The outputs of the omnidirectional microphone and the directional microphones are decomposed into a series of sub-bands and the comparison and equalization is done for each sub-band. The equalized sub-bands…
Detection of unsecure calls by communications device
Granted: July 2, 2019
Patent Number:
10341855
Disclosed are communications devices which can send indications that they are secure, and which can detect when a far end device is not secure (unsecure). A secure device is one that is not connected to a speakerphone or other speaker which is capable of emitting—or actually is emitting—sound which is louder than a certain threshold. If a communication device detects that a remote endpoint is unsecure, the communication device will switch to an unsecure mode. When the switch is made,…

Methods and system for simulated 3D videoconferencing
Granted: June 4, 2019
Patent Number:
10313633
A system and method for manipulating images in a videoconferencing session provides users with a 3-D-like view of one or more presented sites, without the need for 3-D equipment. A plurality of cameras may record a room at a transmitting endpoint, and the receiving endpoint may select one of the received video streams based upon a point of view of a conferee at the receiving endpoint. The conferee at the receiving endpoint will thus experience a 3-D-like view of the presented site.
