Abstract: Real-time metadata about a plurality of video streams, and information associated with a directed stream, is received. The information includes a plurality of time segments, where time segments correspond to a respective video stream selected by a director for display in the directed stream during the time segment. Additionally, it is determined, based on the information, that the directed stream will display a first video stream during a first time segment. Further, a subsidiary stream is generated for a first group of users. This involves determining to substitute a second video stream for the first video stream during the first time segment, based on real-time metadata and further based on a first set of rules associated with the first group of users. When the first time segment begins, the second video stream is outputted for display in the subsidiary stream.
