Information processing apparatus, information processing method, and video sound output system
Provided are an information processing apparatus, an information processing method, and a video sound output system that execute an output process of an acoustic signal in synchronization with a video signal. The information processing apparatus includes a control section that detects a position of a sound source appearing in a video displayed on a screen of a display unit and that uses one or more vibrators to vibrate the display unit and thereby control output of sound such that a sound image of sound in synchronization with the video is localized at the position where the sound source appears on the screen displaying the video. In a case of displaying videos of two or more video sources on individual windows, the control section localizes a sound image of a sound source detected from the video of each video source at a position where the sound source appears in the corresponding window.
1. An information processing apparatus comprising:
circuitry configured to
detect a position of a sound source in a video to be displayed on a screen of a display, the sound source being placed in a plane of an image frame of the video; and
control one or more vibrators to vibrate the display such that sound is localized at a position corresponding to the position, on the screen displaying the image frame of the video, of the sound source placed in the plane.
2. The information processing apparatus according to claim 1 , wherein
a video source of the video is broadcast, an Over the Top (OTT) service, or an externally input video.
3. The information processing apparatus according to claim 1 , wherein
a video source of the video is visual communication.
4. The information processing apparatus according to claim 1 , wherein
the sound is related to a graphic to be displayed on the screen, and
the position of the sound source is a display position of the graphic.
5. The information processing apparatus according to claim 4 , wherein
the graphic is a graphic of a sound agent or a sound assistant.
6. The information processing apparatus according to claim 5 , wherein
the circuitry is further configured to detect a user interacting with the sound agent and control a display position of a character according to a position of the user.
7. The information processing apparatus according to claim 4 , wherein
the graphic is a graphic of On Screen Display (OSD) or User Interface (UI) appearing on the screen, and
the sound is a sound effect associated with the graphic in synchronization with display of the graphic on the screen.
8. The information processing apparatus according to claim 1 , wherein,
the circuitry is configured to, in a case of displaying videos of two or more video sources on individual windows, localize sound of a sound source detected from the video of each video source at a position corresponding to a position of the sound source appearing in the corresponding window.
9. The information processing apparatus according to claim 1 , wherein
the plane is configured such that a video signal of the video is allocated thereto and is stored in a video memory.
10. The information processing apparatus according to claim 1 , wherein
the image frame of the video comprises a plurality of planes, and
the circuitry is configured to place the sound source in one of the plurality of planes according to a type of the video including the sound source.
11. The information processing apparatus according to claim 1 , wherein
the circuitry is configured to detect the position of the sound source based on meta information.
12. The information processing apparatus according to claim 1 , wherein
the sound corresponds to a surgery site, and
the position of the sound source is determined based on a position of the surgery site.
13. The information processing apparatus according to claim 12 , wherein
the sound corresponding to the surgery site is warning sound of bleeding from the surgery site.
14. The information processing apparatus according to claim 12 , wherein
the position at which the sound is localized is determined based on depth information of the surgery site.
15. The information processing apparatus according to claim 1 , wherein
the sound corresponds to a vehicle or a pedestrian, and
the position of the sound source is determined based on a position of the vehicle or the pedestrian.
16. The information processing apparatus according to claim 15 , wherein
the sound corresponding to the vehicle or the pedestrian is warning sound based on the vehicle or the pedestrian.
17. The information processing apparatus according to claim 15 , wherein
the position at which the sound is localized is determined based on distance information or speed information of the vehicle or the pedestrian.
18. An information processing method comprising:
detecting a position of a sound source in a video to be displayed on a screen of a display, the sound source being placed in a plane of an image frame of the video; and
using one or more vibrators to vibrate the display such that sound is localized at a position corresponding to the position, on the screen displaying the image frame of the video, of the sound source placed in the plane.
19. A video sound output system comprising:
a display;
one or more vibrators configured to vibrate the display; and
circuitry to detect a position of a sound source in a video to be displayed on a screen of the display, the sound source being placed in a plane of an image frame of the video, and using the one or more vibrators to vibrate the display such that sound is localized at a position corresponding to the position, on the screen displaying the image frame of the video, of the sound source placed in the plane.
20. The video sound output system according to claim 19 , wherein
the display is at least part of a windshield, a rear window, or a side window of a vehicle.
