US 2019/0104163 A1 · MULTIWAY AUDIO-VIDEO CONFERENCING

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.

Dependent claims

A device, comprising:

at least one processor;
and
a memory including instructions that, when executed by the at least one processor, cause the at least one processor to:
receive, from a sending device, indication of a first content stream and a first stream identifier associated with the first content stream;
receive, from the sending device, indication of a second content stream and a second stream identifier associated with the second content stream, wherein the first content stream and the second content stream correspond to different bit rates of streaming content, and wherein the first stream identifier is different than the second stream identifier;
receive, from a receiving device, a request to subscribe to the second content stream, the request including the second stream identifier;
receive, from the sending device, an indication that the second stream identifier has been associated with the first content stream;
and
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.

6 more elements

A method, comprising:

receiving, by a first device, a set of content streams available by a second device and an indication of whether a parity stream is available for each content stream within the set of content streams;
subscribing, by the first device, to a content stream from among the set of content streams;
subscribing, by the first device, to a parity stream for the content stream in a case where the parity stream is available for the content stream;
providing, by the first device, indication of subscribing to the content stream and the parity stream to a server;
and
receiving, from the server, the content stream and the parity stream.
