Abstract: To provide an information processing apparatus and the like, in which even when a plurality of other information processing apparatuses are connected on a single serial bus system, a required one of the information processing apparatuses can be rapidly and easily selected and the information from the other information processing apparatuses can be input. A receiver R connected to a single serial bus B together with other nodes comprises a host microcomputer 12 for selectively inputting the input information input from a plurality of input terminals and a main microcomputer 13 for acquiring the specified information for specifying the other nodes connected through the serial bus B and setting one node as an alternative of the host microcomputer 12 in place of one of the plurality of the input terminals.

Abstract: To provide a status display apparatus or the like which can permit the user of a plurality of nodes connected by a serial bus according to the serial bus standard to recognize whether the transmission of the audio information or the like has become possible by the connection between the nodes. A status display apparatus included in a receiver R for transmitting/receiving audio information with a player to display the status of the receiver comprises a system control unit 13 and an indicator 15B which makes inquiry about whether the player P has a configuration for transmitting/receiving the audio information to/from the receiver R and upon confirmation that the player P has the required configuration, displays that the player P has such a configuration.

Abstract: A remote control device which remotely controls an electronic apparatus including: a recording device which records control information that defines each of operations of processes in the electronic apparatus; a control device which displays an operation screen on which a plurality of selection images for a selection of each of the processes that are defined by the control information are arranged; an instruction input device which includes at least an operating element that is located on a surface of the display device and has an operation area which accepts an input operation according to the selection images selected by a user; and a sending device which sends at least a part of the control information in correspondence with the input operation by the user on the instruction input device, wherein the control device changes the operation screen which is to be displayed on the display device in response to the input operation by the user and simultaneously the operation area in the operating element in respo

Abstract: In a recording unit, a set state table in which various parameters which are required are stored when a sound processing unit performs signal processing for audio data that corresponds to each channel, and a setting screen data are recorded. This setting screen data is linked to the set state table, so that the set state table is altered in accordance with alteration performed on this setting screen. As a result, the parameters that are used when the sound processing unit performs signal processing for audio data are altered.
