Abstract: Innovations in adaptive encoding of screen content based on motion type are described. For example, a video encoder system receives a current picture of a video sequence. The video encoder system determines a current motion type for the video sequence and, based at least in part on the current motion type, sets one or more encoding parameters. Then, the video encoder system encodes the current picture according to the encoding parameter(s). The innovations can be used in real-time encoding scenarios when encoding screen content for a screen sharing application, desktop conferencing application, or other application. In some cases, the innovations allow a video encoder system to adapt compression to different characteristics of screen content at different times within the same video sequence.

Abstract: A method and system for managing delivery of a content stream to a plurality of devices participating in an online conference session, including delivering, to each of the devices, the content stream associated with the online conference session at a first signal quality, receiving an indication signal indicating that a first device is to broadcast the content stream, responsive to the indication signal, increasing a signal quality of the content stream delivered to the first device from the first signal quality to a second signal quality, wherein the second signal quality is higher than the first signal quality, delivering the content stream to the first device at the second signal quality, and delivering the content stream to the rest of the devices at the first signal quality or a third signal quality, wherein the third signal quality is lower than the first signal quality.
