Abstract: The system (1) includes an application server system (AP system) (4) and a connection control system (3). Based on equipment specification information transmitted by user equipment (2), the connection control system (3) establishes connection between the AP system (4) and the user equipment (2). The AP system (4) receives a content delivery request transmitted by the user equipment (2) and containing information for identifying main content. The AP system (4) selects advertisement content based on advertisement selection information. The AP system (4) transmits information for specifying the selected advertisement content to the user equipment (2).

Abstract: To provide a call processing time measurement device which can measure the time required to process a measurement-object message to be measured. When a measurement-object message detection module detects a measurement-object message, a response request message transmission module transmits a response request message towards a node designated as a measurement object right after the measurement-object message. A response request message transmission time record module records the transmission time of the response request message transmitted by the response request message transmission module. A response message reception time record module records the reception time of the response message transmitted from the designated node. A processing time calculation module measures the message processing time of the designated node by calculating a difference between the reception time of the response message and the transmission time of the response request message.

The AP system (4) receives a content delivery request transmitted by the user equipment (2). The AP system (4) selects advertisement content based on advertisement selection information. The AP system (4) generates viewing content data in which the selected advertisement content is inserted in main content identified by the content delivery request. The AP system (4) transmits the generated viewing content data to the user equipment (2) if connection with the user equipment (2) is established.

Abstract: To enable the measurement of service time actually spent on the proceeding of a message out of the proceeding of messages. When a measurement-target message detecting device detects a measurement-target message, a latest transmission instruction device requests a response request message transmitting module to transmit a response request message immediately before the measurement-target message to a measurement-target node. Further, an immediate transmission instruction module requests the response request message transmitting module to transmit the response request message immediately after the measurement-target message to the measurement-target node. The response request message transmitting module transmits the response request which is a message to request a response according to each transmission request. A response message received time recording module records the received time of each of the response messages from to the measurement-target node.

Abstract: A content delivery system 1 is equipped with: a maximum communication bandwidth acquisition part 101 configured to acquire a maximum value of a communication bandwidth necessary for transmitting content data identified by content identification information included in playlist information including plural pieces of content identification information for identifying content, as a maximum communication bandwidth; a connection establishment part 102 configured to establish a connection having the acquired maximum communication bandwidth between an application server system and user equipment; and a content transmission part 103 configured to transmit the content data identified by the content identification information included in the playlist information by using the established connection from the application server system to the user equipment.

Abstract: A Web content fetch and delivery system is disclosed. The system comprises a proxy server configured for receiving requests for content from requesting end user browsers and fetching the content from content provider servers over at least one communication network. The proxy server is programmed for maintaining a log of all content fetched including a time of the fetch and the requesting end user browser, and storing associations between content fetched within a fixed time period by the same requesting end user browser. When subsequent requests for particular content are received by the proxy server, the proxy server will pre-fetch all content associated with that particular requested content.

Abstract: Provided in a proxy server which enables a plurality of SIP servers to copy registration information after presenting, to an SIP server requesting SIP Digest authentication, properness of one who makes an access and of a REGISTER request to be transmitted. With a REGISTER request generation function provided in addition to a function that a common SIP proxy server holds, a proxy server disposed between a user agent and an SIP server generates a REGISTER request to a spare SIP server and transmits the same to the spare SIP server, thereby realizing registration information copying, and holds a user identifier and a password of the proxy server to execute Digest authentication with the spare SIP server. Moreover, after confirming a REGISTER request processing completion response (200 OK) from a working SIP server from which registration information is copied, the proxy server transmits a copied REGISTER request to the spare SIP server.

Abstract: To obtain a content distribution system in which the load placed on a distribution server is reduced, the installation cost and the operational cost are reduced, introduction can be easily realized in a large area, and clients only wait short periods for playing back. A distribution server device converts a content into stream data using an algorithm of near video on demand, and transmits the stream data to an end-system multicast tree established among plural client devices requesting playback of the content. The client devices relay the received stream data of the near video on demand in accordance with the end-system multicast tree.

Abstract: A pushbutton tuner has a plurality of presettable pushbutton actuator assemblies. Each of the pushbutton actuator assemblies comprises a slide mounted on a support so as to be movable between a forward inoperative position and a rearward operative position and normally biased into the inoperative position, a control member pivotally mounted on the slide and having an upstanding pin mounted thereon and being adjustable positionable relative to the slide, a preset member for releasably locking the control member to the slide, and a pushbutton carried by the preset member and having a forward end of the slide slidably received therein. The pushbutton actuator assemblies are disposed in a direction transverse to a movable part of a tuning element.
