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.
