An information transmission method capable of reproducing the atmosphere of a concert hall or a live performance hall, wherein bio-information of a speaker, player, actor or conductor, who serves as a source of speech, sounds or music and/or bio-information of a performer included within an image are multiplexed with respect to information of speech or music and/or information of the image for transmission thereof. At the receiving side, sense stimulation based on the bio-information is provided to the viewer, or information of speech or music and/or information of the image are controlled on the basis of the bio-information to thereby reproduce presence or live appeal.

Information transmission method and device, information recording or reproduction method and device, and recording medium

Disclosed is a data archive system that executes inspection of a recording quality of an optical disc, estimates a recording quality deterioration factor, and informs it to a user, and a method for estimating the recording quality deterioration factor. The data archive system has a server and a data library device. The server has a whole control part, a data library I/F part, and a recording medium. The data library device has multiple recording media, a recording medium storing part, multiple recording/reproducing parts, and a library control part. The recording medium stores attribute information about the recording medium. The whole control part executes first quality inspection on a first recording medium, executes second quality inspection on a second recording medium, refers to attribute information of the recording media recorded on the information recording medium, and controls so that a factor deteriorating the qualities of the recording media may be estimated.

Data archive system and quality inspection method

A method of reproducing audio signals includes the steps of supplying a predetermined audio signal to a speaker array to synthesize surface wavefronts and forming a virtual sound source by the wavefront synthesis; and controlling the audio signal in order to change the position of the virtual sound source in the vicinity of the virtual sound source.

Method of reproducing audio signals and playback apparatus therefor

An apparatus and method to group users based on bio-information of the users. A two-dimensional bio-information space is generated from first and second dimensions which represent, respectively, first and second characteristics of the bio-information of the users. The users are arranged in the bio-information space based on the bio-information, and users are grouped based on the arrangement of the users in the bio-information space. Continuously acquired bio-information is used to re-group users.

Apparatus and method for classifying groups of users

An image recording apparatus in which recording preset information, constituted by a recording start time and a recording end time, is stored for each preset program to be unattended recorded. If there is any overlap between the recording start times and the recording end times of the preset programs that are to be recorded, a warning is generated; and the overlapping preset programs are prioritized for unattended recording.

Image recording apparatus, image recording method and storage medium for recording television programs

A sound characteristic parameter is obtained for an audio signal to be analyzed by analyzing the signal by means of a sound characteristic parameter analyzing section arranged upstream relative to a similarity determining section. A sound signal operation as retrieving key is read out from a retrieving key storage area of a retrieving key memory by a retrieving key audio signal reading section and analyzed by a retrieving key sound characteristic parameter analyzing section to obtain a retrieving key sound characteristic parameter. The similarity determining section compares the sound characteristic parameter obtained from said sound characteristic parameter analyzing section and the retrieving key sound characteristic parameter obtained from said retrieving key sound parameter reading section and determines the similarity of them to retrieve a part of the audio signal to be analyzed that resembles the audio signal operating as retrieving key and obtained from the sound source of the retrieving key.

Information transmission method, information transmission apparatus, information recording or reproducing method, information recording or reproducing apparatus and recording medium

A sound reproduction apparatus capable of providing a target sensation of sound localization to a listener by using a standard head-related transfer function is provided. In a microphone amplifying section, only the high frequency components of a left sound pickup signal and a right sound pickup signal, which are input from a dummy head microphone, are delayed by a delay circuit. Consequently, since the reproduction sound of the low frequency components having small individual differences can be output earlier, a listener in a reproduction sound field space can perceive the sensation of sound localization by the reproduction sound of the low frequency components that arrive earlier. As a result, even when a standard head-related transfer function is used, it becomes possible to enable the listener in the reproduction sound field space to perceive the target sensation of sound localization.

Sound reproduction apparatus and sound reproduction method

A playback apparatus includes a forming section which, on the basis of an audio signal to be played back, forms audio signals on a plurality of channels for emitting sounds from a pair of sound sources, and a signal processing section which, on each of the audio signals formed by the forming section, performs signal processing for forming a targeted sound field. The signal processing section inclines a sound pressure distribution so that, for each sound source, sound pressure levels of sounds emitted from the sound source to a listening position increase in inverse proportion to angles formed between emitting directions of the sounds emitted from the sound source to the listening position and a straight line connecting the pair of sound sources.

Playback apparatus and playback method

A file storage apparatus provides an information management method. The information management method includes correlating one or more electronic files with audible cues relative to audio content reproduced via the file storage apparatus, designating respective time intervals of the audio content during which each of the one or more electronic files can be accessed by the file storage apparatus, and retrieving the one or more electronic files of the file storage apparatus upon a predetermined user input provided to the file storage apparatus during one of the respective time intervals of the audio content.

Information management method, information management program, and information management device

An audio signal is supplied to a loudspeaker array to perform wavefront synthesis. A virtual sound source is produced at an infinite distance using wavefront synthesis.

A sound field reproduction apparatus generates sound field synthesizing parameters according to a relative positional relationship between the listener and the sound source and performs frequency conversion on sound data according to the relative positional relationship. A convolutional operation is conducted on the sound data that are subjected to the frequency conversion and the generated sound field synthesizing parameters in order to synthesize the sound of the sound source of each channel. The synthesized sound is subjected to wave front synthesis for the synthesized sound by using n-channel sound sources to reproduce a sound field in a predetermined area.
