Abstract: An information processing method includes: receiving first space information including a first coordinate system of one of a logical space or a physical space, and second space information including a second coordinate system of the other of the logical space or the physical space; receiving first sound localization information indicating a position where a sound image is to be localized in the first coordinate system; and transforming the first sound localization information into second sound localization information indicating a position where the sound image is to be localized in the second coordinate system.

Abstract: A content data processing method generates a first-time code indicating an elapsed time from a start of the live event, generates first content data from first data, which includes the one of the audio or video data, received from the live event by adding, to the first data, the first-time code with a first start time and a first end time associated with the first data, and generates a second-time code indicating a duration associated with the first data reflecting the first start time and the first end time.

Abstract: A video processing method places an object in a three-dimensional space and outputs a video of a live event as viewed from a viewpoint position set in the three-dimensional space. The video processing method sets a first viewpoint position based on a first factor being a factor related to the object. The video processing method also outputs the video of the live event as viewed from the first viewpoint position, receives a second factor being a factor related to a sound of the live event, and calculates a relative position to the object according to the second factor. The video processing method also changes the first viewpoint position to a second viewpoint position based on the calculated relative position, and outputs the video of the live event as viewed from the second viewpoint position.

Abstract: An audio signal processor includes a first block including a first input interface and a first output interface, and a second block including a second input interface and a second output interface. The audio signal processor further includes a routing matrix that is connected to each of the first input interface, the first output interface, the second input interface, and the second output interface. The routing matrix outputs a signal inputted from each of the first output interface and the second output interface, to each of the first input interface and the second input interface.
