Details will be described together with the description of the operation. The other information indicates the same content as the information of the same name recorded in the provider information management database 113.

  Next, the operation of the embodiment of the present invention will be described with reference to FIGS. In this description, registration information, which is information relating to broadcast distribution from the content provider 100, is registered in the management center 110, the registered information is notified from the management center 110 to the portable terminal 120 as provider information, and based on the notified information. The operation of the mobile terminal 120 is shown.

  FIG. 5 is a flowchart illustrating an example of provider search operation of the terminal 120 according to the embodiment. FIG. 5 shows a processing operation for searching for a reproducible provider (content) using the provider information acquired by the form terminal 120.

The control unit 204 acquires the position information (latitude and longitude) of the mobile terminal 100 from the position specifying unit 201 (step S411).
The control unit 204 compares all the provider information, which is information related to broadcast distribution registered in the provider information database 203, with the location information of the mobile terminal 120, and ends the processing if the comparison of all providers has been completed ( Step S412).
If the provider comparison is not completed (No in S412), the control unit 204 acquires provider information of the provider to be compared next from the provider information database 203 (Step S413).
The control unit 204 calculates the distance between the two points from the registered provider location information and the current location information of the mobile terminal 100 (step S414).
The control unit 204 checks whether it is within the reception range from the calculated distance and the reception range registered in the provider information database 203 (step S415).
If it is within the reception range (Yes in S405), the reproducible flag in the provider information database 203 is set to “available”, and the process returns to S402 (step S416).
If it is outside the reception range (No in S405), the playable flag is set to “impossible” and the process returns to S402 (step S417).

  Next, a processing operation in which the form terminal 120 reproduces a reproducible provider (content) using the reproducible flag will be described.

FIG. 6 is a flowchart showing the content reproduction operation of the terminal 120 according to the embodiment.
The control unit 204 outputs, from the output unit 206, the provider name for which the reproducible flag is set to “possible” among the information registered in the provider information database 203 (step S421). A summary of the content may be displayed together with the provider name.
Based on the information output to the output unit 206 by the user, a desired content provider is selected by a cursor operation or key operation of the input unit 205. At this time, the control unit 402 identifies the selected provider (step S422).
The control unit 204 acquires the transmission frequency (channel) of the provider identified from the provider information database 203 as the reception frequency (channel) (step S423).
The control unit 204 adjusts the broadcast receiving unit 202 to the reception frequency (step S424).
The control unit 204 acquires content from the broadcast receiving unit 202 (step S425). Note that when the direct broadcast receiving unit 202 has a function capable of reproducing the content without using the control unit 402, the content may be reproduced without using the control unit 202.
After that, the control unit 204 ends the process when the user's reception end (stop process) or the like is identified (step S426).

  If necessary, reproducible content (a content provider whose reproducible flag is “possible”) may be switched so as to switch the television channel. In this case, when the switching operation from the user is identified, the provider information database 203 is referred to identify the content for which another reproducible flag is possible, and the processing operation after S423 may be performed.

  Further, when the form terminal has a plurality of broadcast receiving units, the broadcast receiving unit may be operated so as to be switched together with the broadcast frequency. In addition, when there are a plurality of contents identified as reproducible, the broadcast receiving unit may be controlled to selectively reproduce the contents to be reproduced using the transmission frequencies of the plurality of identified contents. By operating in this way, for example, it is possible to seamlessly switch between broadcast distribution (broadcasting) transmitted in a limited area of both digital television broadcasting and FM broadcasting.

  Also, using the broadcast time included in the information related to broadcast distribution, the mobile terminal 120 compares the broadcast time recorded in the provider information with the current time acquired from RTC, GPS, etc., and within the broadcast time. For example, a reproducible flag may be set. In this way, it is possible to avoid selecting the content during the time when the content provider is stopped (stopped).

  In other words, the position information of the current position can be acquired, and the portable terminal 120 capable of reproducing the content broadcasted (broadcasted) via the radio wave, and the radio wave from the predetermined position. Information related to broadcast distribution including at least position information, a reception range, and a transmission frequency (channel) for transmitting radio waves from the content provider 100 using the content provider 100 that performs broadcast distribution (broadcasting) using a predetermined server Is registered in the management center 110 and the mobile terminal 120 is notified of information related to broadcast distribution, so that the mobile terminal 120 can reproduce content that can be played back using the information related to broadcast distribution notified from the management center 110. Can be identified and played backThat is, it is possible to realize a cell broadcast service that does not incur a pseudo communication cost.

  At this time, the portable terminal 120 may be operated so as to acquire position information of the current position, compare it with position information included in the notified broadcast distribution information, and identify reproducible content. As an example, the mobile terminal 120 calculates the distance of two points from the position information of the current position and the position information included in the notified broadcast distribution information, and uses the calculated distance to receive the notified reception. It is only necessary to determine whether or not the content is within the range and identify the reproducible content.

  In addition, when there are a plurality of contents identified as reproducible, the mobile terminal 120 can appropriately reproduce reproducible contents by selectively switching the transmission frequency between the identified contents. At this time, if the broadcast time included in the information related to broadcast distribution is used, it is possible to identify content that can be reproduced even better.

  In addition, when the mobile terminal 120 includes a plurality of broadcast receiving units, the content may be played back using the broadcast receiving unit suitable for the content identified as reproducible in a timely manner.

  Registration and notification of information related to broadcast distribution by the management center 110 can be performed by using e-mail, so that the provider side and the user side do not have to disclose each other's e-mail address, thereby protecting personal information. It becomes a tailwind for the introduction and use of wireless broadcast distribution.

  As described above, according to the present embodiment, since radio waves are used for content transmission, it is possible to eliminate communication costs.

  In addition, the capital investment of the content provider can be minimized. In particular, when using FM radio waves, a transmitter of a mini FM station (community FM station) can be used, and equipment can be procured at low cost. In addition, in the case of a radio station using weak radio waves, the application cost can be reduced to zero because an application for opening a station under the Radio Law is unnecessary.

  Next, a second embodiment of the present invention will be described with reference to FIG.

  In the second embodiment, the content provider 100 of the first embodiment is realized using a portable terminal having a broadcast transmitter. In addition, the same number is attached | subjected to the same structure and description is abbreviate | omitted. Further, the operation of each unit may be performed in the same manner as in the first embodiment, and thus description thereof is omitted.

That is, the portable terminal 500 notifies the management center 110 of registration information, which is information related to broadcast distribution, and broadcasts the stored content 211 from a predetermined position using radio waves. The broadcast transmitter 212 may be one that is externally connected to the portable terminal 500. Moreover, you may acquire a content via a communication line. Examples of the portable terminal 500 include a mobile phone equipped with an FM transmitter, a PHS, and a mobile information processing apparatus. Moreover, the terminal mounted on the vehicle etc. are mentioned. Further, it may be a wireless terminal (device) that locally transmits a television broadcast.

  In the case of the first embodiment, the content provider needs to investigate and register the provider's location information using, for example, map software of a personal computer. Therefore, in the present embodiment, the position specifying unit 501 built in the portable terminal 500 is used to acquire position information of a position (point) where broadcast distribution is performed as a content provider, and is stored in the management server 110 as part of registration information. Notice.

  In addition, since the broadcast transmitter mounted on the portable terminal is used, the capital investment required for each predetermined position for broadcast distribution (broadcasting) becomes unnecessary.

  Further, if a communication function (not shown) or a mail transmission function (not shown) of the portable terminal is used, the registration information can be easily notified to the management center 110.

  Thus, according to the present embodiment, a portable content provider can be operated with good convenience. For example, it is suitable for a content provider operated only at a limited place on a limited date and time.

  As described above, according to the present invention, it is possible to provide a wireless broadcast distribution system that realizes broadcast broadcasting that provides information to a limited area.

  In addition, the specific configuration of the present invention is not limited to the above-described embodiment, and changes within a range not departing from the gist of the present invention are included in the present invention.

  According to the present invention, it can be used in a wireless broadcast system that realizes pseudo cell broadcast without charging costs.
