Abstract: A cloud-based communication system for monitoring a collaboration session. Based on the monitoring, the system identifies a collaboration event that indicates desirability of a break or that a digression from a session topic has or is occurring. When a collaboration event is identified, a prompt is communicated to the facilitator of the collaboration session. The collaboration event may be defined in a variety of ways such as participant fatigue, participant distraction, or the like. The system provides the facilitator with actions to be initiated by the system (automatically or in response to facilitator/user input) to respond to an identified communication event. The actions include initiating a break, acting to avoid or reduce session digressions, and creating a highlight reel of the collaboration session, including a number of unique features enabling more efficient retrieval and/or review of data. A distracted or fatigued participant can be directed to access the highlight reel.

Abstract: Higher Order Ambisonics represents three-dimensional sound independent of a specific loudspeaker set-up. However, transmission of an HOA representation results in a very high bit rate. Therefore compression with a fixed number of channels is used, in which directional and ambient signal components are processed differently. For coding, portions of the original HOA representation are predicted from the directional signal components. This prediction provides side information which is required for a corresponding decoding. By using some additional specific purpose bits, a known side information coding processing is improved in that the required number of bits for coding that side information is reduced on average.
