  • step S360 it is determined whether or not the supplied information is information for receiving a present (information for permitting a present). If it is determined that the supplied information is information for permitting the present, the process proceeds to step S355, and the subsequent processing is performed. Since the processing after step S355 has already been described, the description thereof will be omitted, but in the case of a schedule related to a present, a different processing is included.
  • step S353 the information for determining whether or not the time is specified is performed by referring to a schedule that has already been written as an undetermined schedule. In other words, the undetermined schedule has already been created as a schedule including the information as shown in FIG. 22.
  • step S 354 if the written time is compared with the current time and it is determined that the written time is earlier than the current time, This indicates that the written time has elapsed. In other words, it is determined that the time specified as the time for providing the present has passed.
  • step S356 the process proceeds to step S356, and the time that can be transmitted at the time closest to the specified time is set at that time rather than set as the transmission time. It is better to set the transmission time as soon as possible as the transmission time.
  • the "transmission time” in the schedule is set, and when the set time is written, the "transmission status” information also indicates “not transmitted” from the information indicating "unconfirmed”
  • the number of reservations written in the undetermined part 3 2 3 of the destination table 3 2 1 is subtracted by 1, and the number of reservations corresponding to the set time of the determined part 3 2 3 Is added by 1.
  • step S360 determines whether the information from the user receiving the present is information not to receive the present.
  • step S3661 the schedule that has been determined to be undetermined and corresponding to the content for which the present has been rejected is discarded.
  • This discarding process includes a process in which the number of reservations in the undetermined portion 3 23 of the destination reservation table 32 1 is decremented by one.
  • the schedule created in this way is provided, for example, when STB 11 inquires at a predetermined time interval whether or not a new schedule has been created for itself. Is done. The STB 11 requests transmission of content data based on the provided schedule, but the request is issued at a time after the time when the schedule was provided.
  • the STB 11 has a storage unit 85 ( Figure 3) having a finite capacity, and stores the received content data in its storage unit 85. At this point, even if the storage unit 85 has a capacity to store the data amount of the content data to be transmitted based on the schedule, the time until the actual transmission of the content data is requested. In addition, another content data may have been received and stored, so that the storage unit 85 may have run out of space.
  • the storage unit 85 does not have the capacity to store the content data. As a result, things can happen if you can't remember. Further, in the case where the data cannot be memorized, or when the error occurs on the STB 11 side, for example, the service provider 2 needs to perform a process of retransmitting the data.
  • the processing related to the transmission of the content data performed on the service provider 2 side in consideration of the above will be described with reference to the flowchart of FIG. 36.
  • the flowchart shown in FIG. 7 is configured such that the processing of step S385 and step S386 is added. That is, the processing of steps S3881 to S384 of the flowchart shown in FIG. 36 and the processing of steps S388 to S391 of the flowchart shown in FIG. Reference
  • the processing in steps S231 to S234 and the processing in steps S235 to S239 are the same. Here, the description of the same processing has already been described, and thus will be omitted.
  • the STB 11 transmits information on the remaining capacity of its own storage unit 85 to the service provider 2 when issuing a request for transmission of content data.
  • the service provider 2 compares the remaining capacity of the received storage unit 85 with the data size of the content data requested to be transmitted, and determines that the remaining capacity of the received storage unit is equal to the transmission request. Only when it is determined that the data size is larger than the content data, the process proceeds to step S387, and the subsequent process, that is, the process related to the transmission of the content data is executed.
  • the STB 11 when the STB 11 issues a request for transmission of content data, the STB 11 transmits the remaining capacity of its own storage unit 85 and the data size of the content data requested to be transmitted.
  • the information can be obtained by being included in the received schedule information), and the storage capacity for storing the content data remains in the storage unit 85.
  • the service provider 2 receives either the information indicating that the content data can be received or the information indicating that the content data cannot be received. Using such information, the service provider 2 may perform the process of step S385. In any case, the service provider 2 does not execute the processing after step S387 unless the STB 11 determines that the received content data can be stored. Therefore, it is possible to prevent the inconvenience that occurs when the transmitted content data cannot be stored on the STB 11 side.
  • the "send time" of the schedule needs to be rewritten (changed). This change may be made so that the transmission is executed again after a predetermined time elapses, for example, set one hour after the time at which the current time is written. In this case, the contents of the transmission schedule table 3 21 are also rewritten, and the reservation number of the newly set time portion is changed to a value obtained by adding one.
  • the rewritten schedule is provided to the STB 11 again, and the STB 11 executes the processing based on the provided schedule, so that the content data is obtained. Is transmitted and received.
  • a request for transmission of the content data may be issued again when the STB 11 is in a state capable of storing.
  • the service provider 2 keeps the "send status" of the corresponding schedule as unsent, and does not do anything when the corresponding schedule is deleted. Such a process may be performed.
  • the series of processes described above can be executed by hardware having respective functions, but can also be executed by software.
  • various functions are implemented by installing a computer in which the programs constituting the software are incorporated in dedicated hardware, or by installing various programs. It is installed from a recording medium into a executable personal computer, for example.

Abstract

L'invention concerne un système de traitement d'informations, un appareil de traitement d'informations, un procédé de traitement d'informations et un programme de traitement d'informations permettant d'acheter des contenus de manière plus commode. Au cours de la présentation des données de contenu, un côté de présentation transmet des premières informations permettant d'identifier le côté de présentation, des deuxièmes informations permettant d'identifier un côté présenté, et des troisièmes informations permettant de choisir les données de contenu à présenter. Lorsque de telles informations sont transmises, un e-mail demandant si la présentation est acceptée ou non est envoyé, en fonction des deuxièmes informations, au côté qui peut potentiellement recevoir la présentation. Le traitement de la présentation est exécuté à la seule condition qu'une réponse positive soit donnée en réponse à l'e-mail. Cette invention peut être utilisée dans un serveur afin d'exécuter des traitements relatifs aux données de contenu.
