Automatic Detection Of Presentation Surface and Generation of Associated Data Stream

Abstract:

Techniques for automatic detection of a presentation surface and generation of an associated data stream include receiving, in connection with a communication session, a first media stream capturing a portion of an environment including a presentation surface; detecting the presence in the first media stream of the presentation surface; detecting usage of the presentation surface during the conferencing session; generating, in response to the detected usage of the presentation surface, a second media stream dedicated to the presentation surface from the first media stream; and transmitting the second media stream dedicated to the presentation surface to one or more recipient devices.
