Companion devices for real-time collaboration in teleconference sessions

A method, comprising:

• transmitting a first request to join a teleconference session from a first computing device associated with a first user identity;
• receiving first teleconference data comprising plurality of streams associated with the teleconference session at the first computing device;
• displaying a rendering of the plurality of streams on the first computing device;
• transmitting a second request to join the teleconference session from a second computing device associated with the first user identity;
• receiving second teleconference data comprising a subset of streams of the plurality of streams at the second computing device;
• and
• displaying a rendering of the subset of streams of the plurality of streams on the second computing device, wherein the subset of streams of the plurality of streams is based at least in part on data indicating an activity level associated with the subset of streams.

A method, comprising:

• generating teleconference data comprising plurality of streams associated with a teleconference session;
• receiving a first request to join the teleconference session from a first computing device associated with a first user identity;
• receiving a second request to join the teleconference session from a second computing device associated with the first user identity;
• communicating the teleconference data to the first computing device;
• and
• communicating a sub-portion of the teleconference data to the second computing device, wherein the sub-portion comprises at least one stream that is selected from the plurality of streams based on an activity level.

A system comprising:

• one or more processing units;
• and
• a computer-readable medium having encoded thereon computer-executable instructions to cause the one or more processing units to
• generate teleconference data comprising a plurality of streams associated with a teleconference session;
• receive a first request to join the teleconference session from a first computing device associated with a first user identity;
• communicate the teleconference data to the first computing device for displaying a primary user interface, the primary user interface including a plurality of core teleconference control elements;
• receive a second request to join the teleconference session from a second computing device associated with the first user identity;
• select at least one stream of the plurality of streams based on an activity level;
• and
• communicate the teleconference data to the second computing device causing the second computing device to display a companion user interface, the companion user interface including a plurality of companion teleconference control elements.
