Content delivery system, delivery server, receiving terminal, and content delivery method

A content delivery method for transmitting picture content transmitted from a transmitting terminal to a receiving terminal via a delivery server, the method comprising:

• when the transmitting terminal accesses the delivery server and inputs sender's information and a member ID identifying a receiving terminal as a destination, to the delivery server,
• tentatively registering the receiving terminal's member ID by the delivery server and notifying the tentatively registered receiving terminal that tentative member registration of a sender has been made based on the member ID;
• in a case where the tentative member registration has been accepted by the receiving terminal, registering the tentatively registered member information by the delivery server;
• storing a picture contents transmitted from transmitting terminals by the delivery server;
• and
• in a case where transmission of a picture content destined to a receiving terminal's member ID is requested from the registered receiving terminal, transmitting by the delivery server the picture content to the receiving terminal.

A transmitting terminal in a content delivery system comprising the transmitting terminal, a receiving terminal, and a delivery server which are connected via a network and configured to transmit picture content from the transmitting terminal to the receiving terminal via the delivery server,

• the transmitting terminal comprising a transceiver configured to access the delivery server which comprises:
• a database for registering device IDs each identifying each receiving terminal and member IDs each configured to be assigned to a plurality of devices by a user in such a manner that the device IDs and the member IDs are associated with each other;
• a content storage for storing picture contents transmitted from transmitting terminals,
• wherein the transceiver transmits, to the delivery server, a member ID of a receiving terminal which is tentatively registered by the delivery server in the database and which is for notifying the tentatively registered receiving terminal that tentative member registration of a sender has been made,
• in a case where the tentative member registration has been accepted by the receiving terminal, the transceiver receives from the delivery server a notification that the delivery server has registered the tentatively registered member information, and
• the transceiver transmits to the delivery server picture content to be stored in the content storage by the delivery server and, in response to a request from a receiving terminal, to be transmitted to the receiving terminal by the delivery server.

A content delivery system comprising a transmitting terminal, a receiving terminal, and a delivery server which are connected via a network and configured to transmit picture content from the transmitting terminal to the receiving terminal via the delivery server,

• the delivery server comprising:
• a storage configured to store a database for registering information identifying each receiving terminal and picture contents transmitted from transmitting terminals;
• and
• a transceiver configured to transmit and receive information to/from the receiving terminal and the transmitting terminal, and
• the transmitting terminal includes a transmitting portion configured to transmit picture content to the deliver server and information identifying a receiving terminal which receives the picture content,
• wherein the deliver server notifies, based on the information identifying the receiving terminal which receives the picture content transmitted from the transmitting terminal, the receiving terminal of an inquiry as to whether or not the receiving terminal receives the picture content transmitted from the transmitting terminal, in case where the receiving terminal has accepted reception of the picture content, the delivery server registers the information identifying the receiving terminal which receives the picture content in the database and allows the receiving terminal to receive the picture content stored in the storage, and in response to a request from the receiving terminal, the delivery server transmits the picture content to the receiving terminal.

A transmitting terminal for transmitting picture content to a receiving terminal via a delivery server,

• wherein the delivery server includes:
• a storage configured to store a database for registering information identifying each receiving terminal and picture contents transmitted from the transmitting terminal;
• and a transceiver configured to transmit and receive information to/from the receiving terminal and the transmitting terminal,
• the transmitting terminal includes a transmitting portion configured to transmit to the deliver server, picture content and information identifying a receiving terminal which receives the picture content,
• wherein the deliver server notifies, based on the information identifying the receiving terminal which receives the picture content transmitted from the transmitting terminal, the receiving terminal of an inquiry as to whether or not the receiving terminal receives the picture content transmitted from the transmitting terminal,
• in case where the receiving terminal has accepted reception of the picture content, the delivery server registers the information identifying the receiving terminal which receives the picture content in the database and allows the receiving terminal to receive the picture content stored in the storage, and
• in response to a request from the receiving terminal, the delivery server transmits the picture content to the receiving terminal.

A delivery server in a content delivery system comprising a transmitting terminal, a receiving terminal, and the deli very server which are connected via a network and configured to transmit picture content from the transmitting terminal to the receiving terminal via the delivery server, the delivery server comprising:

• a storage configured to store a database for registering information identifying each receiving terminal and picture contents transmitted from transmitting terminals;
• and
• a transceiver configured to send and receive information to and from the transmitting terminal and the receiving terminal,
• wherein the transceiver receives a picture content transmitted from a transmitting terminal and information identifying the receiving terminal which receives the picture content,
• the delivery server, based on the information identifying the receiving terminal which receives the picture content transmitted from the transmitting terminal, notifies the receiving terminal of an inquiry as to whether to receive the picture content transmitted from the transmitting terminal,
• in a case where the receiving terminal has accepted reception of the picture content, the delivery server registers the information identifying the receiving terminal which receives the picture content in the database and allows the receiving terminal to receive the picture content stored in the storage, and
• in response to a request from the receiving terminal, the delivery server transmits the picture content to the receiving terminal.

A content delivery method in a content delivery system comprising a transmitting terminal, a receiving terminal, and a delivery server which are connected via a network and configured to transmit picture content from the transmitting terminal to the receiving terminal via the delivery server, the method comprising:

• transmitting by the transmitting terminal a picture content and information identifying the receiving terminal et which receives the picture content to the delivery server;
• based on the information identifying the receiving terminal which receives the picture content transmitted from the transmitting terminal, notifying by the delivery server the receiving terminal of an inquiry as to whether to receive the picture content transmitted from the transmitting terminal;
• in a case where the receiving terminal has accepted reception of the picture content, registering by the delivery server the information identifying the receiving terminal which receives the picture content in a database and allowing the receiving terminal to receive the picture content stored in a storage, and
• in response to a request from the receiving terminal, transmitting by the delivery server the picture content to the receiving terminal.
