Abstract

Subscriptions in a video conference may be provided using multiple bit rate streams. A video conference server may receive video streams from each client in a video conference and may receive subscription requests from each client. The subscription requests may include requests to see video streams from specific other clients at a given resolution and / or frame rate. The video conference server may match up the received video streams with the subscription requests in order to send the subscribing clients their desired video streams. The server may also be able to request different versions of video streams from participants (e.g. different resolutions) and / or alter the video streams in order to better comply with the subscription request.

Description

technical field [0001] The present invention relates to video conferencing systems, and more particularly to video conferencing subscriptions using multiple bitrate streams. Background technique [0002] Video conferencing subscriptions allow customers to choose which participants they would like to watch. Video teleconferencing may use an interactive communication technology that allows two and / or more locations to interact simultaneously through two-way video and audio transmission. Video conferencing can use audio and video communication to bring together people in different locations into a meeting. This can be a conversation between two people in a private office (point-to-point) and / or several locations in a large room that can include more than one person in different locations (multipoint). In addition to audio and video transmission of meeting activities, video conferencing can also be used to share documents, computer displays, and whiteboards. Audio / video trans...
