Abstract: This sound system includes a first sound device including a plurality of first speakers and a plurality of first microphones, and a second sound device including a plurality of second speakers and a plurality of second microphones. The first sound device includes: a device detector that detects the second sound device connected to a network; a test audio transmitter/receiver that acquires, via the plurality of first microphones, test audio output from the plurality of second speakers; a speaker sound source localizer that performs sound source localization with respect to the plurality of second speakers based on the test audio acquired by the test audio transmitter/receiver; a position calculator that calculates positions of the plurality of second speakers relative to the first sound device; and a position notifier that notifies the second sound device of position information representing the positions calculated by the position calculator.

Abstract: This sound system includes a plurality of sound devices connected via a network, each sound device including: an audio acquirer; a sound source localizer that performs sound source localization; a sound source information exchanger that acquires sound source information relating to the audio acquired by another device; a sound source determiner that determines, when a sound source in the sound source information coincides with the sound source specified by the sound source localizer, whether or not a second sound pressure level of the sound source in the sound source information is higher than a first sound pressure level of the sound source specified by the sound source localizer; and a filter processor that performs filter processing of the audio of the sound source specified by the sound source localizer when the second sound pressure level is higher than the first sound pressure level.

Abstract: An information processing apparatus includes a basic control module and a function extension module. The function extension module includes a storage unit in which extension setting information for enabling the basic control module to control the function extension module to execute a function is stored in advance, and a setting information transmission unit that transmits the extension setting information to the basic control module.

Abstract: A television receiver segments a part of an image depending on image information received from a communication device and pixel information representing the number of pixels in a longitudinal direction and a lateral direction of the image. The television receiver judges a size between the number of pixels in the longitudinal direction and that in the lateral direction in the pixel information, and when it is judged that the number of pixels in the longitudinal direction is larger than that in the lateral direction, displays two screens in which the segmented image and another image are juxtaposed on a display unit.

Abstract: An image display apparatus includes a communication portion that communicates with a plurality of information processing apparatuses in a wired or wireless manner, a display portion, a control portion that controls to receive images to be displayed on screens of the information processing apparatuses for each of the information processing apparatuses in the communication portion and display each of the received images on the display portion concurrently, and an operation portion that receives a data transfer operation between the information processing apparatuses by an operation for each of the images displayed on the display portion.

Abstract: If a device non-compatible with CEC is contained in an input path when a display apparatus is HDMI-connected hierarchically to a plurality of external devices, an external device which has transmitted <Active Source> is selected as an operation object device. A TV (100) is HDMI-connected hierarchically to external devices (an AV amplifier (20a), recorders (10a, 10c), a DVD player (10b)) in a tree shape. The TV (100) receives <Active Source> indicating an active state capable of video output from the DVD player (10b) and transmits <Set Stream Path> for switching the input path to the DVD player (10b). When a device non-compatible with CEC (AV amplifier (20a)) is contained in the input path which transmits <Set Stream Path>, the TV (100) selects the DVD player (10b) specified <Active Source> as an operation object device.
