This disclosure describes a conferencing system with spatial rendering of audio data. The conferencing system includes a local conferencing device that includes a plurality of microphones, an audio encoder, and a spatial encoder that are associated with a local endpoint. The conferencing system further includes a remote conferencing device that includes a plurality of speakers, an audio decoder, and a spatial renderer that are associated with the remote endpoint. The spatial renderer is configured to superimpose a coordinate system for the plurality of speakers and a coordinate system for the plurality of microphones during spatial rendering of the audio data.

Conferencing system with spatial rendering of audio data

This disclosure describes a system for negotiating video camera and display capabilities in a video conferencing environment. The system includes a local camera; a local communication device; and a session negotiation device where the session negotiation device further comprises a processor, memory, and a storage. The processor executes a sequence of computer programmable software instructions that further includes determining negotiation information associated with the local camera; defining the determined negotiation information in a predetermined format compatible with the remote display; applying the determined negotiation information for negotiating capability of the local camera and the remote display for data communication; sending the determined negotiation information to the remote display; mapping data streams from the local camera to the remote display using the determined negotiation information; and defining a predetermined layout of the mapped data streams on the remote display based on the determined negotiation information.

Method and apparatus for negotiating video camera and display capabilities in a video conferencing environment

Voice over internet protocol (VoIP) devices and conferencing systems may include a spatial encoder associated with a first endpoint and a spatial renderer associated with a second endpoint. The spatial renderer may configured to receive audio data. The audio data may be rendered among a plurality of speakers based on a first set of spatial information for a plurality of microphones associated with the first endpoint, and a second set of spatial information for the plurality of speakers associated with the second endpoint. A method for generating a sound field may include determining spatial information for a plurality of microphones in a local room, determining spatial information for a plurality of speakers in a remote room, mapping the spatial information for the plurality of microphones and the spatial information for the plurality of speakers, and generating a sound field in the remote room based on the mapping.

VOIP device, VOIP conferencing system, and related method

This disclosure describes a system and method for negotiating video camera and display capabilities in a multi-camera/multi-display video conferencing environment. The method includes the at least one processor () determining negotiation information associated with a group of local devices (). The negotiation information includes relative spatial information and data stream characteristics. The method also includes the at least one processor () defining the determined negotiation information in a predetermined format compatible with at least one remote device (). The method further includes the at least one processor () applying the determined negotiation information for negotiating capability of at least one device (-) among the group of local devices () and the at last one remote device () for data communication.

Methodology for negotiating video camera and display capabilities in a multi-camera/multi-display video conferencing environment

Embodiments include methods and apparatuses for echo cancelation involving multiple audio channels and the production, sensing, or a combination thereof of multiple audio channels in conferencing systems. A conferencing apparatus with a plurality of speakers configured to generate outgoing acoustic waves responsive to a multi-channel audio signal. One or more microphones are configured to sense incoming acoustic waves from the plurality of speakers and from locally produced acoustic waves from a participant of a conference to generate one or more incoming audio signals. A processor is operably coupled to the plurality of speakers and the one or more microphones. The processor is configured to perform acoustic echo cancelation on the one or more incoming audio signals relative to at least two different channels of the multi-channel audio signal.
