Abstract: In a music selection mode, a reproduction object deciding unit in an audio reproducing apparatus selects a plurality of pieces of candidate music from music data stored in a storage unit and has a reproducing unit reproduce them simultaneously. An assigned position deciding unit controls an audio processing unit in such a manner as to assign the sound images of the pieces of candidate music respectively to different positions. An input by which one unit of sound is selected from among a plurality of sounds that a user hears from the different positions is entered to an input unit. Then the reproduction object deciding unit determines that music data corresponding to the sound has been selected. This causes a changeover to a normal mode and the selected music data only is reproduced.

Abstract: When digital image signals inputted through an inputting terminal are recorded on a disc, a medium-related information (a serial number in an TOC) of the disc, read from the disc, with a medium-related information reading section is spectrum-spread in an SS additional information generating section and then digital image signals S2 on which the spectrum-spread medium-related information is superimposed in an SS additional information superimposing section are recorded on the disc. When the signals attempt to be reproduced, the reproduction can be performed in the case wherein the medium-related information superimposed on the image signals recorded on the disc is consistent with the medium-related information of the disc on which the image signals are recorded. Thus, copying of the information signals can be limited to the copying for private use.

Abstract: A method of superimposing additional information on a video signal, transmitting it, and detecting the additional information from the transmitted video signal. The additional information is synchronized with a sync signal in the video signal, and generated in N (N?1) unit intervals of one field of the video signal. Some predetermined unit intervals of the additional information generated in N (N?1) unit intervals of one field of the video signal, are phase-inverted. The additional information is identified by detecting the information in unit intervals based on the sync signal in the video signal, and detecting that information in some predetermined unit intervals is inverted. The additional information is identified by detecting the information in unit intervals, and integrating the detection results with the information in inverted predetermined unit intervals inverted.

Abstract: The output device generates the PN code string every second chip interval with reference to the video sync signal, and spectrally spreads the additional information using this PN code string. The spectrally spread additional information is superimposed on the video signal every second chip interval and outputted. Upon receiving the video signal, in the recording device for recording the video signal on a recording medium, the video signal component is canceled each other between the video signal component in the chip interval on which the additional information is superimposed and the video signal component in the chip interval on which the additional information is not superimposed because of the correlation of the video signal in the horizontal direction, and only the additional information is extracted.

Abstract: An image signal to be outputted is divided into two areas or a first area and a second area. In an electronic watermarking information forming section (WM forming section), a spectrum spread signal (electronic watermarking information) is formed as the first additional information so as to be superposed on the first area of the image signal. The spectrum spread signal is superposed on the first area of the image signal by an electronic watermarking information superposing section (WM superposing section). Moreover, in the case where the image signal is recorded on a recording medium, for example, the second additional information is newly superposed on the second area of the image signal. Thus, deterioration of the information signal is suppressed at minimum, and first and second additional information are superposed on the information signal to be capable of transmitting the information signal.
