Abstract: A data stream selection/output apparatus that selects and outputs a data stream composed of sequentially obtained data. The data stream selection/output apparatus obtains timing information indicating a time at which a first data stream being output should be switched to a second data stream. The data stream selection/output apparatus, in a time period including the time indicated by the timing information, scans the first and second data streams to detect a first boundary between data blocks of the first data stream and a second boundary between data blocks of the second data stream, where the data blocks conform to a transmission protocol higher than Transport Layer of OSI Reference Model. The data stream selection/output apparatus then stops outputting the first data stream at the first block boundary and starts outputting the second data stream at the second block boundary.

Abstract: The data replacement output apparatus 10 determines whether to perform a sequential output of replacement data based on a comparison between (i) the number of units of data constituting replacement object data received during a time period and (ii) the number of units of data constituting replacement data output during the time period. The determination is made each time replacement object data is received while the sequential output of data is not performed. If it determines to perform the sequential output, the data replacement output apparatus 10 outputs replacement data each time data constituting a data stream is received, and outputs non-replacement-object data each time data constituting non-replacement-object data is received while the sequential output is not performed; if it determines not to perform the sequential output, it outputs non-replacement-object data each time a unit of data constituting the data stream is received.

A print information storing unit (104) is a RAM for storing print information, or the like, and reads the print information from the data packet received from the video/data separating unit (102), and stores it.

Abstract: A service system for distributing a chargeable content. The contents distribution system is able to collect a contents use fee while enabling a contents user to use a content at a low cost, and enabling a company that sells the product by increasing the user's appetite for buying the product without running a commercial or the like in the content. The contents user buys a product of a certain company to reduce the use fee of a chargeable content. The contents distribution apparatus manages the purchase history of the user. The contents distribution apparatus discounts the contents use fee based pm the purchase history, and instead charges the company the discount of the contents use fee.

Abstract: A linked electrical connector has a carrier formed with V-cuts. When a series of electrical connectors are separated by a cutter at V-cut portion, corners of the carrier are shaped as chamfered or curved surfaces. Thus, a linked electrical connector can be smoothly inserted in and removed from a connector box.
