Processing for receiving a program is also performed. Further, the CPU 209 also performs processing for writing various information (exhibit list information, etc., which will be described later) into the reception card 5.
[0025]
FIG. 2 is an explanatory diagram showing an overview of the in-facility exhibit information providing system. In order to prevent viewing other than the specific CH (channel) in the facility 1 by the portable receiving terminal 2, the viewing radio wave blocking device 11 executes this to maintain the environment in the facility 1. Specifically, the facility 1 is shielded by a radio wave blocking material, and a broadcast wave is received by an antenna provided outside the facility 1, and a received broadcast wave (limited reception CH) is received by a re-transmission device installed in the facility 1. Are retransmitted at the same frequency.
[0026]
When the user (facility user) enters the facility, the portable receiving terminal 2 or the receiving card 5 may be brought or borrowed from the facility. When bringing the reception card 5, when entering the facility, the reception card 5 is inserted into a dedicated information writing device, and key information and time limit information are recorded. The user can load the receiving card 5 into the portable receiving terminal 2 and view the limited CH. Note that if the deadline information is set to several days (for example, two days), the broadcast receiver at home outside the facility can receive the limited CH for several days.
[0027]
In addition, when entering the hall, a microdrive card 4 in which information (video / audio / text information) related to the exhibit is stored is lent. Further, the user can bring his own memory card 3 into the hall, load the memory card 3 into the portable receiving terminal 2, and transfer information in the microdrive card 4 to the memory card 3.
[0028]
First, the user selects a channel that guides the entire facility at the portable receiving terminal 2 and views it to know the description of the facility or device, precautions, etc. (Reference number group) can be acquired. The exhibit list can also be obtained from the microdrive card 4. Further, the user selects an information providing mode related to the exhibit on the screen of the portable receiving terminal 2. This mode remains in effect until it is changed by the user. Modes that can be set include “area CH automatic reception selection for each theme of exhibit”, “forced viewing selection of guide”, “guide selection of audio only for exhibition”, “guide selection of text information only”, “Guide selection with mixed media including video”. In the portable receiving terminal 2 lent from the facility, software is incorporated so that these settings can be made. However, in the portable receiving terminal 2 brought by the user, these settings may not be possible.
[0029]
When the user enters a certain exhibition theme area, the user detection sensor 12 detects the user by, for example, an ultrasonic detection method and gives the user's entry to the forced CH transition signal transmitter 13. For example, if the forced CH transition signal transmitter 13 is configured to correspond to a television remote control transmitter, it outputs an infrared pulse remote control signal. The remote control light receiving unit 232 of the receiving terminal 2 receives the remote control signal, converts it into an electrical signal, and gives it to the CPU 209. The CPU 209 recognizes the command (CH transition command) that the remote control signal means and controls the tuner 230, and the received video of the selected CH is displayed on the screen of the receiving terminal 2. If the user does not want such automatic CH transition, “NO” may be selected in “Area CH automatic reception setting for each theme of exhibit”. It is also possible to give a CH transition command to the receiving terminal 2 using the communication block 216.
[0030]
When the user approaches the exhibit on which the management information transmitting device 14 is installed and the user operates, for example, an item part “request for exhibit information” displayed on the menu screen of the portable receiving terminal 2, the request signal is sent to the communication block 216. To the management information transmitting device 14. The reception sensitivity of the management information transmission device 14 is set so that communication is possible when the management information transmission device 14 and the communication block 216 are closer to each other by a predetermined distance or more, and a request signal is always generated on the portable reception terminal 2 side. When the user approaches the exhibit, a request signal is automatically given to the management information transmitting device 14 without a user operation. Such automatic processing is performed when the “forced guide viewing selection” setting is “YES”. Upon receiving the request signal, the management information transmitting device 14 returns a signal indicating the exhibit management number. This signal is received by the communication block 16 of the portable receiving terminal 2 (in the case of infrared signal transmission, the remote control light receiving unit 232), and the CPU 209 receives the content corresponding to the exhibit from the microdrive card 4 based on the exhibit management number ( Read the detailed information of the exhibit). This content is provided to the user by the LCD panel 202 or the earphone 203. When the user makes an intention to save the content viewed at this time (for example, by operating the “Save” button displayed on the screen), the image quality of the content stored in the microdrive card 4 is determined. A compressed file having a small file size with a small drop is stored in the memory card 3 inserted in the slot 201. Further, when such information is read out, the exhibit management number is recorded on the receiving card 5 as a selected exhibit list. In the portable receiving terminal 2 lent from the facility, software is incorporated so that a series of these processes can be performed. However, the portable receiving terminal 2 brought by the user may not be able to perform these processes.
[0031]
Note that reading of information from the microdrive card 4 is performed according to a mode set by the user (video / audio, audio only, characters only). Further, when the management information transmission device 14 receives a request signal by a user operation, the number of accesses is counted up and stored in the aggregation server 15 connected to the management information transmission device 14 for the purpose of counting the number of accesses to the exhibit. I try to do it.
[0032]
When leaving the facility 1, the loaned items such as the microdrive card 4 are returned to the facility. When key information and time limit information are written in the received reception card 5 that the user brings, as shown in FIG. 3, the user can, for example, a card slot of the fixed receiver 21 or the mobile receiver 22 that can receive terrestrial digital broadcast waves. When the receiving card 5 is loaded, the limited CH can be selected and received for a predetermined period even outside the facility. Further, when the fixed receiver 21 and the mobile receiver 22 are equipped with a modem or the like and can perform two-way communication (if the portable reception terminal 2 is capable of two-way communication, the portable reception terminal 2 is also included). For example, the selected exhibit list stored in the reception card 5 is read out by dial-up connection to the broadcasting station 31 and displayed on the screen using a browser (currently a BML browser). When a desired exhibit item is selected on this screen, the broadcast station is notified via a communication line, and both video / audio and explanatory text data (content) related to the requested exhibit are received from the program content storage server in the broadcast station. Distributed using communication. The distributed content includes information about contents that could not be viewed within the facility.
[0033]
If URL information is included in this information, a predetermined homepage can be accessed via the Internet as shown in FIG. 4, and if channel information is included, related product purchase CH or the like in broadcast reception. Can be received. When the user wishes to purchase related products by receiving the related product purchase CH, if the user performs an operation according to the menu from the purchase CH, the broadcast station 31 is notified via a communication line, and sales information in the broadcast station 31 is received. The information is stored in the management server, notified to a related product sales company 41 via a communication line, and a sales contract is concluded. Thereafter, the product arrives under the user according to the procedure found in normal mail order, and the user pays the price.
[0034]
Further, when it is desired to edit and save information related to exhibits for the purpose of creating reports and saving materials, the memory card 3 may be used. If editing software is installed in a personal computer or PDA equipped with a reader for the memory card 3, editing with a high degree of freedom, saving in various formats and media, and the like can be performed. Even program content can be edited and saved with some restrictions.
[0035]
