Abstract: A method for conducting a communications session (e.g., a teleconference) may include: displaying, by a client device, a communications interface that may include a first canvas, a second canvas, and a content browser. The first canvas may be arranged to display a media stream. The second canvas may be arranged to display a sequence of content items that may be provided by a communications system (e.g., a teleconferencing system). The content browser may be arranged to display identifiers for one or more files that are associated with the teleconference. The method may further include detecting a first input that moves a file from the content browser onto the second canvas, and in response to the first input, transmitting from the client device to the communications system, an instruction to generate a new sequence of content items based on at least a portion of the file.

Abstract: A video image storage and retrieval system providing computer displays of timelines for video sequences, in which a first timeline shows time divisions for segments for the longer sequences, and the other timelines each provide for locating images within the segments. Timecodes in the other timelines are aligned with those in the first timeline so that searching for images in the other timelines is facilitated.
