Abstract: Participant systems in an audiovisual (AV) conferencing can, in one embodiment, use methods to ensure that all participants have a common platform to support AV conferencing, such as a common codec, and also attempt to provide higher quality AV conferencing (e.g., better than the common codec) based on available bandwidth and other criteria. The participant systems can use the common codec as a fallback platform when bandwidth or other criteria dictate a reduction in the quality of the AV conferencing. Other embodiments are also disclosed.

Abstract: A method and apparatus of a device that manages a video stream is described. In an exemplary embodiment, the device receives a plurality of packets for a video stream from a transmitting device via a server. The device may additionally store a first packet of the plurality of packets in a first buffer when the first packet is on-time and store a second packet of the plurality of packets in a second buffer when the second packet is late. The device may also further forward a frame from the second buffer to the first buffer when frame is complete.

Abstract: A device implementing a system for multipath connection management may include first and second local communication interfaces, and a processor configured to establish a primary connection for communicating between the first local communication interface and a first remote communication interface of an other device, and a secondary connection for communicating between the second local communication interface and a second remote communication interface. The processor may be configured to transmit application and control data over the primary connection and concurrently transmit a copy of control data over the secondary connection. The processor may be configured to determine that a degradation of the quality of the primary connection is attributable to the other device. The processor may be configured to switch the secondary connection to the first local communication interface and the second remote communication interface. The processor may be configured to transmit a copy of the application and control data over the secondary connection.
