Patent number: 10506004Abstract: Various of the disclosed embodiments enable managing and augmenting “comfort noise” during a network call, such as a Voice Over Internet Protocol (VOIP) connection. Particularly, traditional systems typically send machine-generated comfort noise, or a command to generate comfort noise at the recipient, on a channel separate from the conversation content. Some embodiments reduce this overhead by embedding the comfort noise in the media stream. In other embodiments, audio encoding is stopped at the source when the speaker falls silent and the recipient, after detecting the cessation, will generate white noise at its end. These approaches may be used in conjunction with a determination of the available bandwidth and channel parameters.Type: GrantFiled: December 5, 2014Date of Patent: December 10, 2019Assignee: Facebook, Inc.Inventors: Parama Jyothi Reddappagari, Naizhi Li

Patent number: 10469630Abstract: Various of the disclosed embodiments reduce the impact of RTCP overhead by including RTCP information in the media packets themselves. The values in the RTCP headers may be selected based on the context and organized in a unique format for transport in the media packets.

Patent number: 10435049Abstract: Data are transmitted from a secondary station to a master station along a segmented path, wherein two contiguous segments are respectively connected by a node and wherein the path has at least three segments with at least two nodes. The data from the secondary station are split into N data packets, where N is the number of nodes. The data packets are marked distinguishably, each marking corresponding to a particular node on the path. Each data packet along the path is forwarded only to the adjacent node or adjacent station. Each node checks to determine whether the marking of the packet corresponds to the respective node. If so, data from the node are added to the data packet. The data packets are collected in the master station. The data transmission is concluded successfully if all N data packets with data from all N nodes are present.Type: GrantFiled: November 17, 2016Date of Patent: October 8, 2019Assignee: Innova Patent GmbHInventors: Daniel Pfeifer, Bernard Perrin, Gerhard Netzer, Jean-Dominique Decotignie, Philippe Dallemagne
