Description

  The present invention relates to a one-segment broadcasting system, a channel list distribution server, and a receiving method using a mobile communication terminal having a one-segment broadcasting reception function.

  A mobile communication terminal such as a mobile phone terminal or a PHS terminal is provided with a one-segment reception function so that digital broadcasts can be received, and a one-segment broadcast system is operated. However, one-segment broadcasting has a limited receivable area, and it has been difficult for a mobile communication terminal to tune to a frequency for receiving broadcasting in each area, that is, to acquire and set reception channel information.

  The mobile communication terminal can receive the current location information acquired by receiving radio waves from GPS satellites by accessing a server that stores and stores receivable area information of one-segment broadcasting for each region via the mobile communication network. A method for acquiring channel information of one-segment broadcasting has been proposed (for example, Patent Documents 1 and 2).

  However, this method has a problem that channel information for one-segment broadcasting cannot be acquired in a place where GPS radio waves cannot be received such as in a building.

  On the other hand, in a closed area where such external radio waves cannot be received, the use of one-segment broadcasting in a specific area different from general commercial broadcasting called area one-segment broadcasting is permitted.

  In addition, many cell phones and PHS models are equipped with a one-segment reception function, and area one-segment broadcasting that distributes unique video content in a specific area such as a downtown area or an event venue has attracted attention. Area One Seg uses a different frequency from general One Seg broadcasting. Therefore, it is necessary to set a unique channel that can be seen only in the area, not a channel prepared as a preset for a 1Seg mobile phone.

  As a method of setting the reception channel for this Area One Seg, access to a mobile phone site for frequency setting using the three-way communication function of “Osaifu-Keitai” (registered trademark) using a non-contact IC card built into the mobile phone terminal However, there is a mechanism for automatically setting the one-seg frequency on the mobile phone side (for example, Non-Patent Document 1).

  In this method, when a user holds a mobile phone terminal equipped with “Osaifu-Keitai” over a dedicated reader / writer in the venue and clicks a link in a designated mobile phone site, Area One Seg can be viewed.

  However, even in this method, the installation location of the dedicated reader / writer is limited. If the user does not go to the location, there is a problem that the channel cannot be set, and a large number of readers / writers must be installed, resulting in an expensive problem.

  Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a configuration diagram of an area one-segment broadcasting system according to an embodiment of the present invention.
Here, the configuration and operation of the one-segment broadcasting system will be described by taking as an example a case where a mobile phone system using a mobile phone terminal as a mobile communication terminal is a mobile communication system. The present invention is also applicable to wireless communication systems such as PHS systems and WiMAX.

  In FIG. 1, an area one-segment broadcasting system includes a mobile phone base station 1 (hereinafter abbreviated as BS1), a relay device 2, a channel list distribution server 3 (hereinafter abbreviated as distribution server 3), a network 4, and a mobile phone terminal 5. , A high-frequency signal transmission path (abbreviated as RF signal link 6) 6 and a GPS satellite 7.

  The network 4 transmits information between the BS 1, the relay device 2, and the distribution server 3, such as an IP network (or the Internet), a mobile communication network such as a mobile phone network, or a carrier network. It is configured by either or a combination thereof.

  The mobile phone terminal 5 has a function of receiving a broadcast for the area one seg and receiving a radio wave from the GPS satellite 7 and receiving a radio wave from the one seg broadcasting station 8 and receiving a radio wave from the GPS satellite 7. I have.

  The relay device 2 transmits / receives a mobile phone radio wave to / from the mobile phone terminal 5 and relays it to / from the BS 1, and a one-segment broadcast radio wave in the vicinity. And an area one-seg transmitter 22 for transmitting.

  The RF head 21 is connected to the BS 1 using a high-frequency signal transmission path (abbreviated as an RF signal link 6) 6 such as a wireless link, a coaxial cable, or an optical fiber, and external radio waves in a building or an underground shopping center. It is a wireless communication repeater (relay) means for enabling communication between the mobile phone terminal 5 and the BS 1 in a place where the signal does not reach (referred to as a closed area). The RF head 21 is configured by a ROF (Radio on Fiber) system in which the RF signal link 6 is connected by an optical fiber, and is typically installed in units of floors in a building.

  Further, both cover areas of the transmission radio waves of the RF head 21 and the area one-segment transmitter 22 are adjusted to be the same. In addition to adjusting the transmission output with a non-directional antenna to align both cover areas, the directional antenna is also used to reduce the difference in propagation characteristics and cover area due to the difference in the wavelength of the radio wave transmitted between the mobile phone and Area One Seg broadcasting. It is effective to adjust the cover area using.

  The BS 1 monitors information (data) transmitted and received between the mobile phone terminal 5 and the distribution server 3 via the network 4 as well as a telephone control unit with the mobile phone network, and controls and manages the information. A data control unit 11 is provided.

  The data control unit 11 is a means provided for processing information relating to the application of the mobile phone system to which the BS 1 belongs and network management. Here, the data control unit 11 monitors signals transmitted and received by the mobile communication terminal 5 wirelessly. The base station or relay station identification information of the wireless communication is added to the reception request information to be transmitted to the distribution server 3 and notified.

  In particular, when the mobile phone terminal 5 and the BS 1 are wirelessly connected via the relay station (RF21), and the mobile phone terminal 5 cannot directly read the identification information (address) of the relay station from the address data of the radio link, In order to allow the distribution server 3 to add identification information so that the mobile phone terminal 5 can connect to the RF 21 to which the mobile phone terminal 5 is connected, the identification information is added when the distribution server 3 is installed in the BS 1 that owns the local information of the relay station. Easy to process.

  However, in addition to being provided in BS 1 as shown in FIG. 1, information on the relay station is previously notified to BS 1 to a device connected to the mobile communication network and a data control unit provided in mobile phone terminal 5. As described above, by setting application software for receiving one-segment broadcasting, it is installed in a central center (not shown) outside the BS 1 and shared with other base stations via the network 4 or provided in a mobile phone terminal. It may be a thing.

  The mobile phone terminal 5 notifies the BS 1, the distribution server 3, etc. of the own position information as described later so that the distribution server 3 can identify its current position. If the GPS satellite cannot be received, the distribution server 3 must be notified of information related to its current position. For this reason, identification information indicating the other party during wireless communication is notified to the distribution server 3 described later, but the notification function of identification information such as the relay station (RF head) 21 and BS1 is provided to this BS1 as described above. It may be a part of the data control unit 11 provided, or may be provided as the data control unit 11 inside the mobile phone terminal 5 as described later.

  Between the mobile phone terminal 5 and the distribution server 3, current position information such as positioning data from the mobile phone terminal 5, identification information of the relay device 2, etc. via a router, a server, etc., not shown in the network 4. Information (data) related to the is transmitted to the distribution server 3, and the channel information of the one-segment broadcasting station that can be received toward the mobile phone terminal 5 is transmitted from the distribution server 3. These communication control and processing are performed by application software that is transmitted and received on the standard communication protocol used in the mobile phone system by the communication IO 32 that performs communication via the network and the CPU 33 that controls the communication IO 32.

  In the distribution server 3, position information (positioning data) of latitude and longitude in advance as shown in FIG. 4 to be described later, and broadcast channel information broadcast by a one-segment broadcasting station that can be received corresponding to the position information are stored in the storage device 30. When the location information is received and stored in the broadcast station table 31 via the network 4 from the mobile phone terminal 5, the broadcast channel information that can be received at the location is retrieved and returned to the mobile phone terminal 5. It has a function to do.

  FIG. 2 is a functional block diagram for explaining the operation of the mobile phone terminal 5.

  In FIG. 2, the mobile phone terminal 5 is connected between the BS 1 and the broadcast receiving unit 51 that performs reception processing of the one-segment broadcasting, which are connected to each other by an internal bus or the like, via the RF head 21 of the relay device 2. A communication processing unit 52 that performs wireless communication, a GPS processing unit 53 that inputs a GPS reception signal and outputs positioning data to the communication processing unit 51, and a key button that inputs and outputs commands and information with the user of the mobile terminal 5 An I / O unit 54 (input / output unit 54) including a display, a speaker, and the like, and a control processing unit 55.

  Note that the GPS processing unit 53 may directly receive a GPS satellite signal, or may be supplied with a signal received by the communication processing unit 52 as a partial function.

  The control processing unit 55 monitors the internal bus and processes various information and data of the terminal including control information input / output via the key buttons of the I / O unit 54 and the communication processing unit 52 to control the operation of each unit. I do.

  When the mobile phone terminal 5 is located outside or at a position that does not interfere with the transmission / reception of radio waves with the outside such as the window of a building, the mobile phone terminal 5 directly transmits / receives radio waves from the mobile phone to / from the BS 1 and also receives radio waves from the GPS satellite 7. Can be measured. Then, the mobile phone terminal 5 is provided with a dedicated GPS satellite radio wave reception circuit, or via a communication processing unit 52 that transmits and receives radio waves from the mobile phone. The position information is acquired from the radio wave, and the control processing unit 55 performs control to send the acquired position information to the application device using the position information such as the distribution server 3 via the communication processing unit 52.

  On the other hand, when viewing the one-segment broadcasting by the broadcast receiving unit 51 built in the mobile phone terminal 5, the user inputs a setting corresponding to a predetermined operation such as designation of a broadcasting station from the I / O unit 54, and monitors the internal bus. The control processing unit 55 that has started activates the one-segment broadcasting reception mode.

  When receiving a broadcast station preset for input from the user, the broadcast receiving unit 51 is set and adjusted by the control processing unit 55 so as to receive a transmission radio wave from the broadcast station. If the mobile phone terminal 5 exists in the reception area of the one-segment broadcasting and can receive broadcast waves, the video / audio of the program to be viewed is output from the display or speaker of the I / O unit 54.

  On the other hand, if the preset broadcast station is in an area or area where reception is not possible, or if the preset or broadcast station to be received is not set, the control processing unit 55 determines the position by the GPS reception processing unit 53. Control is performed to acquire and send the received request information including GPS positioning information such as latitude and longitude and its own identification information to the distribution server 3 via the information communication processing unit 52 via the BS 1.

  Then, a list of broadcast stations that can be received as a reply to the reception request information from the distribution server 3 and the reception channel information are displayed on the display of the I / O unit 54 in a predetermined display format, and a designated input from the user is received. stand by.

  Positioning data between the mobile phone terminal 5 and the distribution server 3, wireless relay stations with which the mobile phone terminal 5 is wirelessly communicating, or connection destination information for notifying the base station, information such as a broadcast station list, etc. Data is transmitted and received using either the control channel or the data channel. This communication transmission control procedure is similar to the map information service by the mobile phone, and is executed by an application program installed in the mobile phone terminal 5 in advance.

  The distribution server 3 includes a storage device 30, a communication IO unit 32, and a CPU 33 that are connected to each other by an internal bus or the like. The communication IO unit 32 transmits / receives the reception request information and the return reception setting data to / from the mobile phone terminal 5 through the network 4, the BS 1, and the RF head 21 of the relay device 2. The communication IO unit 32 inputs / outputs data to / from the internal bus according to the protocol with the network 4, and the CPU 33 monitors the internal bus and executes an application program related to reception of one-segment broadcasting. To do.

  The storage device 30 stores a broadcast station list table 31 therein. The CPU 33 monitors the internal bus and reads the reception request information received by the communication IO unit and the broadcast station list table 31 stored in the storage device 30 and collates the received one-segment broadcast station that can be received by the mobile phone terminal 5. Control is performed such that reception setting data such as a channel is returned from the communication IO unit via the network 4.

  For one-segment broadcasts such as commercial broadcasts, the required broadcast station can receive from the mobile phone terminal 5 by the above method, but GPS satellite radio waves cannot be received in a closed area such as a house. The positioning server to be notified from the mobile phone terminal 5 cannot be acquired to the distribution server 3. Even if the transmission is performed without positioning data, the distribution server 3 cannot find the receivable broadcast station candidate by checking the list with the list because the current position of the mobile phone terminal 5 is unknown.

  As a method for making up for this drawback, the location information of each mobile phone base station is checked in advance, and the one-segment broadcasting stations that can be received corresponding to the cover area are listed and stored in the distribution server 3. When a list request for a one-segment broadcasting station that can be received without positioning data from the cover area of the mobile phone base station is received from the mobile phone terminal 5, the distribution server 3 reads the identification information of the mobile phone base station. Thus, a receivable broadcast station list extracted by collating the list with the identification information is returned.

  However, even with this method, the cover area of the mobile phone base station and the cover area of the one-segment broadcasting station are not originally compatible, so there are places where they are not the same and cannot receive broadcasts. In addition, there may be a plurality of broadcast station candidates, and a correct one-segment broadcast station candidate cannot be presented to the user. The one-seg broadcasting system according to the embodiment of the present invention eliminates these problems by making it possible to identify the position of the mobile phone by arranging both the cover area of the mobile phone provided by the relay device and the one-seg broadcasting in the closed area, It is also possible to realize area one-segment broadcasting that can be used for building events.

FIG. 3 is a diagram showing a part of a configuration of a control signal transmitted from the mobile phone terminal 5 to the distribution server 3 via the BS 1, and FIG. 4 is a distribution server in the one-segment broadcasting system according to the embodiment of the present invention. FIG. 5 is a flowchart for explaining an operation procedure between the mobile phone terminal 5 and BS 1 of the one-segment broadcasting system and the distribution server 3.
Hereinafter, the operation procedure of the one-segment broadcasting system according to the embodiment of the present invention will be described with reference to FIGS.
Input of a key button operation for selecting an application for receiving 1Seg broadcasting is performed on the I / O unit 54 of the user's mobile phone terminal 5 (ID: 5001 in this case) who wishes to view 1Seg broadcasting (step s1 in FIG. 5). ).

  In FIG. 3, the mobile phone terminal 5 operates according to the control / monitor signal format in accordance with the mobile phone system, at least the ID of the own terminal, for example, “XXXX-5001” as shown in FIG. Among the service menus being operated, “BR” indicating that it is a one-segment broadcasting reception menu and positioning data “N: 00 ° OX ′ E: XOX ° OX ′” as positioning data are received as reception request information for one-segment broadcasting. The control processing unit 55 performs control to transmit to the distribution server 3 via the BS 1 (step s2). If the GPS satellite signal cannot be received in a closed area or the like and the required positioning data cannot be obtained, “NO SIGNAL” (no GPS signal) data is transmitted as the positioning data.

  Then, the data control unit 11 of the BS 1 that has received the reception request information receives the identification information of the BS 1 that becomes the connection destination (the “connection destination BS RS” field in FIG. 3) of the mobile phone terminal 5 or the BS 1 (or the RF head). The identification information “# B3845” of 21) is further added to the reception information, edited to the low information, and transferred to the distribution server 3 (step s3).

  When the mobile phone terminal 5 is in the one-segment broadcast reception menu (one-segment reception mode), the information to be transmitted to the distribution server 3 includes the identification information of the BS 1 of the connection destination or the RF head 21 such as “#” of the BS 1. In the case of “B3845” or a relay radio station (RS), a method of directly transmitting “WES3456” may be used, and the distribution server 3 may read “# B3845”.

  For example, when the mobile phone terminal 5 directly transmits the identification information of the BS 1 or the RF head 21 of the connection destination, for example, the radio link between the BS 1 of the mobile phone network or the RF head 21 and the mobile phone terminal 5 is used. The connection information may be reflected in the application in the mobile phone terminal 5.

  In this case, the control processing unit 55 extracts the address information, that is, the identification information from the connection destination information of the wireless link formed between the mobile phone terminal 5 and the RF head 21 from the communication processing unit 52, and the distribution server For example, the address data of the RF head 21 that is the current call partner is described after the GPS prompt information.

  In other words, transmitting the current position information of the mobile phone terminal in addition to the identification information of the mobile phone terminal conventionally transmits GPS positioning data from the mobile phone terminal to the map information server, and from the map information server, It is also used in services that return map data to mobile phone terminals. Therefore, the control processing unit 55 of the mobile phone terminal 5 reads the address (identification information) of the RF head to which the mobile phone is connected into the GPS positioning data, and adds it to the distribution server 3 as reception request information. Can be easily realized.

  In the present embodiment, it is added that the identification information of the RF head 21 to which the cellular phone terminal 5 is connected is transmitted to the distribution server. However, for the location information exchange, the location of the cellular phone terminal 5 by GPS is specified. The detailed description is omitted because it may be similar to that of transmitting / receiving information related to the same.

  When the distribution server 3 receives the information shown in FIG. 3 (step s4), the server 3 stores the data relating to the service area of the one-segment broadcasting stored and stored in the broadcast station list table 31 here. The comparison is made and the result is returned to the mobile phone terminal.

  In FIG. 4, the channel data, the installation position, the receivable area, the identification number of the RF head of the installation relay device (RS) (in the column of “RS ID”) corresponding to the name of the broadcasting station performing the one-segment broadcasting, For example, “A0001”, “ch # a1”, “N: 0 ° 00′E: XXX ° XX ′”, “Zone A01”, “blank”, or “E2003”, “ch # e3” in (a). ”,“ ABC DEPT 9F ”,“ IX-WES ”,“ WES3456 ”, and the like are stored in the broadcast station list table 31 in advance.

  FIGS. 4A and 4B are one-segment broadcasting stations that perform general wide-area services. From the transmission antenna at “N: 00 ° OO′E: XXX ° XX ′”, the shape of the cover area is shown here. Etc., although not shown in detail, provides a service that can be received within the range of “Zone A01”. The cover area such as “Zone A01” can be collated with the current positioning data of the mobile phone terminal 5 acquired by GPS by describing (mapping) the shape in cooperation with the latitude and longitude information on the map. May be.

  The distribution server 3 stores the mapping data of the cover area as a database (not shown). A receivable one-segment broadcasting station can be extracted by comparing the mapping data with the current positioning data of the mobile phone terminal 5.

  When GPS positioning data is attached as shown in FIGS. 3A and 3B (Yes in step s5), the current location information is the receivable area shown in the broadcast station list table 31 in FIG. For example, when it is included in “Zone A01” (Yes in step s5-1), the name of the corresponding broadcasting station and information such as the reception channel registered in advance are received as reception setting data to the mobile phone terminal 5. A reply is made (step s5-11).

  If it is not included in any receivable area (No in step s5-1), “not applicable” is returned as reception setting data (step s5-12).

  The cellular phone terminal 5 notifies the control processing unit 55 of the reception setting data received by the communication processing unit 52. The control processing unit 55 displays on the I / O unit 54 the names of broadcast stations that can be received by a predetermined procedure related to the one-segment broadcast reception application (step s7). Then, the one-seg broadcasting station is selected and received according to a predetermined input setting such as selection of a broadcasting station when a plurality of broadcasting stations are displayed as candidates from the user who has read it (step s8).

  Next, the operation when the position information is not included in the information received by the distribution server 3 will be described. In this case, the RSID of the radio relay station (RF head) of the connected relay device 2 shown in FIG. 3C is the RF head 21 paired with the area one-segment transmitter 22 according to the embodiment of the present invention. is there. In the relay apparatus 2 in which it is installed, a spot service area one-segment transmitter 22 having a smaller cover area than a general one-segment broadcasting station is installed.

  The cover area where the RF head 21 can make a call and the cover area where the radio wave (broadcast) transmitted by the area one-segment transmitter 22 can be received are aligned as described above. In the area one seg transmitter 22 installed together with such an RF head 21, the corresponding one seg broadcasting station name and installation RSID are registered in advance and stored and stored on the table as shown in FIGS. Has been.

  If there is no GPS data in the position information column of the information received by the distribution server 3 (No in step s5), the distribution server 3 reads the identification information of the connection destination of the mobile phone terminal 5 (step s5-2), If it matches the installed RSID in FIG. 4 (Yes in step s6) (here, “BST9746”, which corresponds to FIG. 4 (e)), the name of the installed broadcasting station “D3456” and its The reception channel information of the broadcasting station and the like are returned as reception setting data to the mobile phone terminal 5 (step s61).

  Based on the reply result, the mobile phone terminal 5 displays the name of the receivable broadcasting station, etc., on the I / O unit 54 (step s7). A one-segment broadcast selected according to a predetermined input setting such as selection of a broadcast station when displayed is received (step s8).

  When the connection destination does not match the installation RSID described in the table (No in step s6), “not applicable” is set as reception setting data (step s5-12).

  As described above, in the one-segment broadcasting system that guides the reception channel of the one-segment broadcasting using the GPS position information, the area one-segment broadcasting can be accurately provided even in a closed area where GPS positioning data cannot be received. .

  In particular, in tunnels, general one-seg broadcasting and mobile phone calls can no longer be received. However, by providing a relay device in the tunnel that uses both directional antennas and covers both areas, It is possible to provide a continuous telephone call and a service capable of continuously receiving general one-segment broadcasting. At this time, by making the transmission frequency of the area one seg broadcasting in the tunnel, that is, the transmission frequency of the one seg transmitter 22 different from the frequency (channel) of the general one seg broadcasting outside the tunnel, interference is avoided, emergency broadcasting, It is also possible to notify a traffic guide broadcast.

Next, further effects of the present embodiment will be described.
In the present embodiment, not only the receivable broadcast stations are notified as described above, but these area one-segment broadcast stations can be automatically received. For example, in an indoor exhibition hall, area one-segment broadcasting for each exhibit can be used to explain each exhibit. That is, the area one seg broadcasting station provided for each exhibit is installed so as not to overlap the cover areas.

  For example, FIGS. 4E and 4F show that the relay device 2 is separated from the A1 area (A1 Block) and the A2 area (A2 Block) in the # 1 building (# 1BUILDING) of the exhibition hall called DSHOW. Installed at the place, and repeatedly sent explanations about the exhibits at regular intervals. When there is only one receivable broadcast station candidate indicated in the reception setting data as an operation option of the one-segment broadcasting of the mobile phone terminal 5, the control processing unit 55 receives the broadcast reception signal of the candidate station. By performing control to demodulate and output from the display or speaker of the I / O unit 54, the explanation broadcast can be automatically received and output.

FIG. 6 is a flowchart showing a detailed procedure of step s8 of FIG.
That is, in FIG. 6, the control processing unit 55 of the mobile phone terminal 5 interprets the reception setting data received from the communication processing unit 52, and there is only one broadcast station (candidate station) of the area one-segment transmitter 22 that can be received. (Step s81 is Yes), the reception channel setting data of the reception setting data of the candidate station is input to the broadcast receiving unit 51, and the broadcast program signal demodulated by the broadcast receiving unit 51 is displayed on the display of the I / O unit 54. Output from the speaker (step s83).

  If there are a plurality of candidate stations, not automatic reception (No in step s81), the candidate station list is displayed on the display and a selection input is waited (step s84). Then, the radio wave of the selected broadcasting station is received and demodulated and output (step s85).

  Further, as another automatic reception method that is possible even when there are a plurality of candidate stations, a forced reception mode is provided for a specific area one-segment broadcasting station. For example, when sending a reply from the distribution server 3 to the mobile phone terminal, there is a method of adding to the reception setting data forcible reception information that is immediately received preferentially for the reception channel. For example, a “+” sign indicating forced reception is added after the broadcast station name. Then, the control processing unit 55 interprets the reception setting data and checks whether or not “+” is present (Yes in step s82), receives and demodulates the marked broadcast station (step s86). ).

FIG. 7 is a flowchart showing a detailed procedure of step s8 of FIG. 5 which is an application of FIG.
In this case, by replacing the steps s81 and s82 in FIG. 6, the compatibility in the case where there are a plurality of one-segment broadcasting stations is improved.

  As a modification, for the specific reception channel transmitted from the distribution server 3 in place of the mark for the entire system, an operation rule for immediately outputting the channel information when the channel information is received is provided. There is also a method for forced reception by setting.

  In the case of the above description, when reception of the area one-segment broadcasting station is started, the reception response report is transmitted from the mobile phone terminal 5 to the distribution server, and the distribution server that has received the reception response report transmits the reception setting data. To stop. Further, the cellular phone terminal 5 cancels the procedure for receiving the reception setting data from the distribution server 3.

  As a further application of the present embodiment, there is an emergency forced reception mode that enables emergency broadcast reception. In the emergency compulsory reception mode, reception setting data is continuously transmitted and received without releasing transmission / reception of reception setting data even after reception of area one-segment broadcasting is started. If there is an area one seg that has started emergency broadcasting during reception, the control processing unit 55 receives the reception data with the forced reception mark or the information on the specific channel described above. Switch from the area one seg broadcasting station to the target station for forced reception.

  This emergency forced reception mode is effective as a forced interrupt broadcast at the exhibition hall, and is effective for lost child guidance, fire notification, and the like. It is also effective for emergency broadcasts and traffic information guidance in tunnels. In other words, an emergency broadcast system (not shown) notifies the distribution server 3 that an emergency has occurred, and the area one seg broadcasting station attached to the relay device 2 starts emergency broadcast, thereby enabling forced interrupt broadcast.

  In this method, even if multiple area 1Seg broadcasts are broadcast within the same closed area, if the channel is set by this mobile phone and 1Seg broadcasts are received, forced interrupt broadcasts that cannot be received by conventional 1Seg broadcast receivers Can be received.

  As described above, the one-segment broadcasting system of the present invention can acquire and receive channel information of a one-segment broadcasting station even in a closed area where external radio waves do not reach.
