A request for a first video may be received from an end user device. A video size for the requested first video may be determined. An unused onscreen location to place the requested first video, within one of a plurality of composite mosaic video streams, may be determined. The unused onscreen location may correspond to a location for insertion of video content for output to an onscreen location of an output device. Information identifying the unused onscreen location may be transmitted to a content source of the requested first video. The requested first video based upon the unused onscreen location information may be received from the content source. The requested first video then may be placed with at least one second video into a composite video stream based upon the unused onscreen location, and the composite video stream may be transmitted to the end user device.
