Abstract: A method, computer system, and computer program product are provided for securely controlling playback of a recorded collaboration session. A plurality of video feeds is received from a plurality of client devices of users participating in a video meeting, wherein each video feed is encoded by each client device in an encoded format that distorts the video feed, wherein a unique key is used by each client device to encode the video feed. The plurality of video feeds are stored in the encoded format. A request is received to view a stored video feed, wherein the request includes the unique key used to encode the stored video feed. In response to determining that the requesting entity is authorized by a user of the stored video feed to view the stored video feed, the stored video feed is decoded and provided to the requesting entity.

Abstract: In one embodiment, a method for selecting video channels is implemented on a computing device and includes: presenting at least one set of detected facial images, detecting user selection of a selected set of detected facial images, where each of the at least one set is associated with one of the video channels; and sending a video channel switching command to a video channel playing device, where the video channel switching command indicates a switch to the video channel associated with the selected set of detected facial images.

Abstract: In one embodiment, a method for detecting faces in video image frames is implemented on a computing device including: comparing current image frames to previously processed image frames to determine similarity, if a current image frame and a previously processed image frame are dissimilar, comparing a location within the current image frame for at least one detected facial image to a location within an associated image frame for at least one most recently stored facial image stored in a most recently used (MRU) cache, if the compared locations are dissimilar, comparing the at least one detected facial image to the at least one most recently stored facial image stored in the MRU cache to determine similarity, and storing the at least one detected facial image in the MRU cache if the at least one detected facial image and the at least one most recently stored facial image are not dissimilar.
