Abstract: When the user of a receiving apparatus presses a notice button provided for a remote controller to indicate the preference concerning the person or thing appearing on the screen of the program being viewed, the corresponding signal is transmitted to the receiving section of a set-top box. A view-log storage section stores an input operation command (including the signal indicating that the notice button has been pressed) together with the receiving time thereof as a view log. A view-information generating section reads the view log, generates a view-information packet, and outputs it to a bidirectional communication section. The bidirectional communication section transmits the view-information packet input from the view-information generating section to a broadcasting apparatus through a bidirectional communication network.

Abstract: The present invention provides a recording/reproducing apparatus capable of realizing proper recorded-content management on a large-capacity storage device. The content data recorded on the recording medium is managed with the content age computed by a lapse time from its recording date-and-time and a genre, and automatically deleted with priority of higher content age. Meanwhile, the user is allowed to instruct delete-prohibition management on a content not desired for automatic deletion. The content data placed under delete-prohibition management is excluded from a subject of automatic deletion. Meanwhile, concerning the delete-prohibition management, an upper limit value is provided. By disabling to unnecessarily placing a great deal of content data under delete-prohibition management, secured is a recording domain during automatic picture-recording or so.

Abstract: In order to execute a flow control and a congestion control in a hop-by-hop manner in a data communication among computers connected to different networks, in a data communication between a client A1 and a remote server B, a communication proxy of the remote server B is located in a local server A in an LAN to which the client A belongs. A communication packet to be routed to the remote server B is stolen (received) and passed to a transport layer. A TCP communication between the client A1 and the remote server B is divided into two; a communication between the client A1 and the communication proxy of the remote server B and a communication between the communication proxy of the remote server B and the remote server B.

Abstract: In order to execute a flow control and a congestion control in a hop-by-hop manner in a data communication among computers connected to different networks, in a data communication between a client Al and a remote server B, a communication proxy of the remote server B is located in a local server A in an LAN to which the client A belongs. A communication packet to be routed to the remote server B is stolen (received) and passed to a transport layer. A TCP communication between the client Al and the remote server B is divided into two; a communication between the client Al and the communication proxy of the remote server B and a communication between the communication proxy of the remote server B and the remote server B.

Abstract: This invention provides dynamic balance of the traffic among data processing devices interconnecting networks and thereby improve the networking performance. For network traffic flowing between a first network and a second network, the traffic is distributed among the data processing devices that act as routers according to the traffic amount. An algorithm for balancing the traffic is used to select appropriate data processing devices as routers.
