Abstract
A optimization method for a sound playback performed by a set-top box including at least one speaker, and to which at least one camera is secured. The method include the steps of: acquiring an initial image produced by the camera while the set-top box is in an initial position and in an initial orientation, the set-top box thus using initial audio parameters to optimize the sound playback; then, acquiring at least one current image; analyzing the current image and the initial image to detect a change of position and/or orientation of the set-top box; performing at least one corrective action to optimize the sound playback.
Claims16
An optimization method for a sound playback performed by a set-top box which comprises at least one speaker and to which at least one camera is secured, comprising the steps of:
- acquiring at least one initial image produced by the camera while the set-top box is located in an initial position and in an initial orientation, the set-top box thus using initial audio parameters to optimize the sound playback;
- then, acquiring at least one current image produced by the camera;
- analyzing the at least one current image and the at least one initial image to detect a change of position and/or orientation of the set-top box;
- performing at least one corrective action making it possible to optimize the sound playback following the change of position and/or orientation of the set-top box.
