Abstract: A device implementing a system for audio-video conferencing using multiple stream identifiers includes a processor configured to receive, from a sending device, indication of a first content stream and a first stream identifier, and indication of a second content stream and a second stream identifier associated. The first content stream and the second content stream correspond to different bit rates of streaming content. The processor is configured to receive, from a receiving device, a request to subscribe to the second content stream, the request including the second stream identifier, and receive, from the sending device, an indication that the second stream identifier has been associated with the first content stream. The processor is configured to forward, to the receiving device, the first content stream based on the request to subscribe to the second content stream and on the indication that the second stream identifier has been associated with the first content stream.

Abstract: A device implementing a system for multiway audio-video conferencing includes a processor configured to receive (402), from a first device, indication of a first channel and a second channel for communicating content for an audio-video conference session. The first channel and the second channel correspond to different types of communication interfaces. The processor is further configured to receive (404), from the first device, a first request to subscribe to a first content stream for the audio-video conference session via the first channel, and to subscribe to a second content stream for the audio-video conference session via the second channel, and in response to receiving the first request, forward (406), to the first device, the first content stream via the first channel.
