Patent ID: 11342001

Abstract:
According to an example embodiment, a technique for zooming one or more images of a video stream into corresponding one or more images of a video signal for rendering together with a spatial audio signal that conveys a spatial audio image representing a range of sound directions that spatially correspond to a respective range of positions in images of the video signal is provided, the technique comprising: receiving the video stream, a plurality of audio signals and audiovisual metadata that defines a spatial relationship between images of the video stream and said plurality of audio signals that serve as basis for said spatial audio signal; determining presence of at least a first sound source and a second sound source depicted in an image of the video stream, wherein respective sounds originating from the first and second sound sources are to be represented in said spatial audio signal by a single directional sound component; determining a first zoom factor threshold for zooming said image of the video stream into a corresponding image of the video signal based at least in part on respective positions of said first and second sound sources in said image of the video stream in dependence of said audiovisual metadata; and zooming said image of the video stream into said corresponding image of the video signal in accordance with the first zoom factor threshold.
