摘要： A system and method for playing back video feeds includes determining from the video feeds a subset of currently available video feeds, determining a playback layout based on the number of currently available video feeds and playing back the subset of currently available video feeds within the playback layout. The system and method further includes determining at least one change in availability in a given video feed of the plurality of video feeds, updating the subset of currently available video feeds based on the at least one change, updating the playback layout based on the updated subset of currently available video feeds and playing back the updated subset of currently available video feeds within the updated playback layout.

摘要： Methods, systems, and techniques for performing a facet search include receiving facet search commencement user input indicating that a search for a facet is to commence; in response to the facet search commencement user input, searching one or more video recordings for the facet; and displaying, on a display, facet image search results depicting the facet, wherein the facet image search results are selected from the one or more video recordings. An artificial neural network may be used for the facet search, and that network may be trained by generating a facet image training set that comprises training images, with the training images depicting a type of facet common to the training images; and training, by using the facet image training set, that neural network to classify the type of facet when a sample image comprising the type of facet is input to that network.
