Abstract
A method and computing device that provides viewer impression data for a recorded digital video stream. The method receives a digital video stream as a series of segments, and stores it as a recorded digital video stream having a transition between two consecutive segments at a transition position. The method stores a notification tag that is associated with the transition, and that includes a tag position in the recorded digital video stream, a notification mode, and tag data. During playback of the recorded digital video stream, the method generates a play mode status event, and generates a transition notification when the playback encounters the notification tag and, based on the notification mode, the transition associated with the notification tag. The method collects viewer impression data for one of the two consecutive segments from the play mode status event and the transition notification.
