Video Conferencing Subscription Using Multiple Bit Rate Streams

A computer-readable medium which stores a set of instructions which when executed performs a method for providing video streams subscription, the method executed by the set of instructions comprising:

• registering a plurality of video conference clients;
• receiving, from each of the plurality of video conference clients, at least one source video stream;
• receiving, from at least one of the plurality of video conference clients, at least one video stream subscription request;
• determining whether at least one first stream of the source video streams received from each of the plurality of video conference clients matches the at least one video stream subscription request;
• and
• in response to determining that at least one first stream of the source video streams received from each of the plurality of video conference clients matches the at least one video stream subscription request, sending the matching at least one first stream of the source video streams to the requesting at least one of the plurality of video conference clients.

A system for providing subscriptions in a video conference, the system comprising:

• a memory storage;
• and
• a processing unit coupled to the memory storage, wherein the processing unit is operative to:
• receive a plurality of video streams from a plurality of video conference clients, wherein each client sends at least one of the plurality of video streams;
• receive at least one subscription request from at least one of the plurality of video conference clients, wherein the subscription request comprises a request for at least one of the plurality of video streams, a requested resolution, and a requested frame rate;
• determine whether the requested at least one of the plurality of video streams is being received from a source client for the requested at least one of the plurality of video streams in the requested resolution and the requested frame rate;
• in response to determining that the requested at least one of the plurality of video streams is not being received from a source client for the requested at least one of the plurality of video streams in the requested resolution and the requested frame rate, determine whether the source client for the requested at least one of the plurality of video streams is capable of sending the requested at least one of the plurality of video streams in the requested resolution at the requested frame rate;
• in response to determining that the source client for the requested at least one of the plurality of video streams is capable of sending the requested at least one of the plurality of video streams in the requested resolution at the requested frame rate, send an instruction to the source client for the requested at least one of the plurality of video streams to encode and send the requested at least one of the plurality of video streams in the requested resolution at the requested frame rate to the system;
• and
• send the requested at least one of the plurality of video streams in the requested resolution at the requested frame rate to the at least one of the plurality of video conference clients sending the subscription request.
