Abstract: A system may provide for the generation of spatial audio for audiovisual conferences, video conferences, etc. (referred to herein simply as “conferences”). Spatial audio may include audio encoding and/or decoding techniques in which a sound source may be specified at a location, such as on a two-dimensional plane and/or within a three-dimensional field, and/or in which a direction or target for a given sound source may be specified. A conference participant's position within a conference user interface (“UI”) may be set as the source of sound associated with the conference participant, such that different conference participants may be associated with different sound source positions within the conference UI.

Abstract: A device may include a processor configured to monitor a user of a video conferencing application. The processor may be further configured to determine that the user corresponds to a passive user based on the monitoring; switch a setting for the video conferencing application for the user from real-time video to video streaming, in response to determining that the user corresponds to a passive user; generate a delay between receiving content via the video conferencing application and playing the content by the video conferencing application, wherein the delay progressively increases from no delay to a particular delay value over a time period, in response to switching the setting for the video conferencing application for the user from real-time video to video streaming; and play the received content using the video conferencing application based on the generated delay.

Abstract: A method receives first and second copies of a video stream by first and second video processing devices, respectively, and processes the first and the second copies of the video stream to generate first and second statistical data for the video stream, respectively. The method transmits in first and second transmissions the first and the second copies of the video stream with the first and the second statistical data respectively from the first and the second video processing device to a third video processing device, and reads the first and the second statistical data from the first and the second transmissions by the third video processing device. The method then combines the first and the second statistical data with one copy of the video stream by the third video processing device, and transmits the one copy of the video stream with the first and the second statistical data.

Abstract: A method is provided to synchronize Adaptive Bit Rate (ABR) video streams created from a single baseband video signal that is distributed through multiple different length coax transmission lines to different video encoders. The method inserts a marker in the baseband signal of the Serial Digital Interface (SDI). The baseband signal is then split with the inserted regular markers and distributed to encoders over different length coax transmission lines. Synchronizing the baseband video can then be performed using baseband receivers provided with the different encoders. A marker can be proprietary or can be based on timing standards for SDI such as vertical interval time code (VITC).

Abstract: A multipass encoder is provided with heterogeneous codecs. In one example the system includes a MPEG-4 encoder to perform a less complex first pass encoding followed by a second pass more complex HEVC encoder. The system allows for a faster development cycle of a multipass encoder for a newly introduced codec by reusing the infrastructure and multipass design of an established video encoder already dealing with older technology. This multipass system allows bringing existing technology to a new codec with the constraints of the pre-existing codec limitations, particularly in terms of CPU cycles, to make use of the new codec more economically practical.
