Abstract: A sound signal processing device includes a plurality of sound signal processing units and a plurality of buffers. Each of the plurality of sound signal processing units belongs to one of a plurality of groups and executes a predetermined process by using a supplied sound signal. The plurality of buffers are provided with mutually different buffer sizes where each of the plurality of buffers is associated with one of the groups and supplies an accumulated sound signal to a sound signal processing unit that belongs to an associated group.

Abstract: An audio signal processing device includes: an output sound signal generator configured to generate from an input sound signal with an input sampling frequency an output sound signal with an output sampling frequency; a plurality of functional blocks configured to perform signal processing on the output sound signal; and a function selector configured to select one of the plurality of functional blocks. The output sound signal generator sets the output sampling frequency according to the internal sampling frequency used in the selected functional block.

Abstract: An information processing system includes a voice acquisition unit configured to acquire voice, a voice distribution unit configured to input the voice acquired by the voice acquisition unit to a plurality of voice processing units that receive voice and perform processing, a detection unit configured to detect an operation state of at least one of the voice processing units, and a control unit configured to control operation of the voice distribution unit, and in a case where the detection unit detects a predetermined operation state of one of the voice processing units determined in advance, the control unit stops input of the voice to at least part of the other voice processing units.

Abstract: In a video signal transmitting device, a basic image generation unit extracts, for each of the color signal component, pixels constituting a frame of the color signal component at a uniform interval two-dimensionally and two-dimensionally arranges the extracted pixels in a prescribed arrangement to generate a prescribed number of color signal basic images. A basic stream generation unit extracts, for each of the color signal basic images, pixels of the color signal basic image generated by the basic image generation unit in a prescribed sequence to generate a basic stream. A link signal generation unit synthesizes a prescribed number of basic streams in the same or different color signal components generated by the basic stream generation unit, encodes bit-length units of the synthesized basic streams to a different bit length, and generates a link signal having a prescribed speed.

Abstract: Light in primary colors RGB modulated in a first modulation optical system is transmitted through a relay lens (36) and further divided into a P-polarized light and an S-polarized light by a PS separation wire grid (37). The S-polarized light is transmitted through a wavelength spectral filter (39) to select red/green/blue light components R1, G1, B1 of 615, 515, 450 nm in wavelength, which are then modulated by a Y1 device (44). The P-polarized light is transmitted through a wavelength spectral filter (46) to select red/green/blue light components R2, G2, B2 of 650, 550, 475 nm in wavelength, which are then modulated by a Y2 device (51). The 3 -primary color lights modulated by the Y1/Y2 devices (44), (51) are combined with each other at a PS composite wire grid (55) to project a synthetic light on a screen.

Abstract: An optical system capable of outputting hi-contrast images and multi-primary color or 3-dimensional images is provided. Light in primary colors RGB modulated in a first modulation optical system is transmitted through a relay lens 36 and further divided into a P-polarized light and an S-polarized light by a PS separation wire grid 37. The S-polarized light is transmitted through a wavelength spectral filter 39 to select red/green/blue light components R1, G1, B1 of 615, 515, 450 nm in wavelength, which are then modulated by a Y1 device 44. The P-polarized light is transmitted through a wavelength spectral filter 46 to select red/green/blue light components R2, G2, B2 of 650, 550, 475 nm in wavelength, which are then modulated by a Y2 device 51. The 3-primary color lights modulated by the Y1/Y2 devices 44, 51 are combined with each other at a PS composite wire grid 55 to project a synthetic light on a screen.
