Abstract
Methods of generating video streams including advertisement information sufficient to support advertisement countdown times and other functions such as advertisement auto pause functions are described. In accordance with various embodiments, advertisement duration is determined from one or more messages included in a video stream, e.g., prior to the corresponding advertising segment. A countdown timer is generated from the advertisement information and displayed along with the content of the advertisement segment. Restrictions for different subscribers may be indicated in the advertisement information messages, e.g., with some end users being permitted to fast forward or skip advertisements with other users being required to allow the full normal playback of one or more advertisement segments. The auto pause function, when activated, pauses an ad segment or set of ad segments at a predetermined time before output of the main program resumes thereby making sure none of the main program is missed.
