Abstract
A panoramic video conferencing server is disclosed. The server is operational to capture an audio stream via an array of microphones. The captured audio stream is de-multiplexed to extract audio for a plurality of audio zones. A region of interest (ROI) is determined for a plurality of client devices to which a panoramic video is being streamed. The ROI is determined based on a zoom information which is inputted by any one of the client devices. A modified audio channel associated with the panoramic video being streamed to at least one of the client devices is generated for each of the client devices. The modified audio channel is adjusted to coincide with directionality of an audio corresponding to the associated region of interest (ROI) inputted by the at least one of said client device and the modified audio channel is adjusted to mute audio corresponding to the audio zones other than the audio zone associated with the ROI.
