Abstract

There is provided a system and method for streaming content to a plurality of devices over a network. A first stream comprising a first live feed is received from a first source, a second stream comprising a second live feed received from a second source, the first live feed synchronized with the second live feed, and a third stream comprising the synchronized first and second live feed generated and sent to each device. An interface is also presented on each device and the live feed displayed therewithin, a request signal indicative of a request for interactive content received, a control signal comprising instructions for retrieving the interactive content from the memory sent to each device, and the interface dynamically modified for causing the retrieved interactive content to be displayed concurrently with the live feed.

the encoding application executable by the processor for receiving from the optimized streaming application the second live feed, synchronizing the first live feed with the second live feed, generating a third stream comprising the sychronized first live feed and second live feed, and sending the third stream to the streaming application; and

the streaming application executable by the processor for receiving the third stream from the encoding application and sending the third stream in multicast to the plurality of devices other than the contributing device at the first latency.

2. The system of claim 1, wherein the second live feed comprises at least one of a webcam feed, a desktop sharing feed, and a whiteboard feed.

3. The system of claim 1, wherein sending the third stream in multicast to the plurality of devices other than the contributing device comprises copying the third stream into a plurality of copied streams and transmitting, after a predetermined time delay, each one of the plurality of copied streams to each one of the plurality of devices other than the contributing device for rendering thereon of the synchronized first live feed and second live feed.

4. The system of claim 1, wherein the memory has stored therein on-demand content and an interactive application executable by the processor for receiving a command signal indicative of a command to integrate the on-demand content to the first live feed and sending the command signal to the streaming application, further wherein the streaming application is executable for receiving the command signal, embedding into the first live feed at least one synchronization pulse indicative of a timing at which the on-demand content is to be integrated to the first live feed, and outputting to the optimized streaming application a first control signal comprising the at least one embedded synchronization pulse.

5. The system of claim 4, wherein the interactive application is further executable for outputting to each one of the plurality of devices a second control signal comprising instructions for causing the on-demand content to be retrieved from the memory, the first control signal to be obtained from the optimized streaming application, the at least one synchronization pulse to be extracted from the first control signal, and the retrieved on-demand content to be integrated to the first live feed in accordance with the timing from the at least one synchronization pulse.

6. The system of claim 4, wherein the memory has stored therein the on-demand content comprising at least one of text, images, videos, animations, presentations, surveys, and voting results.

7.
