Abstract
Apparatus and methods are provided for inserting advertisements and/or to perform grooming functions after a video, audio and/or data stream has been transrated and/or encrypted. In this manner, ad insertion and grooming can be performed close to the edge of a video distribution network. Transrating and encryption of a program into which content is to be later inserted can be accomplished before the program is transmitted. Thus, a single encrypted version of a program can be transmitted from a central point in the network to multiple recipients, while providing the benefits of subsequent targeted ad insertion or grooming downstream of the central point.
