   Ad Insertion

Ad insertion is the process of inserting an advertising message into a media stream such as a television program. For broadcasting systems, Ad inserts are typically inserted on a national or geographic basis that is determined by the distribution network. For IP television systems, Ad inserts can be directed to specific users based on the viewer's profile.

This figure shows how an ad insertion system works in an IPTV network. This diagram shows that the program media is received and a cue tone indicates the beginning of an advertising spot. When the IP router receives the cue tone, it informs the ad server that an ad is required and the ad server matches the group ad requirements to specific advertising messages. These messages are associated with group identification codes that are sent to the ad splicer which splices (attaches) each ad to the appropriate media stream. The resulting streams are sent through the IP router to their appropriate recipients.
