Embodiments generally disclosed herein include computer-implemented methods for delivery of video content across a network. Such methods comprise a content delivery manager capable of receiving a video stream from a content source for delivery to a end user of a content publisher. The content delivery manager is further capable of detecting a trigger signal within the video stream. For example, the trigger signal can indicate a temporal mark injected into the video stream by the content publisher. During general operation, the content delivery manager processes the trigger signal to determine whether to modify delivery of the video stream to the end user. According to another general embodiment, a computer-implemented method is provided for authorizing delivery of a video stream to an end user.
