Abstract:
1. A method for sharing, during an ongoing online meeting, an annotation, the method comprising: receiving, at a server computing device from a first computing device, an annotation to a screenshot representing a previously presented portion of an online meeting of which the first computing device is a participant, the screenshot having been captured in response to a trigger event during the online meeting and the screenshot being representable as an image thumbnail, wherein a live screen data is represented by a first arrangement of tiles, wherein an earlier captured screenshot is represented by a second arrangement of tiles, and wherein the trigger event occurs when a number of tiles that include a pixel in the earlier captured screenshot that is different from a corresponding pixel in the live screen data increases past a threshold, the threshold corresponding to a proportion of the tiles; identifying a second computing device participating in the online meeting, the second computing device having not received the annotation; transmitting, over a first communications channel, the annotation from the server computing device to the second computing device for display at the second computing device during the ongoing online meeting; capturing, at the server computing device, a plurality of screenshots each representing a previously presented portion of the online meeting; transmitting each of the plurality of screenshots to the first and second computing devices over a second communications channel; encrypting the annotation prior to transmitting the annotation over the first communications channel; encrypting the plurality of screenshots prior to transmitting the plurality of screenshots over the second communications channel; transmitting the online meeting over a third communication channel without encryption; wherein the first communications channel, second communications channel, and third communications channel are separate communications channels; and wherein the first communications channel and the second communications channel have relatively lower bandwidth than the third communications channel.
