Abstract: New description information that can be used for the playback and management of video data is generated. A photographing device (1) is provided with: a target information acquisition unit (17) that acquires position information indicating the position of a predetermined object within a video; and a resource information generation unit (18) that generates resource information including the position information, as description information relating to data of the video.

Abstract: In a remote simultaneous viewing system, zapping for a different group that views a content having the same attribute as that of a content viewed by a belonging group of a user is enabled. A content reproduction portion (22) that reproduces a content; and a group switching portion (25) that switches a belonging group of a user to a different group that views a content having the same attribute as that of the reproduced content are included.

Abstract: A group-viewing assistance device allowing a viewer to perform group-viewing without giving much resistance is realized. A group-viewing assistance server (100) presents a viewing environment list indicating, for each group, which content is under group-viewing, executes processing for causing a person who desires group-viewing to participate in remote communication in a group designated by the desiring person, and causes a viewing apparatus (200) of the desiring person to reproduce a content under group-viewing by the group.

Abstract: While executing a television viewing APP, an engine (112) performs another application. A degree-of-concentration determination unit (131) determines the frequency of operations for the application, and calculates the degree of concentration for the program on the basis of the type of the application and the determination result. When the degree of concentration is high, the presentation controller (140) displays an advertisement relevant to the program, on a display unit (150).

Abstract: A device (100) includes a reception unit (110) that receives a program accompanied by a main advertisement from a device (300), a processing unit (120) that displays a program image on a display unit (140), and an engine (131) that displays the main advertisement on the display unit (140). The engine (131) transmits control information indicating a method of controlling displaying a related-advertisement to a sub-device (200) that receives the related-advertisement related to the main advertisement from a server (400) and displays the received related-advertisement.

Abstract: Positive and negative two terminals of each of a plurality of main speakers constituting an array speaker are connected to each of amplifiers. Then, the main speakers are bridge-driven. Sub-speakers interpolating the main speakers are arranged respectively between the main speakers. Then, the positive and negative terminals of each of the sub-speakers are connected respectively to the terminals of the same polarities of the adjacent two of the main speakers. One sub-speaker receives an average value of the signals provided to the adjacent two main speakers, so that the one sub-speaker interpolates the wavefronts emitted from the adjacent two main speakers.

Abstract: Provided is a video presentation apparatus enabling the user to easily ascertain the associative relationship between video and audio. A video presentation apparatus according to the present invention sets a virtual sound source at the position where a video is being displayed, and forms a sound field that imitates the state of audio being produced from the virtual sound source (see FIG. 3).

Abstract: An audio data processing apparatus and the like are provided in which waveform distortion generated when a virtual sound source moves is resolved so that noise caused by waveform distortion is reduced remarkably. The present invention includes: a step of calculating distances measured at different time points between the position of the virtual sound source and a speaker; a step of, when these distances are different from each other, judging whether the virtual sound source is departing or approaching relative to the speaker; and a step of identifying and correcting the part of waveform distortion depending on departing or approaching.

Abstract: An audio data processing apparatus and the like are provided in which waveform distortion generated when a virtual sound source moves relative to a speaker is processed by linear interpolation so that the speed of correction processing is achieved. This apparatus has: calculating means calculating first and second distances measured at two time points from the position of the speaker to the position of the virtual sound source; identifying means, when the first and the second distances are different from each other, identifying a distorted part in the audio data at the two time points; and correcting means correcting the audio data of the identified part by interpolation using a function.
