Abstract: An information processing device according to an aspect of the present technology includes a storage unit that stores HRTF data corresponding to a plurality of positions based on a listening position, and a sound image localization processing unit that performs a sound image localization process based on the HRTF data corresponding to a position, in a virtual space, of a participant participating in a conversation via a network and sound data of the participant. The present technology can be applied to a computer that performs remote conference.

Abstract: An audio confirmation system includes a voice acquiring section configured to acquire a voice contained in a motion picture; a voice text producing section configured to produce a voice text based on the acquired voice; a determining section configured to determine whether or not the produced voice text and a caption text that is embedded in an image contained in the motion picture correspond to each other; and an outputting section configured to output a result of the determination of the determining section.

Abstract: Digital sound data is encrypted and recorded in a recording medium 200. Information 212 required for decoding the encrypted digital sound data 220 is recorded in a program 211 for controlling the reproduction of sound data separately from the digital sound data 220. This can prevent PCM sound data recorded in the recording medium as a part of a content, from being reproduced separately from the content.

Abstract: In order to form an image by projecting a texture 520 at an arbitrary angle to an arbitrary position on a surface of an object 500 represented as a 3D model, texture data 520 is divided into texture lines 530 having a width of one dot and a length equal to the number of dots on one side of the texture. Then, supposed is a stereoscopic object 540 based on one texture line 530 that the texture line is extended in a light travel direction while possessing color information from an arrangement relationship between the texture line 530, object model 500 and virtual light source in the three dimensional space. The intersecting part 510 between the stereoscopic object 540 and the surface of the object model 500 is defined as a region for rendering the texture line, and thereby a stereoscopic object 540 is rendered onto the defined region.

Abstract: On a screen display, a specialized image effect is easily attained in which near images are made to appear clearly while distant images are seen as blurred. An image is formed on a screen in which for an image pertaining to a background containing far-distance object group for which the depth amount thereof is comparatively large, the source image is made as a semi-transparent processed image for which a two pixel portion thereof is shifted in an upward direction, for an image pertaining to a mid-distance object group the source image is made as a semi-transparent formation processed image for which a one pixel portion thereof is shifted in an upward direction, and for an image pertaining to a near-distance object an upward shifting processing is not performed. For an image after such processing is performed, a near image appears distinctly, a middle-degree distant image appears somewhat blurred and a far-distant image appears still more blurred.

Abstract: A sound controller has a volume controller, which adjusts the output level of a sound processor unit, and a CPU, which sets the gains (or ON/OFF condition) of the volume controller responsive to a scene or situation in a video game, thereby enabling generation of sound that is responsive to individual scenes and situations in the video game, and enabling effective audible enactment for a user of various scenes and situations in the video game.

Abstract: It is an object of the present invention to provide a method of reproducing stream data according to which the synchronization between the reproduction of the stream data such as sound data and the operation of an application can be easily achieved.

Abstract: It is an object of the present invention to provide a method of reproducing stream data according to which the order of reading stream data such as sound data can be controlled. The sound data reproducing processing is implemented by the reading processing portion 200 and the output processing portion 210. The reading processing portion 200 sequentially reads the sound data stored in a CD/DVD 220 to the buffer 161 according to the branch definition file stored in the CD/DVD 220, while the output processing portion 210 sequentially transfers the sound data read out to the buffer 161 to the sound reproducing processor (SPU) 140.
