Panoramic streaming of video with user selected audio
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.
1. A panoramic video conferencing server configured to:
capture an audio stream via an array of microphones;
de-multiplex the captured audio to extract audio for each of a plurality of audio zones;
determine a region of interest (ROI) for each one of a plurality of client devices to which a panoramic video is currently being streamed based on zoom information captured for said device;
generate for each of the plurality of client devices, a modified audio channel associated with the panoramic video being streamed to said client device, wherein
the modified audio channel is adjusted to coincide with directionality of an audio corresponding to the associated region of interest (ROI) captured for said client device, and wherein
the modified audio channel is adjusted to mute audio corresponding to audio zones other than an audio zone associated with the ROI.
2. The panoramic video conferencing server of claim 1 , wherein the ROI for each client device is determined based on panning information for video being viewed by the client device.
3. The panoramic video conferencing server of claim 1 , wherein the modified audio channel comprises at least two audio zones with enhanced audio.
4. The panoramic video conferencing server of claim 1 , wherein the modified audio channel is amplified for ROI indicated by the ROI calculator.
5. A panoramic video conferencing system comprising:
a server configured to:
capture, via an audio interface, an audio stream via an array of microphones;
de-multiplex, by a channel de-multiplexor, the captured audio to extract audio for each of a plurality of audio zones;
determine, by a region of interest (ROI) calculator, a region of interest (ROI) for each one of client devices to which a panoramic video is currently being streamed based on zoom information captured for said device;
generate for each of the plurality of client devices, by an audio processor, a modified audio channel associated with the panoramic video being streamed to said client device, wherein
the modified audio channel is adjusted to coincide with directionality of an audio corresponding to the associated region of interest (ROI) captured for said client device, and wherein
the modified audio channel is adjusted to mute audio corresponding to audio zones other than an audio zone associated with the ROI.
6. The panoramic video conferencing system of claim 5 , wherein the region of interest (ROI) is determined for each client device based on panning information for video being viewed by the client device.
7. The system of claim 5 , wherein the modified audio channel comprises at least two audio zones with enhanced audio.
8. The panoramic video conferencing server of claim 5 , wherein the modified audio channel is amplified for ROI indicated by the ROI calculator.
9. A non-transitory computer-readable medium comprising instructions which when executed by a server causer a computer to perform a method comprising:
capturing an audio stream via an array of microphones;
de-multiplexing the captured audio to extract audio for each of a plurality of audio zones;
determining a region of interest (ROI) for each one of a plurality of client devices to which a panoramic video is currently being streamed based on zoom information captured for said client device;
generating for each of the plurality of client devices, a modified audio channel associated with the panoramic video being streamed to said client device, wherein
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 wherein
the modified audio channel is adjusted to mute audio corresponding to audio zones other than an audio zone associated with the ROI.
10. The computer-readable medium of claim 9 , wherein determining the region of interest (ROI) for each client device is based on panning information for video being viewed by the client device.
11. The computer-readable medium of claim 9 , wherein the modified audio channel comprises at least two audio zones with enhanced audio.
12. The computer-readable medium of claim 9 , wherein the modified audio channel is amplified for ROI indicated by the ROI calculator.
