The present technology relates to an information processing apparatus, an information processing method, and a program that enable a configuration of a head mounted display (HMD) to be simplified. There is provided a generation unit configured to generate: first location data regarding a location of self with respect to a real space; second location data regarding a location of another device with respect to self; and third location data regarding a location of the another device with respect to the real space on the basis of the first location data and the second location data. On the basis of the third location data, image data of an image localized in the real space and to be displayed by the another device is generated.

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.

Audio reproducing apparatus and audio reproducing method, allowing efficient data selection

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 Son 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.

Robot system and robot apparatus control method

A spread code string containing a plurality of chips per interval in one horizontal interval or containing a plurality of chips per interval in one vertical interval is generated synchronously with the vertical sync signal at the generation star timing having a period of one vertical period or having a period of a plurality of vertical periods. The generated spread code string repeats over a plurality of horizontal intervals or a plurality of vertical intervals so that the chips having the same data are arranged in spatial direction of the vertical direction or the time axis direction in picture unit. The additional information is spectrally spread so that the chips having the same data are arranged at least in the interval in each 1 horizontal interval or in each 1 vertical interval of the above-mentioned repetition interval, and the generated spectral spread signal is superimposed on the video signal. Thereby, the additional information spectrally spread and superimposed on a video signal is prevented from being removed and being deteriorated, and the quantity of additional information to be superimposed on the video signal is increased.

A method and a system for reliably supplying information about an electronic device employed as a primary information signal receiver device to an electronic device employed as a primary information signal sender device via an existing analog transmission line or digital serial transmission line. A set top box (STB) employed as the primary information signal sender device and a VTR (video tape recorder) employed as the primary information signal receiver are connected to each other via an analog transmission line. A device information transmitter of the VTR supplies an electric signal representing device information indicating the device type and the operation status of the primary information signal receiver device over the analog transmission line via which the STB and the VTR are connected to each other thereby transmitting the device information associated with the VTR in a reverse direction to the STB via a path including an analog input terminal of the VTR, the analog transmission line, and an analog output terminal of the STB.

Information signal reception and transmission apparatus and method

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&#x2267;1) unit intervals of one field of the video signal. Some predetermined unit intervals of the additional information generated in N (N&#x2267;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.

Method and device of superimposing an additional information signal on a video signal and detecting said additional information from said video signal

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.

Video signal transmission method, superimposed information extraction method, video signal output device, video signal recording device, and video signal recording medium

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.

The novel constitution enhances the secrecy of the additional information and the performance of its detection.

ADDITIONAL INFORMATION TRANSMISSION METHOD, ADDITIONAL INFORMATION TRANSMISSION SYSTEM, INFORMATION SIGNAL OUTPUT APPARATUS, INFORMATION SIGNAL PROCESSING APPARATUS, INFORMATION SIGNAL RECORDING APPARATUS AND INFORMATION SIGNAL RECORDING MEDIUM

When digital image signals fed in through an input terminal are to be recorded on a disc, medium-related information, such as a serial number recorded in a table of contents of the disc, is read from the disc and is spectrum-spread in a spectrum spreading additional information generating section and then the digital image signals on which the spectrum-spread medium-related information has been superimposed in a spectrum spreading additional information superimposing section are recorded on the disc. When the signals are to be reproduced, the reproduction can be performed only if 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 copying for private use.
