Synchronized out-of-order live video encoding for reduced latency

Techniques for synchronized out-of-order live video encoding are described. As one example, a computer-implemented method includes receiving a first real-time encoded live video, that is in a coded order that is different than a display order, at a content delivery service from a contribution encoder at a different location than the content delivery service, performing, in the coded order, a real-time decode of the first real-time encoded live video by a distribution decoder of the content delivery service to generate a decoded video in the coded order, performing, in the coded order, a real-time encode of the decoded video by a distribution encoder of the content delivery service to generate a second real-time encoded video in the coded order without waiting on a reordering of the decoded video into the display order, and transmitting the second real-time encoded video in the coded order to a client device.

VIDEO CAPTURE WITH FRAME RATE BASED ON ESTIMATE OF MOTION PERIODICITY
20170359549 · 2017-12-14 · ·

Video capture is described in which the video frame rate is based on an estimate of motion periodicity. In one example, a period of motion of a moving object is determined at a sensor device. A frame capture rate of a video camera that is attached to the moving object is adjusted based on the period of motion. Video frames are captured at the adjusted frame rate, and the captured video frames are stored.

Unified, browser-based enterprise collaboration platform

A system for enterprise collaboration is associated with an overlay network, such as a content delivery network (CDN). The overlay network comprises machines capable of ingress, forwarding and broadcasting traffic, together with a mapping infrastructure. The system comprises a front-end application, a back-end application, and set of one or more APIs through which the front-end application interacts with the back-end application. The front-end application is a web or mobile application component that provides one or more collaboration functions. The back-end application comprises a signaling component that maintains state information about each participant in a collaboration, a connectivity component that manages connections routed through the overlay network, and a multiplexing component that manages a multi-peer collaboration session to enable an end user peer to access other peers' media streams through the overlay network rather than directly from another peer. Peers preferably communicate with the platform using WebRTC. A collaboration manager component enables users to configure, manage and control their collaboration sessions.
