Patent number: 11528447Abstract: A video messaging system facilitates a video messaging session between a client device and a remote device. A remote device provides information (e.g., a link) to a client device for connecting to a video messaging session. The client device uses the provided information to connect to the video messaging session between the client device and the remote device. The video messaging session generally includes two-way communication, with at least video information being transmitted by the client device to the remote device, and instructions describing video operations being transmitted by the remote device to the client device. The video operations may include annotating the video, rewinding the video, pausing the video, and various other modifications to the video.
