Abstract
A participation device in a multiparty conference call may act as a server device and/or a client device for two-way audio and video (AV) streaming. A server device may encode a requested AV stream into a set of different encoding profiles that may be dynamically determined based on the varying channel conditions and device capacities of the client devices. At least a portion of differently encoded AV streams is selected and dynamically communicated to the client devices for display. Session parameters are determined according to the varying channel conditions and the device capacities of the client devices to create intended sessions. The selected encoded AV streams are communicated utilizing segment-based adaptive streaming techniques such as HTTP. A client device may access to a HTTP session to download an expected AV stream from the server device. The downloaded AV stream may be decoded into different decoding profiles for display as needed.
