 using the tag information, the service providing server 120 uses the corresponding tag information to view a broadcast program that the user watches. Extract one or more contents for and transmit the same to the user terminal 130 through a communication network. Here, the tag information may include identification information of the set top box 110 and access information to the service providing server 120 as described above.

In another example, the service providing server 120 receives and stores channel information selected or changed from the set top box 110 and identification information of the set top box 110 according to a user's channel selection or change request, and stores each channel in real time. The viewer rating of the channel may be calculated and provided to a broadcasting station (not shown) or the user terminal 130 connected through a communication network.

The user terminal 130 is a mobile communication terminal including a PCS, PDA, smart phone, etc. capable of Internet through a communication network 50 such as a mobile communication network and a wired communication network, a wireless LAN (LAN) terminal, a Bluetooth terminal, a portable device. Refers to all terminals capable of accessing the Internet, such as an internet terminal. In the present specification, a description will be made on the assumption that the user terminal 130 is a mobile communication terminal. However, it will be more apparent through the following description that all terminals capable of the Internet can be equally applied.

In addition, the user terminal 130 is mounted or attached to the RFID reader 310 that can read the RFID tag 203. The user terminal 130 reads the tag information from the RFID tag 203 attached to the set-top box 110 when a content request related to the broadcast program being viewed is requested by the user. In addition, the user terminal 130 may receive and output one or more content information about the broadcast program being viewed by accessing the service providing server 120 through the communication network using the read tag information. In this specification, the user terminal 130 may be equally applicable to any terminal equipped with or attached to the RFID reader 310 and capable of internet.

Here, the RFID reader 310 starts an RFID tag and transmits an electromagnetic field for supplying power to the RFID tag 203. In addition, the RFID reader 310 may obtain tag information by decoding a signal transmitted and received through an RFID based air interface. In the present specification, a method for wireless communication between the RFID reader 120 and the RFID tag 220 is obvious to those skilled in the art, so a detailed description thereof will be omitted.

Here, the tag information may include identification information of the set-top box 110 and access information for access to the service providing server 120 that provides an additional service for any broadcast program. In addition, the access information may be URL and domain information corresponding to the corresponding service providing server 120.

In the present specification, it is assumed that the RFID tag 203 is attached or embedded in the set-top box, but it is obvious that the RFID tag 203 may be attached or embedded in the television.

The data transceiver 207 performs a function of transmitting and receiving data with the service providing server 120 through a communication network under the control of the controller 240. For example, the data transmitting / receiving unit 207 may include information about a channel (ie, a broadcast program) selected (or changed) by the user under the control of the control unit 240 together with identification information of the set-top box 110. Performs a function of transmitting to the service providing server 120.

The tuner 210 selects a radio wave corresponding to the selected channel from the user and transmits the radio wave to the demodulator 215.

The demodulator 215 demodulates a signal (that is, a radio wave signal) input through the tuner under control of the controller 240 and transmits the demodulator 215 to the demux 220.

The demux 220 performs a function of parsing the input audio, video and data demodulated by the demodulator 215 to separate the data according to the type and output the decoder 220 to the decoder 220. Although only one decoder is illustrated in the figure, it is obvious that the decoder 220 may be embodied as a video decoder, an audio decoder, an information decoder, or the like according to a function each performs. Here, the data type may be video data, audio data, or information data.

The decoder 220 decodes each of the data separated and input by the demux 220 under the control of the control unit 240 in accordance with a predetermined method so that the original audio signal, video signal, and data signal ( Hereinafter, for convenience of understanding and explanation, the " information data " The decoder 220 performs a function of outputting each data through the data output unit 230 or storing the data in the memory 235 under the control of the controller 240. In FIG. 2 one decoder 220 is shown to decode video, audio and information data but may have a decoder (eg, a video decoder, an audio decoder, an information data decoder, etc.) to decode each data. Can be.

The memory 235 may include a volatile memory and a nonvolatile memory. In addition, the memory 235 stores identification information about the set-top box 110. The memory 235 records each video data, audio data, and information data decoded by the decoder 220 by the control of the controller 240. In addition, the memory 235 stores an algorithm for operating the set-top box 110 according to the present invention.

The data output unit 230 outputs video and / or audio data stored in the memory 235 under the control of the controller 240, or outputs information data in an OSD (on screen display) format. Here, the OSD refers to displaying information necessary for a user on a screen by a display device (eg, a monitor, a television, etc.) connected to the data output unit 230 without a separate image signal input. Of course, the data output unit 230 may output the respective data decoded by the decoder 220 to the display apparatus under the control of the controller 240.

The control unit 240 is an internal component of the set-top box 110 according to the present invention (for example, tuner 210, demodulator 215, demux 220, decoder 220, data output unit 230 ), The memory 235, etc.).

In addition, when a selection command for a certain channel is input by the user, the control unit 240 transmits the information about the selected channel to the service providing server through the data transmitting / receiving unit 207 together with identification information of the set-top box 110. Send to 120.

As described above, the RFID reader 310 recognizes the RFID tag 203 that has entered a valid distance by generating a specific frequency and performs a function of reading tag information in the RFID tag 203.

The display unit 315 is a means for displaying image data of the additional service and broadcast information related to the additional service under the control of the controller 320. For example, the display unit 315 may be a liquid crystal display (LCD).

The sound output unit 320 is a means for outputting the received sound corresponding to the additional service provided from the service providing server 120. For example, the sound output unit 320 may be a speaker.

The input unit 325 is a means for receiving a control command, a function selection command (for example, an additional service display command, a purchase command, etc.) for controlling the operation of the user terminal 130 from the user. For example, the input unit 325 may be implemented as a plurality of key buttons (for example, menu keys, call keys, confirmation keys, keys for accessing the Internet, terminal number keys, additional function keys, etc.) or in the form of a touch screen. Can be implemented.

The transceiver 330 performs a function of transmitting and receiving data with the service providing server 120 through a communication network. For example, the transmitter / receiver 330 may access the service providing server 120 by using the tag information under the control of the controller 240 and request an additional service for the broadcast program being watched through the television. The transceiver 330 may receive an additional service according to the request of the additional service from the service providing server 120 through a communication network and output the additional service to the display unit 315 under the control of the controller 340.

For example, when a request for providing an additional service for a broadcast program being watched by a user is input, the controller 340 controls the RFID reader 310 to start the RFID tag 203 attached to the set top box 110. Receive tag information. As described above, the tag information may include identification information of the set-top box 110 and access information for access to the service providing server 120 that provides additional services for the broadcast program. Accordingly, the controller 340 may access the service providing server 120 using the tag information input through the RFID reader 310 and request to provide an additional service for the corresponding broadcast program.

That is, the service providing server 120 periodically receives and stores identification information about the set top box 110 and information about a broadcast program that the user is watching through the set top box 110 from the set top box 110. . Therefore, when tag information is received from the user terminal 130, the identification information of the set-top box 110 included in the tag information is extracted to recognize a broadcast program that the user is watching through the set-top box 110. Can be. In addition, the service providing server 120 may extract an additional service for the broadcast program that the user is watching and provide it to the user terminal 130 through a communication network.

The memory 335 stores tag information read by the RFID reader 310 and data received from the service providing server 120. In addition, according to an embodiment of the present invention, the memory 335 may store related data so that each component of the user terminal 130 can be operated.

The control unit 340 is a component of the user terminal 130 according to the present invention (for example, RFID reader 310, display unit 315, sound output unit 320, input unit 325, transmission and reception) The unit 330 and the memory 335 are controlled. In addition, the control unit 240 performs a function of controlling to receive and output an additional service by accessing the service providing server 120 using the tag information obtained through the RFID reader 310.

For example, when the tag information is read from the RFID tag 203 attached or embedded in the set-top box 110 through the RFID reader 310, the controller 340 uses the connection information included in the read tag information. After accessing the service providing server 120 by using the identification information of the set-top box 110 included in the tag information, the broadcast program being output (ie, watched by the user) through the set-top box 110 It may be controlled to receive and output the additional service for.

4 is a flowchart illustrating a method of providing an additional service associated with a broadcast program being viewed using an RFID-based technology in a user terminal according to an embodiment of the present invention. Hereinafter, as described above, the set-top box 110 includes identification information about the set-top box 110 and access information for accessing the service providing server 120 that provides an additional service for any broadcast program. It is assumed that the RFID tag 203 in which the tag information is embedded is attached or embedded. In addition, when the user receives a selection (or change) command for a certain channel by the user, the set-top box 110 displays information about the selected (or changed) channel (ie, a broadcast program). It transmits to the service providing server 120 with the information. Accordingly, the service providing server 120 may recognize any broadcast program provided through any set top box 110.

In step 410, when a request for information on a broadcast program provided through the set-top box 110 is input from the user, the user terminal 130 is embedded in (or attached to) the set-top box 110 using the RFID reader 310. The RFID information 203 is read to obtain tag information.

In operation 415, the user terminal 130 extracts access information for accessing an arbitrary service providing server 120 from the obtained tag information. Here, the access information may be any one of URL or domain information as described above.

In operation 420, the user terminal 130 accesses the corresponding service providing server 120 through the transceiver 330 using the access information and transmits identification information of the set-top box 110 included in the tag information.

The user terminal 130 obtains tag information (for example, identification information) from the RFID tag 203 using the provided RFID reader 310 and transmits the tag information to an object directory service (ODS) server (not shown). . Here, the ODS server performs a function of providing information necessary for obtaining an information resource corresponding to the identification information expressed in the form of a number (or a letter). For example, if a domain name server (DNS) performs the function of finding an "IP address" for a "name address" (for example, ktf.com), then the ODS server may be responsible for identifying the information resource corresponding to that identification. Performs a function to find uniform resource identifier (URI) information. In this case, the URI information may provide an IP address for a server (for example, the service providing server 120) that provides information corresponding to the identification information, a directory name and file name where the information resource is stored, a communication protocol, and the like. It contains all the information needed to obtain arbitrary information from the server 120.

For another example, suppose that the RFID tag 203 stores both identification information of the corresponding set-top box 110 and access information for accessing the service providing server 120. The user terminal 130 acquires the corresponding tag information from the RFID tag 203 using the RFID reader 310, accesses the service providing server 120 using the access information, and then uses the corresponding identification information. The set top box 110 may be identified. The service providing server 203 may extract information about a broadcast program provided through the corresponding set top box 110 and provide the extracted information to the user terminal 130 through a communication network.

As another example, the RFID tag 203 may include identification information on the set-top box 110, access information to the service providing server 120, or information on a channel. For this reason, the set-top box 110 may record the information on the changed channel in the RFID tag 203 when the user selects or changes a certain channel. In this case, the user terminal 130 may read the tag information of the RFID tag 203 embedded in or attached to the set top box 110 and connect to the service providing server 120 using the tag information. The service providing server 120 may extract information about a channel included in the tag information and transmit a corresponding additional service to the user terminal 130.

For another example, the set top box 110 may embed or attach one or more RFID tags corresponding to each channel. Tag information of each RFID tag may include channel identification information, time information, and access information for the service providing server 120 for each channel. When the user selects or changes an arbitrary channel, the set-top box 110 may activate only an RFID tag corresponding to the selected or changed channel. For this reason, when a supplementary service is provided for a channel being watched by a user, the user terminal 130 reads the tag information of the active RFID tag and accesses the service providing server 120 using the corresponding tag information. A request for providing an additional service corresponding to the channel being watched may be requested.

The service providing server 120 extracts a broadcast program mapped to the identification information of the set-top box 110 by using the received identification information of the set-top box 110 and then stores an additional service associated with the corresponding broadcast program through a communication network. Provided to the user terminal 130.

In operation 425, the user terminal 130 receives and outputs an additional service from the service providing server 120 through a communication network.

To the set-top box 510. Accordingly, the set-top box 510 provides the service tagging server 520 with the acquired tag information and the information on the channel selected (or changed) by the user (that is, the information on the channel being viewed by the user) through the communication network. To send. When the user terminal 530 accesses the service providing server 520 through the wireless Internet, the service providing server 520 extracts an additional service for the corresponding broadcast program and transmits the additional service to the user terminal 530 through the communication network.

6 is a flowchart illustrating a method of providing an additional service for a broadcast program that a user is watching by using an RFID-based technology according to another embodiment of the present invention. Hereinafter, when the user terminal 530 having the built-in or attached RFID tag 535 is close to the set-top box 510 in order to receive an additional service for a broadcast program that the user is watching, the set-top box 510 is a corresponding RFID. The tag is read, and accordingly, the service providing server 520 transmits the additional service according to the channel information being viewed to the user terminal 510 in detail.

In operation 610, the set-top box 510 reads tag information of the RFID tag 535 embedded or attached to the user terminal 530 located in the proximity by using the built-in or attached RFID reader 515. Here, the tag information may be at least one of identification information of the corresponding user terminal 530 and access information to the service providing server 520.

If any channel is selected or changed by the user (step 615), the set-top box 510 transmits the selected or changed channel information and read tag information to the service providing server 520 through the communication network (step 620). . Here, when the tag information is read, the set-top box 510 may transmit the currently viewed channel information along with the tag information even if any channel is not selected or changed by the user.

In operation 625, the service providing server 520 stores channel information and tag information received from the set-top box 510. As such, the service providing server 520 receives channel information and tag information (for example, identification information of the user terminal 530) from the set-top box 510 to be provided by any user terminal 530. The additional service according to the channel can be recognized.

In operation 630, the user terminal 530 accesses the service providing server 520 at the request of the user and requests for additional service. Here, since the service providing server 520 recognizes channel information corresponding to an arbitrary user terminal 530, when the corresponding user terminal 530 accesses, the user terminal 530 provides an additional service corresponding to the channel information. (Step 635). Accordingly, the user terminal 530 may receive and output an additional service.

As described above, by providing a method and a system for providing a service using an RFID-based technology according to the present invention, there is an effect that a user can provide an additional service associated with a broadcast program (ie, a channel) being watched.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that the invention may be varied and varied without departing from the scope of the invention.
