Abstract: A detection device includes a signal output unit configured to output a 1-bit first digital signal representing a waveform of a predetermined pattern or a signal based on the first digital signal to a transmission line as a measurement signal, a signal reception unit configured to receive a response signal including a signal reflecting the measurement signal from the transmission line and convert the response signal into a 1-bit second digital signal, an operation unit configured to perform a logical operation of the second digital signal converted by the signal reception unit and a 1-bit third digital signal based on the predetermined pattern, and a detection unit configured to detect an abnormality of the transmission line, based on an operation result obtained by the operation unit.

Abstract: When a retrieval keyword that requires contents is transmitted to a server, the server retrieves contents from a database based on the retrieval keyword, and generates page information including retrieved list information of contents, and appending information that displays whether or not the page information is provided with a consecutive reproduction function of making a terminal device consecutively reproduce part of contents included in the list information respectively to the page information, and transmits the page information. The terminal device displays a list of contents on a display unit based on the page information, and displays an icon in case the list is provided with the consecutive reproduction function to demonstrate that the consecutive reproduction is possible.

Abstract: A server provides a predetermined service for portable terminals (musical piece data of a musical piece to be reproduced at a time of reception of an incoming call) to a portable terminal, and supplies information about the provided service for portable terminals (purchase information) (an ID of the musical piece and the like) to a server. On the basis of the purchase information, the server transmits an electronic mail recommending a service for stationary terminals (a movie using the provided musical piece as a theme song) related to the service for portable terminals provided to a user to the portable terminal. The user can specify the service for stationary terminals to be provided using the electronic mail.
