Next, the operation of the above embodiment will be described.
First, the operation when a guest room user of this hotel receives printing of authentication information by the vending machine 3 in order to view paid channel broadcasting will be described.

  FIG. 5 shows the contents of processing by the control unit 11 in the vending machine 3, and at the beginning of the processing, it is determined whether or not the specified fee has been received depending on whether or not the banknote receiving unit 14 has inserted cash. Is repeated to wait for the receipt (step A01).

  If it is determined in step A01 that the prescribed fee has been received, the front computer 2 is notified (step A02).

  In the front computer 2 that has received this notification, the control unit 21 has confirmed that authentication information based on random numerical values of, for example, six mobile phones is not duplicated with other authentication information that has been issued in the past by using only one unit by a predetermined algorithm. The above is generated and sent to the vending machine 3 (step A03).

  Upon receiving this authentication information, the control unit 11 of the vending machine 3 reads the current date and time information from the timer 17 and prints out the authentication information and the date and time when it was issued by the printer 13. Issue (step A04).

  Thereafter, the control unit 11 of the vending machine 3 ends the series of processes as described above, and returns to the process from step A01 to prepare for the next user.

  Next, the operation when the guest room user of this hotel who has received authentication information for a fee as described above returns to his / her room and views a pay program will be described.

  6 and 7 mainly show the contents of processing for viewing a pay program by the control unit 42 of the guest room terminal 5, and at the beginning of the process, the pay program is broadcast by key operation on the remote control pad 7. FIG. By repeatedly determining whether or not a certain channel has been designated (step B01), or whether or not the checkout time has been reached by the time counting by the timer 49 (step B02), the system waits for these states. .

  If it is determined in step B02 that the check-out time has come, the flag register F indicating that the pay program is viewable and held in the control unit 42 at that time is cleared to “0”. In addition, an initial value “0” is also given to the counter n for counting the number of times the authentication information is illegally held, which is also held inside the control unit 42 (step B04), and the above step B01 is again performed. Return to processing from.

  If it is determined in step B01 that the broadcast channel of the pay program has been designated, the control unit 31 next determines whether or not the flag register F at that time is “0” indicating that the charging process has not been confirmed. Is determined (step B05).

  If it is determined that the flag register F is “0”, a screen including a guide message for confirming that the designated channel is a pay program is displayed on the television receiver 6 (step B06), waiting for any key operation corresponding to the screen to be performed from the remote control pad 7 (step B07).

  FIG. 8A exemplifies a guide message displayed on the screen of the television receiver 6 at this time. The remote control pad 7 is used to confirm that the designated channel is a pay program. When the confirmation key is changed to another channel, the user is prompted to operate the key of the desired channel number.

  If any key operation is performed here, it is determined whether or not it has been confirmed that the operation shifts to viewing of a pay program channel depending on whether or not the operated key is the “confirm” key (step B08). ).

  If it is determined that a key other than the “confirm” key has been operated, it is assumed that a key operation for changing to another channel has been performed, and the corresponding channel change processing is performed (step B09). The process returns to the above-described step B01 to prepare for the designation of the pay broadcast channel again.

  If it is determined in step B08 that the “confirm” key has been operated, the process proceeds to a state for inputting authentication information printed and issued by the vending machine 3 (step B10).

  FIG. 8B illustrates an input state of the authentication information displayed on the screen of the television receiver 6. The guide message is displayed so that the printed cipher is input and the number of input digits is displayed. A cursor indicating the status of is displayed.

  When authentication information of a predetermined number of digits is input by the numeric keypad of the remote control pad 7 in accordance with this display, the control unit 42 modulates the input authentication information by the high frequency modem 46 to switch the demultiplexer 41 and the local television distribution network 4. To the front computer 2 (step B11).

  When the front computer 2 receives the authentication information from the guest room terminal 5 (step B12), the authentication information received by the control unit 21 is issued on the same date and compared with the authentication information that has not been verified yet. Then, whether the authentication information is correct or not is determined based on whether or not there is the same authentication information (step B13).

  Here, when the received authentication information is correct authentication information, the control unit 21 of the front computer 2 transmits viewable information permitting viewing of the pay program to the guest room terminal 5 via the local television distribution network 4. (Step B14).

  When this is received by the control unit 42 via the local television distribution network 4, the demultiplexer 41, and the high frequency modem 46 on the side of the guest room terminal 5 (step B 15), the control unit 42 receives the user of the guest room terminal 5. Is set to "1" in the flag register F (step B16), and as specified, as shown in FIG. 8C. (Step B 17), and waits for a key operation for changing the channel or turning off the power of the television receiver 6 to be performed on the remote control pad 7 (step B 17). In step B18), when these key operations are performed, the process returns to step B01.

  If the flag register F is “1” instead of “0” in step B05, the billing process has already been confirmed with the front computer 2; The process of B16 is omitted, and the process directly proceeds to step B17 to shift to viewing of the pay program channel.

  When the control unit 21 of the front computer 2 determines in step B13 that the authentication information received from the cabin terminal 5 is not correct authentication information, that is, authentication information that has not been generated, and generation If it is determined that the authentication information has been authenticated because the authentication information having the same contents has already been sent from another guest room terminal 5, on-premise TV distribution that prohibits viewing of the pay program is permitted. It transmits to the said guest room terminal 5 via the network 4 (step B19).

  When this is received by the control unit 42 via the local television distribution network 4, the duplexer 41, and the high frequency modem 46 at the guest room terminal 5 side (step B20), the control unit 42 sets the count value of the counter n to “+1”. After the update setting (step B21), it is determined whether or not the count value of the updated counter n has reached a predetermined number of times, for example, “4” (step B22).

  Here, if the count value of the counter n has not reached “4”, the fact that the content of the inputted authentication information is incorrect is displayed once on the screen of the television receiver 6 by a guide message ( Step B23), and again proceeds to the process of inputting the authentication information from Step B10.

  If it is determined in step B22 that the count value of the counter n has reached “4”, the user can select the channel of the pay program without receiving the official authentication information printing by the vending machine 3. When it is determined that the user intends to view the program, the operation of a part of the guest room terminal 5 is automatically automatically prohibited, specifically, the viewing of all pay program channels including the pay program is temporarily prohibited. At the same time (step B24), a message indicating that it is necessary to contact the front of the hotel is displayed on the screen of the television receiver 6 by a guide message (step B25), and then the process returns to step B01 again.

  However, at the front of the hotel, when a guest room is informed that viewing of a pay program is prohibited, the vending machine 3 warns the user to obtain pay authentication information and uses the keyboard at the front computer 2. Alternatively, the viewing prohibition state of the pay program of the guest room terminal 5 can be canceled and set by manual operation of the mouse.

  In this way, within the range of regular use environment, the management cost required for the issuance and collection of billing information media such as prepaid cards is sufficiently reduced without human intervention like hotel front work. By making it easy for many people to use it, it is possible to increase the profit and collect the profit reliably.

  In addition, in the above embodiment, the vending machine 3 does not simply display the issued authentication information on the display unit 22, but memorizes the authentication information to the user by printing it out with a simple printer mechanism or the like. This makes it possible to avoid unnecessary troubles in system operation such as user's memory mistakes, without forcing the burden of having them refrain from taking notes or taking notes.

  In the above-described embodiment, the local television distribution network 4 is used to perform bidirectional communication between the plurality of guest room terminals 5, 5,... And the front computer 2, but instead, A LAN connection system for performing packet communication of digital content data may be constructed.

  In particular, when transmitting / receiving large-capacity digital content data (moving image data) as in a video-on-demand service, it is preferable to use a connection system using a LAN because operational technology has already been established. Furthermore, it is conceivable to use a television distribution network and a LAN connection system in combination.

  In addition, in the above embodiment, authentication information generated by a predetermined algorithm may or may not be encrypted. Furthermore, in the above-described embodiment, the generation of authentication information has been described as being performed by the front computer 2, but the present invention is not limited to this, and the vending machine 3 generates the authentication information, and the generated authentication information is stored in the front computer. Notification to 2 can be considered similarly.

  In the above embodiment, the authentication information is input by key operation on the remote control pad 7 attached to the cabin terminal 5, so that no special input device is required and channel selection is performed. Since the encryption information can be entered with the same operational feeling as the above, the user can easily use it while greatly reducing the equipment cost.

  Further, in the above embodiment, illegal authentication information input is counted, and viewing of pay broadcasts is temporarily prohibited when the count value reaches a predetermined number. Therefore, by restricting the input of unauthorized authentication information, it is possible to surely increase profits.

  In addition, although the said embodiment demonstrated the case where it applied to the premises television delivery network system of a hotel, this invention is not restricted to this, Television broadcasting is carried out with the television receiver installed in every hospital bed, such as a hospital. Of course, the present invention is also applicable to a local television distribution network system for viewing.

  In addition, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  Further, the above embodiments include inventions at various stages, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent elements. For example, even if some constituent elements are deleted from all the constituent elements shown in the embodiment, at least one of the problems described in the column of the problem to be solved by the invention can be solved, and described in the column of the effect of the invention.
