Abstract: Disclosed herein is a communication system for enabling a first communication apparatus and second communication apparatuses to communicate with one another over a network. The first communication apparatus includes: a detection device; a display control device; a transmission device. The second communication apparatuses includes: a reception device; a notification device; an instruction device; and a registration device.

Abstract: Disclosed herein is an information processing apparatus that controls reproduction of a plurality of recorded contents recorded when distributed from a predetermined one of a plurality of distribution sources to each of which a predetermined channel is allocated, including reproduction control means for controlling so that, where reproduction starting absolute time indicative of reproduction starting time is designated by a user and besides a reproduction object channel is designated by the user, that one of the recorded contents of the reproduction object channel whose reproduction starting absolute time is included in a recording time zone is reproduced from a position thereof corresponding to the reproduction starting absolute time.

Abstract: An information processing apparatus includes a display controller configured to display a first window that includes an information display area in which information associated with content is displayed and a second window having an input box for entering search reference information in the proximity of the first window when predetermined information is selected from the information displayed in the information display area, thereby displaying the selected predetermined information into the input box.
